When a CommandBarButton is created from a Command on a Visual Studio menu, it has an icon and a text. However, when it is created on a toolbar, it can have only an icon, or an icon and a text. Typically buttons on a toolbar have only an icon (without a text). There are two ways to set that style (only the icon) to a CommandBarButton on a toolbar:
- Setting the CommandBarButton.Style = MsoButtonStyle.msoButtonIcon. This approach has the drawback that Visual Studio first creates the button with icon and text, and then it changes it to icon only.
- Setting the default style of a command to EnvDTE80.vsCommandStyle.vsCommandStylePict, so that CommandBarButtons created on toolbars have only the icon, while those created on menus have icon with text (the only possible style for them).
My latest article shows a sample of the second approach:
