Function prototype: int LookuPiconidFromDirectory (Pbyte Presbits, Bool Fic);

parameter:

Presbits: Pointer to the icon or cursor temptation data. Because this function does not verifying resource data, it causes universal protection (GP) errors or returns an undefined value (if PRESBITS does not point to valid resource data).

FICON: Specifies whether it is a sought icon or a cursor. If this parameter is true, the function search icon; if the parameter is a fake, the function searches the cursor.

Return Value: If the function is successful, the return value is best suited for an integer resource identifier for the icon or cursor of the current display device. If the function is invalid, the return value is zero. To get more error messages, call the getLastError function.

Note: In some devices related and device independent format, RT_GROUP_ICON type resource file (RT_GROUP_CURSOR indicator cursor) contains icon (or cursor) data. The LookuPiconldFromDirectory function Searches the resource file that best suits the icon (or cursor) of the current display device and returns its integer identifier. The FindResource and FindResourceEx functions use this identifier to use the MakeintResource Macro to find resources in the module.

The catalog where the icon is located from a resource file with RT_PROUP_ICON resource type (or cursor)

RT_GROUP_CURSOR type), and a specific icon integer resource name is loaded. The LookupiconldFromDirectory function returns an integer identifier representing the icon resource name, which is mostly matched with the current display device.

Loadicon, LoadCursor, loadImage functions use this function to search for specific resource data that best suits the icon or cursor of the current display device.

The function MapDialogRect replaces the coordinates in the specified RECT structure with the conversion coordinates, which allows the structure to create controls within the dialog or positioning dialog. Function prototype: BOOL MAPDIALOGRECT (HWND HDLG, LPRECT);

parameter:

HDLG: Identification dialog. The MapDialogRect function only receives the dialog creates a handle of a created dialog in a function that is invalid for the handle of other windows.

LPRECT: Points to a Rect structure that contains the coordinate coordinates that will be transformed.

Return Value: If the message is processed, the return value is a non-zero value. If the message is not processed, the return value is zero. If you want to get more error messages, call the getLastError function.

Note: The MapDialogRect function assumes the starting coordinate representative dialog unit within the RECT structure. To convert these coordinates from dialog units into pixels, the function retrieval dialog, the current basic unit, and then apply the following formula:

LEFT = (Left * BaseUnitX) / 4; Right = (Right * BaseUnitX) / 4

TOP = (TOP * BASEUNITY) / 8; bottom = (bottom * baseunity) / 8

In many cases, the basic unit of the dialog is the same as the unit that is retrieved by the getDialogbaseunits function. If the dialog template has a DS_setFont type, the basic unit is the average width and height of the characters in the given font, and the unit is pixel.

"No Yes Yes940 MessageBeep Generate Sound YES YES YES941 MessageBox" Function "function: This function creates, display, and action a message box. The message box contains messages and titles defined by the application, plus any combination of predefined icons and PUSHs buttons.

Function prototype: int MessageBox (HWND HWND, LPCTSTR LPTEXT, LPCTSTR LPCAPTION, UINT UTYPE);

parameter:

HWnd: Identify the owned window of the message box that will be created. If this parameter is NULL, the message box does not have a window.

LPText: Pointing a pointer to a string that is ended with NULL and contains a string of the message displayed.

LPCAPTION: Pointer pointed to a string ended with NULL and used for dialog headings.

Utype: Specifies the contents and behaviors of a decision dialog box. This parameter can be a combination of flags in the following flag groups.

Specifies one of the following flags to display buttons in the message box, the meaning of the flag is as follows.

The MB_ABortRetryIgnore: message box contains three buttons: Abort, Retry, and Ignore.

MB_OK: The message box contains a button: OK. This is the default.

MB_OKCANCEL: The message box contains two buttons: OK and Cancel.

MB_RETRYCANCEL: The message box contains two buttons: Retry and Cancel.

MB_YESNO: The message box contains two buttons: Yes and NO.

