It prints out the content of the txt file twice & I would like to read line by line and store the line in a string.In vb 6.0 I used a socket to create a server & client chat app.Is there some other possibilitys than to use a C4F P2P toolkit for Vb 2008?

I've gone through about 16 hours and two packs of cigarettes trying to figure this out. First a little background. I was using 6.0 up until 2004 when I went to prison. I'm out now, and trying to relearn the trade, using VS 2005. I'm currently porting some 6.0 code from another project, SpyCast Webcam Studio, into VB 8.0. It's disheartening, to say the least. None of the old built-in subs/functions work anymore, so I have to scour the forums to relearn each and every function.The section I'm doing now takes a snapshot from the webcam (Video API --> PictureBox --> Save as Jpeg), then upens the file to upload it to the server via HTTP POST. I've been using this code in SpyCast for years with no trouble, but I spent many hours trying to piece together the right code to open the binary file to read its contents. I pieced together two methods I found around the forums, one using FileStream() though the code I found wasn't for binary files, even though it said it was, so that code doesn't really work. Method two uses Microsoft.VisualBasic.FileOpen() and works better.
Here's the kicker. By the time I run through the rest of the rigamarole of uploading the file, by the time I read it on the webserver, it's *slightly* corrupted. It's a valid Jpeg, no errors, but the picture looks like when I use to watch the Playboy Channel when I was a kid scrambled with weird colors and whatnot. [code] Each "chunk" is basically one "line" of the file. It looks like a single LineInput() return is the text between two carriage returns. Am I correct? I tested this with a flat text file, and it looks true. However, That one input line returns the text or data with the carriage returns *stripped*! ***?!? =( Fine, I have no problem adding my own vbCrLf to each LineInput(), if I were opening text. but this's binary. A character could be Chr(10) or Chr(13), both of which are removed from the original file contents.So I could very well need to use something other than LineInput(), but I haven't found any other examples on the web using this method.

I'm using Visual Basic express 2008.The application I am working on is the first major project I have ever undertook with visual basics. The application is a launcher for a private server for world of warcraft.I have a menu bar that pulls the file path of the wow.exe and puts it in a hidden textbox, I then have another option that saves this text to c:wowexe.txt. All of this works GREAT!
How can I read the .txt file to end and return the information stored in the .txt file to this line of code.
Dim RetVal
RetVal = Shell("This is where I need the data from the .txt file to be seen", 1)
If your wondering why I don't just type in the path of the .exe, it's simple, not everyone installs World of Warcraft on the C drive.

I would like to write a code to read data from .gpx file, but I get stucked with classes: I have a problem with creating working array of objects in object and setting or getting data from it.

Module Module1
Sub Main()
Dim i As Integer

I need to read lines from file. Now my code is like this:
Sub data()
Dim reader As New IO.StreamReader("log.txt")
For i = 0 To 1500
date(i) = reader.ReadLine
Next i
End Sub
Now if some user will change add or remove the data from this file, it will end up with error or sth. I also tried to write sth like this:
Open "C:in.txt" For Input As intInFile
But there appears an error, that open is not declared and IO functionality is microsoft.visualbasic namespace. I added this name space (at the top: Imports Microsoft.VisualBasic), but this error still occurs.

My question is a rather simple one and to be honest with you, I am not sure if it can be done. Lets say I have a mutli-line text box, is it possible, and if so how would I go about making it so if I clicked Open with > editor I could do things with this text, such as TextBox.text = [file contents]. If it's not possible just let me know and I'll stick with open file dialogs.

Im trying to make a game launcher, and I want to have it first see if there are updates. I know this is a really simple problem, but I can't figure it out. This is the code. I want it to read the link.txt and version.txt in the same folder instead of C:/ Oh and make it so it unzips the update into the same folder, and replaces the old files for the new ones.

I created an application that I use when deploying packages which allows users to postpone it from running until they are ready. There are two text boxes that contain restart warning messages.
Is there a way I could use an external file such as an INI where I could place a different message? If the app could read the messages in the text file at runtime and place them in the appropriate text box, it could make this app a little more flexible.
As it is now, if managers want the message changed, I have to change it in the source and recompile. That is not a good way of accomplishing the change.

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'm currently making a program in Visual Basic 2010 for my Course work, and I'm struggling a little as it involves a "log-in system."
The system will save the Users Information in a folder (Called UserInfo.txt) (Address, Password, Email etc..), and the folder name being the username of the User.
When an Admin wants to view or edit a User, I want the Admin to be able to select the User from a drop-down list and when selected, the information of the user loads in and is displayed in the text boxes bellow (on the same form). The Information can then be edited and Saved back to the file of that user selected with a "Save" button.

I'm trying to get a random line of text to appear in a messagebox upon button click, I want the listbox to be closed while the action is to be performed.
I can do it when the listbox is open but not when closed, here is what happens if I try to do it when it's closed
and the message "InvalidArgument=Value of '0' is not valid for 'SelectedIndex'."
I tried reading it straight from the .xml file the data is stored on, but that didn't go so well either.

I am reading in a line in this format: AL93895200 How do I get each of the items in the line that are separated by a space. I think it should go something like this:
Dim line As String = fileReader.ReadLine() Dim fields() As String = line.Split(How do I get it to split at the spaces?)
But as you can see, I don't know how to actually get that to work.

I'm working on a new application for one of my Managing Editors at my company. We are wanting to build an application that only has 4 combo boxes for user options and then according to the options that the user selects, the application will spit out 3 random lines of text that can be copy and pasted into another application that we use.We are in the process of creating a rather large (1000's of lines) CSV file that we are going to use as a repository for the text. Let's call the data file SRG9000Data.csv..I'm almost 100% certain that I'm going to need to read in the entire datafile as an multidimensional array because we are setting up the CSV file as follows:[code]For each of THOSE categories, I'm looking at having 8 possible items for <Sports>, and 3 items for <PlayType>, <GameImpact>, and <Scoring>. <Text> is being use as a possible Text Phrase that the system can select from randomly provided that the other area's of the array are met.The CSV file will have 1000's of lines. Of those, the system will "filter" though all of them so that ONLY the ones that meet the selected criteria can be used, then choose 3 of them randomly and use that as output.
Extra information: I am currently establishing that the CSV file being used is setup as 0-7 for <Sports> (0 = Baseball, 1 = Basketball, etc..), 0-2 for <PlayType> (0 = Defensive, 1 = Offensive, 2 = Other), 0-2 for <GameImpact> (Negative, Neutral, Positive), and 0-2 for <Scoring> (0 = Non-Scoring, 1 = Other, 2 = Scoring); <Text> is a String.I am clueless when it comes to setting up an array like this; It's been many many MANY a year since I worked with array's in QB and I feel I may need more than a refresher course.Now, if I'm understanding correctly from some of the forum lurking i've been doing, multidimensional arrays CANNOT be of mixed type, correct? If this is the case, the how can I read the entire CSV file into an "array" (if you will) so that it contains Integers AND a String? [code]
