I am looking for some information on getting the colour of each pixel in a picture. The ide is to get the colour and then have my program draw a line along that colour itself. For example. If i have a black square on a white background, I want the software to be able the draw lines on the four edges of the black square, Is this possible?

Another little problem.I have a form with a control (Picturebox or perhaps flash) which uses graphic hotspots instead of controls with handles so when the control receives a mouseclick, it does different things depending on the coordinates of the click.I can obtain the handle for the main control and can see where the hotspots are as they look like buttons and set a point to that location.How can I send a mouseclick (WM_Mousedown?) to the precise point on the control?If I'm not mistaken, using Sendmessage with BM_Click would tell the control it was clicked but without coordinates.I'm trying to do this using Visual Basic from Visual Studio 2008

Now I wanna make an functions that find the a pixel with the matching color I put in as RGB in 3 textboxes 1 for R etc.
Basically what I want to do is create a program that every now and then (maybe 10 minutes) switches between either, all the windows currently open, or a selection of all the windows currently open, then checks the colour of a location on the screen. At the moment I have the program checking the colour at a specific coordinate, so that's all good. The problem I have now is how to switch between windows.
I've thought up a few ways to do this. The windows that I care about checking all have the same name, the same process class, but different process IDs. I already managed to stick all the process IDs into an array of integers hoping that I could use them but I don't have a clue how to bring a window to front using just the process ID. So the first method would work if I could figure out a way to do that.
My second idea, which is a pretty rubbish way of doing it, would be to simply simulate pressing Alt+Tab however many times to change between windows.
How do i find the cursor coordinates on the screen in VB 2005 code?
"label1.Text = e.Location.X" Only gives you the coordinates in the program window itself, i want it to be displayed in a label/textbox in relation to the whole screen.

is there a way of getting the screen coordinates of individual cells on an open Excel sheet, what I want to ultimately do is pass in a cell range say, "A5" into a function and watch the mouse cursor move slowly to that cell. I know this might seem a weird request. I already have a mouse move function but that accepts the x/y coords in pixel terms where excel using .TOP and .LEFT give an entirely different format?
