PRB: Cannot Add Windows Common Controls or Common Dialog Control to Project

ID: Q221990

The information in this article applies to:

Microsoft Visual Basic Learning, Professional, and Enterprise Editions for Windows, versions 5.0, 6.0

SYMPTOMS

IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

Visual Basic 6.0 and Visual Basic 5.0 are both installed on the same system. After uninstalling Visual Basic 6.0, the following error appears when you attempt to add the Windows Common Controls or the Common Dialog control to a Visual Basic 5.0 project:

Error
Could Not Be Loaded

CAUSE

The registry contains a reference to a control version that was removed by uninstalling Visual Basic 6.0.

RESOLUTION

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

Delete the registry key for the problem control from:


HKEY_CLASSES_ROOT\TypeLib

and re-register it. For additional information about deleting and re-registering an ActiveX control, please refer to the following article in the Microsoft Knowledge Base:

Q217180 HOWTO: Delete and Re-Register TypeLib GUID for ActiveX Control

MORE INFORMATION

The following are the Class ID numbers for the controls known to be affected by this problem:

ActiveX Control File Name Class ID

Windows Common Controls comctl32.ocx 6B7E6392-850A-101B-AFC0-4210102A8DA7

Common Dialog Control comdlg32.ocx F9043C88-F6F2-101A-A3C9-08002B2F49FB

When you locate the Class ID folder for these controls in the registry, the folder will contain a version folder. This version folder contains the version entries for these controls.

Installing multiple versions of the same ActiveX control results in multiple entries in the version folder. Deleting the ActiveX folder from the registry and then registering the control will add the correct entries to the registry.
