Hi.

just got .net game programming with DirectX9 and trying to do a simple bit of code drawing a rectangle in a picture box. I've got the following code in the forms paint event.

Dim graph As Graphics
        Dim rectSquare As Rectangle
        Dim graphPath As Drawing2D.GraphicsPath
        Dim brushSquare As Drawing2D.PathGradientBrush

        graph = Graphics.FromHwnd(PictureBox1.Handle)

        'create a path consisting of one rectangle
        graphPath = New Drawing2D.GraphicsPath()
        rectSquare = New Rectangle(10, 20, 23, 27)
        graphPath.AddRectangle(rectSquare)
        brushSquare = New Drawing2D.PathGradientBrush(graphPath)
        brushSquare.CenterColor = Color.FromArgb(255, 0, 255, 0)
        brushSquare.SurroundColors = New Color() {Color.FromArgb(255, 0, 0, 255)}

        'create the rectangle from the path
        graph.FillPath(brushSquare, graphPath)

if you're quick you can see the rectangle but then the picture box is draw over it! I've tried putting this code in the paint event of the picture box but to no avail.

Please help! Simple example and I can't get it to work!!!

Hi nswan

I've got that book too, very nice especially the tiled game "River Plan.NET"

If you look in the book the code your using isn't meant to go in a paint event just put it in a Public Sub Show and call it. Have a look at the code for that bit on the CD and you'll see what i mean.
