When to use
Use this class to access the methods of ISecurityCallContext.
Remarks
You cannot directly create a SecurityCallContext object. To use the methods of ISecurityCallContext, you must obtain a reference to its implementation by calling CoGetCallContext, supplying IID_ISecurityCallContext for the riid parameter.
To use this class from Microsoft Visual Basic, add a reference to the COM+ Services Type Library. A SecurityCallContext object can be declared using "COMSVCSLib.SecurityCallContext" as the class name; it is created by calling GetSecurityCallContext.
