The information in this article applies to:

  • Microsoft Windows Software Development Kit (SDK) versions 3.1
  • Microsoft Win32 Application Programming Interface (API) included with: 

        - Microsoft Windows NT versions 3.5, 3.51
    - Microsoft Windows 95 version 4.0

SYMPTOMS

When the user resizes or moves the parent window of an open drop- down combo box, the list box portion of the combo box does not move.

CAUSE

The list box portion of the combo box does not receive a move message. Therefore, it remains on the screen at its original position.

RESOLUTION

Close the drop down list before the combo box is moved. To perform this task, during the processing of the WM_PAINT message, send the combo box a CB_SHOWDROPDOWN message with the wParam set to FALSE.
