compare images

[blater]

hi all i got a question, i tried lots of things but i cant find any answers. how can i compare a picture in a picture box with something on the screen at given coordinates, im looking for something like this:

Option Explicit
 
Public Sub CompareIMG()
Dim intX As Integer
Dim intY As Integer
 
Dim blnMatch As Boolean     'True if pictures match
 
    If intX > 200 Then      'Check within given coordinates
        intX = 0
        intY = intY + 1
    Else
        Do Until blnMatch = True
            'Here is what i dont get, i hope it will be short like this:
            Compare picImage With (intX, intY), blnMatch
            
            intX = intX + 1
        Loop
    End If
        
End Sub

but it will probably will be very different
I hope anyone knows how to do something like this

Bye, Koen
