Issue that this hotfix rollup resolves

Issue 1

When you have a Windows Forms application that is running on a 64-bit operating system, the CheckedListBox or ComboBox control may not paint its items, and the control looks empty. This issue occurs because the control does not receive a WM_DRAWITEM message from its parent window. This issue occurs when the following conditions are true:

  • The owner-drawn control such as CheckedListBox has a negative window handle value.

  • The owner-drawn control's window handle is created in the constructor for the control’s parent form.

Negative window handles are created on the checked version of the 64-bit operating system, or when the handle is re-created many times on a retail build of the 64-bit operating system, such as when the application is running for a long time.

Usually, the control’s window is not created in the control's constructor. Therefore, the handle is also not created until after the parent form constructor is invoked. The second condition happens only when creation of the window handle is forced in the parent form constructor. One of the ways to force this creation is to change certain properties of the control, such as the BorderStyle property. When the child control’s handle is created before the parent's handle, the child control is temporarily parented to another window, and is re-parented later when the parent window is created. After the control is re-parented, the WM_DRAWITEM message is not routed correctly.

This hotfix fixes the message routing from the parent form to the owner-drawn control.
