This is my first post and is not a long tip due my poor English and my limited time (sorry for the mistakes), but I hope the source code will be useful for someone.
I'm working on small DAW project and some time ago, I needed a very simple knob control, easy to use and configure. To practice draw with GDI, I decided to write my own and here is the result (please take a look at the attached source code). The project is developed with SharpDevelop, a free IDE for .NET.
The control has been created with the purpose of translating it later to C++/wxWidgets.
The properties of the control are very similar to slider control of .NET library.
Any suggestions or bug reports are highly appreciated.
Thanks to all developers who have shared interesting articles.
