  • XPath filter not empty attribute

    - by Marcos Buarque
    Hi, I need to filter a XPath expression to grab only a certain attribute as not empty. I tried this: <xsl:template match="DocumentElement/QueryResults[string(@FileName)]"> and this: <xsl:template match="DocumentElement/QueryResults[string-length(@FileName)>0]"> but it did not work. I need the same kind of data returning from the folloing XPath expression... <xsl:template match="DocumentElement/QueryResults"> ... but filtered to avoid items with empty attribute @FileName. Thanks!

  • How to detect when UITextField become empty

    - by Jakub
    Hello, I would like to perform a certain action when UITextField becomes empty (user deletes everything one sign after another or uses the clear option). I thought about using two methods - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string; and - (BOOL)textFieldShouldClear:(UITextField *)textField; from UITextFieldDelegate I'm not sure how to detect the situation when the text field becomes empty? I tried with: if ([textField.text length] == 0) but it does't work as the fisrt of the above methods is called before the sign is deleted from the text field. Any ideas?

  • Retain count = 0 in other function? memory-management problem?

    - by rdesign
    Hey guys, I declared a NSMutableArray in the header-file with: NSMutableArray *myMuArr; and @property (nonatomic, retain) NSMutableArray *myMuArr; In the .m file I've got a delegate from an other class: -(void)didGrabData:(NSArray*)theArray { self.myMuArr = [[[NSMutableArray alloc] initWithArray:myMuArr]retain]; } If I want to access the self.myMuArr in cellForRowAtIndexPath it's empty (I checked the retain count of the array and it's 0) What am I doing wrong? Of course it's released in the dealloc, no where else. I would be very thankfull for any help :0)

Whenever decrypt function calls for _unpad($text) function, i am getting empty as results. Des.php resource: here

  • form not showing for empty records

    - by Chris Hodges
    I have a relatively simple PHP page called editcustomers with 3 columns. The problem I'm having is that the form will show when there is a record in the database and the fields will be populated with that info. When no such records exists, the form is not even shown, eliminating the possibility to insert a record. My page layout is as follows: Column 1 shows a form containing customer information, allowing it to be edited. Column 2 allows ordering of products and showing how many products were ordered Column 3 shows the total paid so far, and the total owing. The code for the page I have at present: <html> <?php $id = $_GET['id']; require_once('connect.php'); $sth = $dbh->query("SELECT * FROM users where id = '$id';"); $sth->setFetchMode(PDO::FETCH_ASSOC); $eth = $dbh->query("SELECT * FROM purchases where id = '$id';"); $eth->setFetchMode(PDO::FETCH_ASSOC); ?> <div id="main"> <div id="left"> <form name="custInfo" action ="process.php" method ="post" > <input type = "hidden" name ="formType" value="custInfo"/> <?php while($row = $sth->fetch()){ ?> <p><input type = "hidden" name ="id" value="<?php echo $row["id"] ?>"/> <p><input type = "text" name ="firstName" size ="30" value=" <?php echo $row["firstName"]?>"/> <p><input type = "text" name ="lastName" size ="30" value="<?php echo $row["lastName"]?>"/> <p><input type = "text" name ="country" size ="30" value="<?php echo $row["country"]?>"/> <p></p> <input type="submit" value="Update" /> <?php }?> </div> <div id="mid"> <form name="custCosts" action ="process.php" method ="post" > <input type = "hidden" name ="formType" value="custCosts"/> <?php while($row = $eth->fetch()){ ?> <p><input type = "hidden" name ="id" value="<?php echo $row["id"] ?>"/> <p><input type = "text" name ="amountOwed" size ="30" value=" <?php echo $row["amountOwed"]?>"/> <p><input type = "text" name ="numAaa" size ="30" value="<?php echo $row["numAaa"]?>"/> <p><input type = "text" name ="numBbb" size ="30" value="<?php echo $row["numBbb"]?>"/> <p></p> <input type="submit" value="Update" /> <?php }?> </div> <div id="right"> <b>Total Balance</b> <p> Money owed: </p> <p> aaa total: </p> <p> bbb total: </p> <p> Total: </p> <input type = "text" name ="pay" size ="20" /></p> <input type="submit" value="Make Payment" /> </div> <?php $dbh =null; ?> </body> </html> And the code for all the database trickery: <?php require_once 'connect.php'; $formType = $_POST['formType']; $id = $_POST['id']; $firstName = $_POST['firstName']; $lastName = $_POST['lastName']; $country = $_POST['country']; $amountOwed = $_POST['amountOwed ']; $numAaa = $_POST['numAaa']; $numBbb = $_POST['numBbb']; if(empty($_POST['id'])) { $sth = $dbh->prepare("INSERT INTO customers (firstName, lastName, country) VALUES ('$firstName', '$lastName', '$country')"); $sth->execute(); } elseif(!empty($_POST['id']) && !isset($_POST['stayCost']) && $_POST['formType'] == 'guestInfo'){ $sth = $dbh->prepare("UPDATE customers SET firstName = '$firstName', lastName = '$lastName', country = '$country' WHERE id = '$id'"); $sth->execute(); }elseif(!empty($_POST['id']) && isset($_POST['stayCost']) && $_POST['formType'] == 'guestInfo'){ $sth = $dbh->prepare("INSERT INTO purchases (id, amountOwed, numAaa, numBbb) VALUES ('$id', '$amountOwed', '$numAaa', '$numBbb'"); $sth->execute(); }elseif(!empty($_POST['id']) && $_POST['formType'] == 'guestCosts'){ $sth = $dbh->prepare("UPDATE purchases SET amountOwed= '$amountOwed', numAaa = '$numAaa', numBbb= '$numBbb' WHERE id = '$id'"); $sth->execute(); } $dbh =null; ?> Why does the form not even display if there is no record? An error or something I might understand....but the form is still in the HTML and should still be being output, from what I can see. Why is this not the case?

