Hi flybird,

You can use the Graphics object to draw lines or any shape for that matter.

Eg. the following code in the form paint event draws a black line that
is 90 pix wide:

private void Form1_Paint(object sender,
System.Windows.Forms.PaintEventArgs e)
{
e.Graphics.DrawLine(new Pen(Color.Black, 1), 10, 10, 100, 10);
}

HTH,
APG

You're referring to the VB 6 Line Control, right?

In .NET, you'll need to investigate the System.Drawing namespace and the
Graphics class, which includes the public method DrawLine. Here is a basic
example from the help:

[C#]
public void DrawLineFloat(PaintEventArgs e)
{
// Create pen.
Pen blackPen = new Pen(Color.Black, 3);
// Create coordinates of points that define line.
float x1 = 100.0F;
float y1 = 100.0F;
float x2 = 500.0F;
float y2 = 100.0F;
// Draw line to screen.
e.Graphics.DrawLine(blackPen, x1, y1, x2, y2);
}
