Attributes: GuidAttribute

Examples

The following code example creates a designer that provides designer verb menu commands that call methods of the IUIService. To use the example, compile the sample code to an assembly, and add a reference to the assembly in a Windows Forms application. If you are using Visual Studio, the IUIServiceExampleControl is automatically added to the Toolbox. Add an instance of the IUIServiceExampleControl to a Form. To access the designer verb commands that invoke IUIService methods, either right-click on the control's surface or click on the control's smart tag glyph and select an item from the smart tag panel.
