Need help with regexp

[Jon]

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...)

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"?

[Valik]

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"...

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.
