help parsing a string

[kebo]

I have this text file that I need to parse the number the is bolded

	J:\	Volume Number: -1070353568

Current number of systems: 1

the file will always have "C:\ Volume Number:" appearing only once right before the number I need. Can I split a string based on another string? or what functions can I use that will lead to an efficient way to do this? I don't need the code I can write that if I know the best functions to use to get the job done.
thanks

Probably Regular Expressions will be the best. I have only used it twice and it seems to be very flexiable in what it can do.
Is your app outputting the file?

Yeah it is, then another app I'm writting parses it.
I'll look at regular expression and see how to use it (them)
thanks

since your app writes the file then wouldnt it be easier to write it out in a easier format for you to read in? or maybe another file
for parsing only and not the user?

[kebo]

yeah it would be, but the format is already in use by others and would be a terrible pain to change everything else. You know, it's the boring details...it always comes down to details.

I thought about that too, but if you were to write out a duplicate file customized to your parsing needs then that will possibly
save you some headaches.

unfortunatley that create other headaches

I have it working using instr like this (with a small output file mod)

's= OutputFile.txt
                Const rConst As String = "C:\ Volume Number:"
                Dim iStart As Integer = InStr(s, rConst)
 
                istart += rConst.Length
                Dim iEnd As Integer = s.IndexOf(vbCrLf, iStart)
                Dim myNum As String = s.Substring(iStart, iEnd - iStart).Trim

but I would rather use a RegEx but this doesn't work

Const rConst As String = "C:\ Volume Number:"
                Dim r As New System.Text.RegularExpressions.Regex(rConst)
                Dim iStart As Integer = r.Match(s).Index

iStart is always 0. How come? I suspect I'm not using RegEX correctly

thanks
for the help Rob

There are codes that make up your search string. It looks like 1337.

Look here, I think this will here for the expression needed.
