Re: [Boost-users] [Boost][Bind] How to bind template function member

Thanks a lot... and I'm sorry to have not seen the args mismatch in your
first mail.

With this explicit cast, the bind function compiles. 

Thanks for your help.

Oops, I read you example more clearly now. The arg types don't match, it 
should be a cast to (void (X::*)(int&,int&)).

I'm not sure where the restriction is, just that it works. I think VC8 
handles the specialization syntax correctly. Be gald you are only 
getting a compile error. I tried doing something slightly more 
complicated recently and got an ICE with VC71, but not with VC8. Doing 
the cast gives the compiler the context it needs to decide on which 
overload to use.
