Not being a regexp man I need some help.
What would the StringRegExp expression be to match "blah.txt - Notepad" but wouldn't match "Untitled - Notepad".
(I know it's a trival example, but I'm, erm, experimenting with something...)
Need help with regexp

Uhhh... wow. Thats kind of hard. I don't claim to be an expert on regular expressions or anything so I may be missing something obvious, but... wow, thats kind of hard. It seems to me like there should be some way to negate a group. For example, this would match (if it worked): "(^Untitled) - Notepad". That would say "match anything but Untitled". However, thats not implemented and I'm not entirely sure if it should be.

What about:
"[.]txt - Notepad"
This would match the .txt at the end of the file name. If you want to match any extension how about "[.].*- Notepad"?
"[.]txt - Notepad"

But what happens on no extension? File names don't have to have an extension, after all.

In classic regexps you'd use something like:
/\w[.]w{2,3} - Notepad/
...to insure that before the " - Notepad" there was a file name of at least one character, a dot and a one-or-two character extension. If it's a concern that the party might have extensions hidden then the only thing I know that you could do is verify that the title isn't "Untitled - Notepad"...

Yes yes yes, there it was. Youth must go, ah yes. But youth is only being in a way like it might be an animal. No, it is not just being an animal so much as being like one of these malenky toys you viddy being sold in the streets, like little chellovecks made out of tin and with a spring inside and then a winding handle on the outside and you wind it up grrr grrr grrr and off it itties, like walking, O my brothers. But it itties in a straight line and bangs straight into things bang bang and it cannot help what it is doing. Being young is like being like one of these malenky machines.

Ok ok. I didn't really want to get into details I just wanted something simple that I could test with.
Opt("WinTitleMatchMode", 4) WinWaitActive("regexp=[.].*- Notepad")

@Jon:
I have been thinking about RegExp and window title matching before.
I have read several times that a regular expression search will use more resources than any other function.
I'm wondering if StringRegExp can return within 250ms.
Because if the window is closed during the process strange things would happen (?)
Edit:
I just saw you added that in. I will test it out now.
