DOCUMENT:Q191858 26-AUG-1998 [vbwin] TITLE :BUG: Changing Appearance Property Reduces ListBox Height PRODUCT :Microsoft Visual Basic for Windows PROD/VER: OPER/SYS:WINDOWS KEYWORDS: ====================================================================== --------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual Basic Learning, Professional, and Enterprise Editions for Windows, version 6.0 --------------------------------------------------------------------- SYMPTOMS ======== When the Appearance property of a ListBox control is changed at run-time, the height of the ListBox control is reduced. RESOLUTION ========== Set the IntegralHeight property of the ListBox to False at design-time. STATUS ====== Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. MORE INFORMATION ================ Steps to Reproduce Behavior --------------------------- 1. Start a new Standard EXE project in Visual Basic. Form1 is created by default. 2. Add a ListBox control and a CommandButton to Form1. 3. Copy the following to the Code window of Form1: Option Explicit Private Sub Command1_Click() Debug.Print "Appearance property = " & List1.Appearance & _ " Height property = " & List1.Height If List1.Appearance = 0 Then List1.Appearance = 1 Else List1.Appearance = 0 End If End Sub 6. Open the Immediate Window. On the Run menu, select Start, or press the F5 key to start the program. Click the CommandButton. Note that every CommandButton click causes the ListBox height to change. If you set the IntegralHeight property of the ListBox to False, the bug behavior does not occur.
