  • applying a var to an if statement jquery

    - by Dirty Bird Design
    Need to apply a var to a statement if its conditions are met, this syntax isn't throwing errors but its not working. <script type="text/javascript"> $(document).ready(function(){ var action_is_post = false; //stuff here $(this).ready(function () { if ($("#stepDesc0").is(".current")) { action_is_post = true; } }); //stuff here </script> should I use something other than .ready? Do I even need the $(this).ready(function ()... part? I need it to apply the var when #stepDesc0 has the class current.

  • Changing floating point behavior in Python to Numpy style.

    - by Tristan
    Is there a way to make Python floating point numbers follow numpy's rules regarding +/- Inf and NaN? For instance, making 1.0/0.0 = Inf. >>> from numpy import * >>> ones(1)/0 array([ Inf]) >>> 1.0/0.0 Traceback (most recent call last): File "<stdin>", line 1, in <module> ZeroDivisionError: float division Numpy's divide function divide(1.0,0.0)=Inf however it is not clear if it can be used similar to from __future__ import division.

  • How can I make a read-only ObservableCollection property?

    - by thrag
    I'd like to expose a property on a view model that contains a list of objects (from database). I need this collection to be read-only. That is, I want to prevent Add/Remove, etc. But allow the foreach and indexers to work. My intent is to declare a private field holding the editable collection and reference it with a read-only Public Property. As follows public ObservableCollection<foo> CollectionOfFoo { get { return _CollectionOfFoo; } } However, that syntax just prevents changing the reference to the collection. It doesn't prevent add/remove, etc. What is the right way to accomplish this?

  • best way to filter out non-representational elements

    - by nonano
    Hi there, I am using phpQuery in order to apply some twaks to editorial content. As its syntax is the same as jQuery, I consider this a dom scripting issue. To get rid of elements which are not representing anything, but wrapping other stuff (like the div in <div><p>blah</p></div> I came up with this selector: ['div:not([align][class][id][style][title][dir][lang][onclick][ondblclick][onmousedown] [onmouseup][onmouseover][onmousemove][onmouseout][onkeypress][onkeydown][onkeyup])'] which looks quite monstrous for a selector simply aming on Divs which just do not have any (valid) attribute. I guess there must be a more straight-forward way to accomplish that, right? Edit: Oh, and I just noticed that it even doesn't do wat I intended to ...

  • How do you escape parentheses in a Binding indexer

    - by Chris S
    I have the following XAML: <Grid x:Name="LayoutRoot" Background="White" DataContext="{Binding Source={StaticResource MyDataKey}}"> <TextBox Name="_myId" Text="{Binding MyDictionary[(Textbox.Name)]" /> </Grid> But it thinks the key in my dictionary is called "(Textbox.Name)", instead of "_myId". The format below works, where I have a property in my class called "_myId": <TextBox Name="_myId" Text="{Binding (Textbox.Name)" /> I've tried using ^ and \ to escape the brackets. Is this syntax supported? I'm trying to avoid duplication of the name in two attributes.

  • In WPF XAML how can I concatenate 2 constants so I can use pre-define paths?

    - by toaster24
    I'm new to XAML, so presume I'm missing something simple. I want to replace the path part of the source path with a c# constant for easier path management, for example I have: <Image Source="/Images/Themes/Buttons/MyPicture.png" /> and in another class I have my constant defined: public static readonly string UriImagesButtons = "/Images/Big/PNG/"; I want to have something along the lines of: <Image Source="{static:UriImagesButtons + MyPicture.png}" /> This means that I can change the path globally at a stroke if the need arises. What's the syntax to do this?

  • WebView not responding when called from a method

    - by AragornSG
    I have an app with tabbar and webview. I'm trying to make the app come back to default url each time user taps the bar. Right now I'm intercepting taps and launching a method, however it's not affecting my webview. The same syntax for calling webview from awakeFromNib works, so I don't have a clue what's up. I suspect it's something to do with how I call the method, but I don't know what. Here is the code: #import "SecondViewController.h" @implementation SecondViewController - (void)awakeFromNib { NSString *loadURL = [NSString stringWithFormat:@"http://pageurl"]; // [secondView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:loadURL]]]; SecondViewController *ptr = [[SecondViewController alloc] init]; [ptr goToPage]; } - (void) goToPage { NSLog(@"go to page"); NSString *newURL = [NSString stringWithFormat:@"http://pageurl"]; [secondView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:newURL]]]; } Thanks fot your help!

