  • Object-C: initWithContentsOfURL returning null

    - by AragornSG
    Hey! I'm working on an app that would display a remote html and use local images, so what I'm trying to do is download the HTML of the website and display it as a "local" page, that would have access to images in my bundle. For some reason I can't get initWithContentsOfURL to work. I checked all manuals and examples I could find and it seems that I'm doing it correctly, but the thing just won't work, returns null all the time. The same page loaded with NSURLRequest requestWithURL works fine. Appreciate your help! Here is the code: - (void)awakeFromNib { appURL = @"http://dragontest.fantasy-fan.org"; notConnectedHTML = @"Could not connect."; NSString *seedString = [[NSString alloc] initWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@/seed.php", appURL]]]; NSString *HTMLdata = @""; if (seedString = @"(null)") { NSLog(@"Can't connect on awakeFromNib."); HTMLdata = notConnectedHTML; }else { HTMLdata = [NSString stringWithFormat:@"<body style='padding:0px;margin:0px;'>%@%@</body>", seedString, @"<br><img src='images/Default.png'>"]; } [homeView loadHTMLString:HTMLdata baseURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] resourcePath]]]; }

  • Change date format (in DB or output) to dd/mm/yyyy - PHP MySQL

    - by Jess
    MySQL stores the date in my database (by default) as 'YYYY-MM-DD' The field type for my date is 'DATE' (I do not need any time storage).. Is there a simple way to change it by default to DD/MM/YYYY ? I call up different dates in 2 different tables, and no where in any of my code do I have anything resembling a date variable or anything! Hopefully this is a straight forward change?

  • Android Assets No Value Read?

    - by BahaiResearch.com
    AssetManager assets = myContext.getAssets(); String[] files = assets.list("MyFolder"); InputStream myInput = assets.open("MyFolder/" + files[0]); int i = myInput.read(); in this case 'i' is -1 meaning nothing read. Why would nothing be there if the file is there, the variable 'files' has the file as well. Do I need to do anything to the file I put into the Assets folder in get it to be readable?

  • ldd output showing shared object file whose function is not called

    - by iamrohitbanga
    I ran ldd command on an executable created by Open MPI. It shows a reference to libpthread.so Using LD_PRELOAD variable I created my own implementation of pthread_create, but from the it output it seems that MPI implementation is not calling pthread_create as I had expected. Why does ldd show pthread so file in output if it is not being used? does Open MPI not use a separate MPI thread for every node to implement the functionality?

  • Give the mount point of a path

    - by Charles Stewart
    The following, very non-robust shell code will give the mount point of $path: (for i in $(df|cut -c 63-99); do case $path in $i*) echo $i;; esac; done) | tail -n 1 Is there a better way to do this? Postscript This script is really awful, but has the redeeming quality that it Works On My Systems. Note that several mount points may be prefixes of $path. Examples On a Linux system: cas@txtproof:~$ path=/sys/block/hda1 cas@txtproof:~$ for i in $(df -a|cut -c 57-99); do case $path in $i*) echo $i;; esac; done| tail -1 /sys On a Mac osx system cas local$ path=/dev/fd/0 cas local$ for i in $(df -a|cut -c 63-99); do case $path in $i*) echo $i;; esac; done| tail -1 /dev Note the need to vary cut's parameters, because of the way df's output differs: indeed, awk is better. Answer It looks like munging tabular output is the only way within the shell, but df /dev/fd/impossible | tail -1 | awk '{ print $NF}' is a big improvement on what I had. Note two differences in semantics: firstly, df $path insists that $path names an existing file, the script I had above doesn't care; secondly, there are no worries about dereferncing symlinks. It's not difficult to write Python code to do the job.

  • Read -> change -> save. Thread safe.

    - by Pavel Alexeev
    This code should automatically connect players when they enter a game. But the problem is when two users try to connect at the same time - in this case 2nd user can easily overwrite changes made by 1st user ('room_1' variable). How could I make it thread safe? def join(userId): users = memcache.get('room_1') users.append(userId) memcache.set('room_1', users) return users I'm using Google App Engine (python) and going to implement simple game-server for exchanging peers given by Adobe Stratus.

  • In Java, how do you parse through a single word string?

    - by Fraz
    I'm trying to parse though a string made up of a single word. How would you go about assigning the last letter of the word to a variable? I was thinking of using the Scanner class to parse the word and make each letter an element in an array but it seems Scanner.next() only goes through whole words and not the individual letters. Any help?
