Hello,
is there a way to "bind" the space-key to a button (without SetWindowsHookEx) so that I can toggle the button with the space key ??
thanks...

BOOL CMyDlg::PreTranslateMessage(MSG* pMsg)
{
    if( pMsg->message == WM_KEYDOWN )
    {
        if( pMsg->wParam == VK_SPACE )
        {
            // do here what you need

            ::TranslateMessage(pMsg);
            ::DispatchMessage(pMsg);
            return TRUE;
        }
    }
      
    return CDialog::PreTranslateMessage(pMsg);
}

You can override PreTranslateMessage and handle the space key there.
You could create an accelerator and use it to generate the same command as the button.

It can be done by creating a push button. Choose check box from the palette and set its style to push button. This will change its state when space is pressed without doing any coding!
