When I attempt to build the application I receive the following error:

Error    10    The type 'AxSHDocVw.AxWebBrowser' is defined in an assembly that is not referenced. You must add a reference to assembly 'AxInterop.SHDocVw, Version=1.1.0.0, Culture=neutral, PublicKeyToken=90ba9c70f846762e'.    C:\Tools\QueryCommander_source_4.0.0.0\QueryCommander_4_0_0_0\WinGui\MainForm.cs    2603    4    QueryCommander

Does anyone have any suggestions?

TIA.
