Re: How i can get the XPCOM version using C++ ?

Hmm... you could try using nsIHttpProtocolHandler to read the UA string. I suspect this requires the layout component to be initialized (since it configures the product portion of the UA string), but that's probably reasonable assuming you would do that anyways if the UA checked out.

Try this:

   nsCOMPtr<nsIServiceManager> serviceMgr;
   rv = NS_GetServiceManager(getter_AddRefs(serviceMgr));
   if (NS_FAILED(rv))
     return rv;

   nsCOMPtr<nsIHttpProtocolHandler> httpHandler;
   rv = serviceMgr->getServiceByContractID(
           "@mozilla.org/network/protocol;1?name=http",
           NS_GET_IID(nsIHttpProtocolHandler),
           getter_AddRefs(httpHandler));
   if (NS_FAILED(rv))
     return rv;

   nsEmbedCString ua;
   rv = httpHandler->GetUserAgent(ua);
   if (NS_FAILED(rv))
     return rv;

You could also query the "misc" member to access the "rv:1.6" portion of the UA directly:

   nsEmbedCString misc;
   rv = httpHandler->GetMisc(misc);
   if (NS_FAILED(rv))
     return rv;

It really is a shame that you can't easily query this information. I think we should really export a version check function from xpcom. That would be easy to implement since we have a MOZILLA_VERSION #define.

Maybe is a way to get UserAgent string using XPCOM without creating browsers
instance?:((

PS. Sorry for my English.

There isn't a good API for this (that i'm aware of) unfortunately.
However, on each system that has a GRE installed, there are platform
specific ways to determine the version of the GRE installed.  There's
good info on how to do this on the WIN32 platform here:
http://www.mozilla.org/projects/embedding/GRE.html
I hope that helps,

There isn't an explict way to do what you are asking.  I guess you can
try to use the version in the XPCOMFunctions, but I am not sure that is
going to get you what you want.
What are you trying to do?

Any ideas ?
