Hello every experts!

I have limited experience with Fivewin.

I am trying to build-up telephone CID(Caller Identification) program with SDK published by phone company.

How Can I use this dll in FWH harbour/xHarbour?
Pleae help me...!

Attached my target DLL(KTOpenAPI.dll) as followings.
http://pharmalink.kr/images/K.zip

They mentioned to register their DLL ( KTOpenAPI.dll) as followings.
-----------------------------------------------------------------------------------
regsvr32 KTOpenAPI.dll

And and in MSC Sharp sample were as followings

Main.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;

namespace KTOpenAPICSharpSample
{
static class Program
{
/// <summary>

Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new OpenAPI());
}
}
}

It is a very hard task, I am not sure if there is a tool that create COM interface for Harbour automatically, if it does not exist, i could create it

For now, what you can do is look at http://www.codeproject.com/Articles/632 ... in-plain-C
That personally combine with http://www.codeproject.com/Articles/184 ... teInstance (I prefer don't register dll that are not essential)

So, following the fist link (point 3) you can create KTOpenAPI.h and KTOpenAPI_i.c, then use them in code like this: Here is missing the code to unload the dll.

If I run it, it says that KTPSock.dll is missing...

Thanks so much for your supports, and sorry for missing KTSock.dll

KTSock.dll is included in following link.

After following your advice, I will post results.

Thanks.. Thanks...

Antonino,

Great code!

Thank you for your great help!

Hello

a simple tip

harbour support a pointer parameter to communicate between high and low level, is very useful to avoid #define _win64

example
use hb_rerptr( (void*) pValue ) to send at HIGH LEVEL
use hb_parptr( nParams ) to recibe in LOW LEVEL

Antonino, I'm sure it would be a great and appreciated tool to have

Thank you, I don't saw it, theoretically (and practically) the int has always the same length of pointer, so I could use hbparni and hbretni.
I made a sin of copy and paste from FiveWin's source code

When FWH was built those functions did not exist

Later on we could have modified FWH code to use them, and we don't
discard to do it in the future.

Anyhow FWH current code works very well

but its true that we could remove those ifdefs and use those functions

Mr Antonino

Do you mean to say the sizes of int and pointer on 64-bit OS also is the same?

This is what I thought till now:
On 32-bits, sizes of int, long and pointer are all 4 bytes only.
But on 64-bits size of int is still 4 bytes where as long and pointer are 8 bytes.
Therefore size of int is not the same as size of pointer on 64-bits. So we can not us hb_parni and hb_retni for pointers on 64-bits.

I seek clarification from experts like, Antonio, Daniel and AntonioP to please check and give their opinion on this for my benefit as well for the benefit of all who learn from this thread.

Here is a simple example to test those sizes.

To check it for 64 bits, please use FWH 64 and do build64.bat sizes:

int returns 4 and a pointer returns 8:

sizes.prg

int returns 4 and a pointer returns 8:

Yes.

I request guidance from the experts on using hb_retptr()

I have in my C Code
HBITMAP hBmp;
I want to return the value of handle HBITMAP.

Should i write
hb_retptr( ( void * ) &hBmp ) ?
If not what is the correct way?

This should be fine:

hb_retptr( ( void * ) hBmp );

Apologies for everyone, I checked, and you are right:

size of int depends by the compiler, on windows it is 32bit even for 64bit application

even the strandard says: "Plain ints have the natural size suggested by the architecture of the execution environment",


Anyway I mus say that do hb_retptr and hb_retni/hb_retnl/hb_retnll is not the same
try this: it write: so we can not substute hb_parn*/hb_retn* with hb_parptr/hb_retptr because they are 2 different things

Dear Mr.Antonio Linares

Would you kindly upload or email to me KTOpenAPI.h and KTOpenAPI_i.c?

I am not a expert to create those things.

Thanks.
