Multiple instances of GUI using AutoIt script

[Krishna]

Dear Friends,

Few days back i started using AutoIt and really wondering this is very good tool and it is for free. Thanks to AutiIt team.

I developed an AutoIt script (Converter.au3) which simple invokes a GUI application then it selects say File->convert, then access edit boxes, list box and items, buttons etc. It is perfectly working fine. Basically the GUI application selects a set of files from a directory and converts into another format.

Now if i run the autoit script 2 times simultaneously none of the instance will work properly .

1) some times only first main window (for both the Converter.a3u instances) will display and nothing happens further.

2) some times an error - _MemInit:Invalid Window Handle is popped up.

My question (requirement) is i need to simultaneously invoke multiple instances of Convert.au3 script. Will there will be clashes of windows displayed by different .a3u scripts. Is there a way to deal with a GUI instanace and its sub windows by a particular instance of Convert.au3 which has invoked the GUI originally.

Please give me ideas or point to some examples or documentation.

Thanks in adavance .

Regards,

Krishna

Would you mind showing some code. so we can get a sense of what is going on.

Are you using titles? You should probably be using handles. Handles are unique to a window where titles will not be. So if you have more than one window with the same title the script may hit the wrong window. I understand It would find the first one via the Z order

Hello Picea,

Thank you very much your response. I have copied my script below. As you pointed out i am using the title of the windos to access it and its controls. I shall try with handles. After going thru the below script if you have any suggestions please let me know.
