I run the HIDClient project in VS2008 Pro Edition but it didn't build successfully the error message:fatal error C1083: Cannot open include file: 'afxwin.h': No such file or directory. I searched everywhere and do a steps for some configuration and build the solution but still I got the same error. I also follow the steps for building the application in this discussion http://www.keil.com/forum/12727/hid-client-example/ but still the same error i've encountered. Anyone knows how to figure out this error? Please share it to me. Thanks.
