This function Windows NT and Windows 95 have a great difference. The complete Windows NT is first given in this reference page, and the implementation of the Windows 95 version is given, so that you can better understand the difference between the two. ActivateKeyBoadLayout function in Windows NT activates a different keyboard layout. At the same time, the keyboard layout is set to activity in the process of calling the function in the entire system.

Function prototype: HKL ActivateKeyboardLayout (HKL HKL, UINT FLAGS);

parameter:

HKL: The handle of the keyboard layout will be activated. This layout must first call the LeadkeyBoadLayout function, this parameter must be the handle of the keyboard branch, or one of the following values:

HKL_NEXT: In the loop chain list of the system maintained, the layout of the hex, select the next layout.

HKL_PREV: In the loop chain list of the loaded layout, select the previous layout.

Flags: Defines how the keyboard layout is activated. This parameter can take some of the following values:

LFREORDER: If the bit is set, the loop link of the loaded keyboard layout will be reordered. If the bit is not set, the order of the loop link table is unchanged. For example, if the user activates the English keyboard layout, the French, German, Spanish keyboard layout is sequentially, and then activate the German keyboard layout by setting the KLF_REORDE bit, it will produce the following sequence: German, English, French, Tiya Keyboard layout. If the German keyboard layout is activated, the KLF_REORDER bit is not set, resulting in the keyboard layout of the keyboard layout: German, Spanish, English, French. If the loaded keyboard layout is less than three, the value of the logo domain does not work.

KLF_SETFORPROCESS: Used in Windows NT 5.0 or later. This parameter is used to activate the specified keyboard cloth throughout the process and send a WM_INPUTLANGCHANGE message to all threads of the current process.

KLF_UNLOADPREVLOUS: Uninstall the previously active keyboard layout.

Return value: If the function call is successful, the return value is the handle of the previous keyboard layout. Otherwise, the return value is zero. To get more error messages, you can call the getLastError function.

Note: You can load a variety of keyboard layout at any time, but only one layout can be activated at a time. Mounting a variety of keyboard layouts make it quickly to switch between multiple layouts. The Windows 95 ActivateKeyBoadLayout function sets the input language for the current thread. This function accepts a keyboard layout handle that identifies a partial and physical layout of the keyboard.

"YES YES YES34 APPENDMENU] Add a new item in the menu: This function adds a new menu item at the end of the specified menu bar, drop-down menu, submenu, or shortcut menu. This function specifies the content, appearance, and performance of the menu item. The function appendmenu has been replaced by lnsertmenultem. However, if you don't need the extension of the LnsertMenultem, you can still use the appendmenu.

Function prototype: Bool appendmenu (HMENU HMENU, UINT UFLAGS, UINT UIDNEWLTEM, LPCTSTR LPNEWLTEM);

parameter:

HMENU: The menu bar, drop-down menu, submenu, or handle of the shortcut menu will be modified.

UFLAGS: Controls the appearance and performance of the new menu item. This parameter can be a combination of values listed in the note.

UidNewltem: Specify the identifier of the new menu item, or when the UFLAGS is set to MF_POPUP, the handle of the drop-down menu or submenu is indicated.

LpNewltem: Specifies the contents of the new menu item. The meaning of this parameter depends on whether the parameter uflags contains the MF_bitmap, the MF_OWNERDRAW or MF_STRING flag, as shown below:

MF_bitmap: With bitmap handles. MF_String: The pointer of the string ended with `/ o '.

MF_OWNERDRAW: The 32-bit value containing the application application can reserve additional data related to the menu item. This value is in the message WM_MEASURE or WM_DRAWITEM, which is the structure, or ItemData, or IParam, is located when the menu is created or the appearance is modified.

Return Value: If the function call is successful, return a non-zero value; if the function call fails, the return value is zero. If you want to get more error messages, call the getLastError function. Note: Once the menu is modified, whether it is in the display window, the application must call the function DrawMenubar.

In order to control the keyboard acceleration key to control the retention or the menu items you draw, the owner of the menu must handle the WM_MenuChar message.

See the self-drawing menu and WM_MenuChar message.

The following flags can be set in the parameter uflags:

MF_bitmap: Use a bitmap as a menu item. The parameter LPNewLTEM contains the handle of this bitmap.

