asp.net mvc - Linq to SQL Entity Splitting -

-

I have recently started playing with the ASP .NET MVC NerdDinner sample, and as part of it you It can look good with Linq from SQL class, so I tried to remove (probably a boy before time!) And tried to create my own MVC application, but this time Linq to SQL Modeling your own simple database with.

This is going to be

  • Traveler
  • Traveler

    • Table Carpooler

  • There is a mapping table between Em> car and person (it has two columns: CarId, PersonId).

    In SQL, in SQL, I get a square for each table. But, what I really want is a class for the car , whose property is carpasizer , with each child person , the actual FK Rather (to select the result is OK, but to update the car with the new person objects, I have to first build them - I can only add an entity set of carpasors without installation of only the person's person objects) .

    I'm looking around and I have seen that the ADO The Net Entitie Framework will allow me to use unit splitting to get it, but I'm surprised Linq to SQL is an easy way to complete the same thing, and if not, with my MVC App NAT EF What is affected in the case of integrating

    Any advice, comments, tips will be greatly appreciated.

    Thank you!

    • If you define FK before adding them to the surface of the designer, What would you expect to be closer to the way carpasengers will exist but this would be an entity set of carpasenger objects, not the person. Those items, however, will be will EntityRef is an affiliate, this will allow you to find passengers in the car. 

      var car = db.Car.Where (c => c.CarId == ID); Var passengers = db.Car.CarPassengers.Select (cp = & gt; cp.Person);

    Adding new travelers also works, but there is another step in it too. 

      var car = db.Car.Where (c => c.CarId == ID); Var person = new person {...}; car. Carpager. Add (new carzager {person = person});

    If you do not have a timely defined FK relationship, you can always add affiliate to the designer manually. MSDN is on this topic.

    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...
