vb.net

In order to make a CRM in drupal that has a local and a remote version I had to try to synchronise the two.
I have tried to do that in three steps

Good to know is, that I made the synchronisation program in vb.net, my knowledge of PHP was to small to make it in PHP.
It will only work with mysql 5 because that has the table with meta-data (information_schema)
I don't know if mysql 4 has this but I have been told that it hasn't.

The program is dual layered. It has a data connection layer that handles the connection between the program and mysql.
