PRA: GP Fault When Using Erase Statement on String Array

Article ID: Q100168
Creation Date: 16-JUN-1993
Revision Date: 19-SEP-1996 The information in this article applies to:

Microsoft Access versions 1.0 and 1.1

SYMPTOMS

When you use an Erase statement on a string array, you receive a general protection (GP) fault. The following error message appears:

   An error has occurred in your application. If you choose Ignore,
   you should save your work in a new file. If you choose Close, your
   application will terminate.

CAUSE

You are trying to use the Erase statement on a string array contained in a user-defined data type.

RESOLUTION

Use a loop structure to initialize the string array in the data type.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Access versions 1.0 and 1.1. This problem no longer occurs in Microsoft Access version 2.0.

MORE INFORMATION

Steps to Reproduce Problem

The following code generates the error message described above:

   Type Foosball
      X(1) As String
   End Type

   Sub Main ()
      Dim Arrays As Foosball
      Erase Arrays.X
   End Sub

To work around this problem, use the following loop structure instead of the Erase statement:

   Sub Main ()
      Dim Arrays As Foosball
      For i = 1 To UBound(Arrays.X)
         Arrays.X(i) = ""
      Next i
   End Sub
