Let's say my match.Index returns 100 000 as the location for the first string I was searching for. How do I then resume my new search at this point?

Okay, so I've been looking on the web for a way to read only ONE line out of a text file. Recently I've gotten by by creating separate text file for each line (such as a text file named, "Username", another named "Password", instead of creating a single text file with both the user name and password.) Now I am faced with having to do this. I want a quick and easy way, VB won't let me do open file as input #1 for some reason. I just need the second line of text out of this text file. What is the quickest and easiest (and painless) way of doing this?

I want to be able to read ONLY the link from the file.. In the first file above it would be after the "File1=" text in the file.. And in the other file it should be whats written after the "<ref href="" part..
And as you see in the second file there are three links, so to start with it should only read the first line, maybe later i could make a selection window popup or something..

I am reading a csv file in VB.net and saving the line to a SQL database. At a later point in my code, the SQL line is retrieved in the application, and the Split function is used to get 'field' values. The Split is done taking comma as the separator. The application processes many other files (including excel), and the split function is used for all of them. The problem I am now facing is that one of the csv files I read, has a field value that starts with " followed by multiple values separated by a comma and ends with another ". The normal reading of the csv file results in each of those single field values is taken to be a separate value.
An example line is: Elker,MissB,"Bus, Taxi, Train, Ferry, Parking, Toll",800253 Where there should only be separated to 4 columns, they get separated to 9 columns instead. What I want to do is replaced the commas after 'Bus' and until 'Toll' with a '?' instead. I have tried using Replace, including the overloaded one with starting position, but it ends up replacing ALL the commas in the line with '?'
Attempt 1: If vstrLine(intStartPos) = "," Then strRetVal = Replace(vstrLine(intStartPos), ",", "?") end if Where vstrLine is Elker,MissB,"Bus, Taxi, Train, Ferry, Parking, Toll",800253 and intStartPos is the first instance of a comma after the " It returns only the '?' and not the string with 1 comma replaced by '?'
Attempt 2: If vstrLine(intStartPos) = "," Then strRetVal = Replace(vstrLine, ",", "?", intStartPos) end if It returns a string with all commas replaced with '?'

dealing with a C++-DLL I get a pointer (thepointer as IntPtr) to an array as return value. The pointer indicates the first bit in memory where an array of UShorts is stored. I know the size (thesize as Integer) of the array and want to read it. Marshal.Copy does not support UShort. As the values stored in the named array can exceed 32767 working with Shorts will not do. I tried to work with structures but the array of UShorts in my structure is not populated using: [Code] Does anyone have an idea how to get the array of UShorts out of the pointer position or see a mistake in my code?