MF_CHECKED: Place a pick tag next to the menu item. If the application provides a selection tag, a bitmap (see SetMenulteMaps), place the tag bitmap next to the menu item.

MF_DISABLED: Enables the menu item to make the item can't be selected, but do not make the menu item be grayed.

MF_ENABLED: Enables the menu item to make the item can be selected and restore it from the state of the gray.

MF_GRAYED: Enables the menu item to be ineffective and grayish so it cannot be selected.

MF_MENUBARBREAK: The function of the menu strip with the MF_Menubreak flag. For the drop-down menu, submenu or shortcut menu, the new column and the old column are separated by the vertical line.

MF_MENUBREAK: Place the menu item in the new row (for the menu bar), or normally (for the drop-down menu, submenu or shortcut) and unsenger columns.

MF_OWNERDRAW: Specifies the menu item as the self-drawing menu item. The menu is first displayed, and the window with the menu receives a WM_MEASUREITEM message to get the width and high of the menu item. Then, as long as the menu item is modified, the WM_DRAWITEM message will be sent to the menu owner's window program.

MF_POPUP: The specified menu opens a drop-down menu or submenu. Parameter UidNewltem drop-down menu or submenu handle. This flag is used to give the menu bar, open a drop-down menu, or add a name in the menu item, submenu or shortcut menu.

MF_SEPArator: Draw a horizontal zone. This flag is only used by the drop-down menu, used in the menu or shortcut menu. This district line cannot be grayed, invalid or high. Parameters ipnewltem and uidnewltem are useless.

Mf_string: The specified menu item is a text string; the parameter lpnewltem point to the string.

Mf_unchecked: Do not place the selected tag next to the menu item (default). If the application provides a selection tag bitmap (see SetMenultembitmaps), place the tag bitmap next to the menu item.

The following logo groups cannot be used together:

MF_DISABED, MF_ENABED and MF_G_G_G_Bitmap, MF_String and MF_OWNERDRAW

MF_MENUBARBREAK and MF_MENUBREAK; MF_CHECKED and MF_UNCHECKED

In the Windows CE environment, the parameters of fuflags are not supported using the following signs:

Mf_bitmap; mf_dosable; mf_grayed

MF_GRAYED can be used instead of MF_DISABLED and MFS_GS_GS_GRAYED.

Windows CE 1.0 does not support laminated menus. When using Windows CE 1.0, you cannot insert an MF_POPUP menu into another drop-down menu. WINDOW CE 1.0 does not support the following signs:

MF_POPUP; MF_MENUBREAK; MF_MENUBARBREAKWINDOWS CE 2.0 or later, the above flag is supported, and the laminafter is also supported.

Function prototype: HDWP BegindeferWindowPos (Int nnumwindows);

parameter:

NNumWindows: Indicates the number of initial windows that store location information. If necessary, the DeferWindowPOS function can increase the size of this structure.

Return Value: If the function is successful, return multiple window location structures. If there is insufficient memory when the memory is allocated, the return value is NULL. If you want to get more error messages, call the getLastError function.

Remarks: Multi-window location structure is an internal structure, and the application cannot be directly referenced.

The DEFERWINDOWPOS function fills the target location information of one or more windows that will be moved in the multi-window location structure. EnddeferWindowPos receives the handle of this structure and relocates these windows based on the information stored in this structure. If you set the SWP_HIDEWINDOW and SWP_SHOWWINDOW flags in any of the multi-window location structure, all windows cannot be relocated.

If the system must increase the number of initial windows set by NNumWindows in the multi-window location structure, but there is not enough memory allocation, the entire window relocation order of the system failed (BeGindewsPos, EnddeferWindowPOS). The application can perform early detection and processing during the execution by specifying the maximum number required.

Quick check: Windows NT: 3.1 or above; Windows: 95 or above; Windows CE: Does not support: header file: Winuser.h; library file: user32.lib.

"No Yes YES52 Beginpaint Prepares a Drawing Window YES YES YES53 BeginPath Starting a Rating YES YES YES54 BeginUpdateresource In Executable File Update" Function: This function returns a handle that can be used by the Updateresource function to execute Add, delete, or replace resources in the file.

