Well the below should work, but nothing gets put in the password window.

DO WHILE CheckWin('Password')
   *--This will display until I close the password window as it should
   WAIT WINDOW "Found the password window" NOWAIT
ENDDO
RETURN

FUNCTION CheckWin
PARAMETER tcTitle

lnwindow = FindWindow(0,tcTitle)
IF lnwindow > 0
   #DEFINE WM_KEYDOWN  0x0100
   DECLARE SHORT SendMessage IN user32; 
       INTEGER   hWnd,; 
       INTEGER   Msg,; 
       STRING  @ wParam,; 
       INTEGER   lParam 

    hwnd = lnwindow
    cmessage = 'password'+CHR(13)
    ReturnValue = SendMessage(hwnd, WM_KEYDOWN, @cmessage, 0)
    RETURN .T.
ELSE
    RETURN .F.
ENDIF

Yet if I run that loop the wait window displays nonstop (as it should) until I close the password window. Once I do that, it exits the loop because lnwindow returns false. So everything is working EXCEPT sending the keystrokes to taht password window... Sheesh, you'd think it was Friday! :o()
