FIX: GPF Issuing QUIT from a Form Run in the Form Designer
This article was previously published under Q186368
A General Protection Fault occurs when you run a form from the form
designer. Under Windows 95, the following message appears:
This program has performed an illegal operation and will be shut down.
If the problem persists, contact the program vendor.
Under Windows NT 4.0, the following message appears:
The instruction at "0xnnnnnnnn" referenced memory at "0xnnnnnnnn."
The memory could not be "read."
Click on OK to terminate the application.
Click on Cancel to debug the application.
This behavior occurs because a QUIT command executed while the form
designer was open. The problem is not limited to form methods or events.
Do not issue a QUIT command in a form's events or methods while in the Form
Designer.
Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article. This has been corrected in Visual FoxPro
6.0.
Steps to Reproduce Behavior
WARNING: Before attempting to reproduce this behavior, it is strongly
recommended that you close any open tables.
- Using Visual FoxPro 5.0, create a new form.
- In the form's Destroy event, add the following code:
- Close the Code window.
- Select Form, Run Form from the Menu bar.
- Click the form's Close button AND NOTE THAT a General Protection Fault
occurs.
