************** Exception Text **************
System.ComponentModel.Win32Exception: The handle is invalid
   at System.Drawing.Graphics.CopyFromScreen(Int32 sourceX, Int32 sourceY, Int32 destinationX, Int32 destinationY, Size blockRegionSize, CopyPixelOperation copyPixelOperation)
   at System.Drawing.Graphics.CopyFromScreen(Int32 sourceX, Int32 sourceY, Int32 destinationX, Int32 destinationY, Size blockRegionSize)
   at Sales.Form1.timer4_Tick(Object sender, EventArgs e)
   at System.Windows.Forms.Timer.OnTick(EventArgs e)
   at System.Windows.Forms.Timer.TimerNativeWindow.WndProc(Message& m)
this is my code as following :
under timer tick event problem happen in screen shoot
the proplem in these lines
Bitmap bitmap = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
Graphics graphics = Graphics.FromImage(bitmap as Image);
graphics.CopyFromScreen(0, 0, 0, 0, bitmap.Size);
bitmap.Save("C:\\screenshot.jpeg", System.Drawing.Imaging.ImageFormat.Jpeg);
if i put these lines under button event work ok
but if i but these lines under timer make problem and give me exception above why
this code of screenshoot work in my windows xp but when i put in windows server 2003 it give me error in screenshoot under timer event