MB_YESNOCANCEL: The message box contains three buttons: Yes, NO, and Cancel.

Specifies one of the following flags to display icons in the message box: The meaning of the flag is as follows.

MB_ICONEXCLAMATION:

MB_ICONWARNING: An exclamation point appears in the message box.

MB_ICONIONFORMATION:

MB_ICONASTERISK: The icon composed of lowercase letters in a circle appears in the message box.

MB_ICONOSESTION: A problem tag icon appears in the message box.

MB_ICONSTOP:

MB_ICONERROR:

MM_ICONHAND: A Stop Message icon appears in the message box.

Specifies one of the following flags to see the inspirational button: The meaning of the flag is as follows.

MB_DEFBUTTON1: The first button is the default button. If MB_DEFBUTTON2, MB_DEFBUTTON3, MB_DEFBUTTON4 is not specified, then MB_DEFBUTTON1 is the default value.

MB_DEFSUTTON2; the second button is the default button.

MB_DEFBUTTON3: The third button is the default button.

MB_DEFBUTTON4: The fourth button is the default button.

Specifies one of the following flags to display the form of dialog: The meaning of the flag is like.

MB_ApplModal: Continue to work in the window of the HWND parameter identifier, the user must respond to the message box. However, users can move to the window of other threads and work in these windows. Depending on the hierarchy of the window in the application, the user moves to other windows within the thread. The sub-window of all the master message box is automatically invalid, but the pop-up window is not the case. If no MB_SYSTEMMODAL is specified, MB_ApplModal is default. MB_SYSTEMMODAL: In addition to the message box with WB_EX_TOPMOST type, MB_APPLMODAL and WS_EX_TOPMOST are the same. Use the system modal message box to change a wide variety of users, the main damage error requires immediate attention (for example, memory overflow). If it is not those who contact HWnd, this flag does not affect the user's interconnection of the window.

MB_TASKMODAL: If the parameter hwnd is NULL, MB_TASKMODALL and MB_APPLModal are the same in addition to all levels of windows that belong to the current thread. Use this flag when the calling application or library does not have a window handle. However, it still needs to block the input of other window to call the application, not the other threads.

Alternatively, you can specify the following flags.

MB_DEFAULT_DESKTOP_ONLY: The current desktop that receives the input must be a default desktop. Otherwise, the function call failed. The default desktop is a desktop that is running on the user recorded and later.

MB_HELP: Adds a Help button to the message box. Select the Help button or press F1 to generate a Help event.

MB_Right: Text is right adjustment.

MB_RTLREADING: Displays messages and uppercase text from right to left in Hebrew and Arabic systems.

MB_setForeground: The message box changes to the foreground window. The SETFOREGRUNDWINDOW function is called in the internal system.

MB_TOPMOSI: The message box uses the WS_EX_TOPMOST window type to create MB_Service_Notification.

Windows NT: The calling program is a user's service program for notifying events. The function displays a message box on the current event desktop, even if there is no user registered to the computer.

If this parameter is set, the HWND parameter must be NULL. So the message box can appear on a desktop instead of the desktop response parameter hwnd.

For Windows NT 4.0, the value of MB_SERVICE_NOTIFICATION changes. For old and new values, see Winuser.

Windows NT 4.o is mapped to the new value in MessageBox and MessageBoxEx, providing inverse compatibility with the presented service program. This map is only done for the number of available executables.

In order to establish a server with MB_Service_Notification, you can have two options on Windows NT 3.x and Window NT 4.0. In the connection time, specify a version of a version of less than 4.0, or at the connection time, specify a version 4.0 version. In runtime, use the function getversionEx to detect the system version, then use MB_Service_Notification_NT 3.x on Windows NT 3.x to run and run with MB_Service_Notificaion on Windows NT 4.0. MB_SERVCE_NOTIFICATION_NT3.X (Windownt) This value is in response to the MB_Service_notificaion for Windownt3.51

The value defined.

