"YES YES YES302 EndDialog Hide Dialog" function function: This function clears a modal dialog and causes the system to abort any processing of the dialog.

Function prototype: BOOL EndDialog (HWND HDLG, INT NRESULT);

parameter:

HDLG: Indicates the dialog window to be cleared.

NResult: Specifies the value that returns from the creation dialog function to the application.

Return value: If the function call is successful, the return value is a non-zero value; if the function call fails, the return value is zero. If you want to get an error message, please call the getLastError function.

Note: Dialog Boxes created by Dialogbox, DialogBoxParam, DialogboxlndirectParam Functions must be cleared with the EndDialog function. The application is called from the dialog application to call the EndDialog function, which cannot be used for other purposes. The dialog application can call the EndDialog function at any time; even during the WM_INITDIALOG message processing. If the application calls this function during the WM_INTDIALOG message processing, the dialog is cleared before the display and input focus are set. The EndDialog function does not immediately clear the dialog. Instead, set a flag and allow the dialog application to return the control back to the system. The system detects the logo before trying to search the next message from the application queue. If the flag has been set, the system abort message loop, clear the dialog, and use the value in the NRESULT as the value returned from the creation dialog.

Function prototype: HRSRC FindResource (HModule Hmodule, LPCTSTR LPNAME, LPCTSTSTR LPTYPE);

parameter:

HModule: Processes the module of the executable of the resource. NULL values ​​The specified module handle points to the operating system to create a related bitmap file for the recent process.

LPNAME: Specifies the name of the resource. For more information, see the Note section.

LPTYPE: Specifies the resource type. For more information, see the Note section. As a standard resource type. The meaning of this parameter is with EnumreslangProc / LPTYPE.

Return Value: If the function is running success, the return value is the handle pointing to the specified resource information block. In order to obtain these resources, pass this handle to the loadResource function. If the function is running, the return value is NULL. To get more error messages, call the getLastError function.

Note: If the high byte of the parameter LPTYPE or LPNAME is O, the type or name identity of the resource given in the low byte will be described. In addition, these parameters points to a string of null as a terminator. The first character of the string is #, the following characters indicate the decimal number to indicate the integer identifier of the source type or name. E.g. String "# 258" indicates an integer identifier 258. If you submit a resource with an integer identifier, you will reduce the required memory capacity.

When using the accelerator table, bitmap, cursor, icon, or menu, you can release memory by calling the functions listed in the following table. Accelerator table: DestroyAcceleratorTable; Bitmap: deleteObject; cursor: destroycursor; icon: destroylcon; menu destroymenu.

When the process creates a resource termination, the system will automatically delete these resources. However, by calling the appropriate function, the memory can be retained, and the space required to be required during the process is reduced.

Applications can use the FindResource function to find any kind of resources, but this function is only used when the application is sent and sent to the LOADLIBRAY and LOCKResource functions.

If you want to use a resource immediately, the application will use a function in the list of detailed resource functions to find the load required for the required resources, formatmessage: Machilization and formatted information table interface: loadaccclerators: load accelerator table; loadbltmap: Load bitmap Resources; loadcursor: loading cursor resources; loadlcon: Load icon resources;

LoadMenu: Load menu resource; loadstring: Load string table resources.

For example, an application can load an icon using the loadlcon function to display on the screen. However, if it is loaded with an icon to copy its data to another application, then this application should use the FindResource and LoadResource functions.

String resources are stored in a certain area consisting of several parts, with 16 strings per part. Each part of the string is stored in an orderly team arranged in a unified count.

The TheloadString function will pick string resources from the corresponding area.

Parameters hmodule cannot be a NULL handle.

The parameter lpname does not support the resources of IDs, which cannot work as expected by expectations, that is, FindResource (H, O, T).

It is impossible to pass the RT_anicursor or RT_anllcon value in the iptype parameter.

Function prototype: Short getaynckeyState (int vkey); parameter:

Vkey: Defines virtual keys (if there are 256 virtual keys). For more information, see Virtual_Key Codes. In Windows NT, you can use the left and right keys to define some keys. For more information, refer to the Remark section.

