I'm trying to trap ALT-key. It works, but I hear a sound. How can I avoid it?

Normal.

Master, see if you haven't connected anything in the windows settings.

Code: Select all  Expand view

// Testing NON-Modal Dialog Boxes - \SAMPLES\TESTDLGN.PRG

#include "fivewin.ch"

Static MainWnd

Function Main()

   DEFINE WINDOW MainWnd FROM 1, 1 TO 22, 75 ;
      TITLE "Test" ;
      MENU BuildMenu() ;
      COLOR "W/B"
     
   ACTIVATE WINDOW MainWnd MAXIMIZED ;
      VALID MsgYesNo( "Want to end ?" )
   
Return NIL

Function BuildMenu()

   local oMenu

   MENU oMenu
      MENUITEM OemToAnsi( "&Try" ) ACTION Try( )

      MENUITEM "E&xit" ACTION MainWnd:End()
   ENDMENU
   
Return oMenu

Function Try()

   Local oDlg

   DEFINE DIALOG oDlg TITLE "Non modal dialog"
   
   @ 2, 2 BUTTON "&End" OF oDlg ACTION oDlg:End( )
   
   /*
   ACTIVATE DIALOG oDlg CENTERED NOWAIT ;
      VALID MsgYesNo( "Want to close it ?" )
   */


   ACTIVATE DIALOG oDlg CENTERED

Return NIL

Yes, as I want to handle the ALT-key combination through bKeyDown not with a menu item.

Enrico, I believe that this characteristic is changed in the configuration of the Operating System.

So, it cannot be disabled programmatically?

Enrico, I will remember that we changed for a similar case
METHOD HandleEvent( nMsg, nWParam, nLParam ) CLASS TControl
case nMsg == WM_SYSCOMMAND
return ::SysCommand( nWParam, nLoWord( nLParam ), nHiWord( nLParam ) )
Best regards,
Otto

I don't want to alter the FWH source code. Anyway, I tried with OVERRIDE command and it didn't work (the program didn't start).

Enrico,

You don't have to modify the source, you can subclass instead.

Subclass TControl? Don't think that class is thought for subclassing.
