* harbour/contrib/hbwin/Makefile
  + harbour/contrib/hbwin/hbolesrv.c
    + added inproc OLE server implementation. It allows to create OLE/ACTIVEX
      COM server in Harbour. Such OLE server allows can be used by programs
      written in any languages supporting OLE automation (also in other
      Harbour applications)
      User ole server code should be linked as DLL which later can be
      register in MS-Windows by regsvr32.exe program, i.e.:
         regsvr32 myolesrv.dll
      The OLE server code should contain DLLMAIN() PRG function which
      is executed just after loading OLE inproc DLL server as server from
      other application and also by regsrv32.exe during registration and
      unregistration procedure. It has to initialize at least OLE server
      ID and name usinf WIN_OleServerInit().
    + added new PRG function which intitialize OLE server:
      WIN_OleServerInit( <cClassID>, <cServerName>, ;
                         [ <hAction> | <oAction> | <bAction> | <sAction> ], ;
                         [ <lHashClone> | <lAcceptAll> ] ) -> <lServerActive>
      <cClassID> is registered OLE server class GUID

      <cServerName> is OLE server class name

      <hAction> is optional parameter with hash array containing messages
      and instance variables used by OLE server. The keys in hash array
      are strings with message names and values are actions. Codeblock
      and symbol items means that given message is a method call and
      any other value means that it's variable.
      By default the same hash array is shared between all objects
      created by registered server. It's important when hash array
      contains values which are neither codeblock nor symbol items
      so they are not used as method but rather as instance variables
      because such instance variables are shared between OLE objects.
      Setting 4-th parameter <lHashClone> to .T. causes that each
      objects receives it's own copy of <hAction> item so instance
      variables inside hash array are also local to OLE object.
      Alternatively programmer can use <bAction> or <sAction> to create
      seprate copy of hash array for each object, i.e.:
         bAction := {|| hb_hClone( hValue ) }
      When hash array contains symbol item (@funcName()) then when it's
      executed by OLE object message it's possible to access the hash
      array bound with given OLE object using QSelf() function. It maybe
      useful if hash array contains instance variables and programmer
      wants to access them.
      Please remember that using hash array which was initialized to keep
      original assign order by HB_HKEEPORDER( <hAction>, .T. ) before
      adding its items you can define strict message numbers (DISPIDs), i.e.:
         hAction := {=>}
         HB_HKEEPORDER( hAction, .T. )
         hAction[ "OPEN" ]  := @myole_open()     // DISPID=1
         hAction[ "CLOSE" ] := @myole_close()    // DISPID=2
         hAction[ "SAVE" ]  := @myole_save()     // DISPID=3
         hAction[ "LOAD" ]  := @myole_load()     // DISPID=4
         hAction[ "PRINT" ] := @myole_print()    // DISPID=5
      (see example in olesrv2.prg)

      <oAction> is optional parameter with Harbour object which is used
      as base for all newly created OLE objects. All messages (method and
      instance variables) supported explicitly by <oAction> object (except
      ONERROR message redirecting) are inherited by OLE objects. Each
      newly created OLE object uses the same <oAction> object so its
      instance variables are shared between all of them. If programmer
      wants to create separate Harbour object for each OLE object then
      he should use <bAction> or <sAction>, i.e.:
            bAction := {|| myClass():new() }

      <bAction> is optional parameter with codeblock executed when new
      OLE object is created. It should return hash array or Harbour object
      which will be used as base for newly created OLE object.

      <sAction> is optional parameter with function symbol. This function
      is executed when new OLE object is created and should return hash
      array or Harbour object which is used as base for newly created
      OLE object.

