What's faster/better to use: the MySQL or PHP md5 function? -

-

I have checked the password for users against DB.

What is faster, MySQL MD5 function 

  ... pwd = MD5 ('. $ Pwd.')  < / Pre> 
 or  PHP  MD5 function 
 
  ... pwd = '.md5 ($ pwd).'  
 
 What is the correct way between the two options?

If your application is only reducing MD5, when someone registers your site, Or entering, you can do many calls on MD5 itself? Couple of hundreds? If so, then I do not think that really small difference between PHP and MySQL will be important at all.

The question should be more "Where do I say that the password is stored in comparison to" MD5 "compared to" winning almost nothing. "

And, one In the form of sidenote, another question may be: Where can you spend to spend resources to calculate that kind? If you have 10 PHP server and a DB server which is already heavy load , Then you get your answer; -)

But, for fun A: 

  mysql> Select benchmark (1000000, MD5 ('test')); + ------------------- -------------- + | Benchmark (1000000, MD5 ('test')) | + -------------------- ------------- + | 0 | + -------------------------------- - + 1 line set (2.24 seconds)

and in PHP: 

  $ first = microtom (true); for ($ i = 0; $ I & lt; 1000000; $ i ++) {$ a = MD5 ('test');} $ = after microtom (true); echo ($ later- $ first) "\ n";

returns: 

  $ php ~ / developpement / tests / temp / temp.php 3.3341760635376

but you might Like a million MD5 Will not count, do you?

(And there is nothing to stop it from stopping the SQL injection: Just avoid / quote your data! Always! Or use ready statement)

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
