OOPS, I copied and pasted the wrong line of code for my toolbarbutton
creation. But yes, I have both the Message Map and Button ID using the same
ID ( IDD_TOOLBAR_NEW). Yet my handler function still does not get called.

Your message map should have the entry for the appropriate ID of the
button. Why are you not adding the button in resource editor?

Hi there,

I am trying to capture the message that is sent when one of my toolbar
buttons are pressed.
I extended the CMFCToolBar class to :

   class CGraphToolBar : public CMFCToolBar

I have message map set accordingly:

   BEGIN_MESSAGE_MAP(CGraphToolBar, CMFCToolBar)
       ON_WM_CREATE()
       ON_WM_DESTROY()
       ON_COMMAND(IDD_TOOLBAR_NEW, OnNewElementBtn)
   END_MESSAGE_MAP()

in the constructor, i create all my buttons (using one as an example):

   m_saveBtn = new CMFCToolBarButton(IDD_TOOLBAR_SAVE,3);

I add the button in the OnCreate function:

   InsertButton(*m_saveBtn);

And i have a simple handler function:

   void CGraphToolBar::OnNewElementBtn(){
       TRACE0("CLICKED\n");
   }

When I run the program and click the button (the button is greyed out by
the way), I get this message instead:

   Warning: no message line prompt for ID 0x0032.

I'm not sure what I am doing wrong, where should I be capturing this
message?

Thanks,

Nick
