Hi John,

Thank you.I have win2003 SDK+vc++2008 EX installed in my machine.When I tried the winsamp.d in the example folder of dmd(ver2031):

/>coffimplib -f vfw32.lib
/>dmd winsamp.d gdi32.lib vfw32.lib winsamp.def
** also tried bud winsamp.d gdi32.lib vfw32.lib 

I got below error:

F:\laguangeD\WindowsApi-CMakeD\demo>bud winsampw.d -cleanup gid32.lib vfw32.lib

What's that?Was I missing something?
