refresh code from perforce so that it reflects most recent version of code

hi,

i m a novice programmer in VBScript. But i am facing a major problem regarding some work related to perforce. Actually i am working on MSI Installers and each time i create the installer i need to check that the files that i use for creating the installer should be the most latest version. that means i need to check out the code from perfoce(where all the files are present) and then use those files to create the MSI Installer. So for that i need to write a .vbs script. can anyone help me out regarding that?

is there any other way to get that (other than VBScript)? any suggestions are fairly welcome.

thanks a lot.
