I would like to write visualizers for native C++ code.
Is there a way (simple or complex) to have more control (ex: custom
containers, reference to lookup tables...) over the watch window than with
the autoexp.dat file?

Thanks!

Have you taken a look at the EEAddIn sample?

You can build an external DLL and hook it up in autoExp.dat via the $ADDIN()
tag. I think all that built-in native VC++ visualizers do are contained in
autoExp.dat (whether it is sent out to external DLLs or not).

Yeah, I already use that in some instances. The main problem is that it only
returns a string. I didn't find a way to add children items (like std::vector
for instance) with this method. The visualizer section of the autoexp.dat is
almost what I need if I could do just about the same in an external dll.
