How to combine (or use) SDK dll into Fivewin HB/XHB?

[kim yong woo]

Dear Sirs,

Came again to get help of specialists..

Compiled open1.prg with Harbour 32 bit, and MSVC 2013 Express mentioned above.
In MSVC, there was "Previous definition" Error found..

E:\vs2013exp\VC\INCLUDE\sal.h(455) : see previous definition of '_COM_Outptr_'
E:\vs2013exp\VC\INCLUDE\sal.h(352) : see previous definition of '_Out_opt_'
E:\vs2013exp\VC\INCLUDE\sal.h(314) : see previous definition of '_In_'

Deleted thos 3 line of #define(#define _COM_Outptr_,#define _Out_opt_,#define _In_)
And, compiled.

There was following error

Code: Select all

open1.prg(60) : error C2664: 'HRESULT (const IID &,const IID &,LPVOID *)' : cannot convert argument 2 from 'const IID *' to 'const IID &'
        Reason: cannot convert from 'const IID *' to 'const IID'
        No constructor could take the source type, or constructor overload resolution was ambiguous
open1.prg(75) : error C2664: 'HRESULT MyCoCreateInstance(LPCTSTR,const IID &,IUnknown *,const IID &,LPVOID *)' : cannot convert argument 2 from 'const CLSID *'
to 'const IID &'
        Reason: cannot convert from 'const CLSID *' to 'const IID'
        No constructor could take the source type, or constructor overload resolution was ambiguous
 

Following is around line 60 of open1.prg

Code: Select all

  hr = GetClassObject(rclsid, &IID_IClassFactory, (LPVOID *)&pIFactory);

  if (!SUCCEEDED(hr))
    return hr;
 

Following is lines around 75

Code: Select all

HB_FUNC( IKTPCBIZX_NEW )
{
   IKTPCBizX* pKTPCBiz;
   //HRESULT hr;
   MyCoCreateInstance("KTOpenAPI.dll", &CLSID_KTPCBizX, 0, &IID_IKTPCBizX, (void**)&pKTPCBiz);
#ifndef _WIN64
   hb_retnl( (long)pKTPCBiz );
#else
   hb_retnll( (long long)pKTPCBiz );
#endif
}

LPWSTR UTF8toUTF16( LPCSTR utf8 );
 

In compiling with Borland, there was no problem on MyCoCreateInstance(), -IKTPCBizX_New,
And, error happend with IKTPCBizX_LogIn.

But, in compiling with MSVC, there was error in MyCoCreateInstance(), -IKTPCBizX_New,...

Please kindly advise to me..

Thanks.

It is a problem of compiling in C or in C++ mode, the code is for compile in C mode.
remove the -TP option where call cl.

in buildh32.bat from FwiveWin\samples there is:

Code: Select all

"%VCINSTALLDIR%"bin\cl -TP -W3 -c /GS- /I%hdir%\include /GA %1.c

substitute with

Code: Select all

"%VCINSTALLDIR%"bin\cl -W3 -c /GS- /I%hdir%\include /GA %1.c

Dear Sirs,

The KTOpenApi.prg was identical with the source compilored with Mr.AntoninP.
(without #define area)

But, there was no problem with his compilation, and error in mine.

Can this difference be generated from difference in rc.exe?
My rc.exe detail was as following..

Code: Select all

Microsoft (R) Windows (R) Resource Compiler Version 6.2.9200.20789
Copyright (C) Microsoft Corporation.  All rights reserved.

Kim,

But, there was no problem with his compilation, and error in mine

What is exactly the error ?

Were you able to contact Daniel ?

[AntoninoP]

Dear Mr.Woo,
I am really sorry, the solution is very simple,
First register their DLL ( KTOpenAPI.dll) as followings.

Code: Select all

regsvr32 KTOpenAPI.dll

then use a code like this:

Code: Select all

#include <fiveWin.ch>

proc main()
   LOCAL IKTPCBizX, cTest
   CoInitialize(0)
   
   IKTPCBizX := win_OleCreateObject("{16AB1B2A-A22E-4FAC-92CB-84102DF5CE3D}","{5C41C7F0-BE5D-4819-A086-E13B80666454}")
   //                                ^^ ClassID  KTPCBizX                      ^^ IID of   IKTPCBizX
   
   ? 1,IKTPCBizX
   if .not. empty( IKTPCBizX )
      ? 2
      cTest := IKTPCBizX:Login( ;
               /*nServer*/666, ;
               /*sAuthKey*/"Example", ;
               /*sLoginID*/"Antonino",  ;
               /*sLoginPwd*/"password")
      ? 3, cTest
   else
      ? "error:"+win_oleErrorText()
   endif
   ? "exit"
return

Regards,
Antonino
