Image Recognition between 2 images vb.net Lockbits - vb.net

Question

I was in the process of using Pixel to do my search between a large image and a small image. I got that one to successfully work but am having trouble getting the lockbits version to do what I want it to do.
Fist I want to loop through the large image finding the first pixel of the smaller image inside it. Then once finding the first pixel to do a math equation to tell me what percentage of accuracy it got off it. In doing so if it meets the criteria to move my mouse to that location on the screen at the first pixel (top most left) of that small image inside the large image. Which works with a great rate of success and is extremely fast compared to GetPixel format.
Problem Cannot get location on the large image of where the beginning Pixel of the small image is and move the mouse to that location. Below is the code:
Try
Dim ifnd As Boolean = False
Dim PreviousX As Integer
Dim PreviousY As Integer
PreviousX = MousePosition.X
PreviousY = MousePosition.Y
Dim MatchCount As Integer = 0
Dim oX As Integer = 0
Dim oi As Integer = 0
Dim iX As Integer = 0
Dim iY As Integer = 0
Dim bmp_original As Bitmap
Dim ImG As Bitmap
ImG = PictureBox2.BackgroundImage
bmp_original = ImG
Dim bmp_large As Bitmap
Dim SmG As Image
SmG = PictureBox1.BackgroundImage
bmp_large = SmG
Dim bmg As Bitmap
'large image
ImG = BBt
'small image
bmg = Abt
Thread.Sleep(1000)
'large image
If BBt Is Nothing Then
Dim xbit As Bitmap = New Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height)
Dim g As Graphics = Graphics.FromImage(xbit)
BBt = xbit
g.CopyFromScreen(0, 0, 0, 0, Screen.PrimaryScreen.Bounds.Size)
g.Dispose()
Thread.Sleep(2000)
End If
'small image
PictureBox5.BackgroundImage = Abt
'large image
PictureBox6.BackgroundImage = BBt
'For value As Integer = 0 To 5
'For value As Integer = 10 To 0 Step -2
Thread.Sleep(1000)
'original image
Dim oRect As New Rectangle(0, 0, bmg.Width, bmg.Height)
Dim oBmpData As BitmapData = bmg.LockBits(oRect, ImageLockMode.ReadWrite, System.Drawing.Imaging.PixelFormat.Format24bppRgb)
Dim oPtr As IntPtr = oBmpData.Scan0
Dim oPixels(99) As Integer
Dim oMaxPix As Integer = bmg.Width + bmg.Height
Marshal.Copy(oPtr, oPixels, 0, oMaxPix)
Dim smWidth As Integer
smWidth = bmg.Width - 1
'small image
PictureBox3.BackgroundImage = bmg
'large image
Dim lRect As Rectangle = New Rectangle(0, 0, bmp_large.Width, bmp_large.Height)
Dim lBmpData As BitmapData = ImG.LockBits(lRect, ImageLockMode.ReadWrite, System.Drawing.Imaging.PixelFormat.Format24bppRgb)
Dim lPtr As IntPtr = lBmpData.Scan0
Dim PixelCount As Integer = ImG.Width * ImG.Height
Dim lPixels(PixelCount - 1) As Integer
Marshal.Copy(lPtr, lPixels, 0, PixelCount)
'large image
PictureBox4.BackgroundImage = ImG
Dim MathScore As Integer
Dim MaxScore As Integer = bmg.Height
'beginning of Marshal Loop
For i As Integer = 0 To lPixels.GetUpperBound(0)
If oPixels(0) = lPixels(i) Then
'we have a match for top left pixel - so compare the other pixels
Dim PixelsToLeft As Integer = (i Mod ImG.Width) - 1 'pixels to left of 10by10 section of large image
Dim PixelsToRight As Integer = ImG.Width - PixelsToLeft - smWidth 'pixels to right of 10by10 section of large image
Dim d As Integer = PixelsToLeft + PixelsToRight 'array distance between right edge of 10by10 section and left edge of next row
For y As Integer = 0 To 9
For x As Integer = 0 To 9
Dim oIndex As Integer = (y * 10) + x
Dim lIndex As Integer = (i + (y * (d + smWidth))) + x
If oPixels(oIndex) = lPixels(lIndex) Then
MathScore = MathScore + 1
xx = oPixels(0) + 2
yy = lPixels(i) + 3
SetCursorPos(xx, yy)
End If
Next
Next
If MathScore >= Val(MaxScore / 2.5) Then
SetCursorPos(xx, yy)
Dim percent As String
Dim myDec As Decimal
'inttemp = (intData2 * 100) / intData1
myDec = Val((MathScore * 100) / MaxScore)
myDec = FormatNumber(myDec, 0)
percent = myDec & "%"
Label16.Text = "Match Score: " & percent
Label17.Text = "Math Score: " & MathScore & " out of " & MaxScore
Me.ToolStripStatusLabel2.Text = "Completed"
Me.Button4.Enabled = True
GoTo Foundit
End If
End If
Next
PictureBox1.Image = (Abt)
PictureBox2.Image = (BBt)
ImG.UnlockBits(oBmpData)
bmg.UnlockBits(lBmpData)
Foundit:
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0)
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0)
Catch
End Try
Now if I could figure out how to get the mouse to move on the screen then I would have figured it out. Unfortunately I have been working on this for several days without any success. If you could help I would greatly appreciate it. Thank you in advance.

Answer 1

to move the mouse do this
dim a as new point
a.x = "the number you want"
a.y = "the number you want"
windows.forms.cursor.position = a
