No problem as long as the classes are closed (issue a CLEAR ALL & RELEASE ALL from the VFP command window). The downside to this is that only one programmer can checkout the class (or form). Some of our classes are written in PRG files, instead of VCXs, so that we can actually do multiple checkouts of classes.

In VSS; just make sure that you are pointing to the correct database. By default, VSS creates a local database in the PC it was installed. So if your VSS database is in the network; open the VSS in the local PC and under File->Open; Browse to the correct network VSS database. Of course; you need to make sure that you have a userid in the network VSS to be able connect to the network VSS database.

In VFP6 or 7, you can actually set the Text Generator in Tools->Options->Project which supposedly converts binary files (ie VCX/SCX) to text but I heard there are problems checking in/out converted binary files to VSS, so I never bothered using it.
