I have an application that needs to read a file path from app.config file and the path has to contain username, based on the logged in user.

For example the path is C:\Documents and Settings\JOHNDOE\My Documents\

is there a way to do something like this:  

C:\Documents and Settings\%userprofile%\My Documents\

to make the path more dynamic?

I assume that you are logged in with that user in the application ?

Use this to get the myDocuments folder path for the logged in user:

myDocsFolder = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)

Thanks, that's a good link but not exactly what I am looking for.

First of all, I need to pass the file path through app.config file in a dynamic way.

Second, the file path not necessarily will be in C:\Documents and Settings

Basically what I need to know is how to pass a varibale similar to %userprofile% through app.config file in VS.NET

Inside <appSettings> Tou can create application Keys

<add key="KeyName" value="Keyvalue"/>
Later on you can access these values using:

ConfigurationManager.AppSettings["Keyname"]

I do not know if it can be that dynamic, but there is a work-around:
1. Make the file path like this in the app.config:
C:\Documents and Settings\%userprofile%\My Documents\
2. After you read the file path into a string, replace the sub string "%userprofile%" with ENVIRONMENT.USERNAME

Dim strPath as String = "C:\Documents and Settings\%userprofile%\My Documents\"
strPath = strPath.Replace("%userprofile%", Environment.UserName)

Still not totally clear what you are asking for. You don't seem to ask about the path so I would assume the path is not the issue. If you only want to be able to incorporate the current userprofile you could just make your app.config file contain the word 'myuserprofile' and then replace that string with the actual userprofile as in (using the path in your example):
<appSettings>
<add key="Mypath" value="C:\Documents and Settings\myuserprofile\My Documents" />
</appSettings>

To read the data back into your application, you would use something like
the following:
Dim MyPathName as String =
System.Configuration.ConfigurationSettings.AppSettings("Mypath").replace("myuserprofile", My.User.Name.ToString())
