I write a program in which I create 2 edit boxes, 2 lists and 2 buttons inside the window - see text below. Program works but when I press tab button to pass from one window to another operation fails. Why?
Thanks, Mike

If you want the "dialog box" navigate functions you must call IsDialogMessage in your message loop (yes, even if your window isn't a dialog box)

And here is an example of a message loop.

Message loop



.while TRUE

    invoke GetMessage,addr msg,NULL,0,0

  .BREAK .if !eax

    invoke IsDialogMessage,hWnd,addr msg

    .if !eax

      invoke TranslateMessage,addr msg

      invoke DispatchMessage,addr msg

  .endif

.endw

and don't forget to set the WS_TABSTOP windows-style...

oh and you don't have to call translatemsg & dispatchmsg...
isdialogmessage translates and dispatches keyboard msg's
alone, too...



_Start: invoke  GetMessage,ADDR msg,NULL,0,0 

        test    eax, eax

        jz      _Exit

        invoke  IsDialogMessage,hWnd,addr msg

        jmp     _Start

_Exit:  mov     eax,msg.wParam

        ret



...and later...



        invoke CreateWindowEx, NULL, ADDR ButtonClassName,ADDR Button1Text,\

            WS_CHILD or WS_VISIBLE or WS_TABSTOP or BS_DEFPUSHBUTTON,\

            430,30,100,25,hWin,Button1ID,hInstance,NULL
