How do I secure a carrer in Software/Database design

I recently completed courses at a technical school for C++, Visual Basic, Oracle, SQL and other courses in an attempt to enter the IT industry. Unfortunately this does not seem to be the correct course. I have been searching for jobs in the IT industry now for two years. I was able to find employment with a small company beginning September of 2002 but the amount of money was not great enough for me to keep up with the bills I encurred while going to school. I am still hoping to find a way into the industry but have not even received a response from any companies I have applied to. If anyone has any suggestions they would be greatly appreciated. Thank you for your help.
