Env: Windows NT 4.0/SP3, Visual C++ 5.0/SP3.

I'm trying to use a dockable CDialogBar in a SDI application, where the CDialogBar has a control (CStatic derived, Notify property enabled). I have added message handlers for WM_LBUTTONDOWN/WM_LBUTTONUP in the derived CStatic class, but no such messages arrives. How can they be enabled?

The static control sends notifications to its parent when it has been created with the SS_NOTIFY style. Those notifications are:

STN_CLICKED  
STN_DBLCLK  
STN_DISABLE  
STN_ENABLE  
WM_CTLCOLORSTATIC

You can get that notification with OnCommand as stated in the doc for STN_CLICKED, example:

BOOL CYourWnd::OnCommand(WPARAM wParam, LPARAM lParam)
{
    WORD wNotifyCode = HIWORD(wParam); // notification code
    WORD wID = LOWORD(wParam);         // item, control, or accelerator identifier
    HWND hwndCtl = (HWND)lParam;      // handle of control       

    switch( wNotifyCode ) {
    case STN_CLICKED:
        break;
    }

      return CWnd::OnCommand(wParam, lParam);
}

You need to add the message handlers in one of the following classes:
Frame, View, Document or App.

Only these classes get messages from controls on a CDialogBar.

Plaroche, thank you for the answer. I tried it, and it worked as you said it would. Thanks to that I could experiment a little, and I saw that the variable created with ClassWizard was not subclassed properly. When I did that manually, it worked as I wanted in the first place. So even if I'm not using the solution you provided me, it helped to get me to get on the right track.
