php - Question regarding MVC: SubClass for DB activity -

-

I just recently had OOP & amp; Now using MVC and this template engine:

Where have I placed my DB calls, but I'm curious about a question (I'm using a basic database wrapper class).

We have seen two ways.

Category Cart 

  / ** * Item count in cart * @ Layer intern / Public counting counting function () {require_once (DATABASE. 'Cartext.php' ); $ Info = User :: getInfo (); $ Count = CartExt :: inCart ($ info ['0'] ['userid']); Return $ count; }

Then in the class cart 

  / ** * User cart count * @ Ultimate intra * return int * / public static function inCart ($ shopperID) {$ Db = Database :: getInstance (); $ Query = $ db- & gt; Execute ("Selection from Listing" where shopperid = '$ shopperID' "); $ Count = 0; While ($ line = $ db--gt; get all ($ query)) {$ count ++; } Return $ count; }

With big functions, I can see the benefit of separating two, but as a later example, it is very similar to brain, or worse: Base Class Just calls ext. And returns its value!

Anyway, I just want some ideas on this.

In addition, I am doing a correct_once function to reduce the http requests from

In addition, I am right that I have $ $ _POST in the controller '] Should handle it and pass it as an absolute thing to my actions, should it be opposed to handle in the classroom? (I'm not using any Form Object / Class yet)

Want to hear your thoughts on this.

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...

I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image.

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...
