The information in this article applies to: - Professional Edition of Microsoft Visual Basic for Windows, version 2.0 - Microsoft Professional Toolkit for Microsoft Visual Basic programming system for Windows, version 1.0
SYMPTOMSWhen you use the Gauge custom control, a linear gauge (Style 0) will fail to fill the leftmost column of pixels in the fill area whenever Gauge1.Max - Gauge1.Min is greater than 100. Similarly, the bottom-most row of pixels in the fill area of the horizontal gauge will not be filled given the same condition. The column or row of pixels not filled are cleared to the BackGround color because the inner area is cleared using the BackGround color whenever the Gauge's fill area is updated.
STATUSMicrosoft has confirmed this to be a bug in the products listed above. This problem was corrected in Microsoft Visual Basic version 3.0 for Windows.
MORE INFORMATION
Steps to Reproduce Problem in Visual Basic Version 1.01. 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.
