• Simulate Click Javascript

  - by Belgin Fish

  Hi, I'm just wondering how I can have javascript simulate a click on a element. Currently I have <script type="text/javascript"> function simulateClick(control) { if (document.all) { control.click(); } else { var evObj = document.createEvent('MouseEvents'); evObj.initMouseEvent('click', true, true, window, 1, 12, 345, 7, 220, false, false, true, false, 0, null ); control.dispatchEvent(evObj); } } </script> <a href="http://www.google.com" id="mytest1">test 1</a><br> <script type="text/javascript"> simulateClick(document.getElementById('mytest1')); </script> But it's not working :( Any ideas?

• Translate This git_parse_function to zsh?

  - by yar

  I am using this function in Bash function parse_git_branch { git_status="$(git status 2> /dev/null)" pattern="^# On branch ([^${IFS}]*)" if [[ ! ${git_status}} =~ "working directory clean" ]]; then state="*" fi # add an else if or two here if you want to get more specific if [[ ${git_status} =~ ${pattern} ]]; then branch=${BASH_REMATCH[1]} echo "(${branch}${state})" fi } but I'm determined to use zsh. While I can use this perfectly as a shell script (even without a shebang) in my .zshrc the error is a parse error on this line if [[ ! ${git_status}}... What do I need to do to get it ready for zshell? Note: I realize the answer could be "go learn zsh syntax," but I was hoping for a quick hand with this if it's not too difficult.

• PHP form validation submit problem?

  - by TaG

  My code is suppose to save a year like 1999 to the mysql database but it wont. It will check to see if the user has entered only numbers and is at least 4 numbers long or if nothing has been entered correctly but it wont save the correct year? How can I fix this problem. Here is the PHP code. if(isset($_POST['year']) && intval($_POST['year']) && strlen($_POST['year']) == 4) { $year = mysqli_real_escape_string($mysqli, $purifier->purify(htmlentities(strip_tags($_POST['year'])))); } else if($_POST['year'] && strlen($_POST['year']) < 4) { echo '<p class="error">year is not correct!</p>'; } else if($_POST['year'] == NULL) { // do something }

• linq with Include and criteria

  - by JMarsch

  How would I translate this into LINQ? Say I have A parent table (Say, customers), and child (addresses). I want to return all of the Parents who have addresses in California, and just the california address. (but I want to do it in LINQ and get an object graph of Entity objects) Here's the old fashioned way: SELECT c.blah, a.blah FROM Customer c INNER JOIN Address a on c.CustomerId = a.CustomerId where a.State = 'CA' The problem I'm having with LINQ is that i need an object graph of concrete Entity types (and it can't be lazy loaded. Here's what I've tried so far: // this one doesn't filter the addresses -- I get the right customers, but I get all of their addresses, and not just the CA address object. from c in Customer.Include(c = c.Addresses) where c.Addresses.Any(a = a.State == "CA") select c // this one seems to work, but the Addresses collection on Customers is always null from c in Customer.Include(c = c.Addresses) from a in c.Addresses where a.State == "CA" select c; Any ideas?

• imageview draw issue with asynctask

  - by alexb

  Have the following asynctask that i'm using to download some images. Works fine except for the very first image, which doesn't always appears unless I do something like move to the next image and then back again. public class DownloadImageTask extends AsyncTask { static ImageView _imageView=null; public DownloadImageTask(ImageView ctl){ _imageView=ctl; } protected void onPostExecute(Bitmap result) { _imageView.setImageBitmap(result); } ... } I thought this might be an issue with updating the UI on a background thread, so I reworked this using an abstract class that invokes a method on the UI thread that calls .setImageBitmap() but I still get the same behaviour - works fine for all images except the first, unless I move to the next image and back again. Is there a way to force a redraw on the imageview after i set the image?

  - by Andy Barlow

  Hi! I'm trying to join some tables together in MySQL, but I seem to get an error saying: #1066 - Not unique table/alias: 'calendar_jobs' I really want it to select everything from the cal_events, the 2 user bits and just the destination col from the jobs table, but become "null" if there arn't any job.