      If the 3-rd parameter is <oAction>, <bAction> or <sAction> then
      it's possible to also set 4-th parameter <lAcceptAll> to .T. and
      in such case <xAction> parameter is used in different way. Newly
      created OLE object accepts any massage names invoking for each
      of them EVAL() message which is sent to <xAction> with OLE message
      name inserted as the 1-st item to OLE object parameters.
      It allows to create OLE server which will accept unknown messages
      redirecting them to some other code, i.e.:
         if netio_connect( cServer,,, cPasswd )
            WIN_OleServerInit( cClassID, cServerName, @netio_funcExec(), .T. )
         endif
      initialize OLE server which redirects all messages to default netio
      connection establish by netio_connect().

      If 3-rd parameter is not given then all HVM functions becomes
      OLE methods and HVM memvars (public and private variables) are
      OLE object instance variables so they are shared with all OLE
      objects created by this interface. It works just like xHarbour.com
      OLE server described at
      http://xharbour.com/index.asp?page=add_on_oleserver&show_sub=7&show_i=1

    ; TODO: add support for MT RPC servers. Current implementation cannot
            be safely used in MT programs creating OLE objects and executing
            their methods simultaneously in different threads without
            additional user code which will serialize these operations.
    ; TODO: replace message handler API in WIN_AxGetControl()/
            __AxRegisterHandler() which uses only fixed method IDs
            and do not support method names with above one so user
            can easy create activex controls which support message
            names. This modificaiton will force updating user and 3-rd
            party code but IMO should be done. Current interface is
            simply too much limited to keep it.
    ; Possible TODO: add support for user defined fixed message numbers
                     (DISPIDs) which are not continuous small numbers so
                     users cannot easy use hash arrays with strict order.
                     Is such functionality necessary? Can someone with
                     ActiveX experience say sth about it?
                     Above implementation has undocumented feature:
                     it supports hash arrays with keys using numbers only
                     which can be used like in __AxRegisterHandler() but
                     I haven't decided yet I should keep, extend or remove
                     such functionality.

    Please make real life test.
    I do not have any practice with MS-Windows and OLE and most of above
    code I wrote using only documentation so I'm very interesting in real
    test results and user opinions about it. If some important functionality
    is missing then please inform me about it.
    BTW There are some 3-rd party activex implementation for [x]Harbour, i.e.
    xharbour.com or FiveWin ones. Maybe someone familiar with them can create
    PRG compatibility layer for Harbour. I cannot do that myself because I
    do not know that products and their PRG API used in OLE/COM/ActiveX
    implementations but if someone can describe it then I can help in such
    implementation.

    + added .DEF link files which are necessary to correctly export
      inproc OLE server DLL functions. It's possible that other compilers
      or even different versions of the same compilers may use different
      a little bit different .DEF files. I tested above with BCC5.5,
      MinGW 3.4.5 and OpenWatcom 1.8.

    + added example of NETIO-RPC OLE server code with Harbour (PRG) client.
      This server redirects all messages sent to its OLE objects to remote
      HBNETIO server as function calls. It understands the following
      messages:
         CONNECT()    - creates connection to the server, parameters like in
                        NETIO_CONNECT() and NETIO_GETCONNECTION() functions
         DISCONNECT() - closes current connection
         PROCEXISTS() - works like NETIO_PROCEXISTS()
         PROCEXEC()   - works like NETIO_PROCEXEC()
         PROCEXECW()  - works like NETIO_PROCEXECW()
         FUNCEXEC()   - works like NETIO_FUNCEXEC()
      All other messages are redirected directly to RPS server as function
      calls.
      CONNECT() message should be executed by client to create
      connection to the server. Each NETIO-RPC OLE object uses its own
      connection which should be initialized. If CONNECT() is executed
      more then once the current connection is closed.
      DISCONNECT() is executed automatically when OLE object is destroyed
      so it's not necessary to call it explicitly.
      Please use hbmk2 and olesrv1.hbp to compile OLE server. OLE inproc
      servers have to export some DLL entry functions which are defined
      in .def files which have to be passed to linker.
      Before client code can be tested the server has to be registered.
      The server can be registered in given MS-Windows system using
      regsvr32.exe command. To register the server use:
         regsvr32 olesrv1.dll
      and to unregister:
         regsvr32 /u olesrv1.dll

      and Visual Basic (BAS) clients.
      This server redirects all messages sent to its OLE objects to HVM
      functions and messages to HVM memver (public and private) variables
      This server should work as xHarbour.com OLE servers described at:
      http://xharbour.com/index.asp?page=add_on_oleserver&show_sub=7&show_i=1
      The server and clients code are nearly the same so users can easy
      compare them.

