I will also look into Boost libraries once I have a bit more confidence in STL itself.

I wanted to write a browser plugin. In Firefox, I could simply write some javascript with XUL to get things to work. In Internet Explorer, from my online searching, it seems that I have to write ATL code if I want a toolbar with buttons (Explorer Band)?

Now writing Javascript for one and ATL for other seems like a lot of repeatation. I would like to use Javascript for both. Is it possible to simply write a toolbar in ATL and call some javascript code for the toolbar buttons to manipulate window elements? If so, how can I call the Javascript from ATL?

I think that method insert is not very efficient (am I right?);
what if I use copy in ?

std::vector<t> vec1;<br />
std::vector<t> vec2;<br />
<br />
std::copy(vec1.begin(), vec1.end(), std::back_inserter(vec2));</t></t>

please help...
Thanks,
