Ok, So I am making a front-end for a program, and it runs the exe with command line arguments. One of those arguments is creating a log file that tells me who the winner is. Currently I have code that runs the app, tell VB when it exits and then does another event. When testing with message box as the other event, works fine.
When running the System.IO.Streamreader the app just closes down on its own and there are no errors shown.

I have a device (a few actually) that connects via USB to a PC. From here it acts like a basic storage device using FAT32 as the file system. The other thing is that it won't accept drive names (C:, E:, G: etc) to it so instead you need to use its Volume GUID to connect. I have retrieved this painlessley through MountVol.exe but thats where the difficulties ended.I am not trying to access the file system through VB.NET/C#.net (either will be fine - fluent in both ;) ). In Windows Explorer I can easily visit '\?Volume{71E4C2C7-E511-4B2A-BF5C-569B2B25784E}apic' to access the device and its files. I can also use CMD and the Dir command to go through the files. Just .NET cant seem to cope. I understand the GUID changes on each PC and I am OK with this as I can use MountVol to get the GUID and run the console app with command arguments as it will always be a human initiating the command.
I have tried manually entering the path via Console.ReadKeys but this also fails to even see the directory above and any of the files inside one being 'dev' without an extention. I can use System.IO operations without extensions on "normal" drives (ie those
with letters) so I know it's not the extension causing problems. I did a Try/Catch with a StreamReader pointing to the file to see what was spurted out:
System.ArgumentException: Illegal characters in path.
at System.Security.Permissions.FileIOPermission.HasIllegalCharacters(String[]
str)

I made my own advanced networking system which uses System.IO.Streamwriter and Streamreader but offline. I would like to let this use a directory online, I have a webhost available for that, now how do I say to the program it has to look at a specific map with all the users information?

Just curious if I can let my network grow out international instead of pc. Also I have a second question. I made a create account page which is supposted to make a text file with the txtUserName and txtPassword inputs, but it does create the file, but doesnt write any lines into it.
Code here:
Private Sub btnCreate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCreate.Click
Dim UserGenerator As System.IO.StreamWriter

How can you make streamreader to split a line into two and place it on two different places of the form and how can you use streamwriter to delete/alter file contents.
View 4 RepliesI have a problem with a streamreader in visual basic 2008.I am updating a database from text files on an ftp server. The streamreader works fine until the file is more than 100,000 bytes long.It reads until it reaches this point and then just ends. No error message, it just reads to this point which happens to be 2 fields out of 6 in the database stream. My question is - does the streamreader have a limit? And if so what is a workaround?
Dim connString As String = "Data Source=" & pDataBase
conn = New SqlCeConnection(connString)
Dim strQuery As String = ""[code]......
I'm writing a program that basically loads an entire text file into a streamreader variable, then reads this variable line by line and parses and writes a line into a new text file. I'm VERY new and my knowledge is mostly self-taught, but I can't seem to get out of this one. It works for smaller files, but it appears to reach a limit in characters at some point because in a file of 900 lines, it stops writing about halfway through 800 and there are no errors, the program actually completes and the message box pops up.
There are a few things with this code I already know I should fix, such as creating the new text file name, it's messy, I just don't know how.
