Can I check if two or more of a window class exist?

8 posts in this topic

I know I can use WinExist to check if a class of window exists, but it just returns true or false. I would like to know if I have 2 or more of a window open, is this possible?
Many thanks!

I would think that you could do this with WinList.

WinList and and look at the [0][0] element of the returned array to see how many windows match.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Sorry I should have been clearer, I need to compare the windows by class, not by title.

You definitely should read the help file for WinList, paying close attention to the description of the title parameter.

Then use a Advanced Window Description:

Advanced Window Descriptions

A special description can be used as the window title parameter. This description can be used to identify a window by the following properties:

  • TITLE - Window title
  • CLASS - The internal window classname
  • REGEXPTITLE - Window title using a regular expression (if the regular expression is wrong @error will be set to 2)
  • REGEXPCLASS - Window classname using a regular expression (if the regular expression is wrong @error will be set to 2)
  • LAST - Last window used in a previous Windows AutoIt Function (see Windows Management Functions)
  • ACTIVE - Currently active window
  • X \ Y \ W \ H - The position and size of a window
  • INSTANCE - The 1-based instance when all given properties match

One or more properties are used in the title parameter of a window command in the format:
