FIX: Memory Leak When Scroll Database Designer in Windows 95 (138233)

SYMPTOMS

In Visual FoxPro, scrolling in the Database Designer decreases the amount of available System and GDI resources. If available resources fall below 10% you receive this message:

Ninety percent or more of your system resources are in use. To free up system resources, quit any programs that you are not using. If you do not, your computer may stop responding.

If resources are not released and continue to fall, you receive this error message:

This program has performed an illegal operation and will be shut down. If the problem persists, contact the program vendor.

WORKAROUND

Close the files you're currently working with, and restart Visual FoxPro to release system resources. Wherever possible, avoid scrolling in the Database Designer.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem was corrected in Visual FoxPro 3.0b for Windows.

MORE INFORMATION

Steps to Reproduce Problem

Scroll in the Database Designer while running the Resource Meter that is shipped with Windows 95. You will see the System and GDI resources decrease. To find the Resource Meter, on the Start menu, click Programs, then click Accessories, and click System Tools. Click Resource Meter to put an icon in the lower-right corner of your screen. Double-click this icon to see the Resource Meter window.
Open the database designer and use the scroll bars to move up and down in the Database Designer. The amount of memory that is lost each time you scroll depends on the number of tables you have in your Database Designer window.
