FIX: Atl70.dll causes a handle leak in the AtlAxWindowProc class in Visual Studio .NET 2002 (841817)



The information in this article applies to:

  • Microsoft Visual Studio .NET (2002), Academic Edition
  • Microsoft Visual Studio .NET (2002), Enterprise Architect Edition
  • Microsoft Visual Studio .NET (2002), Enterprise Developer Edition
  • Microsoft Visual Studio .NET (2002), Professional Edition

SYMPTOMS

When ActiveX controls are hosted in windows that are created by using the CAxWindow class, and then the windows are destroyed, the process of creating and of destroying the hosting window causes a handle leak. This problem occurs if none of the properties of the ActiveX controls are set.

If the process of creating and of destroying the windows is performed frequently, the process leads to handle starvation and unexpected application behavior. When ActiveX controls are hosted on the CAxWindow class, Microsoft Active Template Library (ATL) allocates a global handle that is not freed when the window is destroyed. This causes a handle leak.
