To Antonio: Harbour OLE implementation

[vailtom]

Please, Antonio Linares can perhaps give us a suggestion about this ...
http://lists.harbour-project.org/piperm ... 19190.html

Many thanks,
Vailton

[Rossine]

Hello Antonio,

would be possible to implement these changes ?

[Antonio Linares]

Vailton, Rossine,

Those changes are welcome and will not break FWH code. They can move from numers to pointers. No problem about it.

FWH uses standard Class TOleAuto, so if Harbour code gets improved, its fine for FWH

[Rossine]

Hello Antonio,

Could we change that now for the next version ?

[Rossine]

Hello Antonio,

This error, still persists:

[ENDERROR]

It is possible to reconcile with the activex FWH Harbour to FWH 9.05 version ?

[Rossine]

Hello Antonio,

Welcome to your home.

You can adjust the activex from fwh to work with latest version of the harbour ?

Rossine,

Please use this function to generate a Harbour pointer:

Code: Select all  Expand view

HB_FUNC( RETPTR ) // nValue --> Harbour_Pointer
{
   hb_retptr( ( void * ) hb_parnl( 1 ) );
}
 

Then modify this in Class TActiveX:

Code: Select all  Expand view

::oOleAuto = TOleAuto():New( RetPtr( ActXPdisp( ::hActiveX ) ) )

I use fwh 9.04 + bcc (svn rev.11320).

Any more suggestions ?

[Antonio Linares]

Rossine,

Please try this code:

Code: Select all  Expand view

#pragma BEGINDUMP

#include <hbapi.h>
#include <windows.h>

LPSTR hb_oleWideToAnsi( BSTR wString );

HB_FUNC( STRINGFROMCLSID )

   LPSTR * psz;
 
   StringFromCLSID( ( REFCLSID ) hb_parnl( 1 ), &pOleStr );
   hb_retc( psz = hb_oleWideToAnsi( pOleStr ) );
   hb_xfree( psz );
}

#pragma ENDDUMP

::oOleAuto = TOleAuto():New( STRINGFROMCLSID( ActXPdisp( ::hActiveX ) ) )

Hello Antonio,

I updated the version of the harbour to 11.365 and now has changed message, see:

I test of three ways:

Code: Select all  Expand view

::oOleAuto = TOleAuto():New( ActXPdisp( ::hActiveX ) )
...
::oOleAuto = TOleAuto():New( RetPtr( ActXPdisp( ::hActiveX ) ) )
...
::oOleAuto = TOleAuto():New( STRINGFROMCLSID( ActXPdisp( ::hActiveX ) ) )
...
 

strange

Here activex return "O":

Code: Select all  Expand view

   oActiveX = TActiveX():New( oWnd, "Shell.Explorer" )

   msgstop( valtype( oActiveX ) )
 

...and this:

Code: Select all  Expand view

memowrit( "dump.txt", hb_dumpvar( oActiveX ) )
 

...return:

How to fix this ?

[Antonio Linares]

Rossine,

Yesterday a TOleAuto fix for Harbour was published.

Please do a checkout and try with the new one, thanks

[Rossine]

Hello Antonio,

I tested with the rev. 11383 today, and it occurs error. Tested the three ways you said above.

What to do

[toninhofwi]

Hi friends,

This works:

Code: Select all  Expand view

  #include "winapi.ch"
   local oWindow, oActiveX
   DEFINE WINDOW oWindow FROM 0,0 to 400,300 TITLE "Flash Player"
   WIN_AxInit()
   oActiveX = WIN_AxGetControl( CreatePtrActiveX( 0, "AtlAxWin", "ShockwaveFlash.ShockwaveFlash.1", nOR( WS_CHILD, WS_VISIBLE ), 0, 0, 200, 200, oWindow:hWnd, 0 ), nil )
   ACTIVATE WINDOW oWindow ON INIT oActiveX&#058;LoadMovie( 0, "c:\flash.swf" )

Code: Select all  Expand view

#pragma BEGINDUMP

#include "windows.h"
#include "hbapi.h"

extern HINSTANCE _hInstance;

HB_FUNC( CREATEPTRACTIVEX )
{
   hb_retptr( CreateWindowEx(
      hb_parnl( 1 ),
      hb_parc( 2 ),
      (LPCTSTR)ISNIL( 3 ) ? ""                  : hb_parc( 3 ) ,   // cProgId
      (DWORD)  ISNIL( 4 ) ? WS_OVERLAPPEDWINDOW : hb_parni( 4 ),   // style
               ISNIL( 5 ) ? CW_USEDEFAULT       : hb_parni( 5 ),   // nLeft
               ISNIL( 6 ) ? CW_USEDEFAULT       : hb_parni( 6 ),   // nTop
               ISNIL( 7 ) ? 300                 : hb_parni( 7 ),   // nWidth
               ISNIL( 8 ) ? 300                 : hb_parni( 8 ),   // nHeight
               ISNIL( 9 ) ? HWND_DESKTOP        : (HWND) hb_parnl( 9 ),    // oParent:handle
               ISNIL( 10 ) ? 0                   : (HMENU) hb_parnl( 10 ),  // Id
               _hInstance,
