WPF Binding to property and setting another -

-

I am using MVVM in my WPF application.
I have a window in which there is a view inside it. The value can be changed in that view and I will tie it in a text box in my main window:

Now I will need to force this to myViewModel.MyValue for a property inside my main window view model, so that I can filter it into a You can use the collection.

Can I use a setter or something else that sets the value of MainViewModel.Property whenever myViewModel.MyValue Does change happen?
If so, how can I do this?

Does the visual model of your "all" scene reside in the "main" window viewodol? If so, then you can only trigger these things through the setters.

If not, you can use the ancestors binding and run it from the UI. It is not ideal (I thought that you are trying to avoid the thoughts of parents and children from each other's specific knowledge), but this will work.

Here is a RelativeSample sample which is very easy. These can be quite complex. Experiment with caution:

If you decide to go do the reluctance route, then you should know how to debug the binding Use it for many Techniques, but if you are using .NET 3.5, then I recommend using that method (near the end of the article).

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...
