c++ - Unhandled Exceptions from Managed C# User Control used in MFC Dialog -

-

Our main application is built in MFC C ++, but we are trying to write new code in .NET , And a user has been created will be used on existing MFC dialogue.

However, when an unexpected / uncontrolled exception is removed from user control, it crashes the MFC app (illegal session style), there is no merit to recover.

I have added 

  AppDomain currentDomain = AppDomain.CurrentDomain; CurrentDomain.UnhandledException + = new unrestricted expansion event handler (currentDomain_UnhandledException); Application.ThreadException + = New ThreadExpress Event Handler (Application_ThreadException);

For NET user control creator, but it seems to catch nothing.

Is there any way to add an event to the MFC to handle them?

Quick Google does not return anything useful

Thank you.

Edit: Even then the way I want it is not able to solve it, the way to do it is the best , all the NIT codes, So there is no exception bubble.

I asked this same question some time ago:

What I've got This is that the managed unwanted exception event only operates on a managed thread, the fire only operates in WndProc, where the magic happens.

You have a few options: You can put low-level overrides in CWinApp and hold exceptions. It can be an unexpected side effect or you can go with Structured Exception Handling (SEH) which will give you a hack on all / uncontrolled exceptions. This is not an easy road.

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...
