VS 2008 : Read And Load The Content From The Attached Text File To A Arraylist?
Jul 14, 2011
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
[code]....

I would like to know if there is a quicker way to load a text file into a listbox/arraylist than this:
Code:
Dim fileList as New ArrayList
Dim fileReader As New System.IO.StreamReader("textfile.txt")
Do While fileReader.Peek() <> -1
[Code].....
If I need to load several text files into different arraylists, especially if the textfiles have a lot of lines, this process is very slow. Too slow for my current app to work smoothly, actually.
So, is there any faster ways to load a text file into an arraylist? Or if there isn't, is there some quick way to easily access and change data that is on a particular line in a textbox, so that I don't have to load the text file into an arraylist?

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):

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

get the whole and same content of any file i uploaded, for my editing purposes in my editor w/c retrieves file from the database. i.e of files are ".doc and .txt"and by the way what i meant by same content is the whole same appearance of my .doc or .txt file i.e "if the text is bold, forecolor is red and etc.."
i successfully established a file upload and a function to store it in a database... but what i'm missing is the whole and same content of the file.

I am building a Windows Desktop software that will respond to SMS request and sending a SMS as reply automatically.
The software is ready and working just fine but it works only and only with Nokia Mobiles and the prerequisite is that Nokia's PC Suit has to be installed first before my app can work.
But now my customer wants to change his mobile so he wants me to change programming so that it works with any mobile.

how to do this for vb6 however i am using vb 2008 and the code for vb6 does not seem to work.
I have designed a form with a text box on it, and a command button underneath. The idea is to run this as a sort of stiky notes section.
I want the text box to read rich text into the textbox (C:\\stickynotes.rtf")
Then i have a command button underneath which i want to save the content of the rich text box to the rtf file (C:\\stickynotes.rtf). This is so that the user can edit and ammend information.
here is some code i have so far
Dim fileReader As System.IO.StreamReader
fileReader = My.Computer.FileSystem.OpenTextFileReader("C:\\stickynotes.rtf")

I am learning Visual Basic and I have learned alot of it from the learning section included in Visual Basic Express Edition 2008 but I don't think I have learned alot. I am actually trying to make an extractor and importer for a game. I have the file called Frontened.MNG and I want to make a program that can open the file. Someone else had made the rxtractor but he doesn't have it now. The Frontened.MNG file contains bunch of .DDS files and I want to view them in the program and then be able to replace the .DDS files in the >MNG file and be able to Extract the files out of the .MNG file. I don't just want anyone to do it for me but teach me how to do it step by step. First I want to know is how to view the .MNG file in VB? It should be viewed in a listbox but I don't know how to read this file in VB. I know how to read a text file but I think this is a binary file and it is viewed differently.

I have a text file, with several lines of comma delimited data. The easy part is that each item fits into the same field, so I can use a 2 dimensional array. I would like to use .net classes to do this, not the old file handling functions I was used to.How can I take the text file and load the data in the text file into a 2 dimensional array.Here is example data in test.txt
1,1,1,2,2,2,1,1,1,3,3,3,4,4
2,3,4,5,1,1,1,2,3,4,5,1,1,1
2,3,4,5,6,1,1,1,1,2,2,3,3,4
So this would go into a (14,3) array.I would like to make sure, that the array is automatically sized to the size of the data also.
