component based programming -global class availability

this may be more a .NET question, but it has to do with accessing tamino.
I have written a class for easy Database-access, which I want to use on several different pages of my application.
So I’ve read something about “component based programming”, which enables me to build my own DLL and use the classes globally by using namespaces and the using directive.
So the problem is, that I want to have my own class called DBhandler, which actually uses these:

using SoftwareAG.Tamino.Api;
using SoftwareAG.Tamino.Api.DataAdapter;

But, creating my own DLL does not let me use these two within it - since they cannot be found in the Classlibrary of my project - they are placed in the Bin Directory.
So my question is, is there a way to use them within my own DLL?

Or should I layout my application on one single page, so that I just need one code-behind file which always is accesible? I would prefer to split it into several pages, though.

Here again is what I have: an application with several pages, and what I need is to access my DBHandler class from every single one of them - and this DBHandler class actually makes use of the tamino API.

Any suggestions?


Ok, got it running now. I forgot to include a reference to the Tamino API…
