Bug in TerminateProcess() and/or GetWndTask() function(s) ?
Posted: Sat Nov 29, 2008 09:24 PM

I'm trying to close a FiveWin application (caption = 6.0) from another but it's not working.

TerminateProcess( GetWndTask( FindWindow ( , "6.0" ) ), 1 )
OR
hWnd := FindWindow(, "6.0" ) <--- this gets the correct window handle
hTask := GetWndTask( hWnd ) <--- this fails, getting the wrong number

Isn't GetWndTask( hWnd) supposed to get the process id ?

TerminateProcess( hTask , 1 ) <--- this fails because of the wrong hTask

Any clues ?

Gustavo,

Here you have a working example, implemented in a different way:

Code: Select all Collapse

#include "FiveWin.ch" 

function Main() 

   local oDlg

   DEFINE DIALOG oDlg TITLE "Test" 

   @ 1, 1 BUTTON "Calculator" OF oDlg SIZE 50, 13 ACTION WinExec( "calc" )
   
   @ 1, 12 BUTTON "Close" OF oDlg ;
      ACTION SendMessage( FindWindow( 0, "Calculator" ), WM_CLOSE )

   ACTIVATE DIALOG oDlg CENTERED 

return nil

regards, saludos

Antonio:

This: hWnd := FindWindow( "6.0" ) returns 0

This: hWnd := FindWindow(, "6.0" ) returns 265412

Now, this: MsgInfo( GetWndTask( hWnd ) ) returns 3760 that does not shows up in Windows' Task Manager's Processes.

Thank you for your help.
