Hi Peter,

I am having some initial difficulties that hopefuly can be overcome. Some questions:

In my case Team 1 will develop an exe and provide some dlls and an ocx. (By the way, can the the VFP dlls be inside the MoleBox package? I mean vfp9r.dll and vfp9renu.dll? That would open other possibilities.) Team 2 will only provide an app file. Do you know how file 2 must be prepared with Molebox since it does not include an exe, only an app file? Do files provided by team 2 need to be included in the same exe package as those provided by team 1?

In general I would prefer a single exe file that extracts other files [by using strtofile(filetostr(myapp.app_),myapp.app)] in order to make sure file versions are always synchronized.

Another question: what do you mean by "same map"?

Thanks,

Alex

Both teams need to use the same encryption key. When the two files are put together in the same map, the EXE will find the referenced file, will know how to decrypt it and all will be fine.

Both teams need to use the same encryption key for all files. (All files will be encrypted seperately.) When ALL files are put together in the same map, the EXE will find all referenced files, will know how to decrypt them and all will be fine.
