core audio - How do I get the filesystem path for a resource on iPhone? -

-

On the iPhone, I need to get the path to the resource. I'm fine, it did, but when it comes to the CFURLCreateFromFileSystemRepresentation thing I do not know how to solve it. Why is this error? Any solution or solution will be highly appreciated. Thank you in advance.

To run audio using audioquake on iPhone, I have taken a look at the following examples: Speak Hear, Audio Options (from simple SDK directory) and AudioQuestate. I tried to do this and said that, trying to keep the puzzle together. Right now, I've been stuck on the program crashing up from the sndFile above the crash due to the exception.

On the actual iPhone device I am using AvAudioPlayer to play every sound on my iPhone games, the sound can be played when it is too short for the sound, so I decided that I AudioQueue must be used. 

  - (id) initWithFile: (NSString *) Argv {if (self = [super init]) {NSString * soundFilePath = [[NSBundle mainBundle] pathForResource: argv ofType: @ "MP3 "]; Int len ​​= [sound filepath length]; Char * fpath = new four [lane]; // This is to change the NSString * * To match / need the CFURLCreateFromFileSystemReresentation function (INTI = 0; I & lt; [SoundFileLength Length]; I ++) {FPIT [I] = [SoundFilePath CharacterEntx : I]; } CFURLRef sndFile = CFURLCreateFromFileSystemRepresentation (NULL, (const UInt8 *) trappath, strollon (trapped), false); If (! SndFile) {NSLog (@ "sndFile Error"); XThrowIfError (! SndFile, "File can not parse path"); }}

Why do you need a CFURL?

If you have a method that requires a CFL, then you can just use NSURL for toll free bridging. So to make NSURL, you just do: 

  NSString * soundFilePath = [[NSBundle main bundle] Pathfoser resource: argv ofType: @ "MP3"]; NSURL * soundURL = [NSUr File URL Thread: SoundFilePath];

In general, if you use CF objects, then you are probably doing something wrong.

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 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.

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...
