Hi,

i have a db connection like this

dbpath="d:\database\data\CRM.mdb"
username="admin"
password="password"

then connecstring of

            Me.pvtConnStr = "Provider=Microsoft.Jet.OLEDB.4.0;" _
                      & "User ID=" & Me.username& ";" _
                      & "Data Source=" & Me.dbpath& ";" _
                      & "Jet OLEDB:Database Password=" & Me.password& ";"

Before, when i run asp (developed using dreamweaver), i could just change the dbpath to sumthing else.
Now, i have converted it to VB.net asp project.
now i cant change the DBpath anymore, i have to recompile and deploy it back to the server.

How do you guys do it?
best practices?

You have configuration files in .net applications. Config files provide coniguration information at runtime and the great thing about the config files is that you can change the configuration information without recompiling the program. So here are the steps:

1. In your VB.Net application, open the web.config file. If you are not using VS.Net, then just add a file called web.config under the root directory of your website.  It should lok something like this:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.web>
   .
   .
   .
  </system.web>
</configuration>

2. Now, add your DBPath as a configurable parameter under a tag called appSettings.

<configuration>
  <system.web>
   .
   .
   .
  </system.web>
  <appSettings>
    <add key="DBPath" value="d:\database\data\CRM.mdb" />
  </appSettings>
</configuration>

3. In your code you can read this value as
    dbpath = System.Configuration.ConfigurationSettings.AppSettings.Item("DBPath")

Now, you can change the value of DBPath in the web.config file without recompiling the application. Refer to the following url for a detailed demo of the configuration files.
