Hi Alok,

When you need to connect to a database or a file from your webpage you'll need to know the exact file path to that particular datasource.
If you aren't sure of the exact physical path then you can use Server.Mappath. Server.Mappath takes a path as a parameter and returns the exact physical location of that file on the hard drive.
For the examples below, the database "mydatabase.mdb" is located in the c:\inetpub\wwwroot\database directory. The c:\inetpub\wwwroot directory is set as the web root directory.

Our script uses the slash character to specify that the path returned should treated as a complete virtual path on the server and mapped from the root folder.
<%= Server.MapPath("/database/mydatabase.mdb")%>
This script outputs the following:

c:\inetpub\wwwroot\database\mydatabase.mdb
Because the path parameters in the following example does not start with a slash character, it is mapped relative to it's current directory, in this case c:\inetpub\wwwroot\database.

<%= Server.MapPath("mydatabase.mdb")%>
This script outputs the following:

c:\inetpub\wwwroot\database\mydatabase.mdb
So in a nutshell the MapPath method maps the specified relative or virtual path to the corresponding physical directory on the server.

Hi Alok,

Each file on a Web server has two ways of being accessed - through a virtual path and through a physical path

We use Server.MapPath to obtain the physical path of a particular directory.

Hi Alok,

Server.MapPath():
The Server.MapPath method can be used to retrieve several interesting properties about the running ASP application, for example:
For example, you can store the application's root directory in an Application variable, and use it to dynamically build physical paths to other files and directories.

' the current directory
currDir = Server.MapPath(".")

' the parent directory
parentDir = Server.MapPath("..")

' the application's root directory
rootDir = Server.MapPath("/")
