Hi All,

I have to use Sendmessage Winapi and receive message from opposite application. I found this code from internet:

Declare Long FindWindowA In Win32API String cNULL, String cWinName
DECLARE LONG SendMessage IN user32 AS WinAPI_SendMessage ; 
	LONG,; 
	LONG,; 
	LONG,; 
	STRING @
sTitle = "kl_ecrsunucu"
iHwnd = FindWindowA(0, sTitle)
#DEFINE WM_COPYDATA 	0x004A
*  _vfp.hWnd
xstr="qqq"
lnRetVal = WinAPI_SendMessage(ihWnd, WM_COPYDATA, this.HWnd , @xstr)
WAIT WINDOW lnretval 

opposite application look for kl_ecrclient caption at my form. What I should do for receive message after change my forms caption? How can I read message from opposite?
