After you implement Help About and splash screen support, you can test your implementation in Visual Studio.
To test the Help About dialog box
- From the Visual Studio command prompt, run devenv.exe with the /setup switch. To run in the experimental environment, type: - devenv /rootsuffix Exp /setup - Note You have to repeat this step only when you change the Help About screen information. 
- Run Visual Studio in the same registry root as was mentioned earlier, but without the /setup switch: - devenv /rootsuffix Exp 
- On the Help menu, click About Microsoft Visual Studio. - Your VSPackage name appears in the Installed products list. 
- Select your VSPackage from the list. - Your VSPackage product information appears in the Product details text box. 
To test the splash screen
- Run devenv.exe with the /setup switch. To run in the experimental environment, type: - devenv /rootsuffix Exp /setup - Note You have to repeat this step only when you change the splash screen information. 
- Run Visual Studio in the same registry root as was mentioned earlier, but with the /splash switch instead of the /setup switch. - devenv /rootsuffix Exp /splash - Your VSPackage product information and logo appear on the splash screen.
