Dave,

Please add this code at the beginning of babudll.prg:

extern LoadLibrary, FreeLibrary, AnsiToWide

Please modify buildhd.bat to use gtgui.lib instead of gtwin.lib
and add this library too:

echo %bcdir%\lib\psdk\msimg32.lib + >> b32.bc This one !!!
echo %bcdir%\lib\psdk\rasapi32.lib, >> b32.bc

Dave,

Please add this library to buildhd.bat and try it again, thanks:

echo %hdir%\lib\rddfpt.lib + >> b32.bc
echo %hdir%\lib\hbwin.lib + >> b32.bc // this one !

Antonio,

Added the line to the batch file and it creates the dll, however when I compile babu.prg and run
it I am getting :

An exception error(C0000005) occurred during DllEntryPoint or DllMain in module:
c:\fwh\samples\babudll.dll


Thanks

Dave,

Where have you downloaded maindll.c from ?

How have you compiled maindll.c ? What compiler flags have you used ?

Antonio,

I used the latest maindll.c from the harbour-1.0.1\source\vm\maindll.c

I can post it if needed:

I added this to my buildhd.bat

%bcdir%\bin\bcc32 -c -D__EXPORT__ -I%hdir%\include;%bcdir%\include -L%bcdir%\..\lib maindll.c

Thanks

Vailton,

I appreciate the info, however I am not sure what to do with it.

Do I need to change my batch file from __EXPORT__ to HB_DYNLIB ?

Thanks

When you compile a .DLL should not use the macro __EXPORT__ as it is in changelog, this was changed.
Maybe this could be it mixed in the command line you posted above.

Dave,

> Do I need to change my batch file from __EXPORT__ to HB_DYNLIB ?

Yes

Once the DLL is built, please do:

impdef.exe YourDll.DEF YourDll.DLL

and check the contents of YourDll.DEF. It is an ascii file that shows what symbols are exported from the DLL.

Antonio,

Got this in mydll.def

LIBRARY BABUDLL.DLL

EXPORTS
__DbgWndProc @1 ; __DbgWndProc
__WndProc @2 ; __WndProc
___CPPdebugHook @3 ; ___CPPdebugHook

Not sure what to do next.

Thanks

Dave,

These lines should be inside the DEF file:

DllEntryPoint @894 ; DllEntryPoint
HBDLLENTRY @895 ; HBDLLENTRY
HBDLLENTRY1 @896 ; HBDLLENTRY1
HBDLLENTRY2 @897 ; HBDLLENTRY2

Those numbers can be different.

If you don't have them, then it means that maindll.obj is not being properly built.

Re: Creating a LIB or DLL

Dave,

Please make these changes in maindll.c, and compile it again and build the DLL:

BOOL WINAPI __export DllEntryPoint( HINSTANCE hInstance, DWORD fdwReason, PVOID pvReserved )

LONG PASCAL __export HBDLLENTRY( char * cProcName )

LONG PASCAL __export HBDLLENTRY1( char * cProcName, LONG pItem )

LONG PASCAL __export HBDLLENTRY2( char * cProcName, LONG pItem1, LONG pItem2 )

Re: Creating a LIB or DLL

Antonio,

Like:

HB_EXPORT BOOL WINAPI DllEntryPoint( HINSTANCE hInstance, DWORD fdwReason, PVOID pvReserved )

to

BOOL WINAPI _export DllEntryPoint( HINSTANCE hInstance, DWORD fdwReason, PVOID pvReserved )

Also

You have
__export

should I use?
_export


Correct?

If so still have same


Thanks

HB_EXPORT BOOL WINAPI DllEntryPoint( HINSTANCE hInstance, DWORD fdwReason, PVOID pvReserved )
{
   HB_TRACE( HB_TR_DEBUG, ("DllEntryPoint(%p, %p, %p)", hInstance, fdwReason,
             pvReserved ) );

   HB_SYMBOL_UNUSED( hInstance );
   HB_SYMBOL_UNUSED( fdwReason );
   HB_SYMBOL_UNUSED( pvReserved );

   switch( fdwReason )

           break;

      case DLL_PROCESS_DETACH:
           hb_vmQuit();

   }

   return TRUE;
}

HB_EXPORT LONG PASCAL HBDLLENTRY( char * cProcName )
{
   hb_itemDoC( cProcName, 0, 0 );

   return 0;
}

HB_EXPORT LONG PASCAL _export HBDLLENTRY1( char * cProcName, LONG pItem )
{
   hb_itemDoC( cProcName, 1, ( PHB_ITEM ) pItem, 0 );

   return 0;
}

HB_EXPORT LONG PASCAL t HBDLLENTRY2( char * cProcName, LONG pItem1, LONG pItem2 )
{
   hb_itemDoC( cProcName, 2, ( PHB_ITEM ) pItem1, ( PHB_ITEM ) pItem2, 0 );

   return 0;
}

Dave,

Just to be sure that HB_EXPORT gets properly translated, better replace those lines as I have explained you and compile it again.
