SYMPTOMS

When a Visual Basic program uses the data report designer to create and print a large number of reports (typically 700 or more), the program may fail and you may receive the following error message:
Error obtaining printer status
You must restart the program to continue printing.

CAUSE

Each time that you call the PrintReport method of the Data Report, it creates a new thread to handle the printing job in the background. Data Report keeps the handles of these background threads so that it may cancel the printing jobs. This problem occurs because Data Report does not release these handles after the threads are closed.

RESOLUTION

A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Visual Studio 6.0 service pack that contains this fix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:

NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The typical support costs will apply to additional support questions and issues that do not qualify for the specific update in question.
