To start, this is not another thread asking for help because I can't get ImageSearch to work at all.

Script Use: With Oracle Applications in use in a manufacturing plant, being used to log transfers of subassemblies along a production line.

Script Concept: Extrapolate necessary key hits based off of minimal user input. Look for visual cues on the screen to verify that Oracle Applications is responding in the desired fashion--if not, cancel the operations.

My basic method is to hit several keys to do something in Oracle Applications, and then look for the desired response. I use a looped ImageSearch over 10 seconds that looks for an image fragment. As soon as the desired image fragment is found (for example, the window title of a message box that should pop up) the script proceeds.

Since the Oracle Applications I have uses a Java interface, everything inside of it is transparent to Autohotkey--it's all one window. There's no other way to detect what's going on inside the program besides ImageSearch, in case anyone wonders. (Or if there is, it's waaay over my head.)

So, what's the problem?

Well, the script works 100% beautifully the first time. I enter my data into the custom Autohotkey GUI I made, my "Log Job" button triggers a subroutine (Sub_LogJob) that calls a custom function (F_CheckLog) I have. The custom function runs all the way through successfully, using 10 or so instances of ImageSearch to verify things are dandy along the way. Everything goes fine in Oracle Applications and in the end I get a MsgBox saying "Job Successfully Logged."

The problem is that when I call up the GUI again, enter data and try to run it, it doesn't work a second time.
The "Log Job" button triggers the Sub_LogJob subroutine.
The Sub_LogJob subroutine calls the F_CheckLog function.
But as soon as the F_CheckLog function tries to use ImageSearch, I get an ErrorLevel 2, meaning that Autohotkey couldn't search for my image. This is usually some sort of formatting problem, like leaving the ".bmp" off of the image name. But that can't be, because my script just used that image successfully 30 seconds ago.

Why is this happening?

Heh, can't edit my own post because I'm a guest.

One more thing, this is the Error Log I get after trying to use the script a second time.

You want help with 450 lines of code? Are you nuts?

Say hello to a few troubleshooting helpers

http://www.autohotkey.com/docs/Variables.htm#prop
A_LineNumber
A_LineFile

http://www.autohotkey.com/docs/commands/ListLines.htm
http://www.autohotkey.com/docs/commands/ListVars.htm

You can use these to stop the process and see what the variable values are.
Be forwarned that A_index (and other) automatic variables don't show up in ListaVars, copy them to a user_defined varaible to see their value.

I use msgbox to pause the script so I can read the "ListVars" results.

Well, I didn't expect anyone to look through all of my code, I felt more obliged to provide it.

I've been doing more testing on and off throughout the day. The script works 100% fine, 5% of the time.

More data: I used the ListVars command with a MsgBox and here's the dump:

I'm pretty much at a loss except to suggest another level of debug.
Sorry for the contrived example.

I suggest adding these variables if possible, they need to be inline otherwise they will refer to "save_listvar"

And make sure you record the results for ALL imagesearch erorlevels when it passes and when it fails
B_ThisLabel:=A_ThisLabel
B_ThisFunc:=A_ThisFunc
B_LineFile:=A_LineFile
B_LineNumber:=A_LineNumber

I tried what you said and it didn't work 100% perfectly, for whatever reason the save_listvar variable wasn't filled with the listvar contents so the text file was basically empty. However, I did open up the ListVar box and use a MsgBox to pause it. I also looked at the recently executed lines.

The strange thing is that everything is doing exactly what I tell it to. The correct function is being called, it is executing ImageSearch using the correct variable that has the correct file name in it (evidenced by the fact that using ImageSearch with the same filename, elsewhere, works fine). The simple fact is that ImageSearch is failing, and I don't know why.

But--a breakthrough! First I tried relaying the GoSub:

Beats the heck out of me.
BTW, that was figuarative language, don't hit me.

I'm glad for your success.
