    Memory Usage Just Keeps on Increasing

    I have a problem with a program I'm writing. I'm doing it in Microsoft Visual Studio .NET with c++ and using mysql to access a database. The problem is the steadily increasing memory usage, which over time just keeps on going up. I assume the problem is because I'm not freeing up memory...
