    Generic path description - please help

    Hi,

    I have a VB.NET class library and I have to access a xml file that
    will always be in the same directory as the class library.

    So I use the followign code to open the file:

    Dim doc as XmlDocument
    doc.Load("C:\fo lderA\folderB\a .xml")

    Thing is though this path is subject to change. Is there any generic
    way to say that a.xml will always be in the same folder as this? Do
    you know what I mean?

    Any comments/suggestions/code-samples much appreciated.

    Al.

          Hi,

          Ken's solution is very robust and foolproof, but if High security is
          not your priority, you can also use relative paths, like :

          Since the xml file is in the same directory as the class library,
          ------------------------------------------
          doc.Load("a.xml ")
          ------------------------------------------

          However this has many disadvantages from the Canonicalizatio n point of
          view. So to make it more robust, we can use :
          ------------------------------------------
          Dim myXmlPath as string = "a.xml"
          Try
          Dim exactPath as string = System.IO.Path. GetFullPath(myX mlPath)
          doc.Load(exactP ath)
          :
          :
          Catch ex as Exception
          :
          End Try
          ------------------------------------------
          HTH,

          Regards,

              In addition to that, you may want to use 'GetExecutingAs sembly' instead of
              'GetEntryAssemb ly' in order to get the path to the DLL containing the call
              to the method.

                  Thanks everyone - problem is though I keep on getting the wrong
                  directory. Depending on what technique is use I either get:

                  C:\windows

                  or

                  C:\windoiws\mic rosoft.net\fram ework\v1.4322\e tc...


                  Confused,
