LoadCursor (Windows Embedded CE 6.0)

This function loads a cursor resource.

Syntax

HCURSOR LoadCursor( 
  HINSTANCE hInstance, 
  LPCTSTR lpCursorName
);

Parameters

  • hInstance
    [in] Handle to an instance of the module whose executable file contains the cursor to be loaded.

  • lpCursorName
    [in] Long pointer to a null-terminated string that contains the name of the cursor resource to be loaded. Alternatively, this parameter can consist of the resource identifier in the low-order word and zero in the high-order word. The MAKEINTRESOURCE macro can also be used to create this value.

    To use one of the Microsoft Win32 predefined cursors, the application must set the hInstance parameter to NULL and the lpCursorName parameter to a specific value. The following table shows the possible values. This parameter must be set to one of these values.

    Value Description

    IDC_APPSTARTING

    Standard arrow and small hourglass.

    IDC_ARROW

    Standard arrow.

    IDC_CROSS

    Crosshair.

    IDC_HAND

    Hand.

    IDC_HELP

    Arrow and question mark.

    IDC_ICON

    Obsolete.

    IDC_NO

    Slashed circle.

    IDC_SIZE

    Obsolete; use IDC_SIZEALL.

    IDC_SIZEALL

    Four-pointed arrow pointing north, south, east, and west.

    IDC_SIZENESW

    Double-pointed arrow pointing northeast and southwest.

    IDC_SIZENS

    Double-pointed arrow pointing north and south.

    IDC_SIZENWSE

    Double-pointed arrow pointing northwest and southeast.

    IDC_SIZEWE

    Double-pointed arrow pointing west and east.

    IDC_UPARROW

    Vertical arrow.

    IDC_WAIT

    Hourglass.

Return Value

The handle to the newly loaded cursor indicates success. NULL indicates failure. To get extended error information, call GetLastError.

Remarks

This function loads the cursor resource only if it has not been loaded; otherwise, it retrieves the handle to the existing resource. This function returns a valid cursor handle only if the lpCursorName parameter points to a cursor resource. If lpCursorName points to any type of resource other than a cursor (such as an icon), the return value is not NULL, even though it is not a valid cursor handle.

This function searches the cursor resource most appropriate for the cursor for the current display device. The cursor resource can be a color or monochrome bitmap.

Use the cursor component when targeting a platform that does not support mouse cursors. The only cursor this component supports is the wait cursor (IDC_WAIT). Use the LoadCursor function in conjunction with the SetCursor function to set the wait cursor.

SetCursor(LoadCursor(NULL, IDC_WAIT));

Use the mcursor component when targeting a platform that does support mouse cursors. This component supports the LoadCursor function the same way Windows desktop platforms do, except that it only supports monochrome cursors. Windows Embedded CE does not support color cursors. An attempt to load a color cursor will have unpredictable results.

Requirements
