THANKS :)

Thanx mav :)

thanks :)

It works :) Thaky you :)

Well, I've seen some strange things happen when I've added private classes to some of my form-derived classes. X| Basically, the visual designer stores some resources in .resx files (for example image data). These XML-based files hold serialized data that can be retrieved by an object name (just add a picture box to a form and than look at what's generated in InitializeComponent()). If, by which means ever, such a resource cannot be found than the visual designer will choke and running the application will create an exception similar to what adnan wrote. I think that he had introduced some naming conflicts, so removing the offending struct declarations from the .cs file fixed the way .NET accesses its embedded resource streams. mav

I would make the code look like this: private void panel13_Paint(object sender, System.Windows.Forms.PaintEventArgs e) { ArrayList nodes = new ArrayList(); StreamReader sr = File.OpenText("C:\\NeckingRa\\Temp\\cut.dat"); String line; while ((line=sr.ReadLine())!=null) { string[] values = line.Split(' '); nodes.AddRange(values); } sr.Close(); } The file variable is not needed and inside of the while look you were reading to the end of the file. Also you had never added the data in values to the nodes variable. I also like using @"c:\NeckingRa\Temp\cut.dat" in C# instead of the normal \\ that we all had to use in C++. Steve Maier, MCSD MCAD

For plotting your node list you could derive a class from Panel and then override the OnPaint function. I'd save the ArrayList of Points as a property of your new class: protected ArrayList _graph = new ArrayList(); public ArrayList GraphPoints { get { return _graph; } set { _graph = value; Invalidate(); } } Then you can write something like this in the overridden function: protected override void OnPaint(PaintEventArgs pe) { Point[] points = new Point[GraphPoints .Count]; GraphPoints .CopyTo(points); // DrawLines assumes (0,0) to be top left of the panel, so you might have // to perform some coordinate transformation... pe.Graphics.DrawLines(Pens.Red, points); } Regards, mav

Thank U, it works now.. Great, I am very very thankful for Your Help.. There are still a lot of Great an Cool people outthere in the World.. Once again Thanx :)
