  • How do I reference sqlite db column to use in update statement

    - by user244190
    I am trying to update a datetime column in an android sqlite db to use international date format (yyyy-mm-dd) instead of the current format (mm/dd/yyyy). I want to use the sqlite date() function to reformat the current value of the column. I thought it would be as simple as the following: update tblename set thedate = date(thedate) but the above does not work. How would i write the sql statement to accomplish this? thanks patrick

  • detecting object-reference duplication across JavaScript files

    - by AnC
    I have a number of files with contents like this: function hello() { ... element1.text = foo.locale.lorem; element2.text = foo.locale.ipsum; ... elementn.text = foo.locale.whatever; ... } function world() { ... var label = bar.options.baz.blah; var toggle = bar.options.baz.use_toggle; ... } This could be written more efficiently, and also be more readable, by creating a shortcut to the locale object: function hello() { var loc = foo.locale; ... element1.text = loc.lorem; element2.text = loc.ipsum; ... elementn.text = loc.whatever; ... } function world() { var options = bar.options.baz; ... var label = options.blah; var toggle = options.use_toggle; ... } Is there a simple way to detect occurrences of such duplication for any arbitrary object (it's not always as simple as "locale", or foo.something)? Basically, I wanna know where lengthy object references appear two or more times within a function. Thanks!

  • if a JAR is placed on app servers's classpath how do we reference it from JSP

    - by Omnipresent
    On our application we are getting an error saying: PWC6117: File "/struts-tags" not found code in the file thats giving error is: <%@ taglib prefix="s" uri="/struts-tags" %> This file is in struts2-core.jar which is placed on the classpath of the app server (Sun 9.1). The code will work fine and not complain when the jar is actually in WEB-INF/lib of the application, compared to being on classpath of the appserver. But we can not change that. it has to be on appservers classpath. But how should we change our code so that this error goes away? I can create mapping in my web.xml so that tag uri's are change. but what should taglib-location be changed to? so that it references to app servers classpath? <taglib> <taglib-uri>/WEB-INF/struts-tags.tld</taglib-uri> <taglib-location>/WEB-INF/struts-tags.tld</taglib-location> </taglib>

  • Using a join with three tables when a field might be null

    - by John
    Hello, The code below works great. It combines data from two MySQL tables. I would like to modify it by pulling in some data from a third MySQL table called "comment." In the HTML table below, "title" is a field in the MySQL table "submission." Every "title" has a corresponding "submissionid" field. The field "submissionid" is also found in the "comment" MySQL table. In the HTML table below, I would like "countComments" to equal the number of times a field called "commentid" appears in the MySQL table "comment" for any given "submissionid," where the "submissionid" is the same in both the "submission" and "comment" tables, and where the "submissionid" corresponds to the "title" being used. Here's the catch: if there is no row in the MySQL table "comment" that corresponds with the "submissionid" being used for "table", I would like "countComments" to equal to zero. How can I do this? Thanks in advance, John $sqlStr = "SELECT s.loginid, s.title, s.url, s.displayurl, l.username FROM submission AS s, login AS l WHERE s.loginid = l.loginid ORDER BY s.datesubmitted DESC LIMIT 10"; $result = mysql_query($sqlStr); $arr = array(); echo "<table class=\"samplesrec\">"; while ($row = mysql_fetch_array($result)) { echo '<tr>'; echo '<td class="sitename1"><a href="http://www.'.$row["url"].'">'.$row["title"].'</a></td>'; echo '</tr>'; echo '<tr>'; echo '<td class="sitename2"><a href="http://www...com/sandbox/members/index.php?profile='.$row["username"].'">'.$row["username"].'</a><a href="http://www...com/sandbox/comments/index.php?submission='.$row["title"].'">'.$row["countComments"].'</a></td>'; echo '</tr>'; } echo "</table>";

  • DOMNode reference doesn't work anymore after appending it to another element twice

    - by Robbie Groenewoudt
    Hi, I'm using the a wrapper around the PHP5-class DOMDocument to generate my HTML. This makes it easy to modify the HTML by using the DOM. An example is creating element #1 and adding it to the element #2 and still be able to modify element #1 directly. A problem arises however with the following: Element #1 is added to element #2 Element #2 is added to element #3 Element #1 is modified but no changes are visible in the DOM of element #3 (which contains #1 and #2) A simplified sample code: <?php $doc1 = new DOMDocument(); $el1 = $doc1->createElement('h1', 'Hello'); $doc1->appendChild($el1); $doc2 = new DOMDocument(); $el2 = $doc2->createElement('h2', 'World'); $doc2->appendChild($el2); $doc3 = new DOMDocument(); $el3 = $doc3->createElement('h3', 'Today'); $doc3->appendChild($el3); // Import el1 into el2 $el1 = $doc2->importNode($el1, true); $el2->appendChild( $el1 ); $doc1 = $doc2; // Import el2 into el3 $el2 = $doc3->importNode($el2, true); //$el1 = $doc3->importNode($el1, true); Necessary? $el3->appendChild($el2); $doc2 = $doc3; // Modify el1 $el1->nodeValue = "Boo"; // This doesn't work? //$el2->nodeValue = "Boo"; // Changing element2 or 3 works... // Display result echo $doc3->saveHTML(); ?>` Any idea's on why modifying $el1 won't work? (While $el2 works fine) Or an easy way to set $el1 to the right element?

