SYMPTOMS
When an OleControl is subclassed, the following error message appears in Visual FoxPro:

OLE error code 0x80004005: Unspecified error.

Visual FoxPro 5.0 generates this error message:

Object class is invalid for this container.



WORKAROUND
Create a new class with the name you want based on the subclass that was just created.



STATUS
Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.



Steps to Reproduce Problem
  To create a new class, type the following code in the Command window: CREATE CLASS comm1 OF comms AS olecontrol  Select the "Create Control" option and then select the Microsoft Comm Control. Click OK. When the Class Designer comes up, save and close the new class.  To try to rename the new class, type the following in the Command window: RENAME CLASS comm1 OF comms TO mycomm </ol>

At this point, Visual FoxPro generates the error.
