PRB: Error Connecting to MS Query with UserConnection Designer

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

SYMPTOMS

When using the UserConnection Designer, you receive the following message when attempting to build a query:

There was a problem attempting to communicate with MS Query.

CAUSE

The UserConnection Designer cannot find where MS Query is located on the system.

RESOLUTION

Make sure the proper registry key is pointing to where MS Query is located on the system. To do so, you must use RegEdit.

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

The correct registry key is found at the following location:

HKEY_LOCAL_MACHINE\Software\Microsoft\Shared Tools\VBQuery
