SYMPTOMS

When you include one of the stock CDK property pages (Font, Color, or Picture) in your application, it may not appear when the property sheet dialog box is displayed. The default and other custom property pages may still be visible.

CAUSE

One possible cause of this problem is the lack of registration of the DLL which includes the stock property page implementations.

Depending on the version of Visual C++, this DLL is: 
VC 2.X ==> OC30.DLL
VC 4.0, VC 4.1 ==> MFC40.DLL
VC 4.2 ==> MFC42.DLL

RESOLUTION

Register the appropriate DLL using regsrv32.exe that comes with the CDK and is located in the CDK \Bin directory. Use this line: 
   REGSVR32 OC30.DLL

STATUS

Microsoft is researching this behavior and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Microsoft has seen several cases where Oc30.dll was either not registered at all or only partially registered. We have not been able to isolate the cause of this failure.

Before attempting to register OC30.DLL, confirm that it is in the System32 directory in Windows NT and the System directory in Windows 95.

Steps to Reproduce Behavior

To demonstrate the problem, first confirm that the CIRC3 sample has been compiled and registered. Confirm that the Font and Color property pages are seen when the control is run by looking at the property sheet from the menu selection Edit Properties. Then follow these steps:

  1. Delete the Font class ID from the HKEY_CLASSES_ROOT\CLSID. The CLSID for the Font property page is:

    {2542F180-3532-1069-A2CD-00AA0034B50B}.

  2. Run a container (On the Tools menu, click Test Container in Visual C++), and insert the CIRC3 Ole control.
  3. On the Edit menu, click Properties, and note that the Font property page is no longer visible.
You could also delete the Color property page ID:

{DDF5A00-B9C0-101A-AF1A-00AA0034B50B}

Or the Picture proper page ID:

{FC7AF71D-FC74-101A-84ED-08002B2EC713}

NOTE: The class IDs for these property pages are different under Visual C++ version 4.x
