I have a text file in this format

Basically I would like to read in this file line by line and separate every every field into a custom variable and then do some processing. So, I would read in the first record and put the data into these fields
date
time
ticker
sector
open
high
ETC
I started coding this using a TEST file that only had two fields name and a number
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Dim FILE_NAME As String = "C:aaple2.txt"

I got an unhandled exception on this line: mNum = objReader.ReadLine
I have been learning VB.NET and am currently having troubles retrieving data from an XML file. I'm trying to keep the code as simple as possible as I only need to select single items from an XML file, not rows of data.
The XML file contains:
<CurrentPeakUsage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://au.com.amnet.memberutils/">
<Period>

While the msgbox will contain the entire XML document, so it is loading correctly, I can't pull the single element value.
I have a program that, at present, reads a set of global variables from a text file. The program is on the client machines (around 100 clients). My problem is that when it comes to the update of the variables within the client program an error sometimes appears stating that the text file could not be read as it is already open (by one of the other machines). Currently I am cutting it down so that only 30 machines read from the single text file, although I am still going to get the error occasionally. Any ideas (apart from catching the error, and trying to read again until it works). Maybe another way to store the variables?
View 3 RepliesLets say you have a few text boxes, I know how to save the information in each box to a text file, but that creates a file for each box. Is it possible to save the contence of lots of different text boxes to 1 text file, and then when loading them it would load it all back to the right places?

View 3 Replieshow i can read multiple lines from a text file to a variable that i can process individually later. Each batch needs to be stored so that i can modify them and then recombine them into a file later.So each "group" starts with the line that begins with 5 and ends with the line that begins with 8, no if we can store the line great, if not then output to a tmp file and merge after completion is ok too.. not sure how to best handle it (hence why i am posting here)I was looking at doing with Regex but this is way over my head right now. So here is what i need to do, and below is the code that processes the groups... not sure how to read the batches in first:So from this input:

View 2 RepliesI just made my first .net website. I'm trying to use the following line of code to load a file from the current directory ( same diredtory all the web files are in). I get a error saying file does not exist
InstallFormTemp = My.Computer.FileSystem.ReadAllText("installerform.html")
I copied the file to my c drive and chnage the line to

I am writing an application that connects to a specific com port. This com port can change depending on how many physical ports are on the PC, and if other USB devices have installed com ports before this one.
I have the communication to the com port all working great, but I need to get the com port description not just the "COM#" which is all I currently get.
I found in the registry where the description is stored but am having trouble doing what I need.
In this key:
Code:
HKEY_LOCAL_MACHINESYSTEMControlSet001ControlClass{4D36E978-E325-11CE-BFC1-08002BE10318}
there is a varied number of sub keys. The are numbered 0000-NNNN depending on how many ports you have. Inside each of these keys, there are multiple values, although I am only interested in one or 2 of them.
My problem is, that I do not know how to get a list of the subkeys (the 0000-NNNN keys/folders) from the original key I posted. I have looked through a few registry tutorials, and I can view the default value in the listed key, but I could not find how to list the subkeys of the listed key.
Does anyone have any sample code they could share that shows how I can get a listing of subkeys, and then run through those subkeys checking for a specific value in one of the strings contained in the subkey?
