DIAL.EXE: Dial Control Sample (175213)
The information in this article applies to:

This article was previously published under Q175213 SUMMARY
The Dial control is a circular slider control similar to a volume knob
found on a stereo system. This control can be used in a situation where you
want the functionality of a regular slider control but lack the space. If
the Limit property is set to true, the Dial control operates as a normal
slider control. The Value can be increased and decreased between the limits
defined by Min and Max properties.
With the Limit property set to False, the Dial can be used to make
adjustments to large numbers. For example, use the Dial to adjust the
margin of a control. Each revolution of the dial increases or decreases the
value by (Min - Max). This could allow for "fine tuning" of the number,
while allowing for rapid variations.
The sample project is available from the Visual Basic Owner's site at
http://premium.microsoft.com/download/vbasic/dial.exe. Only registered
users of Visual Basic can access this site.
MORE INFORMATION
The Dial control has two modes: limited and non-limited. In limited mode,
the minimum and maximum values determine the limits possible within one
revolution. The dial can be turned only one revolution.
In the non-limited mode, the minimum and maximum values set the range of
the dial in one revolution. However, the dial can be turned unlimited
revolutions. So, the limited mode could be used to adjust a value between
two extremes, such as 1 and 100. The non-limited mode could be used to
determine how much adjustment is possible in the margins of a page. Each
revolution could equal one inch.
