Adding a multitude of lines

Apr 11 2011 3:03 PM
Right now I'm trying to draw a printable form - I have the print working properly right now but I need to get lines to be drawn on the form. Right now I'm using a button with

[code]
private void button1_Click_1(object sender, EventArgs e)
{
int BiggestSize = 100;
panel5.Paint += new PaintEventHandler(LinePainter);
Value1 = 1;
Value2 = BiggestSize;
Value3 = panel5.Width;
Value4 = BiggestSize;
}
[/code]

[code]
private void LinePainter(object sender, PaintEventArgs Painte)
{
Pen ColourPen = new Pen(System.Drawing.Color.Red);
int ColourPosition = 1;
if (Company == "MCI")
{
switch(ColourPosition)
{

case 1:
ColourPen.Color = (System.Drawing.Color.MediumSlateBlue);
ColourPosition = 2;
break;
case 2:
ColourPen.Color = (System.Drawing.Color.DarkOliveGreen);
ColourPosition = 3;
break;
case 3:
ColourPen.Color = (System.Drawing.Color.DarkOrange);
ColourPosition = 1;
break;
}

}
else if (Company == "SteelWorks")
{
switch (ColourPosition)
{
case 1:
ColourPen = new Pen(System.Drawing.Color.MediumSlateBlue);
ColourPosition = 2;
break;
case 2:
ColourPen = new Pen(System.Drawing.Color.MediumSlateBlue);
ColourPosition = 3;
break;
case 3:
ColourPen = new Pen(System.Drawing.Color.MediumSlateBlue);
ColourPosition = 1;
break;
}
}

System.Drawing.Graphics graphicsOBJ;
graphicsOBJ = this.panel5.CreateGraphics();
graphicsOBJ.DrawLine(ColourPen, new Point(Value1, Value2),new Point(Value3, Value4));
//Painte.Graphics.DrawLine(ColourPen, V1, V2, V3, V4);
//Painte.Dispose();
label1.Text = ColourPosition.ToString();
}
[/code]

I can't get the switch to work as well, but that seems to be because the eventhandler throws itself as always on (if I change the label1.text in my code, it changes on the form without me pressing the button).

I've tried to find out how to turn this into an instanced version of a drawing creation but can't quite get the right info on it. Any help?

My end goal is to draw a line as many time as is required by the user - in this case, when they press button1.
