VS 2010 - Load, Read, Locate, & Copy Text In A File?
Jun 14, 2011
I'm calling a 3rd part app which 'sometimes' works in VB.NET (it's a self-hosted WCF). But sometimes the 3rd party app will hang forever, so I've added a 90-second timer to it. Problem is, how do I know if the thing timed out?
Code looks like this:
Dim MyProcess as System.Diagnostics.Process = System.Diagnostics.Process.Start(MyInfo)
MyProcess.WaitForExit(90000)
What I'd like to do is something like this
If MyProcess.ExceededTimeout Then
MyFunction = False
Else
MyFunction = True
End If

Before I begin I would like to mention that I am not a noob in VB, it's just I've never had to do anything this complex before.Basically what I want is to have a program that you can load a txt file in, have it copy key words, and paste it in a textbox so I can use it later on.So in this text file, there is a bunch of info, but I am only needing a certain part.Here is an example of a text file (actually a .dat file, but is easily read):
s t y l e T h e m e d s h y - A l p i n e V i l l a g e S e t S t y l e & h y - a v p o s t 1 H a n g 3 , V ¯s t y l e T h e m e d s h y - A l p i n e V i l l a g e S e t S t y l e , y - a v p o s t 1 H

I'm trying to read and load the content from the attached text file to a arraylist with the code bellow.
but what is happening is that not all the lines from the text file are loaded in to the arraylist, the reading jumps from one line to other in the text file.
Dim FILE_NAME As String = ((My.Application.Info.DirectoryPath).Substring(0, (My.Application.Info.DirectoryPath).LastIndexOf(""))) & " est.txt"
Dim lista_barras As New ArrayList
Dim lista_barras_esp As New ArrayList

I've written several loading programs in the past, but never with VB.NET, always VB 6.0.I need to load a text file (actually, there are 24 per day), into our Oracle database. I have the file open and I can read it no problem, the question is, what's the best way to load it?
In the past, I've always read a record into an array and then passed the array as a variable into the Oracle statement in my code - basically loading one record at a time. I'm wondering if there's a better way to do this, specifically in the new world of VB.NET. Is there a way to load everything at once, rather than running an INSERT statement for every record individually?

I'm trying to do is read a text file from a certain line to the end of the file. For example, say the text file is:
Hello
Everyone
My Name
Is Tyler
I would like to be your friend. Would you be mine? I like dogs, cats, and basically any animal. I play the tuba and am in a band at college. I go to UMass. Do u like UMass?
(none of the above info is true FYI)
My code would look like this:
Dim hello as string= io.file.readlines(c:/text.txt)(0)
Dim everyone as string= io.file.readlines(c:/text.txt)(1)
Dim myname as string= io.file.readlines(c:/text.txt)(2)
Dim istyler as string= io.file.readlines(c:/text.txt)(3)
But say I wanted it to read from line 4 to the end of the file? The entire description I would want to save as one variable. How would I do this?

I have a notepad txt file that has two columns of data. Vb reads data having one blank space (this is in column one) but ignores any other data beyond two blank spaces. in addition to being able to read the second column, I want to store the data thats in the column 2 in a separate string.

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?

How would I go about reading a textfile, finding values and using the values in the program?Now I want the program to read the text file, find [1], use the first line after [1] as value for a variable, and the second line as value for another variable. After that I will run some code with the values and then do the same thing again for [2] etc.

My text file is a settings file and I know I will be adding more to it in the future, right now it reads "autoplay=false;mintray=false;"I am currently using probably the most inefficient way to check both of those settings:
if contents = "autoplay=false;mintray=false;" then
elseif contents = "autoplay=false;mintray=true;" then
elseif contents = "autoplay=true;mintray=false;" true
elseif contents = "autoplay=true;mintray=true;"
endif
How can I read the file, find each word from the equals sign to the semicolon, and store each of them in a variable identified by the text before the equals sign? Something like this:
contents = "autoplay=false;mintray=false;"
autoplay = "false"
mintray = "false"
Also, how can I edit the settings in the text file without having to overwrite everything every time I save to it? For instance; finding mintray in the text file, and changing mintray to true instead of overwriting the file with "autoplay=false;mintray=true;".
This is my current

I am returning to VB building, first time since HighSchool. I am creating a program that has many fields of data that you type into. When you click Generate Button it then writes all that data a .txt file and opens it in notepad.
From that point you copy everything in notepad and paste it into a ConnectWise HelpDesk Ticket.
My goal is to automatically get the data when clicking Generate to populate into the Clipboard, or let it write to the .txt file and then copy all the data from the .txt file into the clipboard. So all you have to do is Ctrl + V after Clicking "Generate"

I'm using vb.net 1.1 to develop the program. I got text files that contain test result from a machine, like below.
T1 1.24535 2.56335 2.43253 1.24538 2.55619 4.35243
T2 1.42542 1.63728 3.57295 4.59275 1.57320 2.72057
T3 5.12857 2.45375 6.38593 2.58375 3.57259 3.57204
I need to check the test result with the data from database, to find out which test result is failed. If there is a fail test result, I will show an alert to the operator and stop the checking process. Until the operator close the alert, then the checking process will continue from the last read point.
