Tips & Tricks:

Using the System.Drawing.Bitmap class, you can create whatever pattern you desire.

Sample Code (in VB):

<System.Runtime.InteropServices.DllImport("gdi32.dll")> _
Public Function CreatePatternBrush(ByVal hbmp As IntPtr) As IntPtr
End Function

Dim gBrush As IntPtr
Dim bB As New Bitmap(Width, Height)
Dim drawingArea As Graphics = Graphics.FromImage(bB)
Dim lGB As New Drawing2D.LinearGradientBrush(drawingArea.VisibleClipBounds, Color.Yellow, _
        Color.Orange, Drawing2D.LinearGradientMode.Vertical)

drawingArea.FillRectangle(lGB, drawingArea.VisibleClipBounds)
gBrush = CreatePatternBrush(bB.GetHbitmap)
