Replication failed with Connector/C++

[lui lui]

Hi, everybody

I am trying to build Web Server with Apache 2.0, I have written some cgi in C++ with Connector/C++ 1.0.0 preview, and set MySQL Replication for backup, but i can't success completely. The Replication and cgi is fine, but my cgi has not produce any MySQL binary log, so Replication gets nothing.

above is my test code:
int main(void) {
connectDB();

Statement* stmt = con->createStatement();
stmt->execute("INSERT INTO nuuo.lui (lui) VALUES(1234)");
PreparedStatement *stmt3 = con->prepareStatement("INSERT INTO nuuo.lui (lui) VALUES(?)");
stmt3->setInt(0, 123);
stmt3->execute();

delete stmt;
delete stmt3;
retorn 0;
}

Anyone can help me how to fix it?

thx a lots
