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

[Darin Fisher]

I forgot to mention one detail.  nsIHttpProtocolHandler is not a frozen 
interface, so you cannot rely on this interface existing in all future 
versions of mozilla.

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.

Thank you for this replay. This is realy bad news for me.
Maybe is a way to get UserAgent string using XPCOM without creating 
browsers
instance?:((

Best regards, Dmitriy

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?

I found the XPCOMFunctions struct which are having version field but

        

most

    

likely can't use it.

Any ideas ?