  • Uploading a Website

    - by 01010011
    Hi, This is my first time building a website and using CodeIgniter for a school project. I was wondering whether you have any tips on uploading CI to a free web host , my database, free webhosting and basic security tips. Can I just upload the entire CI folder? Or do I have to upload individual files (God no!)? What are my options? What about my MySQL database - do I just upload my mysqldump to the webhost? Also, can you recommend a good free webhost. I was thinking about 000webhost. Any basic tips on security would also be appreciated (I've implemented many of the form_validation rules like xss_clean for starters) Any other suggestions will be more than welcome. Thanks!

  • MySQL - Counting rows in preparation for greatest-n-per-group not working?

    - by John M
    Referring to SO and other sites have given me examples of how to use MySQL to create a 'greatest-n-per-group' query. My variant on this would be to have a query that returns the first 3 rows of each category. As the basis for this I need to sort my data into a usable sequence and that is where my problems start. Running just the sequence query with row numbering shows that changes in category are mostly ignored. I should have 35 categories returning rows but only 5 do so. My query: set @c:=0; set @a:=0; SELECT IF(@c = tdg, @a:=@a+1, @a:=1) AS rownum, (@c:=tdg) , julian_day, sequence, complete, year, tdg FROM tsd WHERE complete = 0 order by tdg, year, julian_day, sequence Do I have a syntax mistake with this query?

  • antlr: How to rewrite only specific

    - by user1293945
    I am sure antlr can solve my problem, but can't figure out how to implement it, even high level. I rapidly got caught into syntax problems of antlr itself. My grammar is quite simple and made of following tokens and rules. Don't really need to go in their details here. The evaluator resolves to expressions, which finally resolve to IDENT: evaluator : expression EOF! ; ... ... term : PARTICIPANT_TYPE(IDENT | '('! expression ')'! | max | min | if_ | NUMBER)+ ; Now, I would like to analyse and rewrite the 'term', so that IDENT tokens (and them only) get re-written with the PARTICIPANT_TYPE. All the others should simply remain the same.

  • SSRS and cached reports

    - by Tabloo Quijico
    Hi, I'm opening an SSRS2008 report using the http://server/reportserver/... syntax, outputting directly a PDF copy. This report has several parameters. The problem is that, despite making changes to the report, and clearing the browser's temporary files cache.. if I request the same report (i.e. same parameters) - the old report is returned. In the report execution properties, I have "Always run this report with the most recent data" and "Do not cache temporary copies of this report" selected. It's not just a case of caching data, but the entire report (including formatting, e.g. I deleted a page from the report yet it was still being shown...) and as I haven't specifically chosen to perform any caching I'm a little concerned and clearly don't fully understand what's going on! Any tips?

  • ctrl-c does not copy text on a webpage

    - by aepheus
    I've come across this several times, ctrl-c randomly does not copy. I think it's caused by javascript or maybe some odd html syntax. I never spent the time to track down what caused it. Anyone know the typical/common causes of ctrl-c not working (to copy) on a website? Speaking from a developers standpoint. What do we developers end up doing to break ctrl-c? Just to clarify, I'm not interested in preventing copying. I'm trying to do the opposite, occasionally I find I've done something that is preventing ctrl-c from copying text, and that is not very user friendly on a text heavy site.

