[RESOLVED] Txt file read from, read until?

**Arightwizard** · Oct 3rd, 2009, 05:08 PM

Hi, I'm trying to make a program that can read .mp3 data (Such as Artist, Album, Year, Track number, etc), but I need to be able to do two things that I have no clue how to do:

1. Read starting from a specified string (E.G, On one line it states:

Code:

1 3 9 1 9 2 6 ; A M G p _ i d = P         4 4 7 2 6 ; A M G t _ i d = T   1 4 3 3 1 4 5 7   TPE2      WeezerPRIV   "  WM/WMCollectionID &#197;&#184;4#&#236;5Kc [tPRIV   '  WM/WMCollectionGroupID &#197;&#184;4#&#236;5Kc [tPRIV     WM/Provider A M G   TIT2      Pork And BeansTRCK   	   89375734TCON      Alternative/PunkTCOM      Rivers CuomoTPE1      Weezer

I need to read (for track number) Starting from:

Code:

TRCK

)

2. Read until a specified string (E.G, On the previously stated line,
I need to read starting from what I said, up until

Code:

TCON

i think using Regex is the easiest way for you. Try to google it (i see it but i dont know how to write it)

Check out this thread.

Zeljko, Regex searches for patterns - not in between patterns - so I can't be helped by that.
BadgerBadger, I would prefer not to take someone's work. I only ask this small snippet from VBForums because I could not think of it myself.
Remember I asked to search in between strings, not read from mp3s with ID3 readers.
Thanks,

In that case check out a CodeBank submission made by Vectris which shows you how to get strings in-between strings without using Regex.

Right, With Regex you can find start string and end string and that givs you the middle - what you want it?
For example search for <p> start tag (paragraph) and end paragraph </p>... in the middle is you string. I see it on web when I look something similar when I need it, but then i picked up something what I can understand (i must admit that regex is preaty hevy to learn in quick maner) from this thread:

It helped me alot. I know it will help you also
