Opening a file from a web app VB.NET -

i trying open file on web app retrieving file path sql database

here code open file when double click index in listbox.

protected sub userdoubleclick()     dim selectedpath string      try         fileconnection.open()           selectedfile = filelistbox.selectedvalue          'takes selected items listbox , searches database file          'and open file user         filecommand.commandtext = "select filepath importedfiles filename = '" & selectedfile & "'"          filedatareader = filecommand.executereader         while filedatareader.read             selectedpath = filedatareader.getvalue(0)         loop          system.diagnostics.process.start(selectedpath)      catch ex exception      end try      fileconnection.close()   end sub 

when run on local pc works fine when publish server wont open file.

system.diagnostics.process.start(selectedpath) open file on machine running web application; in other words, opening on local machine when running locally, opening on server when deployed. isn't going work.