Function prototype: Handle BeginUpdateresource (LPCTSTSTSTSTSTSTEEXISTINGRESOURES);

parameter:

PfileName: Points to an empty string pointer indicating the end of it is used to specify the file name based on 32-bit executable files based on the resource. The application must obtain the ability to access this file and this file cannot be executed in the current state. If the PFileName is not specified, the system will search for this file under the current path.

BDeleteexistingResources: Description Whether to delete the existing resources specified by the PfileName parameter. If this parameter is true, the existing resource will be deleted, and the update executable includes only resources added by the Updateresource function. If this parameter is false, the updated executable includes existing resources unless deleted or replaced by the Updateresource specifically.

Return Value: If this function is running success, its value will return a handle by using the Updateresource and the EndUpdateresource function. If the specified file is not an executable file, or the executable file has been loaded, or the file does not exist, or the file cannot be turned on, the return value is empty. If you want to get more error messages, call the getLastError function.

Quick check: Windows 3.1 or more. Header file: WinBase.h: library file: kernel32.lib, Unicode: Double version of Unicode and ANSI on Windows NT.

"No Yes Yes55 Bitblt In Device Description Space Copy Bitmap Yes Yes Yes56 BringWindOPTOP Set the specified window to the top of the z-order" function feature to set the specified window to the top of the z. If the window is a top window, the window is activated; if the window is for the window, the corresponding top parent window is activated.

Function prototype: B00L BRINGWINDOWTOP (HWND, HWND); parameter:

HWnd: Set the window handle to the top of the z-order.

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.

Note: Use the BringWindowTotop function to display the window that is partially or all of the other windows or all.

Calling this function is similar to calling the SetWindowPos function to change the location of the window in the z order, but the bringwindowtotop function does not make a window a top window.

If the application is not in the front desk and wants to set it in the front desk, you can call the setForegroundWindow function.

Quick check: Windows NT: 3.1 or above; Windows: 95 or above; Windows CE: 1.0 or above; header file: winuser.h; library file: user32.lid.

"YES YES YES57 BROADCASTSYSTEMMESSAGE Send Message to Specifies" function function: This function sends a message to the specified recipient. The recipient can be an application, install the drive, network drive, system-level device driver, or a combination of these system components.

DWFLAGS: Options flag. The combination of the column value can be removed:

BSF_FLUSHDISK: The recipient handles the message after cleaning the disk.

BSF_FORCEIFHUNG: Continue broadcast messages, even if the timeout cycle is over or a recipient has hang.

BSF_IGNORECURRENTTASK: Does not send messages to windows belonging to the current task. In this way, the application will not receive its own message.

BSF_NOHANG: Forced application timeout. If a recipient timeout, no longer continuing to broadcast messages.

BSF_Notimeoutifnothung: As long as the recipient does not hang, wait for the response to the message. There will be no timeout.

BSF_POSTMESSAGE: Send a message. Can't use with BSF_Query.

BSF_QUERY: Each time you send a message to an acceptor, only the current recipient returns TRUE to send to the next recipient.

LPDWRECIPIENTS: Pointer to the variable, which contains information and information of the message recipient. This variable can be a combination of the following value:

BSM_Allcomponents: Broadcast to all system components.

BSM_allDesktops: Windows NT, broadcast to all desktops. Require SE_TCB_NAME privileges.

BSM_Applications: Broadcast to the application.

BSM_INSTALLABEDRIVERS: Windows 95, broadcast to the installation drive.

BSM_INTDRIVER: Windows 95, broadcast to the network drive.

BSM_VXDS: Windows 95 is broadcast to all system-level device drivers.

When the function returns, this variable accepts a combination of the above value to determine the recipient that is really accepting the message. If this parameter is NULL, broadcast the message to all components. UIMESSAGE: System message identifier.

WPARAM: 32 bit message specific value.

IParam: 32 bit message specific value.

Return value: If the function call is successful, the return value is a positive number. If the function cannot broadcast the message, the return value is C1. If the parameter dwflags is BSF_QUERY and at least one recipient returns Broadcast_Query_deny to the corresponding message, the return value is zero.

