Hi all,
I am newbie to Boost library. I am trying to use multi_index_container
library in my project. The problem I have at my hands needs One Hash
index and one ordered indexed. I refer the Boost tutorial and Advance
topic and tried to write the following snippet. But when I compiled it
gives compilation error. I searched lot of different options and tried
to fix it but I could not able to do it so.
If you can guide me how to shut the compilation errors it will be great.
If anyone of you is having any decent example tried out for Hash having
ordered indexes please send it to me so I can go through and build my
logic on top of that....
Code Follows.
I am using MSVC SP6 on Win XP .