Return Value: If the function call is successful, the return value gives the last call getasyncKeyStat. Since, whether the specified key is in a statement, and it is determined that the key is currently pressing or being bounted. If the highest bit is set to 1, the key is taken below: If the lowest bit is set to 1, the key is in the next state in the previous calling GetAsyncKeyState. If another process or the window in the thread has a keyboard focus,

The return value is zero.

Windows 95: Windows 95 does not support left-right key distinction, if you call the getasyncKeyState function with these constants, the return value is zero.

Remarks: This function supports the mouse button, but it is not a status of the logic button mapped to the physical button, and the status of the actual physical button. For example, the function call getasynckeyState (vk_lbutton) always returns the state of the physical mouse left button, regardless of the button map to logically left buttons, you can call GetSystemMetrics to determine the corresponding physical mouse button and the logical mouse button corresponding to the system. Relationship, when the mouse button is swapped left and right, the function returns True.

You can use the virtual key code constant VD_SHIFT, VK_CONTROL, VK_MENU as the value of the Vkey parameter, which gives the SHIFT CTRL, the AIT key, and does not distinguish the left button or the right button.

Windows NT: You can use the following virtual key code constants as the value of Vkey to distinguish the left right key:

VK_LSHIFT VK_RSHIFT; VW_LCONTROL VK_RCONTROL; VK_LMENU VK_RMENU

These distinguishable left and right constants are only available when the GetKeyboardState, SetKeyboardState, GetSyncKeyState, GetKeyState, and MapViruaiKey functions are available.

Windows CE: The getasynckeyState function supports left and right virtual key constants, so the definition is pressed or right. These constants are VKLSHIFT, VK_RSHIFT, VK_LCONTROL, VK_RCONTROL, VK_LMENU, and VK_RMENU.

The lowest bit of the return value in Windowsce is invalid and should be ignored.

GetasyncKeyState will return the status of the current key, even if another process or the window in the thread has a keyboard focus.

You can use the VK_LBUTTON virtual keycase constant to determine the state of the tip of the touch screen (press / bounce up).

For dialogs that use system fonts, you can use these values ​​between dialog templates, such as between dialog templates and pixels. For dialogs that do not use the system font, from the dialog template unit to the pixel conversion to be determined according to the font used in the dialog. One type of the dialog is easy to perform conversion with the MapDialogRect function, MapDialogRect considers the font and corrects a rectangular template unit to this pixel.

Function prototype: Long getDialogbaseunits (void);

Parameters: None.

Return Value: The return value is a value of a 32-bit containing a dialogature unit. The low word of the return value contains the basic unit of the horizontal dialog, and the high low level contains the basic unit of the vertical dialog.

Remarks: The horizontal basic unit returned by the getDialogbaseunits function is equal to the average width of the system font. The vertical base unit is equal to the average height of the character in the system font; for a dialog box without using the system font; The basic unit is equal to the average width and average height of the pixel. These values ​​can be calculated using the GetTextMetrics and GetTextExtentPoint32 functions to be used as a selected font. However, if the calculation results are different from those performed through the system, then the MapDialogRect function can be used to avoid possible errors. Each horizontal basic unit is equal to four horizontal dialog template units; each vertical base unit is equal to eight vertical dialog template units. So use the following formula to convert the dialog template unit into pixels: piselx = (TemptateUnitX * BaseUnitX) / 4; piseiy = (TemplateUnity * BaseUnity) / 8

Similarly. Use the following formula to convert pixel to dialog box template unit: templateunitX = (Pixelx * 4) / baseUnitX; templateunity = (PLXELY * 8) / BaseUnity

"YES YES YES539 GetKeyState Returns the Status" function function: This function checks the status of the specified virtual key. This state specifies that this button is a UP state, and the DOWN state is still triggered (switches when the switch is pressed each time the key).

Function prototype: Short getKeyState (int nvirtkey);

function:

NVRTKey: Defines a virtual key. If the required virtual key is a letter or number (A ~ Z, A ~ Z or 0 ~ 9), NVIRTKEY must be set to the corresponding character ASCII code value, for other keys, NVIRTKEY must be a virtual key code. If a non-English keyboard layout is used, the value of the virtual key of ASCIIA to Z and 0 to 9 is used to define most of the character keys. For example, for the German keyboard format, the virtual key of the value ASCII0 (OX4F) refers to "" 0 "" button, and VK_OEM_1 refers to "" 0 key with vagado ""

Return Value: The return value gives a status of a given virtual key, and the status is as follows:

If the high sequence is 1, the key is in the DOWN state, otherwise it is a UP status.

