Enabling & Disabling Toolbar items at runtime in MFC SDI...

Hi,

I have an SDI application containing a Menu (IDR_MENU) and a Toolbar (IDR_TOOLBAR1).

When a perform click a certain button or menu item (RUN), I want specific menu items and Toolbar icons to become disabled.  Each associated Toolbar Icon and Menu Item have the same ID (ID_ABORT for example).

I use the following to disable the 'Abort' functionality when it is NOT running...

void CMainFrame::OnUpdateFileAbort(CCmdUI* pCmdUI)
{
   if (isRunning == false) pCmdUI->Enable(FALSE);
}

This works fine for the Menu item, but does not change the Toolbar icon.

Any ideas where I am going wrong...

void CMainFrame::OnUpdateFileAbort(CCmdUI* pCmdUI)
{
  pCmdUI->Enable(! running);
}

This should work in standard SDI application created by MGC Application Wizard. Just set running flag when necessary.

Please make sure that the toolbar is also using the same id.

I get the same response - Menu works as expected, Toolbar does not change.  IDs are the same in the Menu & Toolbar...

As the function that sets the variable to enable & disable the toolbar & menu items is sequencial, do I need to FORCE some sort of update to occur DURING its execution ?

i.e.
void CMyView::DoIt()
{
   Running = true;
   <Force the toolbar to update>
   ... Do some stuff ...
   <Force the toolbar to update>
   Running = false;
}

OK, now it is clear. <Force the toolbar to update> is:

CWinApp::OnIdle(0);
