Hi Guys and Girls,
I have a situation where I am wishing to deploy a .NET dll onto a number of
servers. The classes in the DLL will be used by VBScripts. When one of the
classes - Connection - is instantiated from a VBScript the code looks to a
simple text file for initialisation of certain variables. I want this text
file to reside with the dll when it is installed (via a setup project) and
have the file opened by the Connection class in the installation directory.
At the moment I have:
StreamReader sr = new StreamReader(@"config.ini");
and I use this stream to read in values. However, the path I have specified
here will be looking, when the object is made in the VBscript, where the
VBScript is located. How can I get it to look at the installation directory?
Any suggestions would be good,
Thanks,
Jesse
If I understand you scenario correctly you could simply use
..NET's built-in ConfigurationSettings functionality. If your
assembly is called "MyConnection.dll" create a configuration
file "MyConnection.dll.config" that resides in the same
directory as the assembly. Add your connection string to it:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="MyDatabase.Connection"
value="server=(local);database=mydatabase;Trusted_ Connection=true"
/>
</appSettings>
</configuration>
So here the "key" (whatever you name it) merely gives you a
handle to the "value" which happens to contain your
connection string.
In your class simply use:
using System.Configuration;
...
string connectionString =
ConfigurationSettings.AppSettings.Get("MyDatabase. Connection");
or even
private SqlConnection connection =
new SqlConnection(
ConfigurationSettings.AppSettings.Get("MyDatabase. Connection")
);
connection.Open();
or whatever the equivalent VB.NET is.

If you have a username and password that could use some
obscuring, then investigate the aspnet_setreg.exe utility
that was originally developed for ASP.NET.

If you still need to know the where that assembly is then
this MAY be of some help:
