FIX: Using Set for ListItem's SubItem Results in GPF

Last reviewed: December 18, 1997
Article ID: Q171577
The information in this article applies to:
  • Microsoft Visual Basic Professional and Enterprise Editions for Windows, version 5.0
  • Microsoft Visual Studio 97 ---------------------------------------------------------------------

SYMPTOMS

Using the Set keyword when setting the value of a ListItem's SubItem results in a General Protection Fault.

CAUSE

The SubItems collection of the ListItem is designed to handle strings, not objects.

RESOLUTION

Do not use the Set keyword. Instead of code similar to:

   Set ListItem.SubItems(1) = Text1

use the following code:

   ListItem.SubItems(1) = Text1

where Text1 is a textbox object.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug has been fixed in Visual Studio 97 Service Pack 2.

MORE INFORMATION

Although the code listed above that uses the Set keyword is incorrect, it should not result in a General Protection Fault. Once the Visual Studio 97 Service Pack 2 is installed, the Visual Basic correctly raises the "Type Mismatch" error.
