stuppie Posted June 3, 2010 Share Posted June 3, 2010 (edited) Is there a quick way to check if an inputted string is a legal file/path name ? As in, does not contain slashes, asterisks, question marks, etc, but still can contain dashes and underscores (so, isAlphaNumeric() won't work).

PsaltyDS Posted June 3, 2010 Share Posted June 3, 2010 Search the forums a bit, I'm sure someone has posted an applicable StringRegExp() pattern for that. Valuater's AutoIt 1-2-3, Class... Is now in Session!For those who want somebody to write the script for them: RentACoder"Any technology distinguishable from magic is insufficiently advanced." -- Geek's corollary to Clarke's law Link to comment Share on other sites More sharing options...
stuppie Posted June 3, 2010 Author Share Posted June 3, 2010 I did search, but I didn't find anything because I looked for "legal" path name instead of "valid". So here it is as a reference for anyone else who is looking for this: http://www.autoitscript.com/forum/index.php?showtopic=113403 Link to comment Share on other sites More sharing options...
Moderators SmOke_N Posted June 3, 2010 Moderators Share Posted June 3, 2010 I did search, but I didn't find anything because I looked for "legal" path name instead of "valid".So here it is as a reference for anyone else who is looking for this:http://www.autoitscript.com/forum/index.php?showtopic=113403Looks like that first function would consider a UNC path to be invalid. I'm also not sure if that is a cross platform from NTFS and FAT systems.Anyway, If I were going to personally write a func for it, I'd be sure to read the "File and Directory Names" part of this link: http://msdn.microsoft.com/en-us/library/aa365247%28VS.85%29.aspxAnd of course, as Psalty said, create a regex patttern for it based on the link info. Common sense plays a role in the basics of understanding AutoIt... If you're lacking in that, do us all a favor, and step away from the computer.

Hope this helps. $String = 'C:\Users\SomeUser\SomeFolder\Some_File.txt' ;Full path. $File = StringSplit($String,"\",1) $File = $File[UBound($File) - 1] ;File Name. Msgbox(0,"Result:" , StringRegExp($String, '[:"?*\/<>|]', "")) Msgbox(0,"Result:" , StringRegExp($File , '[:"?*\/<>|]', "")) Link to comment Share on other sites More sharing options...
jchd Posted June 3, 2010 Share Posted June 3, 2010 Slashes are perfectly valid in paths under Windows and are equivalent to backslashes for Windows programs with some exceptions.

GEOSoft Posted June 3, 2010 Share Posted June 3, 2010 This should be close but it must have a path and file name, not just a path. $sPath = @DocumentsDir & "\Some folder\somefile.txt" $bValidPath = False If StringRegExp($sPath, "^([a-zA-Z]\:|\\\\[^\/\\:*?"<>|]+\\[^\/\\:*?"<>|]+)(\\[^\/\\:*?"<>|]+)+(\.[^\/\\:*?"<>|]+)$") Then $bValidPath = True George Question about decompiling code?

If we follow the msdn link I provided several beers ago... I could fathom something like the following working: expandcollapse popupFunc _PathIsValid($s_path, $f_isdir = False, $f_usedin_IO = False) If StringLeft($s_path, 2) <> "\\" Then If FileExists($s_path) Then Return True EndIf ; for possible relative path $s_path = _PathFull($s_path) Local $s_drive, $s_dir, $s_fname, $s_ext _PathSplit($s_path, $s_drive, $s_dir, $s_fname, $s_ext) Local $f_unc = False If StringLeft($s_drive, 2) = "\\" Then $f_unc = True If IsKeyword($f_usedin_IO) Or $f_usedin_IO = -1 Then $f_usedin_IO = False ; validate this is not an I/O verification and not unc If Not $f_unc And $f_usedin_IO Then ; I/O API's convert "/" to "\" $s_path = StringReplace($s_path, "/", "\") If FileExists($s_path) Then Return True EndIf If IsKeyword($f_isdir) Or $f_isdir = -1 Then $f_isdir = False ; Concat dir and fname (and ext) if this is supposed to be a dir If Not $s_ext And $f_isdir Then $s_dir &= $s_fname & $s_ext $s_fname = "" $s_ext = "" EndIf ; If the drive doesn't exist, then it is not a valid path If Not $f_unc Then If Not FileExists($s_drive) Then Return False EndIf Local $s_fsystem = DriveGetFileSystem($s_drive) If @error Then Return False Local $iPATH_MAX = 255 Local $i_dirlen = StringLen($s_dir) ; 12 chars must remain for filename and ext (optional) If ($i_dirlen > ($iPATH_MAX - 12)) Then Return False Switch $s_fsystem Case "UDF" If $i_dirlen > ($iPATH_MAX - 1) Then Return False Case Else ; Only found NTFS, exFAT, UDF, and FAT32 with options for this If $i_dirlen > $iPATH_MAX Then Return False EndSwitch Return (StringRegExp($s_dir & $s_fname & $s_ext, '[<>:"/\|\?\*]') == 0) EndFunc Although I did not test UNC very much at all. Anyone is more than welcome to test it and or change the above code to be more appropriate.

GEOSoft Posted June 4, 2010 Share Posted June 4, 2010 I was actually looking for the one you and I worked out one night where we also checked the lenght of the path, I'm just not sure where I filed it at the moment. It definitly hasn't been added to a library yet. George Question about decompiling code?
