I have created a toolbar,a font combobox and font-size combobox placed in it,then I place this toolbar into a dialog,when I show this dialog,the problem appeared:

the selection change of font and font-size combobox no effect to my CRichEditCtrl.certainly,I have placed notify receiver that receive notify send from font and font-size combobox,BUT I have founded the notify receiver never called by dialog.Ok,then I read the source code of commandbar,I find this two combobox send it's notify to AfxGetMainWnd() finally,and not it's direct parent/owner(this dialog),SO,I can't receive notify from toolbar's combobox.

Who can give me some suggestions to solve this problem? thanks.

Add to your dialog (code from  CXTPFrameWndBase)

virtual BOOL OnWndMsg(UINT message, WPARAM wParam, LPARAM lParam, LRESULT* pResult)
 {
  if (message == WM_XTP_COMMAND)
  {
   LRESULT lResult = FALSE;
   NMHDR* pNMHDR = (NMHDR*)lParam;

   UINT nID = (UINT)pNMHDR->idFrom;
   int nCode = pNMHDR->code;

   AFX_NOTIFY notify;
   notify.pResult = &lResult;
   notify.pNMHDR = pNMHDR;
   if (OnCmdMsg(nID, MAKELONG(nCode, WM_NOTIFY), &notify, NULL))
   {
    *pResult = lResult;
    return TRUE;
   }
   return FALSE;
  }

  return TBase::OnWndMsg(message, wParam, lParam, pResult);
 }

thank you very much,this problem I have solved by following method:

1. add message entry ON_MESSAGE(WM_XTP_COMMAND,OnXTPMsg)

2.  LRESULT CMyDialog::OnXTPMsg(WPARAM wParam,LPARAM lParam)

{

if(wParam==ID_COMMAND1)

{

...

return 1;

}

if(wParam==ID_COMMAND2)

{

...

return 1;

}

...

...

return SendMessage(WM_COMMAND,wParam,lParam);

}

then all command message from toolbar can be processed in general method.
