Public Class Form1
Dim img As Bitmap
Dim WithEvents pd As PrintDocument
'Returns the Form as a bitmap
Function CaptureForm1() As Bitmap
Dim g1 As Graphics = Me.CreateGraphics()
Dim MyImage = New Bitmap(Me.ClientRectangle.Width, (Me.ClientRectangle.Height), g1)
Dim g2 As Graphics = Graphics.FromImage(MyImage)
Dim dc1 As IntPtr = g1.GetHdc()
Dim dc2 As IntPtr = g2.GetHdc()
BitBlt(dc2, 0, 0, Me.ClientRectangle.Width, (Me.ClientRectangle.Height), dc1, 0, 0, 13369376)
g1.ReleaseHdc(dc1)
g2.ReleaseHdc(dc2)
'saves image to
c drive just, u can comment it also
'MyImage.Save("c:\abc.bmp")
Return MyImage
