Handle of the Window to be used. |

Remarks |
The WINDOW statement may be used with any type of window in your program, including a Control or Dialog. Generally speaking, the window to be manipulated or tested is identified by its handle (hWin), which is often obtained at the time it is created. However, since a control is usually accessed by a "Parent / ID" combination, you must use CONTROL HANDLE to retrieve its handle for this purpose. WINDOW GET ID hWin TO datav& The integer ID of the window hWin is retrieved and assigned to the variable designated by datav&. Generally, only a CONTROL will have an ID, so windows of other classes will normally return the value zero. WINDOW GET PARENT hWin TO datav& The handle of the PARENT is retrieved and assigned to the variable designated by datav&. |
