com - Hooking thread exit -

-

Is there a way to hook the exit of managed threads (i.e. run some code on any thread,?) < / P>

I have developed the mechanism to extract the thread which works for the some thread Step 1: Develop a 'hook' STA com class which takes a callback function And it says in its destructor Step 2: Make a thread-static example of this object on the thread I want to hook, and convert the object to a unmanaged function pointer to a managed representative. The delegation then becomes a call on the exit of the thread (Since the CLR call IUnknown :: Release all STA Com RCW as part of the thread exhaust).

This mechanism works, for example the code using the thread class.

However, this does not seem to work for the main thread of the application (this is a console or window app) The 'hook' com object seems to have been removed very late in the shutdown process and the attempt to call the representative fails.

(I want to implement this feature so I can run some native com code, working on thread working with SATA com objects, which was created on the thread, before 'too late It is no longer possible to work with STA Com Objects (that is, it is no longer possible to get it done before thread is out).

Do you control the thread construction? It's possibly easier to wrap the code of the thread in a try ... end in the section, and finally put your code into it.

Note that when AppDomain stops, you can never make sure that your code is ever called "Dististor" when you call it C ++ / CLI Destistor - I.e. immersion method () method?

If you have to support hooking before exiting the process, you AppDomain.CurrentDomain.ProcessExit event - which is an unrestricted exception, or AppDomain.CurrentDomain. UnhandledException can not try to fire which only start to fire on an unrestricted exception.

None of these looks particularly strong, note you ...

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...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

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...
