Probably the CHideAndSeek() class should help?
Seriously though, what is your requirement?

Actual i have to design a dialog similarly as the equavalizer window that comes in winamp,(whenever we press a arrow it opens and whenever we press a arrow again it hides)...

Will the ShowWindow() API help you?

Use a combination of SetWindowPos and/or MoveWindow to grow/shrink said window; thus show or hiding a portion of the dialog.

Will the compiler optimize the MESSAGE MAP of each class?
Or else, I'd better rearrange it by putting high-frequent messages at top of the array.

How could the compiler know which messages occur with more frequency?

I guess he supposes the compiler optimizing message handling on position (in the MESSAGE_MAP list) based mechanism, this way the developer could suggest the compiler itself what will be the more frequently used message.

It's in the service pack, Mark. Come on, you're gonna have to keep up.

Exactly. You can lead a compiler to water but you can't make it fish.

Are you sure? That may be in the service pack as well!

Yeah, it makes me picture that scene in Jaws where all the bounty hunters are flying around the marina in boats with shotguns and TNT etc.

some can be determined, like
WM_PAINT vs WM_CREATE

By the compiler?
I don't know of any MFC/Windows-specific optimizations in the VC++ compiler.
The source code for the BEGIN_MESSAGE_MAP macro will tell you if
it's optimal to move frequent messages to the top.
FWIW, I've always done that, but I've never bothered to check if it helps.
For all I know, it's the reverse Please let me know what you find!

Do you have any metrics to claim that the MESSAGE_MAP is not optimal ?
anyway, if that's your only performance concern in your application, you can just stop there and go have a beer.
|
|
|
|
|
Why not put WM_PAINT before WM_CREATE?
Maybe the perform here can be ignored.
|
|
|
|

If the MESSAGE MAP really IS a map, then the order of items is not likely to make a difference at all...
Peace!

Do you experience any problem with your application ? Is it so painfully slow that you need to look at each msec that you can gain ?
Otherwise, I'll cite a famous quote from Donald Knuth:
Early optimization is the root of all evil.
With which, on this specific case, I absolutely agree. You'll probably end up doing things much worse (making the code more difficult to maintain, full of bugs, ...) just to gain something totally neglectable.
