I am currently contracted to US Navy to develop a 1st ever Windows version of their medical management system. All prior versions have been FoxPro for DOS. Currently they have provided me with VFP 3.0b to begin development. My question is "If I use the DBC in VFP 3 will it easily convert to the DBC in VFP5 and if can be converted will it then allow multiple developers to work with the container?" So far I have developed many of the menu forms/formsets but I am avoiding the data manipulation forms because of the inability of VFP3 to allow multiple developers to use the DBC.