  • UnsupportedOperationException on Collection

    - by Duke Vador
    While studying the Collection API, we find that some methods (add, remove,...) may throw a java.lang.UnsupportedOperationException if the current implementation of the Collection does not support those functionalities. Is there,actually, in the JDK, a concrete Collection that does not support those methods ? Thanks a lot for your answers.

  • Exception if there is IBOutlet in view controller created by initWithNibName

    - by Kail
    When I create a Navigation-based application, the second view controller is created with initWithNibName, if I add a label onto the second view and connect it with IBOutlet in the second view controller. After I navigate to the second view by clicking table cell, and then back to the root view, the application aborts - send message retainCount to a freed object. I know this is caused by the IBOutlet label, which is retained, set nil in viewDidUnload and dealloc in dealloc. But I don't know why, and if I wanna still use IBOutlet, what can I do? Not dealloc it in viewcontroller's dealloc? Anybody could help? Thank you.

  • template pass by const reference

    - by 7vies
    Hi, I've looked over a few similar questions, but I'm still confused. I'm trying to figure out how to explicitly (not by compiler optimization etc) and C++03-compatible avoid copying of an object when passing it to a template function. Here is my test code: #include <iostream> using namespace std; struct C { C() { cout << "C()" << endl; } C(const C&) { cout << "C(C)" << endl; } ~C() { cout << "~C()" << endl; } }; template<class T> void f(T) { cout << "f<T>" << endl; } template<> void f(C c) { cout << "f<C>" << endl; } // (1) template<> void f(const C& c) { cout << "f<C&>" << endl; } // (2) int main() { C c; f(c); return 0; } (1) accepts the object of type C, and makes a copy. Here is the output: C() C(C) f<C> ~C() ~C() So I've tried to specialize with a const C& parameter (2) to avoid this, but this simply doesn't work (apparently the reason is explained in this question). Well, I could "pass by pointer", but that's kind of ugly. So is there some trick that would allow to do that somehow nicely? EDIT: Oh, probably I wasn't clear. I already have a templated function template<class T> void f(T) {...} But now I want to specialize this function to accept a const& to another object: template<> void f(const SpecificObject&) {...} But it only gets called if I define it as template<> void f(SpecificObject) {...}

  • Writing exceptions in multihreaded windows service to event log

    - by Ziplin
    I have a multithreaded windows service that will unpredictably stop running once every 24 hours or so. I am writing to the event log and that's going through just fine, but whenever the service crashes there are no messages in the event log (even that the service stopped, despite having AutoLog=true). Is there a way to have uncaught exceptions written straight to the log, even if they aren't in the original thread?

  • PostgreSQL storing paths for reference in scripts

    - by Brian D.
    I'm trying to find the appropriate place to store a system path in PostgreSQL. What I'm trying to do is load values into a table using the COPY command. However, since I will be referring to the same file path regularly I want to store that path in one place. I've tried creating a function to return the appropriate path, but I get a syntax error when I call the function in the COPY command. I'm not sure if this is the right way to go about it, but I'll post my code anyway. COPY command: COPY employee_scheduler.countries (code, name) FROM get_csv_path('countries.csv') WITH CSV; Function Definition: CREATE OR REPLACE FUNCTION employee_scheduler.get_csv_path(IN file_name VARCHAR(50)) RETURNS VARCHAR(250) AS $$ DECLARE path VARCHAR(200) := E'C:\\Brian\\Work\\employee_scheduler\\database\\csv\\'; file_path VARCHAR(250) := ''; BEGIN file_path := path || file_name; RETURN file_path; END; $$ LANGUAGE plpgsql; If anyone has a different idea on how to accomplish this I'm open to suggestions. Thanks for any help!

  • download file exception handling

    - by klaus-vlad
    Hi, In my application I download several critical files from a server, and I want to write some code that handles the case where the a file download didn't complete for a reason or other ,to retry downloading it at next startup. The function that downloads a file at a time however throws only MalformedURLException and IOException , but if these exceptions are thrown that means that the download didn't even begin. How should I arrange things so I can treat the case where a download failed , even if it began ? download(String file) throws MalformedURLException ,IOException { }

  • xUnit false positive when comparing null terminated strings

    - by mr.b
    I've come across odd behavior when comparing strings. First assert passes, but I don't think it should.. Second assert fails, as expected... [Fact] public void StringTest() { string testString_1 = "My name is Erl. I am a program\0"; string testString_2 = "My name is Erl. I am a program"; Assert.Equal<string>(testString_1, testString_2); Assert.True(testString_1.Equals(testString_2)); } Any ideas?
