SYMPTOMS
When you create a custom form using version 1.0 of Microsoft Electronic Forms Designer with the Gauge Custom Control from the Professional Edition of Microsoft Visual Basic version 2.0 for Windows, a corrupt .EXE file results. This .EXE file experiences a general protection (GP) fault at random times in the THREED.VBX or VBRUN.VBX file.

<div class="cause_section">

CAUSE
This is a problem with Visual Basic, and can be attributed to the following conditions:
 * Having a structure with substrings
 * Running a project from within Visual Basic at design time

<div class="resolution_section">

RESOLUTION
Always compile .EXE files from a clean load of the project. If you have run the project at design time, you have to save, exit, reload the project, and then build the .EXE file.

<div class="status_section">

STATUS
Microsoft has confirmed this to be a problem in the Professional Edition of Microsoft Visual Basic version 2.0 for Windows. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
