oop - What exactly is the model in MVC -

-

I'm a bit confused about the model is quite limited. I think it works with data from the database and so on. Can it be used for something else? Take for example a certification system that sends an activation email to a user when they register. Where is the most appropriate place to place the code for the email? Is a model suitable ... or can it be kept in better view, controller, etc.?

The model is how you represent the data of the application. This is the state of the application, the data that will affect the editing of the application (view: visual presentation), and the variables that can be tweaked by the controller.

To answer your question specifically

The content of the email, the person sending the email, is the model.

This code that sends email (and verifies email / registration verifies first place) and email content is set in the controller. The administrator can also generate email content - you probably have an email template in the model, and the controller can replace the placeholder with the correct values ​​from its processing.

Basically the "Authentication email has been sent to your account" or "Your email address is not valid" so the controller looks at the model and determines the output for the view.

-
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...
