Specifying the include directory for MDSC.idl
This step is not necessary if you copied MDSC.idl to the project directory.
1 On the File View tab in the Visual C++ Workspace pane, select the project’s .idl file, and then click Project > Settings.
The Project Settings dialog opens.
2 In the Settings For list, select All Configurations, and then click the MIDL tab.
3 In Additional Include Directories, enter the location of MDSC.idl. If any of the folder names contain spaces (for example, the default installation folder), enter their short names.
4 Click OK.
