RectTracker

I am looking for .NET class which works like MFC CrectTracker. RectTracker from CodeProject http://www.codeproject.com/cs/miscctrl/CSharpRectTracker.asp is good for moving controls on the form, but I need object which moves itself over image. It should not be control itself, and should not contain other controls - exactly like MFC CRectTracker - just draws itself and handles mouse messages.
If there is such class, please post a link.

So you want to be able to draw resizeable/moveable boxes on top of a PictureBox?

Sorta like these?

Idle_Mind, this class is working, but requires a lot of client code. I am looking for something that fully encapsulates all functionality, with minimum client code.
CRectTracker has the following interface:
1) public Rectangle member which can be set and read.
2) Virtual Draw function which draws rectangle and resizing handles (both rectangle and handles are optional). Called by client from WM_PAINT handler.
3) HitTest function which detects whether tracker is clicked. Called by client from WM_MOUSEDOWN handler.
4) Track function which moves/resizes tracker. This function is called by client when HitTest is positive. Function returns when user releases mouse button. During resizing/moving CRectTracker draws itself using DrawFocusRect, without invalidating parent window.

I am looking something like this.

bruintje, my WinRar cannot open rar archive from your link. Do you have another link, or maybe you can post the code?

Life is not so easy, I spent some time with CRectTracker class. Finally I removed 70% of it's code, reduced functionality to minimum required for my case, fixed some bugs and got working version.
bruintje, thank you for the link. Idle_Mind, thank you for some ideas in your implementation.
