You can use code below to find application window.

#define GW_OWNER 4
#DEFINE GW_HWNDFIRST 0
#DEFINE GW_HWNDNEXT 2

declare integer GetWindowText in win32api integer, string, integer
declare integer GetWindow in win32api integer,INTEGER

foxhwnd = _VFP.hWnd
hwndNext = GetWindow(foxhwnd,GW_HWNDFIRST)
susp
**** loop thru each window to search the title
DO WHILE hwndNext <> 0
	lcBuffer = SPACE(256)
	lnTitle = GetWindowText(hwndNext,@lcBuffer,256)  && get the window text
	IF lnTitle > 0
		lcTitle = LEFT(lcBuffer, lnTitle)
		? lcTitle 
		*** check to see if this is the specified window.
		*....
	ENDIF
	hwndNext = GetWindow(hwndNext,GW_HWNDNEXT)
ENDDO
