);

Parameters

lpClassID

[in, out] A pointer to the class identifier (CLSID) of the form.

The class identifier was successfully returned.

Remarks

The IPersistMessge::GetClassID method sets the contents of the lpClassID parameter to the form server's class identifier and returns S_OK. When a form viewer calls GetClassID and it returns successfully, the form is placed in the Uninitialized state.
