Working on a small program that saves a file path to a text file and then when run opens the text file reads the file path which will be the only line in the file. I believe I have traced my problem due to the character that would be in the text file when hitting enter to start a new line which I assume is "vbCrLf".
[Code]...
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?
View 2 Repliessave/create a file with a character such as ; or or * in the name then windows will tell you that you cant do that. However, this is obviously possible via some programming languages (im assuming VB.NET probably throws an exception if you try this).So here is my situation - my program works with some files that are produced by a third party program and these files get named whatever the subject of the email that each file relates to was. So if one of these emails had a subject of "Hello ;" then the file would be saved as that name by this third party program. The problem is when my program comes to rename this file or move it then it just throws an exception basically saying that the file doesnt exist, however it works perfectly fine with files that dont have these illegal characters in so it is definitely that thats the problem.
View 17 RepliesSo I have a program that parses a text file, and replaces keywords in it based on some criteria I've set up.I open the file, read it into a string, replace a line, then write that string back to a file.My problem is if the text file has any international characters in it, they get eaten when I rewrite the file.

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'm looking for a solution that will search a given directory and if it finds any illegal Windows file names it alerts the user:
/ : * ? " < > |
But I have no idea where to even start.
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

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.
I can copy about 15 files, and then it says "Illegal characters in path".However, I can't see any ilelgal characters.To top path is the destination, the bottom path is the source.

I am retrieving string values from a table and then encode each term to make a httpwebrequest to an api. It works fine and the terms allow for foreign characters like japanese/arabic/chinese etc and these are inserted fine. The problem occurs when some of these terms contain weird characters and that is when the request is bad. The only reason it is bad xml and the template I follow gets invalid are when these characters are present. I use the
system.securityelement.escape
And also
httputility.htmlencode
As part of my cleanup. One of the weird characters ends up appearing as a space but it is not since the trim(term) does not work and when I look at the xml in visual studio it looks like an ' &' with arrow pointing up attached to it. It does not appear after I pasted it here.It appears as a line feed or carriage return and I have tried to remove that too. Anyway is there some way I can ensure that these sort of characters are removed and if I were to use the binary values like <32 invalid, will foreign characters then get excluded.
temp = temp.replace(vbCr, "")
temp = temp.replace(vbLf, "")
temp = SecurityElement.Escape(temp)

I need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.
Here's what I know:
1. how to open a new file
2. how to specify the record length
3. how to close the file
Some specific questions:
Does the record length have to be constant throughout the file?
Can I read the nth record without reading the whole file?
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 need to find illegal characters in a windows forms textbox
The textbox text is sent as an sms text message and illegal characters are not allowed
e.g 1 client pasted some text from a word document into the texbox and the ' in msword appears as slanting ' in the textbox (see below)
e.g msword text - This is a new test of the Services
after pasting in textbox - This is a new test of the Services
The sms company have advised the slanting apostrophe is a unicode character
How can I find characters like above so I can remove them before sending the sms text

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)

I am working on a VB Console Application that takes an Autocad drawing type DWG and converts it to a PDF using a shell command that calls a third party application. In this case, acmecadconverter.exe from www.dwgtool.com. Then the PDF that is created needs a unique watermark, so I call a second application for that called pdftk.exe from www.accesspdf.com/pdftk/.
Everything works as intended, except when I try file names that contain spaces. The file system object does not tolerate spaces in the drawing file name. For instance, the following command gives me a system.io.filenotfoundexception...
My.Computer.FileSystem.RenameFile("Test Flowchart1.dwg", "Test~Flowchart1.dwg")
