BUG: InnerBottom/InnerRight Defines Gauge Fill Area Badly

 Last reviewed: June 21, 1995
Article ID: Q81461
The information in this article applies to:

- Professional Edition of Microsoft Visual Basic for Windows, 

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

SYMPTOMS

When you add the Gauge custom control to a form, the fill area defined by the InnerXXX properties is incorrect. Specifically, the InnerBottom sets the bottom border (InnerBottom - 1) pixels from the bottom-most position of the control. Similarly, the InnerRight property sets the right border (InnerRight - 1) pixels from the rightmost position of the control. This behavior occurs only in the InnerBottom and InnerRight properties.

WORKAROUND

To work around the problem, set InnerRight to (InnerLeft - 1) and InnerBottom to (InnerTop - 1) to create symmetrical borders. Note that in order to create a border of set width, you must account for the aspect ratio of your video display.

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

  1. 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.

  2. From the File menu, choose Add File (CTRL+F12). In the Files box, select the GAUGE.VBX custom control file. The Gauge tool will appear in the toolbox.

  3. Add the Gauge control to Form1 and set the gauge's properties as follows: 

       Properties    Values
   -------------------------------

   InnerBottom   1
   InnerLeft     1
   InnerRight    1
   InnerTop      1
   ForeColor     &H000000FF& (Red)
   Value         100
Notice that the bottom and right borders have completely disappeared. This problem can also be illustrated by setting BackColor and ForeColor to different colors. When InnerLeft is equal to InnerRight, the left and right borders are not symmetrical. The same holds true for the InnerTop and InnerBottom properties.
