[RESOLVED] Update database with deployment information

What I want to do is to update an online database (web based) with information from an installation. I don't want to include the database application part in the application itself for with VB that could make the app 10 times larger than it is now. What I want to do is find a way to update the database (real time or by file upload, but prefer real time). What I definitely do not want is to use the web browser in the manner that php or cgi does by putting the information in a web browser that can be seen. This information is password and keys that need to be logged to the database for the app to function, so it CANNOT be seen by users etc...

What is the methodology that should be used for such a deployment?
