FIX: Accessibility error occurs when you configure a UDL file on a computer that is running a 64-bit operating system (838768)


The information in this article applies to:

  • Microsoft Data Access Components 2.8

SYMPTOMS

When you try to configure a Universal Data Link (UDL) file for the OLE DB sample provider on a computer that is running a 64-bit operating system, you may receive the following error message:
Properties you entered cannot be saved because the Data Link file is inaccessible. Ensure that the hard drive or network share is still available.

CAUSE

A coding error in the OLE DB sample provider sets the dialog window handle to a 32-bit pointer value instead of to a 64-bit pointer value. When the pointer value is set to 34-bit, the information for the 64-bit operating system is missing.