  • Create empty C# event handlers automatically

    - by TomA
    It is not possible to fire an event in C# that has no handlers attached to it. So before each call it is necessary to check if the event is null. if ( MyEvent != null ) { MyEvent( param1, param2 ); } I would like to keep my code as clean as possible and get rid of those null checks. I don't think it will affect performance very much, at least not in my case. MyEvent( param1, param2 ); Right now I solve this by adding an empty inline handler to each event manually. This is error prone, since I need to remember to do that etc. void Initialize() { MyEvent += new MyEvent( (p1,p2) => { } ); } Is there a way to generate empty handlers for all events of a given class automatically using reflection and some CLR magic?

  • Deserialize Xml with empty elements in C#

    - by user204086
    Trying to deserialize some xml snippits into objects. The problem is that I'm getting an invalid format on every empy element tag. I can deserialize the object no problem when all of the elements have values. Or the empty elements are ommitted. Xml Snippit: <foo><propOne>1</propOne><propTwo /></foo> C# Class: [Serialilbe()] public class foo { public foo(){} [XmlElementAttribute(IsNullable = true)] public int? propOne {get;set;} [XmlElementAttribute(IsNullable = true)] public int? propTwo {get;set;} } Is there a setting on the class I can make to adjust the parsing? or Is there an easy way I can apply xsl to remove these elements? or Should I use regEx to remove the empty elements be fore desrializing? or an even better way?

  • python dict.fromkeys() returns empty

    - by slooow
    I wrote the following function. It returns an empty dictionary when it should not. The code works on the command line without function. However I cannot see what is wrong with the function, so I have to appeal to your collective intelligence. def enter_users_into_dict(userlist): newusr = {} newusr.fromkeys(userlist, 0) return newusr ul = ['john', 'mabel'] nd = enter_users_into_dict(ul) print nd It returns an empty dict {} where I would expect {'john': 0, 'mabel': 0}. It is probably very simply but I don't see the solution.

  • How to empty a socket in python?

    - by luc
    I need to empty the data on a socket (making sure that there is nothing to receive). Unfortunately, there is no function for this in the python socket module. I've implemented something this way: def empty_socket(sock): """remove the data present on the socket""" input = [sock] while 1: inputready, o, e = select.select(input,[],[], 0.0) if len(inputready)==0: break for s in inputready: s.recv(1) What do you think? Is there a better way to do that? Update: I don't want to change the socket timeout. What's why i prefer a select to a read. Update: The original question was using the 'flush' term. It seems that 'empty' is a better term. Update - 2010-02-27 : I've noticed a bug after when the pair has closed. The inputready is always filled with the sockets. I fixed that by adding a maximum number of loops. Is there a better fix?

  • Jquery UI Dialog Empty On Auto-Open

    - by user1019588
    I am having a somewhat strange error with my jquery dialog. When I have it autoopen, the dialog box is completely empty. If I exit out of the dialog and then reopen (through the standard dialog open event) the content appears. The jquery setup: $("#content_locker").dialog({ autoOpen: true, modal: true, height: 600, width: 800 }); Here you can see the webpage that I am working on (it is a link-shortening service). The dialog div starts on line 148 of the source: <div id="content_locker" title="Exclusive Content"> You will see that the dialog is empty. If you exit out and click on the unlock button, the proper html is there. Any ideas?

  • AutoCompleteTextView not displaying result even when the ArrayAdapter is updated

    - by cant0na
    I'm trying to get an AutoCompleteTextView(ACTV) to display results I'm a getting from a network resource. I have set the completion-treshold to 2 and I can see that the request is fired when I enter to characters. The result I am getting is the correct one. Lets say I write "ca", and I get the result "car" as an autocompletion. I have a callback function which receives the result from an AsyncTask and puts the result into the ArrayAdapter. Then I call .showDropDown() on the ACTV and an empty dropdown is shown (half the size of a normal element). Then if I enter the last letter "r" and the ACTV shows "car", the dropdown is shown and the result is suddenly in the list. The same happens if I have entered two characters (which returns a valid result), and the remove the last letter. When the letter is removed, "car" is shown as an autocompletion value. Has anyone had this problem? It looks like the adapter is filled with the result, but the result does not show until the next action I do. I have also tried to run .notifyDataSetChanged() after I have added the result to the adapter, but that should not be needed, or?

