Buttons on CDialogBar

Hi,
 I am trying to add a button to a CDialogBar.  I add the button with no   
trouble and when the program runs the button is always disabled.  Just   
for kicks in the OnIdle function I enabled it, whenever I enable it is   
immediately disabled.

 I also added a button to the CTRLBARS code from the Dev Net and it does   
the same thing.  Any suggestions for adding buttons to CDialogBar's would   
be much appreciated.

Thanks,

Chris

Christine,
	I am not sure how you mean you are adding the button dynamically or in =
the resource editor. By what you stated in your e-mail I'll assume the =
resource editor.  So here goes : Dialog bars are part of the main window =
and all of the control notifications are sent to the parent of the =
dialog bar. So if your application was an SDI application your dialog =
bar was probably attached to CMainFrame. So you must handle the messages =
in the parent which in this case is the main frame. If your application =
was an MDI then you need to handle the messages in the parent of the =
frame of the MDI frame you dialog is attached to. For further =
information take a look at the MFC Encyclopedia in the Visual C++ Books =
on line under Dialog Bars.  This means you will have to put a message =
handler in your Frame for the button. It should then be enabled. Good =
Luck.

Add a commandhandler or updateui handler for your button
	ON_COMMAND(ID_DIALOGBAR_BUTTON, OnDialogBarButton)
	ON_UPDATE_COMMAND_UI(ID_DIALOGBAR_BUTTON, OnUpdateDialogBarButton)
to the message map where you want to handle messages from your button

Hi Chris, 

just add manually to your MESSAGE_MAP a ON_UPDATE_COMMAND_UI handler and a
function to say TRUE !

BEGIN_MESSAGE_MAP(CDialogBar_Search, CDialogBar_DDX)
	ON_BN_CLICKED(IDC_BUTTON_TEST, OnButtonTest)
	ON_UPDATE_COMMAND_UI(IDC_BUTTON_TEST, OnUpdateButtonTest)
END_MESSAGE_MAP()

void CDialogBar_Test::OnUpdateButtonTest(CCmdUI* pCmdUI) 
{
	// TODO: Add your command update UI handler code here
	pCmdUI->Enable (TRUE);	//or whatever you want
}

Is you look into the MFC Online help on CDialogBar, it states that buttons
on a CDialogBar will be disabled by the framework unless you handle it
messages in its parent class.

I recently had the same problem, simply add an:

ON_COMMAND(, ) 

to either the CView or CMainFrame derived class (both are considered
parents of the CDialogBar) and it should work.

This is the "quick and dirty" method. Hopefully someone will give you a
more detailed explaination -- I am also curious.

I think you need to have that button appear in
a message map (whatever class will
handle the button being pressed).
ON_BN_CLICKED(IDC_BUTTON, OnButton)
(use class wizard to make life easier).