Return Value: If there is not enough memory to create a message box, the return value is zero. If the function call is successful, the return value is one of the menu item values returned by the following dialog: The Idabort: The Abort button is selected. The IDCANCEL: Cancel button is selected. The iDignore: The IGNORE button is selected.

IDNO: No button is selected. The IDOK: OK button is selected. The IDRETRY: RETRY button is selected.

The iDyes: Yes button is selected.

If a message box has a Cancel button, and if the ESC button is pressed or the CANCEL button is selected, the function returns the IDCANCEL value. If the message box does not have a Cancel button, press the ESC key.

Note: When a system modal message box is created, when the system is in the low end of the memory, the string points to by the LPText and LPCAPTION parameters should not be removed from a resource file because it can cause failure.

If the message box is created while the dialog appears, the handle of the dialog box can be used as the HWND parameter, and the HWND parameter should not be identified, such as one of the dialog boxes.

Function prototype: void mouse_event (DWORD DWFLAGS, DWORD DX, DWORD DY, DWORD DWDATA, DWORD DWEXTRAINFO);

parameter:

DWFLAGS: Sign bit set, specify a variety of situations in clicking buttons and mouse action. You can be any reasonable combination of the following values in this parameter:

Moose_Eventf_absolote: Indicates the parameters DX, DY contains a normalized absolute coordinate. If this bit is not set, the parameters contain relative data: the change position relative to the last position. This flag can be set, or not, regardless of the type of mouse or a device that is similar to the mouse connected to the system. To obtain information about the action of the mouse, see the following note section.

MooseEventfmove: Indicates that moves.

M00seEventf_leftdown: Indicates that press the left mouse button.

M00seEventf_leftup: Indicates that the left mouse button is released.

MooseEventf_rightdown: Indicates right mouse button.

MooseEventf_rightup: Indicates Railing Mouse button.

MooseEventf_midddingn: Indicates that the mouse is pressed.

MooseEventf_middleup: Indicates the mouse button.

MooseEventf_wheel: If the mouse has a wheel in Windows NT, it indicates that the mouse wheel is moved. The number of movements is given by DWDATA.

DX: Specifies the number of movements along the absolute position along the X axis or from the last mouse event, depending on the setting of MooseEventf_absolote. The absolute data given as the actual X coordinate of the mouse; gives the relative data as the number of moving mickeys. A MICKEY indicates the number of mouse movements, indicating that the mouse has been moved.

DY: Specifies the number of mouse along the absolute position of the Y-axis or from the last mouse event, depending on the setting of MooseEventf_absolvte. The absolute data given as the actual Y coordinates of the mouse, the relative data given as the number of moving mickeys.

DWDATA: If dwflags is mooseeventf_wheel, DWDATA specifies the number of mouse wheels. The positive value indicates that the mouse wheel is rotated forward, that is, away from the direction of the user; negative value indicates that the mouse wheel is rotated backwards, namely the user. A pointer is defined as Wheel_Delta, ie 120.

If dwflags is not mooseeventf_wheel, the DWDATA should be zero.

DWEXTRAINFO: Specifies additional 32-bit values associated with the mouse event. The application call function getMessGexTraInfo is obtained.

Return Value: None.

Remarks: If the mouse is moved, use the MouseEventf_Move to indicate, DX and DY keep the mobile information. The information given is absolute or relative integer value.

If the MOWSEEVENTF_ABSOLOTE value is specified, DX and DY contain standardized absolute coordinates, which are between 0 and 65535. The event program maps this coordinate to the display surface. The coordinates (0, 0) are mapped to the upper left corner of the display surface, and (6553, 65535) is mapped to the lower right corner.

If not specified, MOWSEEVENTF_ABSOLOTE, DX, and DY indicate the movement of the location generated by the last mouse event (ie the last report). The positive value indicates that the mouse is moved to right (or); negative value means that the mouse is moved to left (or).

