Hi Virusim,

>I also interested in maximizing a form. What are the API function to do so in VFP 5.0, please give if possible, please example. Thank a lot

*--------------------------------------------
* The following define statements are from
* WinUser.H
*--------------------------------------------
#define GWL_EXSTYLE         (-20)
#define WS_EX_TOPMOST       0x00000008
#define HWND_TOPMOST    	   (-1)
#define SWP_NOSIZE          0x0001
#define SWP_NOMOVE          0x0002
#define SWP_NOZORDER        0x0004
#define SWP_FRAMECHANGED    0x0020

* Determine the HWND of the form

Local lnHwnd
Declare Integer FindWindow in Win32Api ;
   String lpszClass, ;
   String lpszWindow
lnHwnd = FindWindow(null,"caption of the form")

* Determine the current extended window styles.

Local lnStyle
Declare Integer GetWindowLong in Win32Api ;
   Integer hwnd, ;
   Integer nIndex
lnStyle = GetWindowLong( lnHwnd, GWL_EXSTYLE )

*-----------------------------------------------
* and set the AlwaysOnTop style.

Declare SetWindowLong in Win32APi ;
   Integer hwnd, ;
   Integer nIndex, ;
   Integer lNewLong
lnStyle = BitOr( lnStyle, WS_EX_TOPMOST )
SetWindowLong( lnHwnd, GWL_EXSTYLE, lnStyle )

*-----------------------------------------------
* Redraw the form in order to make the changes
* permanent.