  • JAVA-SQL- Data Migration - ResultSets comparing Failing JUnit test

    - by user1865053
    I CANNOT get this JUnit Test to pass for the life of me. Can somebody point out where this has gone wrong. I am doing a data migration(MSSQL SERVER 2005), but I have the sourceDBUrl and the targetDCUrl the same URL so to narrow it down to syntax errors. So that is what I have, a syntax error. I am comparing the results of a table for the query SELECT programmeapproval, resourceapproval FROM tr_timesheet WHERE timesheetid = ? and the test always fails, but passes for other junit tests I have developed. I created 3 diffemt resultSetsEqual methods and none work. Yet, some other JUnit tests I have developed have PASSED. THE QUERY: SELECT timesheetid, programmeapproval, resourceapproval FROM tr_timesheet Returns three columns timesheetid (PK,int, not null) (populated with a range of numbers 2240 - 2282) programmeapproval (smallint,not null) (populated with the number 1 in every field) resourceapproval (smallint, not null) (populated with a number 1 in every field) When I run the query that is embedded in the code it only returns one row with the programmeapproval and resourceapproval columns and both field populated with the number 1. I have all jdbc drivers correctly installed and tested for connectivity. The JUnit Test is failing at this point according to the IDE. assertTrue(helper.resultSetsEqual2(sourceVal,targetVal)); This is the code: /*THIS IS A JUNIT CLASS****? package a7.unittests.dao; import static org.junit.Assert.assertTrue; import java.sql.Connection; import java.sql.PreparedStatement; import java.sql.ResultSet; import java.sql.Types; import org.junit.Test; import artemispm.tritonalerts.TimesheetAlert; public class UnitTestTimesheetAlert { @Test public void testQUERY_CHECKALERT() throws Exception{ UnitTestHelper helper = new UnitTestHelper(); Connection con = helper.getConnection(helper.sourceDBUrl); Connection conTarget = helper.getConnection(helper.targetDBUrl); PreparedStatement stmt = con.prepareStatement("select programmeapproval, resourceapproval from tr_timesheet where timesheetid = ?"); stmt.setInt(1, 2240); ResultSet sourceVal = stmt.executeQuery(); stmt = conTarget.prepareStatement("select programmeapproval, resourceapproval from tr_timesheet where timesheetid = ?"); stmt.setInt(1,2240); ResultSet targetVal = stmt.executeQuery(); assertTrue(helper.resultSetsEqual2(sourceVal,targetVal)); }} /*END**/ /*THIS IS A REGULAR CLASS**/ package a7.unittests.dao; import java.sql.Connection; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.ResultSetMetaData; import java.sql.SQLException; public class UnitTestHelper { static String sourceDBUrl = "jdbc:sqlserver://127.0.0.1:1433;databaseName=a7itm;user=a7user;password=a7user"; static String targetDBUrl = "jdbc:sqlserver://127.0.0.1:1433;databaseName=a7itm;user=a7user;password=a7user"; public Connection getConnection(String url)throws Exception{ return DriverManager.getConnection(url); } public boolean resultSetsEqual3 (ResultSet rs1, ResultSet rs2) throws SQLException { int col = 1; //ResultSetMetaData metadata = rs1.getMetaData(); //int count = metadata.getColumnCount(); while (rs1.next() && rs2.next()) { final Object res1 = rs1.getObject(col); final Object res2 = rs2.getObject(col); // Check values if (!res1.equals(res2)) { throw new RuntimeException(String.format("%s and %s aren't equal at common position %d", res1, res2, col)); } // rs1 and rs2 must reach last row in the same iteration if ((rs1.isLast() != rs2.isLast())) { throw new RuntimeException("The two ResultSets contains different number of columns!"); } } return true; } public boolean resultSetsEqual (ResultSet source, ResultSet target) throws SQLException{ while(source.next()) { target.next(); ResultSetMetaData metadata = source.getMetaData(); int count = metadata.getColumnCount(); for (int i =1; i<=count; i++) { if(source.getObject(i) != target.getObject(i)) { return false; } } } return true; } public boolean resultSetsEqual2 (ResultSet source, ResultSet target) throws SQLException{ while(source.next()) { target.next(); ResultSetMetaData metadata = source.getMetaData(); int count = metadata.getColumnCount(); for (int i =1; i<=count; i++) { if(source.getObject(i).equals(target.getObject(i))) { return false; } } } return true; } } /END***/ /*PASTED NEW CLASS - THIS IS A JUNIT TEST CLASS*/ package a7.unittests.dao; import static org.junit.Assert.*; import java.sql.Connection; import java.sql.DriverManager; import org.junit.Test; public class TestDatabaseConnection { @Test public void testConnection() throws Exception{ UnitTestHelper helper = new UnitTestHelper(); Connection con = helper.getConnection(helper.sourceDBUrl); Connection conTarget = helper.getConnection(helper.targetDBUrl); assertTrue(con != null && conTarget != null); } } /**END***/

  • Making a PHP object behave like an array?

