Relational UML Diagram inspired by SO -

-

My homework was to create a relational UML diagram about a discussion site. I used, and I made some amendments:

  • Age deleted in user information
  • Added delegates, who posted users by their user name (voluntary)

Otherwise, the schema is similar, but it is rudimentary how will you improve it?

Explanation

The main idea of ​​delegates is to categorize the post. Only a handful of names in the list are in contrast to the badge, the idea is not strange, but organized is. If you ask questions about mathematics, then you can be Steve.math or just math . This helps other users to look just like you, and you are not wasted space for the username . Perhaps, there is an easy way to organize things, so do not hesitate to comment.

vote

Users

  • To get rid of 

      Upwits and downwots, which is information that can come from the vote table.  
  •  Make it an 'integer' unless you have a really big site, then no GUID is required as a user ID.   
     must have an ID  GUID    
         If you have  delegation , then I will change its name 
     
       
    •  P> Otherwise, I do not think there is a good idea to keep it - something that ' tag ' can tell you, unless I fully remember why it exists .

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...
