If you want the code to do a print screen, capture just the form, just the client area of the form let me know and I will post it.

Here's something off the top of my head: (It'll require some API declarations from the API viewer.)

deskWnd = GetDesktopWindow
deskDC = GetDC(deskWnd)
BitBlt Picture1.hDC, 0, 0, Screen.Width \ Screen.TwipsPerPixelX, Screen.Height \ TwipsPerPixelY, deskDC, 0, 0, vbSrcCopy
ReleaseDC deskWnd, deskDC
deskDC = 0
deskWnd = 0

I'll make a full ver of the code when I get home.

Descirption: Capture an image of a form in a PictureBox (2K)

Hi short_fat_n_black ,
   
To mimic the printscreen / take a snapshot of desktop:

http://www.mvps.org/vbnet/code/bitmap/printscreen.htm 

Here is another version that Calling the Windows PrintScreen Function Using keybd_event:

Option Explicit

Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags
As Long, ByVal dwExtraInfo As Long)

Private Const TheScreen = 0
Private Const TheForm = 1

Private Sub Command1_Click()
 'call the Windows keybd_event sub, passing the built-in
 'VB keyboard constant vbKeySnapshot (44) to the sub.

 'The four parameters for keybd_event are:
 'BYTE bVk           'virtual-key code
 'BYTE bScan         'hardware scan code
 'DWORD dwFlags      'flags specifying various function options
 'DWORD dwExtraInfo  'additional data associated with keystroke

 'The bScan parameter value determines what
 'to copy... passing 0 (TheScreen) copies
 'the screen, passing 1 (TheForm) copies the
 'active form.
  keybd_event vbKeySnapshot, TheForm, 0&, 0&
 
 'pause to let Windows update the clipboard
  DoEvents
 
 'retrieve the clipboard bitmap to the control (vbCFBitmap = 2)
  Image1.Picture = Clipboard.GetData(vbCFBitmap)

End Sub
