iphone - A/Synchronous NSURLConnection: get response without download data? -

-

Help is highly appreciated I'm stuck here:

Loading URLs in my UIWebView I need to check a response before starting. However, a synchronous NSRR connection will first download the data and then I should use the feedback, which is bad.

An asynchronous NSURLConnection will allow me to examine the reaction before receiving any data, but I can only examine the response in the delegate method connection: did the reception. But then I will have to wait for my webview's delicate method (webview: needstartLoadWithRequest: Navigation Type :) until the response is no. Because both the representatives are in the main thread (should they be? I feel like this) I can not use the NScandition only to stop the webview representative (means to stop the main thread).

Anyone have an idea how to solve this problem?

Thanks in advance.

If you just need headers, then you should first request a head (rather than a GET ) It will only return the headers without any body. It can also be fast enough that you can consider syncing it, although you obviously want to test it completely.

Update
Basically, do not do this synchronous. Even with the size of a small reaction, you can be as much as possible by delaying the request alone.

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...

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.

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...
