P/Invoke SendMessage and send either the WM_HSCROLL (0x0114) or the WM_VSCROLL (0x0115) messages to the control handle (see the Control.Handle property in the .NET Framework SDK). This has been covered many times here in the C# forum in the past, so I direct you to a previous response and urge you to try searching for answers first by clicking "Search comments" above the message board, or search the articles using the search textbox underneat the CodeProject logo.

I found the same problem as above and your description of the problem helped to give me the answer. If the path is closed already, the path.IsVisible(point) should work. To keep the line as pure looking as possible using pixels, just reverse the points in the array and add them to the original set. Then add them to a closed curve in the path. GraphicsPath _curvePath = new GraphicsPath(); List<PointF> closedCurvePoints = new List<PointF>(_curvePoints); closedCurvePoints.Reverse(); closedCurvePoints.AddRange(_curvePoints); _curvePath.AddClosedCurve(closedCurvePoints.ToArray()); This worked well for me - even for curves that backed in on themselves. Hopefully it will be helpful to someone else if you have no need for this info anymore

I have never done this, but from reading I think it is possible. You can create a manifest file using XML to tell your application to use the operating system's style. The file is placed in the same directory as your project, and is called myProject.exe.manifest I don't have a link for it at the moment, but I'm sure information will be readily available using google :) Hope it helps

See the Control.OnPaint method documentation in the .NET Framework SDK. Override this in your form. If you don't know how to perform owner drawing, then you better do a search here on CodeProject. It's not trivial. Microsoft MVP, Visual C# My Articles