The relative movement of the mouse is set from the mouse speed and acceleration level. A end user uses the mouse control panel application to set these values, and the application uses the function SystemParametersInfo to get and set these values.

The system provides two tests for the specified mouse movement when applying acceleration. If the distance from the specified edge of the X-axis Y axis is larger than the first mouse threshold, and the operating system is doubled. If the specified distance along the X-axis or Y axis is larger than the second mouse threshold, and the operating system is 2, the operating system will double from the first threshold test. This allows the operating system to simultaneously move the relative displacement of the X-axis or Y axis to 4 times along the X-axis or Y axis.

Once acceleration is applied, the system is used to convert the synthesized value with the desired mouse speed. The range of mouse speed is from 1 (slower) to 20 (fastest) and represents the number of distance indicators based on mouse movement. The default is 10, indicating that the movement of the mouse is attached.

The application that Mouse_Event needs to be used to synthesize mouse events. It is also used to obtain mouse information other than mouse position and mouse button state. For example, if the input board manufacturer wants to pass the brush-based information to its own application, you can write a dynamic key pick library (DLL) that directly communicate with the input board, obtain additional information, and saves it into a queue. The DLL then calls mouse_event, with standard buttons and X / Y position data, and sets the pointers or indexes of the additional information arranged in the parameter DWEXTRAINFO. When the application needs additional information, call the DLL (along with the pointer or index in DWEXTRALNFO), the DLL returns additional information. Windows CE: Windows CE does not support parameter dwflags to take the moose eventf Wheel constant.

"No Yes YES1014 MOVEFILE NOTY NOY YES YES1015 MOVEFILEEX Change Name File NO YES YES YES YES YES1017 MOVEWINDOW Change Window Location and Size" Function: This function changes the location and size of the specified window. For top-level windows, locations and sizes are relative to the top left corner of the screen: for sub-windows, locations and sizes are coordinates relative to the parent window client area.

Function prototype: BOOL MoveWindow (HWND HWND, INT X, INT Y, INT NWIDTH, INT NHEIGHT, BOOL BREPAINT);

parameter:

HWND: Window handle.

x: Specify the left boundary of the new location of the window.

Y: Specifies the top boundary of the new location of the window.

NWIDTH: Specifies the new width of the window.

NHAIGHT: Specifies the new height of the window.

BREPAINT: Determines if the window is refreshed. If this parameter is true, the window receives a WM_PAINT message; if the parameter is false, no refresh action does not occur. It applies to the client area, non-client area (including the title bar and scroll bar), and the area of the parent window exposed due to the mobile sub-window. If the parameter is false, the application must explicitly enable the window to invalid or redraw this window and the parent window that needs to be refreshed.

Return Value: If the function is successful, the return value is non-zero; if the function fails, the return value is zero. To get more error messages, call the getLastError function.

Remarks: If Brepaint is true, the system sends a WM_PAINT message to the window after the window moves (ie, by the MoveWindow function call UpdateWindow function). If BREPAINT is false, the system places the WM_PAINT message in the message queue of the window. The message loop dispatches only WM_PAINT messages when dispatched in other messages in the message queue.

Function prototype: Bool PeekMessage (lpmsg lpmsg, hwnd hwnd, uint WMSGFILTERMIN, UINT WMSGFILTERMAX, UINT WREMOVEMSG);

parameter:

LPMSG: The MSG structural pointer that receives message information.

HWND: The handle of its message is checked.

WMSGFILTERMIN: Specifies the first message in the message range being checked.

WMSGFILTERMAX: Specifies the last message in the message range being checked.

Wrememsg: Determines how messages are processed. This parameter can remove one of the following:

After the PM_NOREMOVE: PeekMessage process, the message is not removed from the queue.

After the PM_Remove: PeekMessage is processed, the message is removed from the queue.

PM_NOYIELD can be combined to PM_NOREMOVE or PM_REMOVE. This flag allows the system to not release threads waiting for the calling program.

