Determine if a File existsI tried using the system.io.file.exists function, that will appears to locate the file if I use the complete filespec, when I move the project to the web server, that command will not work because I can not specify the entire path, just the path relative to the default project folder. Example This is the path my image property uses: "~/image/NoImageAvailable.jpg" If I use the above system.io.file.exists fails if I use the full filespec: " E:\Documents and Settings\Steve\My Documents\Visual Studio 2005\WebSites\GshockWatch\NoImageAvailable.jpg" If I use the above system.io.file.exists succeeds. You see how the second example would not work on an ISPs server. any suggestions. thanks steve Server.MapPath

what the entire path of the file from the root is, which is what this command appears to return, I need a way to specify the path from the home folder on the web site, on most servers I dont have access to the full root and they differ, Im trying to use a path that will work on any server. thanks Show quoteHide quote "Jeff Dillon" <jeffdil***@hotmail.com> wrote in message news:ul63q3nXGHA.196@TK2MSFTNGP04.phx.gbl... > Server.MapPath > > "Stephen E.

Either server.mappath will give you the fully
qualified path, or simply a relative path from the root will always work too File.IO needs the fully qualified path. Jeff Show quoteHide quote "Stephen E.

ok, that makes sense, I assume in Windows land I can use the ".." for current folder, do you know if there is a specification for home folder in windows land? thanks Steve "Homer J Simpson" <nob***@nowhere.com> wrote in message news:c%j%f.72479$%H.41820@clgrps13...Show quoteHide quote > > "Stephen E.

Gates copied from) "Special' folders, like My Documents, do have specific .Net names. I've seen that question answered here before. However there is no real 'Home' folder in Dos/Windows etc. See "My.Computer.FileSystem.SpecialDirectories Object Members" and "My.Computer.FileSystem.SpecialDirectories Property" for the paths etc. /include/somepath/filename
will always be from the root of the virtual directory like c:\inetpub\wwwroot\vdir\include\sompath Jeff "Homer J Simpson" <nob***@nowhere.com> wrote in message news:c%j%f.72479$%H.41820@clgrps13...Show quoteHide quote > > "Stephen E.