Function prototype: LResult CallWindowProc (WndProc LppRevwndfunc, HWND HWND.UINT MSG, WPARAM WPARAM, LPARAMIPARAM);

parameter:

LPPREVWNDFUNC: The pointer to the forward window process. If the value is obtained by calling the getWindowlong function, and the NLndex parameter in the function is set to GWL_WNDPROC or DWL_DLGPROC, then it is actually the address of the window or dialog, or the handle represents the address.

HWnd: Points the handle of the window process for receiving the message.

MSG: Specifies the message type.

WPARAM: Specify the rest, message-specific information. The content of this parameter is related to the MSG parameter value.

IParam: Specifies the rest, message-specific information. The content of this parameter is related to the MSG parameter value.

Return Value: The return value specifies the message processing result, which is related to the message sent.

Remarks: Use the function CallWindowsProc to make a window subclassification. In general, all windows of the same class share a window process. Subclasses are a set of windows of a window or the same class, and these messages are interpreted and processed by another window process before their message is transmitted to the window process.

The SETWINDOWLOOG function makes the system call the new window process by changing the window process related to the specific window, and the new window process replaces the previous window process. The application must transfer any messages that have not been processed by calling CallWindowsProc to the previous window procedure, which allows the application to create a series of window processes.

If strict is defined, the LPPREvWndFunc parameter has a WndProc data type. The WndProc type describes the following: LRESULT (Callback · WndProc) (HWND, UINT WPARAM, LPARAM)

If strict is not defined, the LPPREvWndFunc parameter has a FarProc data type. The FarProc type description is as follows: int (FAR WINAPL · FARPROC) ()

In the C language, FarProc stated that it is a callback function that does not specify a parameter table. However, in C ; the empty parameters in the statement indicate that the function does not have a parameter. This subtle difference is possible to cause a code error. Here is a solution: #ifdef strict; wndproc mywindowprocedure; #else; farproc myindowprocedure; #ENDIF IRESULT = CallWindowProc (MyWindowProcedure, ...)

Further information about the empty parameter table of this function, refer to the C programming language written in Bjarne Stroustrus, written 2nd Edition.

For the Windows NT: Function CallWindowsProc Function, UNICODE to ANSF conversion processing. If you call the window directly, you cannot take advantage of this conversion.

Insert the marker shape. Can be a line, block, or bitmap. Function prototype: Bool CreateCaret (HWND HWND, HBIBMAP HBITMAP, INT NHEIGHT);

parameter:

HWnd: Specifies the commission with a window that is inserted.

HBitmap: Identifies a bitmap for defining the shape of the inserted marker. If the parameter is null, the insert mark is solid (primary color), if the parameter is (hbitmap) 1, then the insert mark is gray. If this parameter is a bitmap sector, the insert mark is the specified bitmap. Bitchart Squi must have been created by createBitmap, CreatorDibitmap or LoadBitmap function.

If hbitmap is a bitmap, then the CreateCaret function will ignore the parameters NWIDTH and NHEIGHT because the bitmap defines its width and height.

NWIDTH: Specify the width of the insert mark according to the logical unit, if the parameter is zero, then the width is set to the window boundary width defined by the system. If hbitmap is a bitmap sector, the function CreateCaret ignores the parameter.

NHEIGHT: Specifies the height of the insert mark as a logical unit. If this parameter is zero, then the window boundary of the system-defined window is high if hbitmap is a bitmap section, then the function CreateCaret ignores the parameter.

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

Remarks: Parameters NWIDTH and NHEIGHT specify the width and height of the inserted tag, which is represented by logical unit; according to the true width and height of the pixel.

The CREATECARET function automatically clears the previous inserted mark, and does not consider ownership the inserted tag. The newly created insert tag has been hidden until the application calls showcaret function makes the insertion tag.

The system provides an insert mark for each queue. The window only creates an insert mark when it has a keyboard focus (FOCUS) or it is an active window. This window should clear the insert mark before the keyboard focus disappears or window becomes inactive.

You can retrieve the width or height of the system window boundary by using the GetSystemMetrics function and specifying the SM_CXBORDER and SM_CYBORDER value. The width or height of the window boundary can ensure that the insert mark is visible on the high resolution screen.

For Windows CE: Windows CE does not support HbitMap parameters, and this parameter should be set to NULL. Windows CE default is solid (Solid) insert tag.