  • PDO empy result from SELECT when using AND

    - by Jurgen
    Hello, I've come upon a rather interesting thing, which I can't seem to figure out myself. Everytime when executing a SQL statement which contains a '... AND ...' the result is empty. Example: echo('I have a user: ' . $email . $wachtwoord . '<br>'); $dbh = new PDO($dsn, $user, $password); $sql = 'SELECT * FROM user WHERE email = :email AND wachtwoord= :wachtwoord'; $stmt = $dbh->prepare($sql); $stmt->bindParam(:email,$email,PDO::PARAM_STR); $stmt->bindParam(:wachtwoord,$wachtwoord,PDO::PARAM_STR); $stmt->execute(); while($row = $stmt->fetchObject()) { echo($row-email . ',' . $row-wachtwoord); $user[] = array( 'email' = $row-email, 'wachtwoord' = $row-wachtwoord ); } The first echo displays the correct values, however the line with echo($row->email . ',' . $row->wachtwoord); is never reached. A few things I want to add: 1) I am connected to the database since other queries work, only the ones where I add an 'AND' after my 'WHERE's fail. 2) Working with the while works perfectly with queries that do not contain '... AND ...' 3) Error reporting is on, PDO gives no exceptions on my query (or anything else) 4) Executing the query directly on the database does give what I want: SELECT * FROM user WHERE email = '[email protected]' AND wachtwoord = 'jurgen' I can stare at it all day long again (which I already did once, but I managed to work around the 'AND'), but maybe one of you can give me a helping hand. Thank you in advance. Jurgen

  • How can I filter using the current value of a text box in a jQuery selector?

    - by spudly
    I have a validation script that checks for data-* attributes to determine which fields are required. If an element has the 'data-required-if' attribute (which has a jQuery selector as it's value), it checks to see if any elements are found that match that selector. If any are found, the field is required. It does something similar to the following: $('[data-required-if]').each(function () { var selector = $(this).attr('data-required-if'), required = false; if ( !$(selector).length ) { required = true; // do something if this element is empty } }); This works great, but there's a problem. When you use the attribute selector to filter based on the current value of a text field, it really filters on the initial value of the text field. <input type='text' id='myinput' value='initial text' /> <input type='text' id='dependent_input' value='' data-required-if="#myinput[value='']" /> // Step 1: type "foobar" in #myinput // Step 2: run these lines of code: <script> $('#myinput').val() //=> returns "foobar" $('#myinput[value="foobar"]').length //=> returns 0 </script> I understand why it's doing that. jQuery probably uses getAttribute() in the background. Is there any other way to filter based on the current value of an input box using purely jQuery selectors?

  • Macbook shuts down when battery is empty (should have went to sleep)

    - by the_great_monkey
    In the past few weeks, my macbook shuts down when the battery dies. The battery does not even die at 0%, sometimes it shuts down at 5% or 10% remaining. I tried calibrating the baterry following this website: http://support.apple.com/kb/HT1490. But it does not really help. I regularly use battery in my macbook, I'd say I use around 2-3 cycles a week. My charge cycles is 440 cycles, and my current battery capacity is 3400mAh from the original 4100mAh. I have 2008 unibody Macbook. Does anyone know how to make it goes to sleep before the battery's dead? EDIT: The OS seems the think that the battery is ok...

  • Trailing dots in url result in empty 404 page on IIS

    - by Peter Hahndorf
    I have an ASP.NET site on IIS8, but IIS7.5 behaves exactly the same. When I enter a URL like: mysite.com/foo/bar.. I get the following error with a '500 Internal Server Error' status code: even though I have custom error pages set up for 500 and 404 and I don't see anything wrong with my custom error page. In my web.config system.web node I have the following: <customErrors mode="On"> <error statusCode="404" redirect="/404.aspx" /> </customErrors> If I remove that section, I get a 404.0 response back but the page itself is blank. In web.config system.webServer I have: <httpErrors errorMode="DetailedLocalOnly"> <remove statusCode="404" subStatusCode="-1" /> <error statusCode="404" prefixLanguageFilePath="" path="404.html" responseMode="File" /> </httpErrors> But whether that is there or not, I get the same blank 404.0 page rather than my expected custom error page, or at least an internal IIS message. So first of all why is the asp.net handler picking up a request for '..' (also works with one or more trailing dots) If I remove the following handler from applicacationHost.config: <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" responseBufferLimit="0" /> I get my expected custom 404 page, but of course removing that handler breaks routing in asp.net among other things. Looking at the failure trace I see: Windows Authentication is disabled for the site, so why is that module even in the request pipeline? For now my fix is to use the URL Rewrite module with the following rule: <rewrite> <rules> <rule name="Trailing Dots" stopProcessing="true"> <match url="\.+$" /> <action type="Rewrite" url="/404.html" appendQueryString="false" /> </rule> </rules> </rewrite> This works okay, but I wonder why IIS/ASP.NET behaves this way?
