Hi,

I'm going some drawing via "Graphics" in a "Paint" callback and the commands
will only manifest themselves if I minimise the window and then maximise it
again.

I'm new to windows programming and so I am obviously missing a lot of the
basics when it comes to this sort of thing but my mandate is to get a
utility up and running ASAP.

What's the magic function call I'm missing?

Many thanks,

R.

private void PictureBox_Paint(object sender,
System.Windows.Forms.PaintEventArgs e)
{

Graphics graphics = e.Graphics;

System.Drawing.Pen pen = new Pen( System.Drawing.Color.White );

graphics.DrawPath( pen, graphicsPath1 );

}

What's in your graphics path?

Try starting out simple, e.g.:

System.Drawing.Pen pen = new Pen( System.Drawing.Color.White );
e.Graphics.DrawLine(pen, 0, 0, 100, 100);
pen.Dispose();


It's best to dispose drawing resources right away.

Hello Rob,

The PictureBox only executes the Paint event when its window receives a Paint event.
You can force it to redraw whenever you want by calling the method PictureBox.Refresh().
By the way, I don't recommend you to call PictureBox.Refresh() in the PictureBox.Paint event.

Regards.
