Arduino with C/C++

I have design a code in Software Arduino Uno to move to servos, now I'd like to execute this code in Visual Studio 2010 in Windows Vista. I don't know how to choose the digital outputs and to send the position like integger, thus, I'm sending information to Arduino like string.

load the Arduino libraries in the c/c++ environment.

You don't know how to chose an output, but you know how to send a string saying what output needs to be selected? I'm confused where you need help.
