Hi. i've installed tango but i'd been strugling to get the sys.win32 stuff 
happening. I keep getting this error when i build...

C:\Documents and Settings\chris\Desktop\dproj>bud Project1.d -full
OPTLINK (R) for Win32  Release 7.50B1
Copyright (C) Digital Mars 1989 - 2001  All Rights Reserved

cjl\graphic.obj(graphic)
 Error 42: Symbol Undefined _SetDIBitsToDevice 48

The source line is this..

        int err = SetDIBitsToDevice(
            dc, x, y, fwidth, fheight,0, 0, 0,
            fheight, fpixels.ptr, &fheader, DIB_RGB_COLORS
            );

And it seems to do the same with all the gdi functions. Anyway I tried 
this..

version(build) { pragma(link, usergdi32); };

to get bud to link in usergdi32, but CreateWindowEx, and other non gdi 
functions are working ok so i dont think thats the problem.

And thanks everyone who's been helping me, its very much apreciated,

usergdi32.lib is linked by default for Tango/Win32, so something else is 
going on.  I'd guess that perhaps the windows library that contains the 
implementation for this function is snot being linked.  The function 
lives in gdi32.lib, so try putting that in the pragma instead.  Tango's 
usergdi32.lib only contains constants and such.  The actual windows code 
lives elsewhere.

Yeah that has done the trick.. thanks.
