The code below successfully finds the window I want it to and sets focus to it but the keyboard command does not work. The same code worked with an open Notepad instance though. I was able to sent '{CTRL-O}' to notepad which brought up the open dialog box. any ideas?

DECLARE INTEGER FindWindow IN user32;
        STRING lpClassName, STRING lpWindowName  
   
  hwnd = FindWindow(.NULL.,[Program Error])
  
  
  DECLARE INTEGER SendMessage IN user32;
    INTEGER hWnd,;
    INTEGER Msg,;
    INTEGER wParam,;
    INTEGER lParam 
    
 DECLARE INTEGER SetForegroundWindow IN user32 INTEGER hwnd
    
    
 if hwnd > 0
	SetForegroundWindow(hwnd)
	keyboard '{ALT-C}'	
 endif