The dialog template consists of the title of the description dialog, followed by the title to describe one or more data blocks of each control, the template can be used in standard format or extended format.

In the standard template, the title is composed of a DLGTEMPLATE structure follows one bearing length array. Each control data is composed of a DLGTEMPLATE structure with a bearing length array.

In the extended template, the title is in the DLGTemplateEx format and control defines the DLGITEMPLATEEX format.

After the CreatedIlogindirectParam function returns, the template can be released, this template is only used to start the dialog.

HWndParent: Identify the window with the dialog.

Ipdialogfunc: Point points to the dialog process, for more dialog, see DialogProc.

LParamlnit: Specifies the value in the iParam parameter passed to the WM_INIDIALOG message.

Return Value: If the function call is successful, the return value is the handle of the point to the dialog: if the function call fails, the return value is NULL. To get more error messages, you can call the getLastError function.

Remarks: The CreatDialogindirectParam function uses the CreateWindowEx function to create a dialog, then send a WM_INTDIALOG message to the dialog application if the template specifies the DS_SETFONT type, the function also sends a WM_SETFont message to the dialog application. If the template specifies the WS_Visble type, the function is displayed, and final MedialogDirectParam returns the window handle pointing to the dialog.

After the CreatDialogindirectParam function returns, use the showWindow function to display the dialog (if not yet displayed). Use the DESTROYWINDOW function to clear the dialog.

In the Standard Dialog Template, the DLGTemplate structure and each DLGItemTemplate structure must be aligned in DWORD borders, and the data created by the DLGEMTEPLATE structure must also be aligned according to DWORD boundaries. All other variable length arrays in the template must be adjusted according to the DWORD boundary.

On the extended dialog template, the DLGTemplateEx structure and each DLGITEMTEMPLATEEX structure must be aligned by DWORD border, and the data arranging the DLGEMTEPLATE structure must also be aligned according to DWORD boundaries. All other variable length arrays in the template must be adjusted according to the DWORD boundary.

All dialog templates of the string, such as the title of the dialog, buttons, must be a Unicode string. use

MultibyToWideChar function Generates these Unicode strings to create code that works on both Windows and Windows NTs.

Windows 95 and later: The system can support up to 255 controls each dialog template. To put more than 255 controls into the dialog box, you can create controls in the WM_INITDLALOG message processor instead of putting them into the template.

Windows CE: Dialogs outside the visual screen area cannot be automatically repositioned. If the user presses Alt H while the dialog box is input, the system transmits a WM_HELP message to the dialog process, and the application should respond to this message via the display dialog descriptor.

The type member of the DLGTemplate structure does not support the following types:

DS_SETFONT: The font cannot be set in the dialog.

DS_RECURSE: No need. Any sub-dialog is automatically seen as a recursive dialog.

DS_CONTROL: No need.

Creating a custom application application for custom dialogs, often using defdlgproc instead of a DEFWINDOWPROC function to perform default messages. The application creates a custom dialog class by popping a WNCLASS structure with appropriate information and creating a custom dialog class by using a class that registers with the RegisterClass function. Some applications use the getClasslnfo function to specify the name of the definition dialog box to populate this institution. In this case, the application changes at least the number of IPSZClassNameDe before registration. In all cases, the CBWndextra member for the custom dialog must be set to DLGWINDOWEXTRA for the custom dialog. The DEFDLGPROC function must not be called through a dialog application, which will result in loop execution.

The EnddeferWindowPOS function uses information in this structure to change the location and size of some windows at the same time. This structure is created by the BegindeferWindowPOS function.

Function prototype: HWND DeferWindowPos (HDWP HWInPoslnfo, HWND HWND, HWND HWNDLNSERTAFFER, INT X, INT Y, INT CX, INT CY, Unit Ufags);

parameter:

HWINPOSLNFO: Handle of multi-window positioning structure, the structure contains the size and positioning information of one or more windows, which can be returned by the function BeGinderWindowPOS or returned by the DEFERWINDOS function that is the last call.

HWND: The handle of the window, the update information of the window is stored in the structure.

