I haven't been able to find a post on this problem although I don't doubt it's already in another post. If so, just direct me there.

I would like to search an area for a pixel. When it shows up I would like to mouseclick that pixel. Sometimes that pixel will be there and sometimes not.
Here's my current code


Of course, right now, when the pixel is not there it'll throw up a message box. How do I keep a persistent "watch" out for the pixel as to send the mouseclick as soon as it pops up?

You can use a loop or SetTimer for that.

If I'm running a loop, how do I exit it if a particular window pops up

current code


It's god awful code, but anyways. Once I click the image for save.png, that brings up an external webpage (which it's suppose to do). Once this webapge exists I want the script to stop, pause or kill.

http://www.autohotkey.com/docs/commands/Loop.htm

Perform a series of commands repeatedly: either the specified number of times or until break is encountered.

A common use of this command is an infinite loop that uses the break command somewhere in the loop's body to determine when to stop the loop.

I tried this, but the loop continues on even though the window has popped up and exists.


what am I doing wrong?

All you needed to do was replace "???" with "Break". But you added a whole nother loop.

I tried that one already and it ends up Breaking everytime, even if the window isn't there? what gives?

Is a window that matches that pattern open on your machine?
By 'open' I don't mean, active and being viewed. It could be minimized.

Actually, here's the code, I just omited some lines that I thought were irrelavent.


When I run this script, a message box may appear when I hit the test.png image. If so, I use WinKill to get rid of it. But the second WinExist in the code comes after that window is already gone. And yet it still puts a break in there.

This is my 4th post to you in approximately 9 hours, seemingly on the same subject.

My first post was a reference to the answer you needed.
Through two other posts I have attempted to help, but I have failed to help solve your problem.

Now I read this:
I fear that I can't guide you or help you because you pick and choose what to share.
You omit important facts, eg. that a window pops up and you kill it and that another may come as well.

Perhaps the task is too complex for Ahk, or for me, or for you; I don't know. I can't judge because you decide what to share.

If you want my continued help I need the following: A better description of what you are really facing.

Your code shows you find and click on an image, find & click on a pixel , then find and click on an image once again. Then your loop repeats.
Somewhere in there you get other windows and you kill one, but want to stop looping when the other window shows. Why do you need loop as written?

Leef_Me,
my apologies. Sometimes I just think everyone is privy to the same track that my brain is going on. I apologize for being unclear.

So I'll give you a run down and thinking behind my script.

1. When I click the image test.png, it refreshes a frame in another part of the webpage.
2. if the the frame contains no data, a message box pops up saying somethinng to the effect of "No data available"
3. I then kill that message box(I guess at this point, I could have it start back at the beggining of the loop).
4. To check if data is in the frame I have to do a pixelsearch( it sounds weird but it's a secure work webapge that has a frame that is loaded by AJAX. through all my ahk research and trial and error, I've been unable to scrape any text off the frame. I can do a pixelsearch though to see if text is there. It's primitive, but it works.)
5.So after hitting the test.png, which refreshes the frame, if data is in the frame, no message box will come up. Pixelsearch then scans the frame and clicks the top row in the frame.
6. By clicking the top row in this frame, it illuminates a 2cd image on the webpage. It then searches for that image to click.
7. By clicking that final image save.png, another window pops up asking me if I really want to save. This is why I want the break in the loop. Once this question box comes up I don't want the loop to scan anymore.


It really is a screwy loop script, but it's the only way to automate to check for the data in this frame and then click the save.png image to save it.
I know it hard to paint a picture when you don't know what the website is. The best way I can describe it is that it's like a JAVA applet. So while you can mouseclick buttons, you can't really scape the visual data off.
I hope I'm not frustrating you too much. If so, just let this post drift down the forum stream.

Put the IfWinExist at the top so it will break the loop before it proceeds with the check:
