when i try build my program i get this error:
fatal error C1075: end of file found before the left brace '{'

i know it means i'm missing a bracket somewhere but there is only 6 brackets in the program and there are all there. if i click the error it just brings me to end of the program and if i add an extra bracket it gives another error

Check your "ContextExample_h.h" file. Error might be there.

there's no error in the header file

check the macro - RpcTryExcept. this is just a starting brace

//rpc.h
#define RpcTryExcept \
    __try \
        {




you need to end this by its closing brace. look for examples on how to use it.

there's nothing wrong with that file either...

All RpcTryExcept statements must be terminated by the RpcEndExcept statement.

Your problem

Or you can look into how this unnesesary macro is defined and try to balance braces...
Or alternatively use standard ways to handle exceptions

Yea miinipaa's right.
If i put another closing brace at the bottom of your cpp file the error changes to:
Error: expected __except or __finally

does the code not do this?

just comment out your 'RpcTryExcept{'

just comment out your 'RpcTryExcept{'

in the code in the first post?

yup.
lines 70.71 and 90.

those are the # defines. your code is actually doing this:
