c# - WPF: Passing objects between UI Thread and Background thread -

-

After InitializeComponents in my window creator, I can create an object and bind it to a datagrid needed. Since the creation of the object is taking a lot of time, it takes some time to show the window. So I decided to move the creation of the object into a background thread and gave the UI thread "back rep" by binding a dispatcher to bind. But it fails

The strange thing is that if I try to set the visibility of a rectangle within the DispatcherWhok, which works but the datagrid does not! any idea? I've tried the same thing with background workers and ThreadStart, but I'm getting the same error. I'm not able to access the Data Grid Object, it is still going inside the Dispatcher, inviting the delegate. There is a lot of gratitude for any suggestion that I am missing something in my understanding of how it works. Thanks! 

  startupdevelopets = new startupdelegate (create modal); S.BeginInvoke (Representative (IAsyncResult aysncResult) {s.EndInvoke (aysncResult);}, tap); Internal MacDel () {model D = new model (); Dispatcher.Invoke (DispatcherPriority.Normal,  (Representative (model d1) of the new action {mModel = d1; // mModel is defined in a property window binding = new binding (); b. Source = mModel; MainDataGrid.SetBinding (TreeView.ItemsSourceProperty, mainb); // with & lt; here dies - because a separate thread it owns the owner calling thread can not use this object}}

Update <. / Strong>: ... a dispatchertimer that will be able to run just once get binding code in its tick representative But I'm still curious why does not the code above

I have another way

Binding should not be called by the code, instead you should define it in XAML.

You add a more DependencyProperty to the type model on your window and call it " CurrentModel "and can set your initial value to zero. Area only to find a property called mModel that DependencyProperty?

You can define the current grid of the current grid or the control in which XAML.

And in its end of the representative, Dispatcher.Invoke should set the current MODEL only, the binding will be done automatically.

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...
