I can add protection against multiple HVM initialization anyhow using the same HVM for client and server code introduces interactions between them which do not use OLE API, i.e. they will use the same static variables. In OS/2 this is a .dll definition at compile time, that is, INITINSTANCE clause inside .def file which tells the OS that the data segment has to be private for each process that attaches to that .dll. Hope this helps. Maurilio. PS. I'm sorry I haven't tested your serial routines under OS/2 yet, I simply don't have any spare time right now, but they build fine, at least. -- __ | | | |__| Maurilio Longo |_|_|_|| farmaconsult s.r.l. ___ Harbour mailing list (attachment size limit: 40KB) Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour

I thought it is more common to create some Harbour level object and share it via OLE server, thus making methods and properties of OLE object to be methods and properties of Harbour object (instead of public functions and memvars of Harbour application).

Probably each of us likes to tests the code anyhow in the past I had to create some bigger peaces of code without any way to make real tests until I finished nearly whole project and believe me it's possible. In this particular case the code is relatively small ~500 lines. The most amazing is the fact that I've just compiled it and executed using WinXP machine in my office and it works correctly without any modifications. I can compile the .PRG client and server example from xHarbour.com OLE server page. I only have to link at least one of components (server or client) statically because both linked dynamically with the same harbour.dll shares the same HVM so server fails inside hb_vmInit(). I can add protection against multiple HVM initialization anyhow using the same HVM for client and server code introduces interactions between them which do not use OLE API, i.e. they will use the same static variables. I'm interesting if it's possible to link both client and sever dynamically with xhbdll.dll using xHarbour.com. If yes and users need it then I can also emulate it.

I thought it is more common to create some Harbour level object and share it via OLE server, thus making methods and properties of OLE object to be methods and properties of Harbour object (instead of public functions and memvars of Harbour application). I also think that opening whole HVM is limited only to some rather small subset of possible applications and probably more restrictive servers which make public only some well defined set of methods using object or hash array will be more popular. But it's not my job to force how user will use it. The xHarbour.com compatible interface is only one of possible choices. best regards, Przemek ___ Harbour mailing list (attachment size limit: 40KB) Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour

Hi Przemek, Very nice, count me to those who are eagerly awaiting it. (even if in not yet fully cooked state) Thank you. There are some things which should be added/modified in hbmk2.

Why HBMK2 ignore -*flag=params if params does not start with - character? Can you eliminate this restruction? No problem to add support for .def files. I never had to use them so far, so maybe it will need a few iterations to get right. As for flag option, I'd prefer to make the filtering, otherwise it's very easy to deeply mess up some command lines, and can make hbmk2 fall out of control of things. The general concept is that hbmk2 deals with assembling the major components of the cmdline and user user is given a chance to supply additional flags only. Hence the name -?flag= and ?flags= of these options. The next thing is building DLL and passing some link time parameters which are used with standalone EXE files. It would be nice if we can have an option to enable support for -gt and similar switches when -hbdyn option is used, i.e. this option can be extended to -hbdyn[vm] and -hbdynvm will enable support for startup options specified in .c temporary file used for normal executable files and also harbour core libraries in inked library list. If only -hbdyn is used then Harbour libraries should nor be linked by default. Do you think it possible to add it? It seems fine to me. Same applies as above, I'm in the dark about OLE servers, so I'll either ask, or pls tell me what's specifically missing/needed. So far I understand -hbdynvm would disable -nohblib option. Can you help finding out, what's the best 1 description for -hbdynvm mode? -hbdyn is create dynamic library. Maybe create dynamic library with Harbour VM?