Default, process all types of messages. If you only process some messages, specify one or more of the following values:

PM_QS_INPUT: Windows NT5.0 and Windows 98: Hands mouse and keyboard messages.

PM_QS_Paint: Windows NT 5.0 and Windows 98: Processing Drawing Messages.

PM_QS_POSTMESSAGE: Windows NT 5.0 and Windows 98: Processing all sent messages, including timers and hot keys.

Return Value: If the message can be obtained, return a non-zero value; if there is no message to get, the return value is zero.

Remarks: And the function getMessage is not the same, the function peekmesssge is not waiting for the message before returning to the queue.

PeekMeSSGE only allows messages associated with the window of the parameter HWnd ID or a message that is determined to be in its sub-window, and the message is within the range determined by the parameter WMSGFitermin and WMSGFIHERMAX. If hwnd is NULL, PeekMessage receives messages that belong to the window of the current calling thread (PeekMessage does not receive a message belonging to the window of other threads). If hwnd is C1, PeekMessage only returns a message that the HWND value is NULL, which is sent by the function PostthreadMessage. If WMSGFILTERMIN and WMSGFILTERMAX are zero, getMessage returns all available messages (ie, no range filtering). Constant WM_KEYFIRST and WMKEYLAST can take all keyboard messages as a filter value; constant WM_MOUSEFIRST and WM_MOUSELAST can be used to receive all mouse messages.

PeekMessage usually does not clear the WM_PANT message from the queue. The message will remain in the queue until the process is completed. But if the WM_PAINT message has an empty update area, PeekMessage will clear the WM_PAINT message from the queue.

Windows CE: WM_PAINT messages with a NULL update area are not cleared from Queue.

Function prototype: BOOL Registerhotkey (HWND HWND, INT ID, UINT FSMODIFIERS, UINT VK);

parameter:

HWND: The hotkey generates the window handle of the WM_HOTKEY message. If the parameter null, the WM_HOTKEY message passed to the calling thread must be processed in the message loop.

ID: Define the identifier of the hotkey. The other hotkeys in the calling thread cannot use the same identifier. The application function program must define a value of 0x0000-0XBFFF range. A shared dynamic link library (DLL) must define a value of the DabuBaladDatom function in the 0xC000-0xFFFF range returns to this range). To avoid the conflict conflicts defined with other dynamic link libraries, a DLL must use the GlobalAdDatom function to get the identifier of the hotkey. FSMODIFOERS: Defines the keys that must be pressed together with the keys defined by the NVIRTKEY parameter in order to generate WM_HOTKEY messages. This parameter can be a combination of the following:

MOD_ALT: The pressed can be any Alt key. MOD_CONTROL: The pressed can be any Ctrl key.

MOD_SHIFT: The pressed can be any Shift key.

MOD_WIN: The pressed can be any Windows button. These keys can be recorded in the Microsoft Windows log.

VK: Defines the virtual key code of the hotkey.

Return value: If the function call is successful, a non-value is returned. If the function call fails, the return value is 0. To get more error messages, you can call the getLastError function.

Note: When a key is next, the system is looking for a match in all hot keys. Once a matching hotkey is found, the system will pass the WM_HOTKEY message to the message queue of the thread that is registered with the hotkey. This message is transmitted to the queue head, so it will be removed in the next round message loop. This function cannot associate a hotkey to create a window created by other threads.

If a hotkey definition is defined by other hotkeys, the RegisterhotKey function call failed.

"YES YES YES1155 REMOVEPROP Removes a" function function from the specified window attribute: This function removes an item from the specified window attribute table. The specified string identifies the item to be deleted.

Function prototype: Handle RemoveProp (HWND HWND, LPCTSTSTSTRING);

parameter:

HWnd: Points the handle of the window to change the property item.

