To enable IDE Integration in Visual Basic and Visual C++:
Go to Tools on the Vault Professional client menu bar. Select Options.
Under General Options, check “Make Vault Professional your default SCC provider”.
To disable IDE Integration, uncheck the box.
The default setting is unchecked.
The “Express” versions of Visual Studio do not support source control integration and enabling this option does not override these limitations.
You can select Vault Professional Classic Client IDE Integration in Visual Studio 2005 and later by clicking Tools->Options->Source Control->Plugin Selection and selecting SourceGear Vault Professional Classic Client for the current source control plugin.