If the low sequence is 1, the key is triggered. For example, the Caps Lock button is found, it will be triggered. If the low sequence position is 0, the key is turned off and is not triggered. The indicator of the trigger button on the keyboard, when the key is triggered, the key is not triggered when it is triggered.

Note: When a given thread reads the key message from its message queue, the key state returned by the function changes. This state well does not reflect the state of the interrupt level associated with the hardware. Use SetKeyboardState to get this information. To detect all virtual key status information, you can use the setkeyboardState function.

The application can use virtual keycase constants vk_shift, vk_control, and vk_menu as the value of the NVIRTKEY parameter. It gives the value of Shift, Ctrl or Alt key, without distinguishing between the left and right keys, the application can also use the following virtual key code constant as the value of the NVIRTKEY to distinguish the left button, right-click.

VK_LSHIFT, VK_RSHIFT; VK_LCONTROL, VK_RCONTROL; VK_LMENU, VK_RMENU

These distinguishes are only available for constants that are not available when the application calls getKeyboardSlate, SetKeyboardState, GetAsyncKeyState; GetKeyState, and MapVirtualKey functions.

Windows CE: The getKeyState function can only be used to check the Down status of the following virtual key.

VK_Lshift, vkrshift, vk_lcontrol; vk_rcontrol; vk_lmenu, vk_rmenu

Return Value: If the function call is successful, the 0 value is returned. If the function call is unsuccessful, the return value is 0. To get more error messages, you can call the getLastError function.

Note: The application can call this function to check the current status of all virtual keys. When the keyboard message is removed from the message queue of the thread, the state of the virtual key changes. When the keyboard message is sent to the message queue of the thread, or when the keyboard message is sent to the message queue of the other thread or the status of the virtual key does not change when it is detected from the message queue from other threads. (Exception: Sharing the same keyboard status through the thread connected to AttachThreadInput.) When the function returns, each array member points to each array member points to each array member is included in the status data of a virtual key. If the highest bit is set to 1, the key is in the DOWN state; otherwise, the key is in the UP state. If the lowest bit is set to 1, the button is triggered. When a button is opened, it is called triggered, such as a CapSlock key. If the minimum bit is set to 0, the key is turned off and is not triggered. A trigger key is also the indicator (if any) on the keyboard (if any) is lit when the button is triggered, and it is destroyed when it is not triggered. To check the status information of a single virtual key, you can call the getKeyState function. To check the current state of a virtual key, regardless of whether the corresponding keyboard message is expected to be detected from the message queue, you can use the getasynckevState function. The application can use virtual keycase constants vk_shift, vk_control, and vk_menu as the subscript of the array pointed to by LPKEYSTATE. The state of the SHIFT, CTRL, and Alt keys thus given are not distinguished. The application can also be used as virtual key codes constant as left and right above the key distinction bond index: VK_LSHIFT, VK_RSHIFT, VK_LCONTROL, VK_RCONTROL; VW_LMENU, VW_RMENU only when the application calls the GetKeyboardState; when SetKeyboardState, GetAsycKeystate, GetKeyState and MapVirtualKey function, Use these constants that can distinguish between left and right keys.

You can provide an OFNHOOKPROC hook function for a browser style Open dialog. Set the OFENFILFNAME structure of the Flags member of the OpenFilfname structure to indicate and specify the address of the hook function in the IPFNHOK member, allowing the hook function to take effect.

Windows 95 and Windows NT still support the old-style Open dialog to maintain a user interface consistent with a Windows 3.1 or Windows NT3.51 user interface. Enables the OFNHOOKPROCOLDSTYLE hook function and guarantee the Ofn_Explorer flags that are not set, you can display the old Open dialog.

To display a dialog box that allows users to select a directory instead of a file, call the shbrowseforfolder function.
