Windows Common Controls 5.0: Comctl32.ocxConsider the following scenario.
- You are running an application that sets a WinEvent hook on Microsoft Windows 2000 or a later operating system version.
- You start an application that uses the ListView control or the TreeView control from Microsoft Windows Common Controls 5.0.
The instruction at "0x202d0f51" referenced memory at "0x40000001". The memory could not be "written". Click on OK to terminate the program
Windows Common Controls 6.0: Mscomctl.ocxIf you are running an application that uses Mscomctl.ocx version 22.214.171.124 or a later version and the application contains a ListView control with the AllowColumnReorder property set to True, you receive the following error message when you try to reorder the columns:
The instruction at "0x27618848" referenced memory at "0x016e1e90". The memory could not be "read".
Note If you run your application in the Visual Basic 6 IDE, you will also experience both of these problems.
The problem with Windows Common Controls 6.0 occurs because of a change in version 126.96.36.199 of the Mscomctl.ocx file. Version 188.8.131.52 is included with hotfix 826287. Version 184.108.40.206 of the Mscomctl.ocx file changes the behavior of the ListView control when Visual Studio 6.0 is running on a computer that is running Windows XP or a later operating system. Most of the ImageList control calls in Mscomctl.ocx are wrappers of calls into the ImageList shell common control class that is defined in Comctl32.dll. However, the ImageList_GetImageRect method is not wrapped. This method still uses the earlier version of the ImageList structure and the earlier version of the ImageList control class that are defined in the Mscomctl.ocx file. This design causes a divide-by-zero error to occur during the column reorder operation.
Note The enclosed fix cannot be uninstalled or removed after it is installed.
