php - OOP design approach for two interacting classes -

-

Relative advantages / disadvantages by using classes (or rather; Are compared to nesting classes?

I am trying to reconstitute my user / authentication system and I am surprised;

  • MyAuthClass should act as a utility and if log-in is successful, just create a new myUserClass object
  • or myAuthClass should internally create myUserClass ( I.e. $ the-> user = new myUserClass)
  • Or even if myUserClass should only call myAuthClass when needed (i.e. when a user tries to log in) and its Updates internal structure (new email, favorites, cart, etc.) as needed.

As you can tell that I am able to make a case for each method of appropriately of an OOP N & SB, so I'm about the different ways + I am interested in hearing from others.

Cheers. <3 p>

With an extraordinary perspective, all 3 options are incorrect because they are programmed against solid implementation And not an abstract interface. As they gather together in a joint together, who reuse the reusable limit - whether you use both of them again or not.

You can generate IUserClass, or IAuthClass and apply this abstract interface in a solid range, and then I

allow most flexability in each case In the situation where an IUserClass, or user class was given the implementation of IAuthClass while authenticating to populate the implementation of the auth class. The Auth class can be reused and different versions of UserClass can be generated, or the user has the ability to use many different authentication mechanisms in the class, as long as the heir to IAuthClass.

User class A certification object (which implements IAuthClass) will be my preference, that authentication mechanism varies, even with the same application, when the user class will be reduced but true To be, no solid implementation should be based on.

It can be seen from above, so this is a decision call.

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...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. 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. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the 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...
