I am trying to make a program that scans the pixels in the screen for certain colors and if it finds it sets the mouse location to that spot. Now i need your help to see if something like this is possible with vb and if it is possible point me into the right direction.
I don't have Visual Studio 2008 but I have Visual Studio 2005. In 2005 if you go to New Project then Other Project Types. You should see several setup projects including Setup Wizard.
Express editions do not have this feature. You have to use ClickOnce or copy all required files to the computer that has the correct Net version.
Here's something to try. This code is provided "AS IS" :twisted:
I created an invisible, full screen size form. With a timer control, I trigger the "search for the pixel" action
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
' Create an invisible form with a timer control on it
Me.FormBorderStyle = Windows.Forms.FormBorderStyle.None
Me.WindowState = FormWindowState.Maximized
Me.Opacity = 0
Timer1.Interval = 500
then I capture tick event and disable timer control
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
' Do scanning
Dim x As Integer
Dim y As Integer
Dim ScreenX As Integer
Dim ScreenY As Integer
Dim g As Graphics
Dim Img As Bitmap
' Get screen size
ScreenX = My.Computer.Screen.Bounds.Width
ScreenY = My.Computer.Screen.Bounds.Height
' Create a bitmap of the screen
g = Graphics.FromHwnd(Me.Handle)
g.CopyFromScreen(0, 0, ScreenX - 1, ScreenY - 1, New Size(ScreenX, ScreenY))
Img = New Bitmap(ScreenX, ScreenY, g)
' Loop the "screen"
For x = 0 To ScreenX - 1
For y = 0 To ScreenY - 1
' I searched for a hard-coded ARGB color (0, 0, 0, 0) i.e. black
If Img.GetPixel(x, y) = Color.FromArgb(0, 0, 0, 0) Then
' Dispose graphics
' Move the mouse
Cursor.Position = New Point(x, y)
Instead of simple exit, you may restart timer, change the color you're looking for etc.
This may be done in a simpler way and like I said, I don't guarantee that this works (in every situation).
Your question was titled "...Changing Pixel Color" but you asked for the code to move the mouse cursor.
