SYMPTOMS
When you start the Class Browser, one or more of the following errors appears:

OLE error code 0x80040154: Class not registered. OLE object is being ignored. Record number 13. OK, or Cancel

Clicking OK and selecting a class library from the Open dialog box causes the following Class Browser error to appear:

Unknown member OLECLASSLIST.

Browser: classbrowser

Object: classbrowser

Method: setbusystate OK, or Cancel

When you click OK or Cancel, the following message appears where xyz is the name of the class library you selected:

Unable to create class list for xyz.vcx



CAUSE
The Class Browser depends on the Outline Control (Msoutl32.ocx) to be registered correctly in the Windows 3.x Reg.dat file. The outline control registration in the Reg.dat file is missing or invalid.



RESOLUTION
Register the Msoutl32.ocx OLE control by running the following command in Windows:

C:\VFP\SAMPLES\OLE\REGSVR32.EXE C:\WINDOWS\SYSTEM\MSOUTL32.OCX

To run this command in Windows 95, click Run on the Start menu. To run it in Windows 3.x, click Run on the File menu in File Manager.

If running the command does not fix the problem, rebuild the Reg.dat file, and run the command again.

For information on how to rebuild the Reg.dat file, please see the following article in the Microsoft Knowledge Base:

80393 How to Rebuild the Default Windows Reg.dat File



STATUS
Microsoft has confirmed this to be a problem in the Microsoft product listed at the beginning of this article. This problem was corrected in Microsoft Visual FoxPro 3.0b for Windows.



MORE INFORMATION
This problem is specific to Visual FoxPro 3.0 running under Microsoft Windows 3.x. When running Visual FoxPro 3.0 under Microsoft Windows 95 or Microsoft Windows NT, the outline control will autoregister itself if needed.

Steps to Reproduce Behavior
 In Windows 3.x, unregister the outline control by running the following command (on the File Manager File menu, click Run):

C:\VFP\SAMPLES\OLE\REGSVR32.EXE C:\WINDOWS\SYSTEM\MSOUTL32.OCX /U

 Start Visual FoxPro, and then start the Class Browser.
