bugs FWH64

[lucasdebeltran]

Antonio,

In FWH64, class Twebcam is not included.

Also, testing samples\testrtf causes a GPF.

Thank you much.

Antonio,

This is the hb_out.log when attemping to use RICHEDIT under FWH64:

Lucas,

Thanks for the feedback, I am going to review it asap.

I am currently completing my tests on the printer preview enhancements that Armando and Elvira requested and we have implemented

[Antonio Linares]

Lucas,

This seems to be the fix

Code: Select all | Expand

HB_FUNC( REGETOLEINTERFACE )
{
     #ifdef _WIN64
      hb_retl( SendMessage( ( HWND ) hb_parnll( 1 ),
                            EM_GETOLEINTERFACE, 0, ( LPARAM ) &predoc->preole ) );
   #else                         
      hb_retl( SendMessage( ( HWND ) hb_parnl( 1 ),
                            EM_GETOLEINTERFACE, 0, ( LPARAM ) &predoc->preole ) );
   #endif
}

the WIN64 part was missing. You can test it adding it to the PRG in a #pragma BEGINDUMP ENDDUMP section

[lucasdebeltran]

Antonio,

I tested this:


#pragma BEGINDUMP

#include "windows.h"
#include "wininet.h"
#include "hbapi.h"
#include "richedit.h"
#include <richole.h>

HB_FUNC( REGETOLEINTERFACE )
{

#ifdef _WIN64
hb_retl( SendMessage( ( HWND ) hb_parnll( 1 ),
EM_GETOLEINTERFACE, 0, ( LPARAM ) &predoc->preole ) );
#else
hb_retl( SendMessage( ( HWND ) hb_parnl( 1 ),
EM_GETOLEINTERFACE, 0, ( LPARAM ) &predoc->preole ) );
#endif
}


#pragma ENDDUMP


But I can´t compile:


msvc64.prg(155) : error C2065: 'predoc' : undeclared identifier
msvc64.prg(155) : error C2227: left of '->preole' must point to class/struct/union/generic type
type is ''unknown-type''


Thanks!.

[Antonio Linares]

Lucas,

Yes, sorry, you can not test it. I will email you the modified lib, thanks

[lucasdebeltran]

Antonio,

Thank you. Also, please include class tWebcam.

I do the test and I will inform you.

[Antonio Linares]

Lucas,

The bug you reported me regarding RichEdit made me realize that there is code in FWH that has not been properly adapted to 64 bits:

Everytime we use the extend system to send or receive a handle, we have to use hb_parnll() and hb_retnll(). This is due to the fact that handles in WIN64 can be larger than in WIN32, so I have started searching for all of them and checking that they are fine. Up to now I was most focused on made FWH 64 bits apps work properly and missed that important part too.

I have already modified many FWH C files to properly use hb_parnll() and hb_retnll(). I have not finished with all of them, but I prefer to make the changes progressively in case that some code could bring a problem. In fact, I think that everytime we supply a HWND, HDC, HBITMAP, HBRUSH, HFONT, etc (any handle) we could simply call hb_parnll() even for 32 bits apps, but I am not sure yet 100% if this could have any side effect. Same applies for hb_retnll().

So on a first stage the idea is to inspect all the code, locate places where those handles are not properly managed in 64 bits and once that process is completed, we could consider to call hb_parnll() always (though that just would simplify the source code but would not benefit our apps).

[Antonio Linares]

Lucas,

Once FWH 13.07 is published, I would appreciate to locate those places where calls to hb_parnll() and hb_retnll() are missing, in case we may be missing some of them.

Right now is useless as I have already modified many of them, that in 13.06 are unchanged.

[lucasdebeltran]

Antonio,

So can you please send me to my gmail email the fixed 13.06 libs to work with Richedit?.

We will continue testing the application and providing you feedback.

Bitmaps seems to be working fine.

And please, what about TWebCam class?.

Thank you.

[Antonio Linares]

Lucas,

Class TWebCam was simply missing from the FWH 64 makefile. I am rebuilding FWH 64 to include it and I will send it to you.

In the meantime, if you add the source code of the Class TWebCam to your PRG, then it should work fine.

[lucasdebeltran]

Antonio,

With the new libs you sent to me, TWebCam is fixed. It is neccesary to include Vfw32.lib, so build64.bat should be modified as:

echo %vcdir%\lib\vfw32.lib >> msvc.tmp


But the GPF with RichEdit is still happening.

samples\testrtf.prg causes this hb_out.log:

By the way, samples\winxp\WindowsXP.Manifest64 is missing.

Sorry about the bad news

Thank you.

[Antonio Linares]

Lucas,

thanks for your feedback, I was expecting it, as I did not include in the libs that I sent you all the changes that I did later on on richedit.

I am solving an issue with FWH 64 (testing on Windows 8, as there are some internal changes between Windows 7 and 8 ) and then I will be ready to send you a more recent libs that should work fine

[lucasdebeltran]

Antonio,

Any news please?.


Thanks.

[Antonio Linares]

Lucas,

I have succesfully built Harbour and FWH 64 using VS2012 and it is working fine

Could you upgrade to VS2012 C Express ? For us it is much more complex to support multiple versions, and I think VS2012 is a very good version to use. I can email the libs to you and you try it on VS2010 (I don't know yet if they are compatible, probably), thanks
