Question

How can I Use Server.MapPath() when the filename has a comma in it?

Asked by: maytawn

I'm trying to use the Server.MapPath() method to check for the existance of a certain file.  Unfortunately the file that I'm searching for may have a comma in the filename ex <c:\test, test.txt>.  I have no control over the filename so I need to find a work around that will allow me to use extract the actual full path of the file.

Currently I get the following error:

Server.MapPath() error 'ASP 0173 : 80004005'
Invalid Path Character

Server.MapPath(Server.htmlencode("c:\test, test.txt"))

~Ixeus

(think this will work?)

 

by: AlfaNoMorePosted on 2001-08-30 at 01:44:22ID: 6439697

Why are you using Server.Mappath when you have the full path anyway? If you pass "C:\test, test.txt" to server.mappath, it probably will cause an error. What you put inside mappath is the virtual file path: Server.Mappath("/directory1/directory1.1/test, test.txt")

And this will be converted into something like: "C:\InetPub\WWWroot\Server1\directory1\directory1.1\test, test.txt".

I don't think that throws an error Alpha, it just gives what you give it... I believe he just gave an example, not what he actually did... but if he did. I don't know

These are the errors I got with:

Server.MapPath("C:\test, test.txt")
"The Path parameter for the MapPath method must be a virtual path. A physical path was used."

Server.MapPath("test, test.txt")
"An invalid character was specified in the Path parameter for the MapPath method."

Server.MapPath(Server.URLEncode("test, test.txt"))
D:\SERVER-CLIENTS\Bis-Web\2-Sites-Not-Hosted-By-Bis-Web\A&L_Intranet\_management\test%2C+test%2Etxt

So I guess it works with your example then lxeus?

 

by: daveamourPosted on 2001-08-30 at 02:28:44ID: 6439839

Can we use Server.MapPath("test" & chr(44) & " test.txt")

?

Dave

 

by: IxeusPosted on 2001-08-30 at 02:32:54ID: 6439856

I believe Server.Mappath(Server.HTMLEncode("test, text.txt")) would work fine...

did it?

 

by: daveamourPosted on 2001-08-30 at 02:36:29ID: 6439863

Server.HTMLEncode is used to preserver characters displatyed in an HTML page from not being interpreted as HTML  - ie displaying a less than sign

All the work here is done on the server so I don see how this solves anything

Dave

 

by: IxeusPosted on 2001-08-30 at 02:37:17ID: 6439865

Believe so Alpha, I use Server.HTMLencode for any field manipulation or parameter passing, simply cos of illegal chars throwing errors...

p.s. I think he went to bed...

 

by: AlfaNoMorePosted on 2001-08-30 at 04:06:29ID: 6440082

I think Server.URLencode is the one to use. Surely Server.HTMLEncode would do nothing to "test, test.txt", as there's no illegal characters in there?

Server.URLPathEncode might be the real one to try?

 

by: AlfaNoMorePosted on 2001-08-30 at 04:07:55ID: 6440089

And maytawn... WAKE UP!!!!

 

by: IxeusPosted on 2001-08-30 at 04:12:41ID: 6440106

blehhhhhhhhhhhhh what everrrrrr :p
same difference, idea was there
oh well =p

guess yours then

 

by: GreenGhostPosted on 2001-08-30 at 04:20:32ID: 6440129

If you have a file at "/work/test, test.txt" you can user Server.MapPath("/") to get the path to the applications root, then add the virtual path. If you have a file at "work/test, test.txt", you can user Server.MapPath(".") to get the path of the current folder, then add the virtual path.

Function GetPath(strFile)
   If Left(strFile,1)="/" Then
      GetPath=MapPath("/") & strFile
   Else
      GetPath=MapPath(".") & "\" & strFile
   End If
End Function

 

by: GreenGhostPosted on 2001-08-30 at 04:23:10ID: 6440137

...and maybe replace / with \ in the name, if the file system is picky...

Function GetPath(ByVal strFile)
  strFile=Replace(strFile,"/","\")
  If Left(strFile,1)="/" Then
     GetPath=MapPath("/") & strFile
  Else
     GetPath=MapPath(".") & "\" & strFile
  End If
End Function

 

by: maytawnPosted on 2001-08-30 at 19:37:55ID: 6443349

AlfaNoMore & Ixeus thanks for the suggestions, but neither Server.HTMLEncode nor Server.URLPathEncode work in this case.  I am checking for the existance of a file and if the file name gets converted to have percent signs in it then it will not propperly find the file even if it exits.

Points split between me and lxeus?

We don't know what the reasons are for this not working on maytawn's machine, as they never reported the error!

 

by: IxeusPosted on 2002-01-08 at 01:44:17ID: 6717267

Wow, long time ago, I totally forgot about this question lol

Yeah that would be nice, hopefully he gets this mail and does something.

That's great :)

 Hate it when people do this.  They abuse a good system... augh.

Anyway, thanks ahead of time.

Please award 50 pts to AlfaNoMore and 50 pts to Ixeus.  Neither of their answers actually solved my problem... I had to solve it a different way.  But they were helpful so I would like to award the points to them.

Thanks
