PRB: Disk or Network Error When Trying to Run Database App (150943)
The information in this article applies to:
- Microsoft Visual Basic Standard Edition, 32-bit, for Windows 4.0
- Microsoft Visual Basic Professional Edition, 32-bit, for Windows 4.0
- Microsoft Visual Basic Enterprise Edition, 32-bit, for Windows 4.0
This article was previously published under Q150943 SYMPTOMS
Any attempt to run a project or executable that accesses a database fails
with error 3043 "Disk or Network Error" or a Page Fault.
CAUSE
This behavior is caused by an invalid or non-existent Temp or TMP
directory. The problem only affects applications running on Windows NT.
Windows 95, Windows 98, and Windows 2000 will create a default Temp directory if one does not exist or is invalid.
The following combinations of these two environment variables cause
the problem:
TMP missing and Temp missing
TMP invalid and Temp missing
TMP missing and Temp invalid
RESOLUTION
Using the System applet in the Control Panel, add or correct the
environment variable named "Temp" so it points to a valid directory for
temporary files such as:
Temp=C:\WINNT35\Temp
Using the System applet in the Control Panel, add or correct the
environment variable named "TMP" so it points to a valid directory for
temporary files such as:
TMP=C:\WINNT35\Temp
Reboot, and note that the database applications run properly.
STATUS
Microsoft has confirmed this to be an issue in the Microsoft products
listed at the beginning of this article. We are researching this issue
and will post new information here in the Microsoft Knowledge Base as it
becomes available.
MORE INFORMATION
The Microsoft Jet engine version 3.0, used by Visual Basic 4.0 to gain
access to databases, looks for a Temp or TMP environment variable pointing
to a valid directory in which to store the necessary temporary files. If
this information cannot be obtained, an error condition is encountered. The
version of the Jet engine that ships with Visual Basic 4.0 incorrectly
causes a Page Fault when an error condition is encountered. The version of
the Jet engine that ships with Access 95 and Visual Basic 4.0a correctly
handles the error and displays the "Disk or Network Error" error message.
