A while ago a guy here at the forum helped me to put together a program to take a photo of a specific window that had opened on the computer. I wonder if I can get this picture instead of the whole window, be just a part of the window!

You will need 2 libraries:

using System.Drawing;  
using System.Drawing.Imaging;

And to take the screenshot:

private void PrintScreen()
{  
    Bitmap printscreen = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
    Graphics graphics = Graphics.FromImage(printscreen as Image);
    graphics.CopyFromScreen(0, 0, 0, 0, printscreen.Size); //Copia a imagem da tela
    printscreen.Save(@"C:\Temp\printscreen.jpg", ImageFormat.Jpeg); //Salva a captura de tela
}

Documentations: System.Drawing.Imaging and System Drawing..

  • Copyfromscreen(0, 0, 0, 0, printscreen.Size); ?

    Yes, but if you are going to change, I recommend using pointers. Take a look therein.

  • Thank you very much, man, you helped a lot!
