filesystems - iPhone - fopen and pathForResource - Permission denied -

-

I tried to open a file directly to fopen ("/ test.txt", "w +") Is ; It works on the simulator but does not work on the iPhone.

Then I have tried this: 

  NSString * path = [[NSBundle mainBundle] pathForResource: @ "GirlName.txt" type: zero]; NSLog (path); Feature = Fopen ([Path SistringUzching Encoding: 1], "W +"); If (fichier! = NULL) {...} else {perror ("error"); }

I get permission in the console: 

  2009-07-24 17:17 17: 27.415 Madomocell [8 9 7: 20b] / var / Mobile / application / ... / .... ap / golnam Commentary error: denied by permission

Can you tell me what is wrong?

You can not open a file within the application bundle and write it ("w +") Can create.

This same code will probably work (if you have changed "R" mode then

If you need a writable text file, you can write one In the qualified directory, I will do something like this: 

  // method writes a string in a text file - (zero) writeToTextFile {// Get the directory of the document: NSArray * path = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES); NSString * Document Directory = [Path ItemOutIndex: 0]; // Write a file name to write the data to use the document directory: NSString * fileName = [NSString stringWithFormat: @ "% @ / textfile.txt", document directory]; NSString * content = @ "test Copy here to save the content to the document directory [content content file: filename atom: no encoding: NSStringEncodingConversionAllowLossy error: zero];}

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...
