do_GetService.

[abhilash maniam]

Hi,

I am using Microsoft Visual Studio .NET and have this line in my code

nsCOMPtr<nsIWebProgress>
                progress(do_GetService(kDocLoaderServiceCID,&rv));
The compiler says do_GetService is an undeclared identifier. I have 
"nsCOMPtr.h" in my include list. What other files should I include?

Also,
I try to replace the above line with this:
   nsCOMPtr<nsIWebProgress> progress;
   rv = servMan->GetService(kDocLoaderServiceCID, 							 
NS_GET_IID(nsIDocumentLoader),
					getter_AddRefs(progress));
and this..
   nsCOMPtr<nsIWebProgress>   							 
progress(do_GetService(kDocLoaderServiceCID,&rv));
   if (progress)
	 progress->AddProgressListener(this, 										 
nsIWebProgress::NOTIFY_STATUS);

But my program crashes on exiting the function where this code is there. 
Is there anything wrong that I am doing with GetService.

Thank you.
