Hi all,

I have a very basic application which has just a dialog with a listbox
on it. I need to simulate in the listbox the ctrl+a and ctrl+c
behavior. I mean, in the listbox there are some lines (messages sent
by another application) and I would like to do like any windows user
is used: ctrl+a to select the whole content of the listbox, then
ctrl+c to copy everything in the clipboard.

The code I'm having at the moment:

<myfile.rc>

// Microsoft Visual C++ generated resource script.
//
#include "resource."

#define APSTUDIO_READONLY_SYMBOLS
/////////////////////////////////////////////////////////////////////////////
//
// Generated from the TEXTINCLUDE 2 resource.
//
#include "afxres.h"

END

Can smbd point me how could I have the ctrl+a, ctrl+c behaviour
implemented into this listbox?

Thanks in advance,
Viv

Hi Viv,

you could subclass your listbox to get the ctrl+a, ctrl+c key messages.
Search MSDN for "subclassing". MS changes and removes contents all the
time.

On ctrl+a -> LB_SETSEL with wParam = (WPARAM)TRUE and lParam = (LPARAM)-1.

On ctrl+c -> OpenClipboard, EmptyClipboard, SetClipboardData,
CloseClipboard.

Regards,
Friedel
