Connector C++ with Visual Studio gives a memory access error (no replies)

Hi, I am trying to connect to my mysql database with a widow client using Visual Studio. Even if I follow every step of the tutorial: http://blog.ulf-wendel.de/?p=215
I get a memory access error. The error occurs the moment connect(....) is called.
I am thankful for any hint!!
