Move mouse to color??

hi im trying to make a promgram that will follow certian colors on my screen with the mouse is there anyway i can do that

Are you looking to make this program to follow a color on the programs window, or are you looking to use the whole screen....
I can think of one way to do it for the whole screen but it won't be fast...
- have a loop where it captures the whole screen to an image,
-search for the color your looking for
-get the coordnates of the pixel
-then set the mouse to that point on the screen.....

++++Some more detail of what you actually want to follow would help out...++

I am just curious what this is for.....

i need to search the hole screen and it doesnt need to be fast

and its for like a game lol

and if u can send me code ill be very happy

Here is Code to capture the whole screen...
This works for vb.net 2005....should work for vb.net 2003

VB Code:

Public Class CaptureScreen
    Private Declare Function CreateDC Lib "gdi32" Alias "CreateDCA" (ByVal lpDriverName As String, ByVal lpDeviceName As String, ByVal lpOutput As String, ByVal lpInitData As String) As Integer
 
    Private Declare Function CreateCompatibleDC Lib "GDI32" (ByVal hDC As Integer) As Integer
 
    Private Declare Function CreateCompatibleBitmap Lib "GDI32" (ByVal hDC As Integer, ByVal nWidth As Integer, ByVal nHeight As Integer) As Integer
 
    Private Declare Function GetDeviceCaps Lib "gdi32" Alias "GetDeviceCaps" (ByVal hdc As Integer, ByVal nIndex As Integer) As Integer
 
    Private Declare Function SelectObject Lib "GDI32" (ByVal hDC As Integer, ByVal hObject As Integer) As Integer
 
    Private Declare Function BitBlt Lib "GDI32" (ByVal srchDC As Integer, ByVal srcX As Integer, ByVal srcY As Integer, ByVal srcW As Integer, ByVal srcH As Integer, ByVal desthDC As Integer, ByVal destX As Integer, ByVal destY As Integer, ByVal op As Integer) As Integer
 
    Private Declare Function DeleteDC Lib "GDI32" (ByVal hDC As Integer) As Integer
 
    Private Declare Function DeleteObject Lib "GDI32" (ByVal hObj As Integer) As Integer
 
    Const SRCCOPY As Integer = &HCC0020
 
 
 
 
    Public Shared Function GetScreen()
        Dim oBackground As Bitmap
        Dim FW, FH As Integer
        Dim hSDC, hMDC As Integer
        Dim hBMP, hBMPOld As Integer
        Dim r As Integer
 
        hSDC = CreateDC("DISPLAY", "", "", "")
        hMDC = CreateCompatibleDC(hSDC)
 
        FW = GetDeviceCaps(hSDC, 8)
        FH = GetDeviceCaps(hSDC, 10)
 
        hBMP = CreateCompatibleBitmap(hSDC, FW, FH)
 
        hBMPOld = SelectObject(hMDC, hBMP)
        r = BitBlt(hMDC, 0, 0, FW, FH, hSDC, 0, 0, 13369376)
        hBMP = SelectObject(hMDC, hBMPOld)
 
        r = DeleteDC(hSDC)
        r = DeleteDC(hMDC)
 
        oBackground = Image.FromHbitmap(New IntPtr(hBMP))
        DeleteObject(hBMP)
        Return oBackground
    End Function
 
End Class

Here is how you would go about capturing the screen with the code above...

This is the code you would put in the event to call the find color function...
(it translates the color to ole integer...)

VB Code:

Dim SearchColor As Integer = Drawing.ColorTranslator.ToOle(Color.Black)
FindColor(SearchColor)

HERE IS THE FINDCOLOR FUNCTION::::
It sets the mouse to the first pixel it finds with that color....

VB Code:

Private Sub FindColor(ByVal MyColor As Integer)
 
        Dim Spic As Bitmap
        Spic = CaptureScreen.GetScreen()
        'capture the screen to a image
 
        For i As Integer = 0 To Spic.Width - 1
            For k As Integer = 0 To Spic.Height - 1
                'itterate through each pixel
                If ColorTranslator.ToOle(Spic.GetPixel(i, k)) = MyColor Then
                    'if the pixel is the same color we are looking for
                    Windows.Forms.Cursor.Position = New Point(i, k)
                    'exit the routine to save time
                    Exit Sub 'maybe get rid of this line if you want to other pixels too
 
                End If
            Next
        Next
    End Sub

So just add the "ScreenCapture" class to your project
Use the findcolor function to set the mouse to that pixel

Good Luck

EDIT: Fixed my question. tyhnx tho

Hey wait, now thinking about it? Can i make it search inside a range? or box area? of cordinates maybe? Like 100, 100 to 500,500 then search.

Because i would love for it to be a furnction like:

FindColor(SearchColor, STARTX, STARTY, ENDX, ENDY)

So it can if STARTX = 100 and STARTY = 100 and ENDX = 500 and ENDY = 500 so it would search inside a "box" or range inside 100,100 to 500,500 for that specific "SearchColor"?


Can u help give me that code plz? That would b aweesommee:D

I could never get this to work with vb, got it to work in java. But there is a program called AutoHotKey that does that exact thing. finds a color from point to point works very well.