* <cServerName> is OLE server class name
*
* <hAction> is optional parameter with hash array containing messages
* and instance variables used by OLE server. The keys in hash array
* are strings with message names and values are actions. Codeblock
* and symbol items means that given message is a method call and
* any other value means that it's variable.
* By default the same hash array is shared between all objects
* created by registered server. It's important when hash array
* contains values which are neither codeblock nor symbol items
* so they are not used as method but rather as instance variables
* because such instance variables are shared between OLE objects.
* Setting 4-th parameter <lHashClone> to .T. causes that each
* objects receives it's own copy of <hAction> item so instance
* variables inside hash array are also local to OLE object.
* Alternatively programmer can use <bAction> or <sAction> to create
* seprate copy of hash array for each object, i.e.:
* bAction := {|| hb_hClone( hValue ) }
* When hash array contains symbol item (@funcName()) then when it's
* executed by OLE object message it's possible to access the hash
* array bound with given OLE object using QSelf() function. It maybe
* useful if hash array contains instance variables and programmer
* wants to access them.
* Please remember that using hash array which was initialized to keep
* original assign order by HB_HKEEPORDER( <hAction>, .T. ) before
* adding its items you can define strict message numbers (DISPIDs), i.e.:
* hAction := {=>}
* HB_HKEEPORDER( hAction, .T. )
* hAction[ "OPEN" ] := @myole_open() // DISPID=1
* hAction[ "CLOSE" ] := @myole_close() // DISPID=2
* hAction[ "SAVE" ] := @myole_save() // DISPID=3
* hAction[ "LOAD" ] := @myole_load() // DISPID=4
* hAction[ "PRINT" ] := @myole_print() // DISPID=5
* (see example in olesrv2.prg)
*
* <oAction> is optional parameter with Harbour object which is used
* as base for all newly created OLE objects. All messages (method and
* instance variables) supported explicitly by <oAction> object (except
* ONERROR message redirecting) are inherited by OLE objects. Each
* newly created OLE object uses the same <oAction> object so its
* instance variables are shared between all of them. If programmer
* wants to create separate Harbour object for each OLE object then
* he should use <bAction> or <sAction>, i.e.:
* bAction := {|| myClass():new() }
*
* <bAction> is optional parameter with codeblock executed when new
* OLE object is created. It should return hash array or Harbour object
* which will be used as base for newly created OLE object.
*
* <sAction> is optional parameter with function symbol. This function
* is executed when new OLE object is created and should return hash
* array or Harbour object which is used as base for newly created
* OLE object.
*
* If the 3-rd parameter is <oAction>, <bAction> or <sAction> then
* it's possible to also set 4-th parameter <lAcceptAll> to .T. and
* in such case <xAction> parameter is used in different way. Newly
* created OLE object accepts any massage names invoking for each
* of them EVAL() message which is sent to <xAction> with OLE message
* name inserted as the 1-st item to OLE object parameters.
* It allows to create OLE server which will accept unknown messages
* redirecting them to some other code, i.e.:
* if netio_connect( cServer,,, cPasswd )
* WIN_OleServerInit( cClassID, cServerName, @netio_funcExec(), .T. )
* endif
* initialize OLE server which redirects all messages to default netio
* connection establish by netio_connect().
*
* If 3-rd parameter is not given then all HVM functions becomes
* OLE methods and HVM memvars (public and private variables) are
* OLE object instance variables so they are shared with all OLE
* objects created by this interface. It works just like xHarbour.com
* OLE server described at
* http://xharbour.com/index.asp?page=add_on_oleserver&show_sub=7&show_i=1