HWndlnsertAfter: The handle of the front window of the z preface to the positioned window. This parameter must be one of the window handle or the following: hwnd_bottom: Position the window at the bottom of the z. If the HWnd parameter specifies a top-level window, the window will lose the top position and is ranked at the bottom of all other windows.

HWND_NOTOPMOST: Place the window at the top of all top-level windows (ie, behind all top windows). This parameter does not work if the window is already a non-top window.

HWND_TOP: Place the window at the top of the z order.

HWND_TOPMOST: Place the window at the top of all non-top windows, even if it is not activated, the window remains a top position. This parameter will be ignored if the SWP_NOZORDER flag is specified in the uflags parameter.

x: Specify the X coordinates in the upper left corner of the window.

Y: Specifies the Y coordinate of the upper left corner of the window.

CX: The new width of the window is defined in pixels.

CY: The new width of the window is defined in pixel. ULAGE: Specifies a combination of the values that affect the size and location of the window:

SWP_DRAWFRAME: Draw a border around the window (this border is defined in the window class).

SWP_FRAMECHANGED: Send a WM_NCCAlCSize message to the window, even if the size of the window is not changed, it is also necessary. If this flag is not specified, only the wm_nccalcsize message is sent when the window size changes.

SWP_HIDEWINDOW: Hide the window.

SWP_NOACTIVATE: Do not activate the window. If this flag is not specified, the window is activated and moved to or at the top of the top window or the top of the top window according to the setting of the HWndLnsertAfter parameter.

SWP_Nomove; maintain the current location (ignore the X and Y parameters).

SWP_NOOWNERZORDER: Does not change the location of the owner window in the z order.

SWP_NOREDRAM: No window updates. If this flag is set, no window is refreshed. Includes not to refresh the client area, non-client zone, including the title bar and scroll bar, and some parent windows exposed due to window movement. When this flag is set, the application must explicitly indicate any part of the original window and redraw the window and the parent window needs to redraw some.

SWP_NOREPSITION: With the SWP_Noownerzorder flag.

SWP_NOSENDCHANGING: Prevent window accepts WM_WindowPoschanging messages.

SWP_NOSIZE; keep the current size. (Ie Ignore the CX, XY parameters).

SWP_NOZORDER: Keep the current z order (ignore the hwndlnsertAfter parameter).

SWP_SHOWWINDOW: Displays the window.

Return Value: The return value indicates the updated multi-window positioning structure. The handle returned by the function may be different from the handle passed to the function. The new handle returned by this function should be passed to the DeferWindowPos function and the EnddeferWindowPos function when the next call is called. If the system resources are insufficient when the function is called, the function returns NULL. To get more error messages, call the getLastError function.

Note: If the call function deferWindowPos fails, the application should discard the window positioning action and no longer call the EnddeferWindowPos function. If you do not specify SWP_NOZORDER, the system will be positioned by the window specified by the HWND parameter to the window after the window specified at the HWndlnsertAfer parameter. If the HWndLnsertafsr parameter is empty or hWND_TOP, the system places the window in the top of the z-order. If hwndlnsertafer is set to hwnd_bottom, the system places the window in the bottom of the z order.

The coordinates of all sub-windows are coordinates with respect to the upper left corner of the parent window client area.

One window can be set to top windows in two ways: or HWndlNsertafter is HWND_TOPMOST and ensure that the SWP_NOZORDER flag is not set; or the location of the window in the z-order makes it at the top of all existing top windows. When a non-top window is set to the top window, it belongs to its window to be set to the top window, and the owner does not change.

If SWP_NOACTIVATE or SWP_NOZORDER is not set (ie, when the application requires that it is activated while changing its Z preface), the HWDFNSERTPOS parameter is only used in the following cases:

In the HWndlnsertAfter parameter, there is neither hWnd_topmost nor setting hwnd_nottopmost flags; the window specified by hwnd is not a activation window;

The application should set the window to the top of the z-order when setting the window to the active window. The application can change the location of the activated window in the z-order, or move the window to the top window or the non-top window after activating a window. If a top window is relocated to the bottom of the z-order (hWnd_bottom) or any non-top window, it will no longer be the top window.

A non-top window may have a top window, which is not true. Any window (eg, a dialog box) is set to the top window to ensure that all the slave windows are on the owner.
