Given #define TRACE_ID(iD) case iD: return L#iD;
Should
TRACE_ID(WM_INPUT) = WM_INPUT
or
TRACE_ID(WM_INPUT) = LWM_INPUT /* L at the begining */
what does "L" do here?
Thank you,

the macro should be L##iD.
## is a "token pasting operator".

HI,
In one of MS's samples, it uses one #. Actually this is documented in
Visual Studio help document.
Ok, even ## is right, why do we need "L" in the front? I have seen
L"string" for unicode. Have not seen L##X though.

#define TRACE_ID(iD) case iD: return L#iD;
TRACE_ID(WM_INPUT) gives your L"WM_INPUT"
# is called stringizing operator for preprocessor here
As for L macro:
In C, to make a string of wide characters, you need to prefix the string
with the letter "L".

Apparently, instead of getting an iD number, by which you have to look up
its meaning, you gets a meaningful string.
This is a very useful trick to getting meaning out of a #define number.

"I am happy you can understand me."
Is that Okay?

I'll add a few more:
"It was nice talking with/to you"
-"The pleasure is all mine."
-"Vice versa."
-"Nice talking with/to you, too."
You may also optionally add "Thank you" to precede your response.

not suitable for females
well, you may try and say it but i guess it will depend on to whom you're
speaking to.
if it was stud or newcastle don't do it
if it was netghost or friediceman i think it'd be alright

You've been staring at your monitor for too long.
Go outside, look at the sky, the mountains, take a break.
Reminds me of a DUMB joke from a cartoon.
Patient: "Doc, I think there is something wrong with my vision."
Optometrist: "Tell me what is wrong."
Patient: "Well, everywhere I look, I see these black lines."
Optometrist: "Let me take a look--is this better now?"
Patient: "Wow, Doc, what did you do? I can see clearly now!"
Optomitrist: "Let me give you the phone number of my barber..."
