Yes, I want it. I want to this interface become a system level service 
-- such as provide a method as NS_GetStringService(), and can call this 
method before NS_InitXPCOM2().

In this way, there is no need for me to implement nsAString and 
nsACString. As "string" and "wstring" have well defined binary format, I 
can always create "string" and "wstring", then use nsIStringService to 
convert from/to nsAString and nsACString.

As I haven't touched C/C++ for a long time, so I try to use C/C++ as 
little as possible. Also, I expect XPCOM more like a binary protocol, 
same as COM/OLE, do not limit on the language that implement it. That 
is, for any language that provide language level or API level ability to 
manage the binary layout of things, should be able to use XPCOM. To my 
case, swt provided a set of native APIs that enable me to manipulate 
memory, so I can construct/convert memory block conform to the 
"string"/"wstring" format. Also, I can call XPCOM objects using the vtbl 
format. Further more, swt also provide mechanism to receive vtbl 
incomming calls and map to java method, this will enable me to write COM 
object implementation in Java code. The three things enable swt to 
manipuate COM/OLE, I think this three thing should also enable me to 
manipuate XPCOM.

Unfortunately, after I be able to list all the registered components 
(this only require me to use "string", no need for nsACString"), I don't 
know how could I manipulate "nsACString".

If I can get nsIStringService, then I can work around nsAString.

So far, seemed I must write more C/C++ code and write my own nsAString 
implementation. The hardest thing then is how to set up the environment. 
Do I need to download all the mozilla source code and get it compiled? 
Or there is a set of lib file and .h file that I can download and 
include in my C++ project? Is there any sample or document how to set up 
a VC6.0 project for this?
