System_CAPS_pubmethodGetTypeAttr(IntPtr%)

Retrieves a TYPEATTR structure that contains the attributes of the type description.

System_CAPS_pubmethodGetTypeComp(ITypeComp^%)

Retrieves the ITypeComp interface for the type description, which enables a client compiler to bind to the type description's members.

System_CAPS_pubmethodGetVarDesc(Int32, IntPtr%)

Retrieves a VARDESC structure that describes the specified variable.

System_CAPS_pubmethodInvoke(Object^, Int32, Int16, DISPPARAMS%, IntPtr, IntPtr, Int32%)

Invokes a method, or accesses a property of an object, that implements the interface described by the type description.

System_CAPS_pubmethodReleaseFuncDesc(IntPtr)

Releases a FUNCDESC structure previously returned by the GetFuncDesc method.
