asp.net - Who's responsible for disposing HttpPostedFile.InputStream - and when? -

-

When you receive an uploaded file in asp.net, you usually do this HttpPostedFile objects. The received data is made available through the HttpPostedFile.InputStream . It is a property that has inspired me to believe that I do not have to settle myself, although in the documentation it has never been told who is responsible for discharging the stream, and if it is by ASP.net Framework, When does this (say, can I save the stream in the session, would I prefer?).

Now, I have not received this many files, and I have not run into problems to not dispose of this special stream, but for cleaning - does anyone know what the design contract is here is?

With my experience working with it, I will say that as soon as the request processing is complete, it will continue is done. One example is that I had to throw a ball in the air. If I will not catch it and it kills the ground ... it is settled if I catch it and do something with it ... and then leave it, it is settled. It does not drag you to play in the next request!

While addressing the issue of storage in the session, I would say Noo OO! If you have to keep it around for a while, then it must be written in the file system. When you need it, it must be reconnected as a stream and play with it. Storing a file stream in session (possibly as a byte array?) Seems like a heavy waste of your session (memory) resources.

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...