LPSTRING: Points to string pointers ending with NULL or contains atoms identifying strings. If this parameter is an atom, it must be created using the AddAM function. Atom is 16-bit data value, it must be placed in the low word of the lpstring parameter,

The high rate must be 0.

Return Value: The return value identifies the specified string. If the string cannot be found in the specified attribute table, then the return value is NULL.

Note: The application must release the data handle associated with the item cleared from the property table. Applications can only clear those properties it adds it does not clear other applications or the properties they join.

The REMOVEPROP function returns the data handle associated with the string so that the application can release data related to the handle. Quick check: Windows NT: 3.1 or above; Windows: 95 or above; Windows CE: does not support; header file: Winuser.h; file: user32.lib; unicode: In the Windows NT environment, Unicode and ANSI version are implemented.

"YES YES YES1156 ReplaceText Establishs Alternative Text Dialog" function. This function creates a system-defined non-Mode dialog that enables users to find or replace a string or perform control and alternative operations.

Function prototype: HWnd ReplaceText (LPFINDREPLACE LPFR);

parameter:

LPFR: The FindReplace structure pointing to a message containing the initialization dialog. The dialog is applied to this structure to transfer the information input by the user to the application. For more information, see the reference portion.

Return Value: If the function call is successful, return the value of the value of the dialog, you can use the window handle to contact or close it. If the function call fails, the return value is NULL. If you want more error messages, call the CommdlGexError function, its return value is as follows:

CDERR_FINDRESFAILURE CDERR_MEMLOCKFAILURURE

CDERR_INITIALIZATION COERR_NOHINSTANCE

CDERR_LOADRESFAILURE CDERR_NOHOOK

CDERR_LOADSTRFAILURE CDERR_BITEMPLATE

CDERR_LOCKRESFAILURE CDERR_STRUCTSIZE

CDERR_MEMALLOCFAILURE FRERR_BUFFERLENGTHZERO

Note: The Pepiace Text function does not perform text alternative operations. Instead, the dialog box transmits FINDSGSTRING to the window function of the dialog window. When the dialog is created, the HWndowner member of the FindReplace structure specifies the dialog window.

Before calling the ReplaceText function, you must call the RegisterWindowMessage function to register the FINDSGSTRING information.

When the user combines the Find next, the Replace All button, or when the dialog is turned off, the dialog function applies these identities to send information.

The iParam parameters in FindMsgString information contain a pointer to the FindReplace structure. The FLAGS members of this structure indicate an event of formal information. Other members in this structure indicate the user's input information.

If you create a Replace dialog, you must apply the ISDIALOGMESSAGE function in the application information chain to ensure that the dialog can correctly handle the chain input information, such as the Tab key, and the ESC key.

IsDialogMessage function return value indicates whether the Replace dialog handles information.

You can provide a FRHOOKPROC hook function for the Replace pair, this hook function can handle information sent to the dialog.

To make a hook function take effect, you can set the FR_ENABLEHOOK flag of the FLAGS member in the FINDREPLACE structure and specify the address of the hook function in the IPFNHOK member.

"YES YES YES1180 SCROLLWINDOW Mobile Window Customer Area" function function: This function scrolls the specified form customer area content. Functions provide backward compatibility, and new applications should use ScrollWindowEx.

Function prototype: BOOL ScrollWindow (HWND hWnd, // handle of window to scroll int XAmount, // amount of horizontal scrolling int YAmount, // amount of vertical scrolling CONST RECT * lpRect, // address of structure with scroll rectangle CONST RECT * LPClipRect // Address of structure with clip reprut;

parameter:

HWND: The customer area will be scrolled by the form handle.

XAMOUNT: Specifies the number of horizontal scrolls in units of equipment. If the form is scrolling mode as CS_OWNDC or CS_CLASSDC, this parameter uses logical units without using device units. When scrolls the content to the left, the parameter value must be negative.

YAMOUNT: Specifies the number of vertical scrolling equipment units. If the form is scrolling mode as CS_OWNDC or CS_CLASSDC, this parameter uses logical units without using device units. When scrolls the content up, the parameter value must be negative.

