The framework calls this member function by a minimized (iconic) window that does not have an icon defined for its class.

afx_msg HCURSOR OnQueryDragIcon( );

A doubleword value that contains a cursor or icon handle in the low-order word. The cursor or icon must be compatible with the display driver's resolution. If the application returns NULL, the system displays the default cursor. The default return value is NULL.

The system makes this call to obtain the cursor to display while the user drags the minimized window. If an application returns the handle of an icon or cursor, the system converts it to black-and-white. If an application returns a handle, the handle must identify a monochrome cursor or icon compatible with the display driver's resolution. The application can call the CWinApp::LoadCursor or CWinApp::LoadIcon member functions to load a cursor or icon from the resources in its executable file and to obtain this handle.
