[URGENT HELP - S.O.S.] WINXP + VS 2008 + C++ = Uncontrolled Exception

Hello, i need urgent help because i'm obtaining a error that i don't understand.

I have to develop a win 32 application that connects to a mysql bd. After try to develop with some IDE i have decided to develop with Visual Studio 2008 because i want to use qt interfaces and VS 2008 have an add-in with this purpose.

I have followed the instalation process of the this web:

http://dev.mysql.com/doc/refman/6.0/...al-studio.html

And i have tryed the complete example of this page:

http://dev.mysql.com/doc/refman/6.0/...example-1.html

Here start the problems. Firts of all i have tryed to run this example with visual c++ 2008 express edition and everything runs ok. Then i have tryed to develop an example with qt libraries in visual c++ and i get some problems with it. So i find that there is and add-in to use qt with the complete visual studio. And i tryed and it works perfect. The problem is when i try to use the example of mysql with microsoft visual studio 2008. When i develop the example i get this error:

"Exception not controlled in 0x0042e081 in prueba2.exe: 0xC0000005: Acces infraction when reading the ubication 0x0000000f."

I don't understant why works on visual c++ 2008 and not in visual studio 2008... I do everything equals in both versions... Trying to resolve this i add a catch at the code (you can see the code at the end of the post), but there weren't satisfactory results.

Thank you very much, i hope to somebody helps me!!!

Imanol.

Code:

Where are the calls to "new"?

Also, please use code tags when posting code.

Hello, thanks to answer me.. I'm sorry for not using code tags I didn't think about it...

I tryed what you said, but i get the same problem. In the page of mysql said that you have to delete the instances after.. i don't know why 'cause there aren't any "new"...

I can't understand why works the same example in Visual C++ 2008 and not in Visual Studio 2008...
