I'm trying to find a way to get to the _GlobalToLocal VFP API function directly from VFP, i.e. without the need for a C/C++ compiler. Unfortunately this is not one of the VFP API functions exposed by FOXTOOLS.FLL. Please note the the similar Win32API functions for converting coordinates between the Windows desktop and a window's interior are NOT what I'm after, because these do not use the same intra-window coordinate system as VFP. The difference is that VFP's toolbar docking effects are not recognized by the Win32API functions (ClientToScreen and ScreenToClient). There seems to be no easy, general way to do this coordinate transformation with any standard VFP-callable functions or PEMs. If you know of a DLL or FLL that exposes _GlobalToLocal, I would really appreciate a tip about how to find it.
