I check the mailing list, and find there are some old mails discussing the same problem I encounter.

 http://www.wireshark.org/lists/wireshark-dev/200612/msg00005.html

The wiki tips page has a couple of useful sections on debugging and setting up browse info for MSVC.http://wiki.wireshark.org/Development/Tips

I've also done it by creating a dummy static library project and using Wireshark as the "program" under the debug settings (useful for putting a breakpoint in start-up code).

 Done all the wiki recommendations. I can now single/step debug main.c,

but as you can imagine, my interest lies deep in one of the dissectors - e.g. packet-h263.c etc. How to I get to the situation I can single step through those?

May be these mails can solve my problem. 

But I don't know how to "creating a dummy static library project and using Wireshark as the "program" under the debug settings"....

Hope you could help me, thanks....
