.net - ADO.net Entity Framework: Update only certian properties on a detached entity -

-

I want to update a unit without loading unit from the first database.

I completed it, but only after knowing the properties of all entities and then using "Atato" method.

My problem is that I do not want to remember all the properties of my app. Example: 

  new shopper as dim customerEntitiy customerEntitiy.shopper_id = CustomerData.CustomerID customerEntitiy.market_code = CustomerData.MarketSector customerEntitiy.email = CustomerData.Email customerEntitiy.modified = DateTime.Now context.AttachTo (made "shopper", customerEntitiy) context.SaveChanges ()

unit area on the one that's why "". I do not want to pass this "created" date through my "n" level app. How do I "update" the area when saving the database? Thanks! Paul

I figure it out, basically, you instead use a stub, attach it , then set props you want to update the unit structure will update only changed things 

  dim customerEntitiy as new commerce_shopper customerEntitiy.shopper_id = CustomerData.CustomerID context.AttachTo ( " Commerce_shopper ", customerEntitiy) 'This primary key is' customerEntitiy.market_code = CustomerData.MarketSector customerEntitiy.email = CustomerData.Email customerEntitiy.modified = DateTime.Now context.SaveChanges ()

This" Built "date field ignore.

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...
