SYMPTOMS

When you use the GetSetting Function in Visual Basic 4.0, 16-bit, you may receive a General Protection Fault in Module Vba2.dll at 0011:360C. This error is likely to occur if you use an uninitialized, variable-length string as the argument for the default value of GetSetting.

RESOLUTION

To resolve the problem, use a fixed-length string or assign a value to the string. For example, modify the Load event code of Form1 in step 2 of the Steps to Reproduce Problem section of this article to the following:

   Dim DefaultValue As String
   DefaultValue = ""
   Call GetSetting ("MyINI", "SectionName", "KeyValue", DefaultValue)

   Dim DefaultValue As String * 40
   Call (GetSetting "MyINI", "SectionName", "KeyValue", DefaultValue)

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