LPRECT: Points the RECT structure of the customer area portion that will be scrolled. If this parameter is NULL, the entire customer area is scrolled.

LPCLIPRECT: Points to contains the RECT structure similar to the clip scroll bar. Only the bits inside the clip rectangle strip are affected. The inside of the rolling rectangle in the outer direction is colored, and the scroll from the inside of the rectangle will not be colored.

Return value: If the function is running, the return value is non-zero; if the function is running, the return value is zero. If you want to get more error messages, call the getLastError function.

Note: If the scrolling rich in the scrolling form will automatically hide the ^ compass to prevent it from being wiped; then restore the ^ in the scrolling. The position of the ^ character is thus adjusted. The area that is not covered by ScrollWindow is no longer saga, but it combines into a form of an update area. The application finally finally received the message of WM_Paint, informing it must be redrawn. In order to scroll the unwrapping area while the scrolling process, the UpdateWindow function should be called immediately after calling the scrollwindow function.

If the parameter LPRECT is empty, the position of any subform in the form determines the number of parameters Xamount and Yamount; the form invalid (unloaded) is also off. IPRECT is faster when scrollwindow is empty.

If the parameter LPRECT is not empty, the position of the subform in the form does not change, and the area in which the invalid (unloaded) in the form is not off. In order to prevent LPRECT from being updated in time, the UPDATEWINDOW function is called before calling ScrollWindow.

Return Value: If the function runs successfully, the return value is a SimpleRegion (a rectangular invalid area), the ComplexRegion (non-rectangular invalid area) or NULLREGON (no invalid area) If the function is run, the return value is Error. If you want to get more error messages, call the getLastError function.

Note: If the SW_INVALIDATE and SW_ERASE flags are not set, the function ScrollWindowEx does not fail the scrolling area. If any of the flags are set, the ScrollWindowEx function can make the zone invalid. This area will no longer be updated until the application calls the theupdateWindow function, call the TheredRawWindow function (specify the RDW_UPDATENOW or RDW_ERASENOW flag) or find the WM_PAINT message from the application queue.

If the form has a WS_CLIPCHILDREN type, the return area specified by HrgnUpdate and prcupdate describes the full area of the scroll form that must be updated, including any area of the desired update subscription.

If the SW_ScrollChildren flag is set, the system will not fully update the screen when the child form is scrolled. The scrolling sub-form part located outside the rectangle is not erased, nor is it heavy in its new direction. In order to move the child form, the deferWindowPos function can be used in the rectangular strip specified by PRCScroll. If the flag SW_ScrollChildren is set and the symbol cross scrolls, the cursor is also reset.

All input and outputs are defined as the client if necessary, use IPTODP and DPTOLP function conversion logical correlation.

SMTO_ABORTIFHUNG: If the reception process is in the "hung" state, it will return to the end of the timeout cycle.

SMTO_BLOCK: Blocks calling threads from eliminating any request until the function returns.

SMTO_NORMAL: When calling the thread waiting function to return, it is not prevented from processing other requests.

SMTO_ONTIMEOUTIFNOTHUNG: Windows 95 and later: If the receiving thread is not suspended, do not return when the timeout cycle ends. Utimeout: Specifies the duration of in milliseconds for the timeout cycle. If the message is a broadcast message, each window can use the full overtime cycle. For example, if you specify a 5 second timeout cycle, there are 3 top windows that fail to process messages, and you can have a delay in up to 15 seconds.

LPDWRESULT: Specifies the result of the message processing, depending on the message sent.

Return Value: If the function call is successful, return a non-zero value. If the function call fails, or timeout, the return value is zero. If you want to get more error messages, call the getLastError function. If getlasterror returns zero, it indicates that the function is timeout. If you use hwnd_broadcast, SenddMessAggTimeout does not provide a single window timeout information.
