Return Value: The high word of the return value indicates the type of current message in the queue. The low word indicates that the last call getQueuesttus, GetMessage or FeekMessBGE, adds the queue and still in the queue.
Remarks: QS_ flag appears in the return value that does not guarantee that the call function getMessage or PeekMessage will return a message later. GetMessSge and PeekMessge Perform some internal filtration will cause the message to be handled internal. Therefore, the return value of getQueuesttus can only be seen as a prompt to call GetMessage or PeekMessage.
QS_AllPostMessage and QS_POStMessage flags are different when cleared. QS_POStMessage is cleared when calling getMessage or PeekMessage, whether it is filtered. QS_AllPostMessage is cleared when calling getMessage or PeekMessage, but the filter message (WMSGFiltermin and WMSGFiltermax are zero). This is very useful for multiple calls of PeekMessage for multiple calls.

Note: GetScrollnfo function Although WM_HScroll and WM_VScroll indicate that the scroll bar position message is provided, only 16-bit data is provided, and the function setscrollnfo and GetScrollnfo provide 32-bit scroll data. Thus, when the application is processed when processing WM_HSCROLL or WM_VSCROLL, the GetScrollNFO function is to be called when the data of the 32-bit scroll bar is obtained. During the WM_HSCROLL or WM_VSCROLL message, in order to obtain a 32-bit rolling box position, you need to call the getScrollNFO function to obtain the scrollInfo value in the structural scrollinfo member Fmask. The function returns the value of the rolling box tracking position indicated in the ScrollInfo member NTrackpos. This will allow it to get its position when the user moves the scrolling cartridge.

BPEVERT: Specifies the action that will be executed. If this parameter is false, getSystemMenu returns the handle of the copy of the current use window menu. This copy is initially the same as the window menu, but can be modified.
If this parameter is true, the GetSystemMenu reset the window menu to the default. If there is a previous window menu, it will be destroyed.
Return Value: If the parameter BREVERT is false, the return value is the handle of the copy of the window menu: if the parameter BREVERT is true, the return value is NULL.
Remarks: Any window that does not use functions getSystemMenu to generate your own window menu copy will accept the standard window menu.
The menu item that the window is originally included has a variety of identifiers, such as SC_Close, SC_Move, and SC_SIZE.
The menu item on the window menu sends a WM_SYSCOMMAND message.
All predefined window menu items have a large number of identifiers greater than oxfooo. If an application adds a command to the window menu, the number of identifiers smaller than oxfoo should be used.
The system automatically grasses the menu item on the standard window menu according to the state. The application implements the selection and meat ash by responding to the WM_INITMENU message sent before any one ordered.
In the Windows CE environment, the system menu is not supported, but GetSyemMenu is implemented in a macro manner to keep and exist compatibility. You can use the macro return menu handle to make the closing box are invalid, just as on the Windows desktop platform. The return value under Windows CE does not have other uses.

IDC_ARROW: Standard Cursor;
IDC_CROSS: Cross cursor.
Return Value: If successful, the return value is a handle of the newly loaded cursor: if it fails, the return value is NULL. To get more error messages, call the getLastError function.
Remarks: The loadCursor function loads only the cursor resources that are not loaded, otherwise it detects the handle of the existing optical adapter. This function returns a valid cursor handle if the IPCursorname parameter points to a cursor resource. If lpcursorname does not point to the cursor, it points to other types of resources (such as icon), the function return value is not null, although it is not a valid cursor handle, the function searches the current display device cursor for the most appropriate cursor resources. The cursor resource can be a color or monochrome bitmap.
Windows Ce: When the target platform does not support the mouse cursor. Use the CURSOR cursor component. The unique cursor supported by the cursor assembly is a waiting cursor (IDC_WAIT). Use the loadcursor function to wait for the cursor with the setcursor function. SetCursor (NULL, IDC_WAIT) When the target platform does not support the mouse cursor, use the Cursor cursor component that supports the loadcursor function in the same manner in the desktop window platform, the only difference is that only monochromatic cursors are supported. Windows CE does not support color cursor. Attempting to load a color cursor will result in an unpredictable result. The return value is uncertain.

