Where are MoveTo, GetTextExtent, DrawMasked, DrawBitmap ?

[concentra]

Antonio, when I try to link a program with FW, Harbour and MinGW, it states that the folowing functions are missing :
MoveTo, GetTextExtent, DrawMasked, DrawBitmap and MaskRegion.
Where can I find them ?

[Antonio Linares]

Concentra,

Are you calling FWH MoveTo() or directly calling Windows API MoveTo() from C code ?

[concentra]

I am trying to compile/link Manuel Mercado's TsBrowse 9 with FW + Harbour + MinGW.
Part of this is compiling a C program that calls MoveTo.
The part of the code that does it is

Code: Select all

static void GoToPoint( HDC hDC, int ix, int iy )
{
   #ifdef __FLAT__
      POINT pt;
      MoveToEx( hDC, ix, iy, &pt ) ;
   #else
      MoveTo( hDC, ix, iy );
   #endif
}

[[]]

[Antonio Linares]

Add these lines to the top of your code, below #include <Windows.h>

Code: Select all

#ifdef __GNUC__ 
   WINBASEAPI BOOL WINAPI MoveTo( HDC, int, int );
   ... others used
#endif
 

[concentra]

Adding that lines i still get:

Code: Select all

../TSBFUNCS.o:TSBFUNCS.C:(.text+0x94): undefined reference to `MoveTo(HDC__*, int, int)@12

I managed to add a source code for MoveTo I found in other place and it linked, but I don't know if it works yet.

Code: Select all

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

DWORD MoveTo( HDC hDC, int x, int y )
{
   POINT pt;
   DWORD dw;

   MoveToEx( hDC, x, y, &pt );

   dw = pt.x + ( pt.y >> 16 );
   return dw;
}

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

I was unable to test yet because parameters order changed from v7 to v9 and I need to manage this before I can test.

[Antonio Linares]

Yes, it is right, as MoveTo() does not exist on Windows 32 and 64

[concentra]

Antonio, In order to link, I also needed to include the source of DrawMasked(), DrawBitmap() from \FWH\source\winapi\bmpdraw.c and MaskRegion() from \FWH\source\function\fwbmp.c.

Wasn't this to be in fivehg or fivehgc libs ?

[Antonio Linares]

What errors do you get from the linker ?

[Antonio Linares]

Please post the complete source code of TSBFUNCS.C

[concentra]

Antonio, this a modified version of TsBrowse 9 that is in http://code.google.com/p/fivewin-contri ... loads/list
In the end, the functions I copied from other source files are commented.
If I uncomment that functions the application links and TsBrowse runs, apparently Ok.
