BUG: Gauge Custom Control: No Error for Illegal NeedleWidth

ID: Q80905

The information in this article applies to:

Microsoft Visual Basic Professional Edition for Windows, versions 2.0, 3.0
Microsoft Professional Toolkit for Microsoft Visual Basic programming system for Windows, version 1.0

SYMPTOMS

When you use the Gauge custom control, setting the NeedleWidth property to an invalid value fails to generate an error. Furthermore, attempting to set the NeedleWidth property outside its valid range will reset the NeedleWidth property to 1. This behavior occurs at both design time and run time.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Steps to Reproduce Problem

Start Visual Basic or from the File menu, choose New Project (ALT, F, N) if Visual Basic is already running. Form1 is created by default.

From the File menu, choose Add File (CTRL+F12), and select GAUGE.VBX to add the Gauge control to the Toolbox. The Gauge tool will appear in the Toolbox.

Add the Gauge control to Form1 and set the gauge's Style property to 2 - 'Semi' Needle or 3 - 'Full' Needle.

Add the following code to the Form_Click event procedure.


   Sub Form_Click ()
      Gauge1.NeedleWidth = -3
      MsgBox "NeedleWidth = " + Str$(Gauge1.NeedleWidth)
   End Sub

From the Run menu, choose Start (ALT, R, S) to run the program.

Notice that clicking the form produces a message box that displays the value of the gauge's NeedleWidth property. Even though the NeedleWidth is explicitly set to -3 before the message box is displayed, the NeedleWidth property resets to a value of 1.
