  • UIWebView comparing current and defined URL's with a loop depending on result

    - by Syleron
    I am trying to compare the current url in webView with a defined url say google.com so in theory.. NSURLRequest *currentRequest = [webView request]; NSURL *currentURL = [currentRequest URL]; would give us our current url... NSString *newurl = @"http://www.google.com"; this would give us the compared to defined url while (!currentURL == newurl) { //do whatever here because currentURL does not equal the newurl } This does not seem to work though.. solutions?

  • Wordpress installed in root folder, subdomain now not working, GoDaddy host

    - by Kristin
    Hi, please forgive me for being a complete beginner at this, I'd rather not have to try to deal with this myself but as GoDaddy support have not replied after 2 days I'm going to have to. I think my problem is the same as the one above, but I'm not 100% sure, so I'm reposting it, I'm not really confident enough to attempt to try the fixes I've seen here so I need someone to give me baby instructions? Our original website (www.mwpics.com.au) was built in Dreamweaver etc, recently we created a new website in Wordpress, in a subdomain, then migrated it over to the root folder where it is now operating fine. I also moved the files for the old website into another directory which I called 'old', so they're all still there. The problem is that I have a subdomain set up - which is still showing as set up in the control panel on godaddy the url is www.mwpics.com.au/clients and it is at www.clients.mwpics.com.au. This directory contains loads of other directories, each of which is password protected by .htaccess files and which our clients access directly (not through the site) to download their finished work. The test one and the one for random clients is www.mwpics.com.au/clients/temp - username and password both temp (the usernames are all the same as the directory names). Since the WP install to the root directory the /clients extension no longer works (it should bring up an information page which is an .html index page in the directory) and the /clients/name extensions no longer works - it goes back to the wp site with a 'not found' error message. Strangely it does bring up the box for the username and password, but when you enter it it just goes back to the 'not found' message. Someone told me it was the .htaccess file - so as an experiment, I renamed the .htaccess file in the root directory and then copied the .htaccess file from the old root files into the root directory, eureka! It worked - and also the WP site opened to the home page... but bummer - the /pages in the WP site now no longer worked! But at least I know the source of the problem. So I switched it back and this is the status quo - I have no idea how to fix this, and with everyone back at work tomorrow, clients are going to want to start downloading their stuff... Can anyone help me? I'm starting to panic a bit

  • Problems Installing Eclipse and Ruby Plugin

    - by Jesse J
    I installed Eclipse on my Ubuntu machine and then the Ruby Development Tools (RDT), but it would crash when I try to alter certain features, like having line numbers, how far back to have history, and the code coloring scheme didn't work fully. I decided to try to uninstall Eclipse by doing sudo aptitude remove Eclipse and then sudo aptitude install eclipse but instead it installed it back with the broken Ruby plugin. I also tried aptitude purge but that didn't help either. How can I freshly reinstall Eclipse and get a properly working Ruby plugin?

  • Does SQL Server have any kind of magic undo feature?

    - by Andrew G. Johnson
    Long story short is I tried to quickly update a single row in SQL Server using the Management studio and just typed UPDATE table SET column='value' and forgot the WHERE other_column='other_value' portion. Went for lunch, came back and theres 15 unread emails waiting for me. Happened about an hour ago, waiting for the database guy to come back to see when the last backup was. There's no magic UNDO feature though is there?
