Silvio,

I trying to convert old program ( 16 bit) to xharbour and now my xmate make me errors :

::nWidth := pBmpWidth ( ::hBmp )
::nHeight := pBmpHeight( ::hBmp )

these func exist or not ?

Use:

::nWidth := nBmpWidth ( ::hBmp )
::nHeight := nBmpHeight( ::hBmp )

CLIPPER xVScrll() // ( hWnd, wRows, nHRow, nRows, lHeader, nHeader )
{
   HWND hWnd     = _parni( 1 );
   WORD wRows    = _parni( 2 );
   int  nHRow    = _parni( 3 );
   int  nRows    = _parni( 4 );
   HDC hDC     = GetDC( hWnd );
   RECT rct;
   BOOL bHeader = _parl( 5 );
   WORD nHeader = _parni( 6 );

   GetClientRect( hWnd, &rct );

   if ( bHeader )
      rct.top    = nHeader + 1;
      rct.bottom = ( nHRow * nRows ) - 1;
      ScrollWindowEx( hWnd, 0, -( nHRow * wRows ), 0, &rct, 0, 0, 0 );
      ReleaseDC( hWnd, hDC );
}

//----------------------------------------------------------------------------//

CLIPPER xHScrll() // ( hWnd, nCols, nLeft, nRight )
{
   HWND hWnd     = _parni( 1 );

   GetClientRect( hWnd, &rct );

   if ( nLeft ) {

   }

   if ( nRight ) {

   }


   ScrollWindowEx( hWnd, wCols, 0, 0, &rct, 0, 0, 0 );


   ReleaseDC( hWnd, hDC );
}

//----------------------------------------------------------------------------//



and this another

Code: Select all  Expand view

#include "WinTen.h"
#include <Windows.h>
#include "ClipApi.h"

void pascal Dos3Call( void );

#define SUBSTDRIVE 0x8000
#define NETDRIVE   0x1000

//----------------------------------------------------------------------------//

CLIPPER cDrives()   // It returns an string with all the valid drives ids
{
   BYTE b,c;
   BYTE drives[ 26 ];
   BYTE nDrives = 0;
   c = 0;

   for( b = 0; b < 26; b++ )
      drives[ b ] = ' ';

   for( b = 0; b < 26; b++ )
   {
      // drives[ b ] = ' ';

      _AX = 0x4409;
      _BL = b;
      Dos3Call();

      if( ! ( _FLAGS & 1 ) )
        {
         drives[ c++ ] = 'A' + b - ( b >= 1 );
         nDrives++;
      }
   }

   _retclen( drives+1 , nDrives - 1);
}

Can You help me ...

Silvio,

The first functions are quite easy. Just add "hb" before the "_" of the extend system functions. Please review Harbour C source code RTL functions to get lots of examples.

Regarding the second one, you have to implement it using a Win32 API call as Dos3Call() is not supported in Win32.
