c# - How can you determine whether a form has been closed by the user or by your code? -

-

I have a form (let's call it as parent), of which "always not on top but rather modal "The form can be filled (like a dialogue, but a dialogue - the user can leave the new" child form "where he is and continues to work as a parent).

When the user opens for the first time, some data is loaded and displayed to the child. Do they close the form, I actually block the lock and just hide the form - so that they can open it next time, we do not need to reload the data (this is not the data that changes at all is). 

  if (e.CloseReason == CloseReason.UserClosing) {E.Canel = true; This.Hide (); }

Later, when the parent's form closes, I want to force the child to close the form properly - next time its location and size is stored To do this, it has to run some base code. / P>

Currently I call childForm.Dispose () from the nature of the parent who cleans the thing well, but does not give me more control.

However, if I call the child. Close () method, e. Closerson is still "CloseReason.UserClosing".

Is there a way to differentiate between the user form and closing my code (basically) shutting it down?

Just a special " in fact close () And it is said that when you really want to close the form.

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...
