Build C++ program in VC++ Express Edition 2005

I have an existing C++ program. I need the following done: 1. Update a function in the cpp file. Right now, this function hardcodes a parameter but I will like to have this parameter passed as a variable. 2. Compile and Build this program in a Visual C++ Express Edition 2005 environment. If you need to build in an SDK, that will be fine. I don't have a license for VC++ so I have chosen to use the express edition or sdk which are free. The condition for payment is the code is able to build on my server. I already have software on server or if additional software is needed, you can install it after permision from me. My server where the code must be able to build and run is Windows Server 2003 Standard Ed. thanks
