Intellisense and auto-complete in VC6 has many problems with advanced
features like templates.  There's normally nothing you can do.

This is a limitation of how VC++ compiles C++ code, and to some extent, a
limitation of C++ itself.  Template definitions are only barely parsed by
VC++ when they're encountered and aren't subject to a complete syntax check
until they're instantiated.  In general, it's not possible for a C++
compiler to determine if a template is valid until it's instantiated (since
the validity of the template depends on the type(s) used in the
instantiation), but VC++ could catch more errors than it does.

The solution to this is to properly test your software - write a test suite
for your template that exercises every member and feature.  You do that for
all your code, right?
