workflow foundation - Update EntityKey Reference in Entity Framework -

-

I have created an application using asp.net, the Entity Framework and the Windows Workflow Foundation, and hopefully everything works

My ASP.Net page should start the workflow that executes and updates a unit passed from the workflow to the page. Everything works well: I use the work pattern unit to share the reference between asp.net and WWF and my unit is updated successfully during the workflow ... except for a single unit which That my unit has been prepared as a reference to another entity.

Let's assume this case. The main unit is called the item in which the situation is called, which is a foreign key for another entity called status. When I make an item, I make it with the usual syntax like 

  item i = new item ();

Then I create the context of the position unit in this way: 

  i.StatusReference.EntityKey = New system. Data Antiquity ("myEntities.StatusSet", "Idestatus", state);

Where hardcounted is an integer value in the state workflow phase.

Every time I try to update this unit (item one) I follow these steps: a) I created the property (a new, created as the unit of operation for the following transaction GET) I get the unit from:

item item.idItem == itemID selection item from item i = (ctx.ItemsSet). FirstOrDefault ();

The unit is then attached to my reference EntityState is unknown

b) I update the status reference as before: 

  i Status Reference. Antitiki = New system Data Antiquity ("myEntities.StatusSet", "Idestatus", state);

c) I save changes in references like: ctx.SaveChanges ();

By using the vs2008 debugger, I can see the update unit and when the changes are saved I change all properties (revised date, item name and other startups), but the unit reference is still the original issue Gives points on

Can someone give me some help ?!

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...
