The Windows headers that come with Phobos are extremely incomplete. Try the WindowsApi bindings project instead: http://dsource.org/projects/bindings/wiki/WindowsApi

That should be: WS_VISIBLE | WS_CHILD.i get this error: Error: undefined identifier capCreateCaptureWindow
You need a header module that imports the function. Try the vfw.d module at the project Jarrett pointed you to.my compile comman is: dmd webcam.d gdi32.lib advapi32.lib
You'll also need vfw32.lib, which isn't part of the DMD distribution, but will be on your system if you've downloaded the Platform SDK - in which case, you'll need to run it through coffimplib (ftp://ftp.digitalmars.com/coffimplib.zip).what am i doing wrong? how can i acces my web cam?

Hi John, I also downloaded the said win32 zip but don't know how to compile to lib or dll,doesn't need to compile? or how to compile? Thanks. Regards, Sam

Huh? You just run coffimplib -f vfw32.lib and specify the .lib on your build command line - something like: dmd webcam vfw32.lib

Those are warnings, not errors. Ignore them, it will compile anyway.

Ah ..yes.It work .BTW,just cfw32.lib is needed,no need gdi32.lib to compile. Thank you so much! Regards, Sam
