I have tried a simple OCR program from youtube. Here, i am getting 'type expected' ERROR near Graphics. please help in this regards. I am using Visual Studio 2012.

Imports Emgu.CV
Imports Emgu.Util
Imports Emgu.CV.OCR
Imports Emgu.CV.Structure
Public Class Form1
    Dim OCRz As Tesseract = New Tesseract("tessdata", "eng", Tesseract.OcrEngineMode.OEM_DEFAULT)
    Dim pic As Bitmap = New Bitmap(270, 100)
    Dim gfx As Graphics = Graphics.FromImage(pic)



    Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
        gfx.CopyFromScreen(New Point(Me.Location.X + PictureBox1.Location.X + 4, PictureBox1.Location.Y + 30), New Point(0, 0), pic.Size)
        PictureBox1.Image = pic
        PictureBox1.Image = Nothing
    End Sub
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        OCRz.Recognize(New Image(Of Bgr, Byte)(pic))
        RichTextBox1.Text = OCRz.GetText
    End Sub

I can confirm that the proposed solution works extremely well. I have been using it for quite a while with excellent results.