Function prototype: handle loading (Hinstance Hinst, LPCTSTSTSTSTSTSTSTSTSTSTSTSTSTSTSTSTSZNAME, UINT UTYPE, INT CXDesired, int Cydesired, UINT FULOAD);
parameter:
HinST: Processing the special case of the loaded image module. To load an OEM image, set this parameter value to O.
LPSZNAME: Processing image loading. If the parameter hinst is non-empty, and the parameter fuload does not include the value of the LR_LoadFromFile, the parameter lpszName is a string that pointing to the image resource that is loaded in the Hinst module, and a string of null as the end of the end.
If the parameter hinst is empty, and the lr_loadfromfile is specified, the low word of this parameter must be loaded OEM image identifier. The OEM image identifier is defined in the WinUser.h header file, and the meaning of the prefix is listed below:
OBM_ OEM: bitmap; OIC_OEM icon; OCR_OEM: Cursor. If the parameter fuload contains the lr_loadfromfile value, the parameter lpszname is the file name containing the image.
UTYPE: Specifies the loaded image type. This parameter can be the following value, its meaning is as follows:
Image_bitmap: loading bitmap; image_cursor: load cursor; image_icon: Load icon.
CxDesired: Specifies the width of the icon or cursor, in pixels. If this parameter is zero and the parameter fuload value is lr_defaultsize, the function sets the width using the SM_CXICON or SM_CXCURSOR system metric value; if this parameter is zero and the value LR_DEFAULTSIZE is not used, the function uses the current resource width.
Cydesired: Specifies the height of the icon or cursor, in pixels. If this parameter is zero and the parameter fuload value is lr_defaultsize, then the function sets the height using the SM_CXICON or SM_CXCURSOR system metric; if this parameter is zero and the value lr_defaultsize is not used, then the function uses the current resource height.
Fuload: Specify the function value according to the following composite value list, the value meanings as follows:
LR_DEFAULTCOLOR: The default flag; it does not make anything. Its meaning is "no lr_monochrome".
Lr_createdibsection: When the parameter utype is specified as image_bitmap, the function returns a Dib partial diagram instead of a compatible bitmap. This flag is very useful when loading a bitmap instead of mapping its color to the display device.
LrDifaultsize: If cxdesired or cydesired is not set to zero, use the system specified by the system to identify the width and high of the cursor or icon. If this parameter is not set and cxdesired or cydesired is set to zero, the function uses the actual resource size. If the resource contains multiple images, the size of the first image is used.
LR_LOADFROMFILE: The image is loaded according to the value of the parameter lpszname. If the tag is not given, the value of LPSZNAME is the resource name.
LW_LOADMAP3DCOLORS: Find the color table of the image and replaces the grayscale of the corresponding 3D color table below.
Color replacement: DK Gray RGB (128, 128, 128) Color_3dshadow; Gray RGB (192, 192, 192) Color_3dFacelt Gray RGB (223, 223, 223) Color_3DLight Lr_LoadTransparent; find one pixel color value in the image and according to color table The default color value of the system replaces the value of its respective interface. All the colors of all pixels that use this interface becomes the default form color of the system. This is only used to apply for a corresponding color table.
If Fuload includes two values of LR_LOADTRANSPARENT and LR_LOADMAP3DCOLORS, LRLOADTRANSPARENT is preferred. However, the color table interface is replaced by Color_3dFace, not Color_Window.
LR_Monochrome: Mount black and white map.
Lr_shared: If the image will be shared multiple times. If the LR_Shared is not set, the next call to the same resource will be loaded again to load this image and return a different handle. Do not use LR_Shared using images of different standard sizes, there may be changes after loading, or loaded from the file.
Windows 95 and Windows 98: The function discovers the first image discovered based on the requested resource name in the cache, regardless of the requested size. LR_VGACOLOR: Using VGA true color.
Return Value: If the function is running success, the return value is the handle of the data of the relevant resource. If the function is running, the return value is NULL. If you want to get more error messages, call the getLastError function.
Note: When you use the resource, you must pass the function to release the accelerator table, bitmap, cursor, icon, and menu. : DestroyMenu
When the process creates termination, the system will automatically delete these resources. However, calling related functions can also retain the space settings of the memory reduction process.
Windows CE: For image_bitmap, parameter cxdesred and cydesred p must be zero. The Windows CE does not support chart jumps or flashes.
The parameter fuload must be (= LR_DEFAULTCOLOR).
If the target platform does not support the mouse cursor, you can specify the value of the SM_CXCURSOR and SM_CYCURSOR in the parameter cxdesred and cydsired, but cannot specify the value of Image_Cursor in the parameter utype.
If the target platform supports the mouse cursor, you can specify the value of the SM_CXCURSOR and SM_CYCURSOR in the parameter cxdesired and cydesred, and you can specify the value of Image_cursor in the parameter utype.
