Develope a program to modify MSysObjects

We need a small example Code which allows us to modify the content of the Table MSysObjects in any Access Database. We need this for an other project. The example should be written in VB.NET or C#. It has to be a running example so we can test it with some Access Databases. Warning: The MSysObjects Table is a hidden system-table in Access. It is NOT a normal Table you can directly access Thats the challange to solve here!
