Remarks

To add a font combo box button to a toolbar, follow these steps:

Reserve a dummy resource ID for the button in the parent toolbar resource.
Construct a CMFCToolBarFontComboBox object.
In the message handler that processes the AFX_WM_RESETTOOLBAR message, replace the original button with the new combo box button by using CMFCToolBar::ReplaceButton.
Synchronize the font that is selected in the combo box with the font in the document by using the CMFCToolBarFontComboBox::SetFont method.

To synchronize the document's font with the font selected in the combo box, use the CMFCToolBarFontComboBox::GetFontDesc method to retrieve the attributes of the selected font, and use those attributes to create a CFont Class object.

The font combo box button calls the Win32 function EnumFontFamiliesEx to determine the screen and printer fonts available to the system.
