Embed and display the VBA control and UserForm in the Excel document

Implementation environment: Visual Studio 2010, Excel 2010, VSTO 4.0

Embed a Commandbutton in the document and click it to display a UserForm. A CommandButton clicking on UserForm will pop up a message box, And the CommandButton Caption will change. When UserForm is disabled, the CommandButton Caption in the document is changed.
