System.Drawing.Bitmap image = AForge.Imaging.Image.Clone(imageX, System.Drawing.Imaging.PixelFormat.Format24bppRgb);
tessnet2.Tesseract ocr = new tessnet2.Tesseract();

    TextBox1.Text = TextBox1.Text + word.Text + Environment.NewLine;
}

The problem is that you need Full Trust on server to put it to work, because your application will execute a dos program (.exe extension). Anyway, fulltrust is not applicable because it lacks security. I'm trying to implement Partial Trust, but without luck.
