Hi!

Cetin, multi-threaded DLL means for VFP that you can make VFP COM object that could be called in multi-threaded mode. From inside of the VFP you cannot do multi-threading without external help from some tools.

Non-VFP EXE you can run using API function ShellExecute(), that also have a parameter to hide app window, however, it does not always help because many applications have their own system of controlling application windows. When EXE is VFP EXE application, you can hide it before starting just by putting 'SCREEN=OFF' in the config.fpw file, and then include that config file into that exe or run EXE using that config file.
