Stream Reader / Writer - Illegal Characters In Path
Apr 28, 2011
I'm trying to setup a simple app that reads a file and then writes the contents to another file using OpenFileDialog and SaveFileDialog. Looking at the debbugger it looks like it's reading fine, I can see the data I want written. Towards the end of my code I get the following error message:"Illegal characters in path". I've researched this error. I'm not using any illegal characters such as /\? etc and the pathname contains all alpha characters. I'm pulling the test file from the C drive and trying to save it there as well.
Path: C:\Test.csv
My code:
Private Sub btnAppendData_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAppendData.Click
Dim Result As DialogResult
Dim FileContents As String
[Code] .....

The bigger problem is that I can't seem to get everything involving using stream writer and reader working. If I start of with a .txt file already correctly formatted then I can display it in the list box. But adding data during run time is not proving successful.

I am trying to make my application read data from a file. Then save the data back. However I keep getting an error which says the file is still open so cannot be edited. I also read that there is an issue with the streamreader and streamwriter do not close the program straight away. I was wondering if anyone had a way around this or any alternative ideas. Heres my code so far!

I am new to Visual Basics and I am using Visual Basic 2008 express. I have been using video tutorial on line to learn VB and they are great in explaining what is happening the code vs. just looking at code. I think from what little I can find I would be using StreamWriter WriteLine and StreamReader readLine .I am using a couple of forms. I am looking for simple basic code to use a form as a way of modifying timer intervals and store the values in a single text file on separate lines.
Description:
Form1: will contain the main code that will run. It will contain some timers. I want the timers to look in a text file for their intervals. Each timer would be on a different line.
Example:
Timer1 interval would be located on line 3
Timer2 interval would be located on line 6
Timer3 interval would be located on line 20
Form2: will contain 3 textboxes. This is where when I load form2 I will also read the same values from the text file to preload the text boxes. I will now be able to change the timer intervals as needed and press a button to update the text file. The update button will also reload the new timer settings on Form1. This is very similar to how a CNC Machine works with Parameter settings. This can be useful for storing many different settings for a form that a user can modify and be stored and reloaded next time the program runs.

i have a list box or directory paths, the program basically copies the directory to a selected destination and moves down the list to the next path and copies that path. I'm having a few problems with this, but mainly this one where the application errors out and stops completely with this error:
"Illegal characters in Path."I would really like to address this and get it resolved, or is there anyway it can report this, but move on to the next path in the ListBox?

I am using the following code to get search results from The Movie Database.org using their api.
Dim xmltempdir As String = My.Computer.FileSystem.SpecialDirectories.MyDocuments.ToString & "cwbrowser emp"
Dim stylesheetlocation As String = xmltempdir & "searchresults.xslt"
Dim request As HttpWebRequest
Dim response As HttpWebResponse = Nothing
Dim reader As StreamReader
Dim result As String = vbNullString
[Code] .....
The line which is coloured red is the problem line. 'htmpath is shown as "C:UsersColinDocumentscwbrowser empsres.htm" which is correct.
Why I get the Illegal Characters In Path error.

What characters are illegal to use in a file path name? I tried to save a text file using a filename that had only a dash in it. I got an error that said Illegal characters in the path name. This happened when I saved it using the UTF8 and Unicode encoding methods. Also, which is better to use -- UTF8 or Unicode? Which encoding is used in Microsoft Word files?

I'm creating what should be a simple copy and paste type of program. Basically you put text in the textboxes and click the copy button to copy it to the clipboard. I have a text file attached to format the text when it is copied. With that in mind, when I run the program(debug), i can successfully use it once. But, after clicking the "reset" button to clear all of the text boxes for another use, I fill in the information as normal, I click the copy button and i get this popup titled "ArgumentException was unhandled" followed by the error "Illegal characters in path".
Here is the code >
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim ReadText1 As New System.IO.StreamReader(vartextfile1)
vartextfile1 = ReadText1.ReadToEnd

I have a program where I copy strings from one file to another. I then create folders based on the strings. It works great 99% of the time. Once in a while I get this error:
Illegal Characters in Path
Here's the line of code where it happens:
If Dir$(txtSaveLocation.Text & "" & name1 & "" & name2, vbDirectory) = "" Then
It is just checking to see if the folder exists yet or not.
When I move my mouse over the variable "name2" the value shows up as
"test name 2
That's right, no closing quotation marks. How is this possible? If I manually add the quotation marks while in debug mode and restart execution the code works fine.
I do have a function to strip out illegal characters first too:
For loopCTR = 0 To strip.Length - 1 'strip characters out
name2= name2.Replace(strip.Substring(loopCTR, 1), "_")
Next

I'm having trouble using the webclient to download a file. This same code works in another app that I'm using, but when downloading the second file, I get an exception saying that there are illegal characters in the path.The second item that it is having troubledownloading's filename is "Filename.exe.manifest". The RemoteUri is the download link, item is the name of the file. When I print out the path that it is downloading from and the path that it is downloading to, both are correct. I can type the address in the browser and it downloads fine. (The problem file is not exename)
For Each item As String In files
If item = exename Then
If My.Computer.FileSystem.FileExists(Forms.Application.StartupPath & "" & item & ".new")

i am creating a program which scans and saves images. in my program i have the option to save images and with each image i save it gets its own number for example: file1, file2, file3, file4 and so on. the only problem i have is getting the prgram to remember where it left off so it carry's on the number. my understanding is that i need to create some sort of stream writer or file stream class for this proccess to work. so it save's the last image number i was on, and carrys it on next time i open the program up again. and i also need it to re-write the new image number its on for next time. so i need to write and read the text file (.txt) and write it again if you catch my drift? i have a book to help but the wording in it is so confusing at the min, i m lost where to start.