    - by Mark Biek
    I'd like to be able to write a PHP class that behaves like an array and uses normal array syntax for getting & setting. For example (where Foo is a PHP class of my making): $foo = new Foo(); $foo['fooKey'] = 'foo value'; echo $foo['fooKey']; I know that PHP has the _get and _set magic methods but those don't let you use array notation to access items. Python handles it by overloading __getitem__ and __setitem__. Is there a way to do this in PHP? If it makes a difference, I'm running PHP 5.2.

  • c++ Array passing dilemma

    - by Thomas
    Hi, I am writing a function that takes a string, string pointer and an int. The function splits the string based on a set of rules and puts each token into an array. I need to return the array out of the function with the number of elements in the int variable etc. I am stuck as to how I return the array as I can not use auto other wise it is destroyed and I am reluctant to use new as I feel this is patchy. I have other ideas on how to go about this but would like to see how other people go about this first. I could also be wrong and it could be possible to pass an auto out of an array. I can also not use vectors so there goes a copy constructor.

  • How to style just one type of input field without also affecting other input types with CSS

    - by James
    Is there a way to write style rules that will only influence text fields. Suppose I have the following: <div id="helloDiv"> <input type="text" name="something" /><br /> <input type="checkbox" name="somethingElse" /><br /> <input type="submit" name="go" /> </div> div#helloDiv input { border: 1px solid red; } The problem with the above CSS rule is that it will affect ALL input fields not just input text but also radio buttons, submit buttons, etc. So is there a cross browser solution to affect just one type of input field within a div or other page element (without resorting to assigning the input fields styles individually).

  • mod_rewrite with GET requests

    - by iMaster
    I have mod_rewrite working on most of my site. Right now I have a search that normally would point to search.php?keyword=KEYWORD And I'm trying to rewrite that to search/?keyword=KEYWORD Just to make it a little bit cleaner. So here's my mod_rewrite. (There are other rules I'm just posting the one that isn't working.) RewriteRule ^search/?keyword=([^/\.]+)/?$ search.php?search=$1 When I type a search in the address bar way I want it to be, I get a page telling me its a "broken link" (I'm guessing that that's Chrome's equivalent of a 404 error). So what am I doing wrong? I think that the problem is the '=' or the '?' sign in the rule (the first part) because when I take the ?keyword= part out, it works. Does that make sense?

  • How do I set properties related to the calling method's scope?

    - by Thiado de Arruda
    I'm not looking for a way to associate values with a thread using the 'SetData' method. I need to store some kind of data that will only exist during the scope of a calling method, could be the immediate parent or any other call that is made down on the stack. For example: void SomeMethod() { string someInfo = "someInfo"; SomeOtherMethod(); object data = GetDataOnCurrentScope("someKey"); } void SomeOtherMethod() { SetDataOnParentScope("someKey", somevalue); } In this case both the 'someInfo' local variable and the data set with the "someKey" key will disapear after 'SomeMethod' returns. Is something like this possible? This may go against the rules of a stack, but who knows if someone has an idea...

  • scala xml rewrite rule (or, simple pattern help)

    - by williamstw
    I'm missing some fairly simple syntax I gather. I'm trying to rewrite an element label to something else and keep everything else intact. object htmlRule extends RewriteRule { override def transform(n: Node): Seq[Node] = n match { case Elem(prefix, "document", attribs, scope, child@_*) => Elem(prefix, "html", attribs, scope, child) case other => other } } Now, I ask for an explanation of two things: 1) What exactly does "child@_*" mean in plain English? 2) How can I capture the value of "child@_*" and just let it pass right through to the new element? Currently, I get the following error, which makes sense. [error] found : Seq[scala.xml.Node] [error] required: scala.xml.Node [error] Elem(prefix, "html", attribs, scope, child) I'm not wedded to this either, so if there's a better way to simply change the element name of a specific node, let's here it... Thanks, --tim