• I want to be able to derive from a class internally, but disallow class in other assemblies to derive from the class

  - by Rokke

  Hej I have the following setup: Assembly 1 public abstract class XX<T> : XX where T: YY { } public abstract class XX {} Assembly 2 public class ZZ : YY {} public class ZZFriend : XX<ZZ> {} I use this feature in reflection when in YY: public class YY { public Type FindFriend { return GetType().Assembly.GetTypes().FirstOrDefault( t => t.BaseType != null && t.BaseType.IsGenericType && typeof(XX).IsAssignableFrom(t) && t.BaseType.GetGenericArguments().FirstOrDefault() == GetType()); } } I would like do disallow inheritance of the non generic class XX like: public class ZZFriend: XX {} Alternatively, I need a method like (that can be used in the reflection in YY.FindFrind()): public Type F(Type t) { return GetTypeThatIsGeneric(XX, Type genericTypeParameter); } That can be used in YY as: Typeof(XX<ZZ) == F(typeof(GetType()) Hope that makes sense... Thanks in advance Søren Rokkedal

• Pass a parameter from one jsp to another using form.action

  - by Ntz

  I have an ID that I need in the next jsp once the user click a button. I am trying to do the following: FirstJSP.jsp: function getSecond() { var frm = document.getElementById("frm"); frm.action = "**second.jsp?id=myId;"** frm.submit(); } ... form id="frm" ..... input type="button" value="Next" onclick="getSecond()"/ ...... This code takes me to my second page, but if I tried to access the id, it gives me an error since the id is null. I access the id in the second page by: final Long passedId = Long.parseLong(request.getParameter("id")); I think I am not passing the parameter correctly, but I don't know how to do it. Any ideas? Thank you so much!

• Ignoring "Content is not allowed in trailing section" SAXException

  - by Paul J. Lucas

  I'm using Java's DocumentBuilder.parse(InputStream) to parse an XML document. Occasionally, I get malformed XML documents in that there is extra junk after the final > that causes a SAXException: Content is not allowed in trailing section. (In the cases I've seen, the junk is simply one or more null bytes.) I don't care what's after the final >. Is there an easy way to parse an entire XML document in Java and have it ignore any trailing junk? Note that by "ignore" I don't simply mean to catch and ignore the exception: I mean to ignore the trailing junk, throw no exception, and to return the Document object since the XML up to an including the final > is valid.

• Why is the Dependency Property not returning its value?

  - by B-Rad

  I have a MyUserControl with the following Xaml: <TextBox Text="{Binding InputValueProperty}" /> In the MyUserControl.xaml.cs I have: public string InputValue { get { return (string)GetValue(InputValueProperty); } set { SetValue(InputValueProperty, value); } } public static readonly DependencyProperty InputValueProperty = DependencyProperty.Register("InputValueProperty", typeof(string), typeof(MyUserControl)); In my MainWindow.xaml I create a user control: <local:MyUserControl InputValue="My Input" /> Later on in my MainWindow.xaml.cs I am trying to access this string. All instances of MyUserControl are contained in a List and I access them with a foreach. string temp = userControl.InputValue; This is always null. In my MainWindow.xaml I can see the "My Input" in the text box of the user control but I can't ever seem to get it out of there.

• Help Fix a bug - Unexpected T_STRING

  - by thecoshman

  So I have just rebuilt my server, just on local network. Stick my site back on it, try to run the code, and I get a anice T_STRING error. This is all very strange, as I have not changed the code :S <?php $window_ID = -1; if(isset($_POST["window_ID"]) AND $_POST["window_ID"] != null){ $window_ID = trim($_POST["window_ID"]); } ?> This is the start of the file, apter this rather loverly snipit of PHP the rest is just XMl, yet on line 6 appertnlty there is an unexpected T_STRING, which is strange considering all that is on that line is the ?>, then the XML starts up... Any one got any ideas what has gone wrong here? Any chance it ould be magic quotes? I had turned it of before, but I want to now update my code to check for the magic quotes and avoid its stupid actions.

• Alternatives to sign() in sqlite for custom order by

  - by Pentium10

  I have a string column which contains some numeric fields, but a lot are 0, empty string or null. The rest are numbers having different range, all positive. I tried to create a custom order by. The order would be done by two fields. First I would like to order the fields that have this number 0 and then sort by name. So something this would work: select * from table order by sign(referenceid) desc, name asc; But Sqlite lacks the sign() -1/0/1 function, and I am on Android and I can't create user defined functions. What other options I have to get this sort done.
