remove illegal characters for path

i am using unrar.ocx and getting the filename extracted from it which i am using to move the file extracted to another folder but i am getting the error
"illegal characters found in path"!!!! i debugged it.. what i found was weird is the filename variable have value:

"c:\temp\myfile.txt

with not quote at the end.... my question is ..is there a way to remove all illegal characters in a path to make it correct???

Perhaps there isa better way but the following will work:

VB Code:

Private Function CheckAndClean(ByVal StringToCheck As String) As String
        '=======================================================================
        'purpose: Eliminate characters that are not allowed in file/folder name
        '=======================================================================
        Dim sIllegal As String = "\,/,:,*,?," & Chr(34) & ",<,>,|"
        Dim arIllegal() As String = Split(sIllegal, ",")
        Dim sReturn As String
 
        sReturn = StringToCheck
 
        For i = 0 To arIllegal.Length - 1
            sReturn = Replace(sReturn, arIllegal(i), "")
        Next
 
        Return sReturn
 
    End Function

oh it's not working :(:(:( still getting "illegal characters in path"... although when i msgbox the path... i find it ok...no special characters whatsoever

Are you copying/moving a file? If so, there is two paths, one source and one destination, have you checked both?

How do you get original string (the path)? Can you post few samples other than what you already did? There could be a null char (Chr(0)) which you need to replace as well.

checked both..see the pics... i find it very weird!!!

edit: preparing some samples....

here is a sample
- choose the .rar file
- select a file extracted from the listbox
- press "copy selected to" to copy selected file to directory of textbox...

i hope you find out wat's wrong...

jesus christ dude just add a " to the end of the filename...

hmmm... does it work??!? i already tried it... this doesn't work!!!

ok i think i found the solution.. here it is

i noticed e.g. if i have a file named "myfile.txt" ... and when i copy it to a directory, i get the illegal characters error.... and i see that the source file path is "c:\myfile.txt without the quote at the end... so that made me think that the illegal stuff is after the ".txt" ..somekind of weird illegal invisible characters... so i made this function...

VB Code:

Private Function cleanuppath(ByVal mypath, ByVal fileextension)
        cleanuppath = mypath.ToString.ToLower.Substring(0, InStr(mypath, fileextension) + Len(fileextension) - 1)
    End Function

this just remove everything found after "c:\myfile.txt"... so the illegal invisible characters are removed... i don't really know why it is like that ..probably that the .ocx was meant primarily for vb6 and not vb.net
