FIX: GDI Handles Leak When You Assign an Icon to a Windows Form (819633)


The information in this article applies to:

  • Microsoft .NET Framework 1.0 SP2

SYMPTOMS

If you add an icon resource to a Microsoft Windows Form, up to 2 GDI handles may be leaked. For example, this problem occurs if the Form.Icon property is set to an icon that has been generated by Icon.FromHandle.

You can view the number of GDI objects that a process uses in Windows Task Manager. To do this, click Select columns on the View menu, and then click to select the check box for GDI Objects to add the GDI objects count to the default view.
