>>Yes I guess you can compare it to a standing progress bar. The control must have properties like: Increase, Decrease, Temperature (get and set). (if the control is on a form in an app that is hooked up to a device that can measure body temperature I would like my body temperature to be reflected by the user control <g>, but that is not what I will be using the control for. I have a form with a numericupdown control where the user can set the temperature, the only thing I want the thermometer control for is for a visual effect.

You can then put everything on a special control if you want to reuse the whole group but othrwise you can just use it like this. Is there anything more complex I'm missing there?

I think that is pretty much it. I just find it odd that there is nothing free out there like that. Hmm maybe I have an idea for my first CodeProject artice. The only thing I am afraid might get complex is the resizing of the user control. I might have to play around with this tonight.
