Hello,

I'm scanning a JPG image file pixel by pixel and writing the results to a streamwriter (output.txt)...This part works perfectly.

I'm now trying to list the same information to a multi-line textbox (textbox1) but it only lists the last line once it completes.

I want all of the lines to list in the textbox and scroll as it scans the JPG file.

Here's my Code:

Private Sub Pixel_Button_Click(sender As System.Object, e As System.EventArgs) Handles Pixel_Button.Click
Dim PixelImage As New Bitmap(Picture1.Image, Picture1.Width, Picture1.Height)
Dim Writer As New System.IO.StreamWriter("C:\Users\Scott\Downloads\output.txt")
For i As Integer = 0 To PixelImage.Width - 1
For j As Integer = 0 To PixelImage.Height - 1
Dim pixel As Color = PixelImage.GetPixel(i, j)
Writer.WriteLine("Coordinates: " & j & "," & i & " - " & pixel.ToString)
TextBox1.Text = "Coordinates: " & j & "," & i & " - " & pixel.ToString
Next j
Next i
Writer.Close()
MessageBox.Show("Pixel Scan Completed!")
End Sub

I appreciate any help I can get.

Thanks
