Read The .txt File To End And Return The Information Stored In The .txt File To This Line Of Code?
Dec 9, 2009
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 am making trying to make a program that can read the file information directly from a specified file, but I am having a lot of difficulty reading things like file comments.An example of this can be found in windows XP when you alternate / right click on any file and click on properties. You'll get a lot of extra information.Now I have a few questions about this.
1.Can this information even be read in VB.NET
2.If so how
3.If not do I need to create some kind of data file to store the file information
Here is what I did so far

what i need to do is open a txt file, read line by line, decode each line into an array and display. Now all works ok apart from one line.
sTextLine = objReader.ReadLine() <-- Value of string cannot be converted.

Dim objReader As New System.IO.StreamReader(sOpenFile.Text)
Dim sTextLine As New ArrayList()
Dim sText As String = ""

I have code that reads the whole file, not line by line.
Here is the code:
FileOpen(1, filename, OpenMode.Input)
Do While Not EOF(1)
datatodisplay = LineInput(1)
Loop
FileClose(1)
I would like to know how I can read the file line by line and then add all results into an array list.

Ok, I saw this code on the net
Dim sFileName As String
Dim srFileReader As System.IO.StreamReader
Dim sInputLine As String
sFileName = "D:UsersArbenDesktopSerieA.txt"
srFileReader = System.IO.File.OpenText(sFileName)
[Code]...
under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file

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 am trying to read a PDF file line by line using PDFBox.This is the first time I have ever attempted to do this with a PDF so I am not sure what I was expecting but I thought I would end up with some "mark up", which I could use to parse the lines I was looking for out of the file.
Anyway it didn't work out the way I had planned and I am not sure if that is because I am using the wrong tool or not using the right tool correctly.I managed to extract the text but I didn't really see any mark up that would be usefull to parse the file. Does anybody have any experiece with extracting test from PDFs. What tool(s) do you recomend?

I am quite new in VB NET, after VB. and unfortuantely I had to copy paste and merge the code fragments from some tutorials.
I have a folder including 200 eng files which can be opened by notepad. And each file has around 4000 row; with 60 field seperated by coma. I need to read specific row-field value at each files.
Now what I can is:
a) reading individual txt files and find specific value
b) listing all of the files in the folder
c) I can merge (a) and (b) and read all the files automatically, but since ram is continuously increasing, and at one point (sometimes 163, sometimes 169, or 170. files or something) it gives an error as "System.OutOfMemoryException". My ram is 4 GB and when I get this error the ram is increasing to more than 3 GB.
1- Could it be happen because of being eng files instead of regular txt files?[code]...

I need to be able to read the last line of a text log file - a bit like the Unix 'tail -f'. I'm using FileSystemWatcher which works well. There's more to it than that and more complexity to the app, and I have everything working fine except this bit. I've tried googling for it but I can't get any of the examples work properly.

I have to text file in the following format :
Word[tab][tab]Word[Carriage Return]
Word[tab][tab]Word[Carriage Return]
Word[tab][tab]Word[Carriage Return]
I want to get all the words before the tab into one array or to create a new text file and the all the words after the tab into another array or create a new text file too.
Here my function to get the words before tab into an array :
Protected Sub MakeWordListBeforeTab()
Dim filename As String = "D:lao�0001.txt"
'read from file'
[Code].....
I wrote the above function to get all words before tab but I got all the words into array. I've been trying to use the Split method above. What is another method to split those words ?
I know this can be done with regular expression but I don't know regex yet. If you can show me how to get this done with regex it'll be awesome.
