  • update dialog title for each click

    - by Scarface
    Hey guys I have a quick question, I have a dialog box that has multiple links with different attributes. Each time a link is clicked, the attribute src is printed inside of the dialog box so that each link has a unique output in the dialog. My problem is simply that only the first src title is in every box and I would like to change that as well with each click. I separated the line containing title to show the problem. If anyone has any ideas I would appreciate it. <a class="open" src="something" title="Click to play">link</a> <a class="open" src="something else" title="Click to play">link2</a> $('.open').click(function() { src=$(this).attr('src'); $('#show').html(''+src+''); $(\"#show\").dialog({hide: 'clip', width: 400,height: 150,position: 'center', show: 'clip',stack: true,title: ''+src+'', minHeight: 25, minWidth: 100, autoOpen: false,resizable:false}); $('#show').dialog('open'); })

  • Composite pattern in C++ problem

    - by annouk
    Hello! I have to work with an application in C++ similar to a phone book: the class Agenda with an STL list of Contacts.Regarding the contacts hierarchy,there is a base-class named Contact(an abstract one),and the derived classes Friend and Acquaintance(the types of contact). These classes have,for instance, a virtual method called getName,which returns the name of the contact. Now I must implement the Composite pattern by adding another type of contact,Company(being derived from Contact),which also contains a collection of Contacts(an STL list as well),that can be either of the "leaf" type(Friends or Acquaintances),or they can be Companies as well. Therefore,Company is the Compound type. The question is: how and where can I implement an STL find_if to search the contact with a given name(via getName function or suggest me smth else) both among the "leaf"-type Contact and inside the Company collection? In other words,how do I traverse the tree in order to find possible matches there too,using an uniform function definition? I hope I was pretty clear...

  • "public" or "private" attribute in Python ? What is the best way ?

    - by SeyZ
    Hi ! In Python, I have the following example class : class Foo: self._attr = 0 @property def attr(self): return self._attr @attr.setter def attr(self, value): self._attr = value @attr.deleter def attr(self): del self._attr As you can see, I have a simple "private" attribute "_attr" and a property to access it. There is a lot of codes to declare a simple private attribute and I think that it's not respecting the "KISS" philosophy to declare all attributes like that. So, why not declare all my attributes as public attributes if I don't need a particular getter/setter/deleter ? My answer will be : Because the principle of encapsulation (OOP) says otherwise! What is the best way ? Thanks !

  • Create unique links for indvidual elements of a PHP generated table

    - by typoknig
    I have a table generated from some PHP code that lists a SMALL amount of important information for employees. I want to make it so each row, or at least one element in each row can be clicked on so the user will be redirected to ALL of the information (pulled from MySQL database) related to the employee who was clicked on. I am not sure how would be the best way to go about this, but I am open to suggestions. I would like to stick to PHP and/or JavaScript. Below is the code for my table: <table> <tr> <td id="content_heading" width="25px">ID</td> <td id="content_heading" width="150px">Last Name</td> <td id="content_heading" width="150px">First Name</td> <td id="content_heading" width="75px">SSN</td> </tr> <?php $user = 'user'; $pass = 'pass'; $server = 'localhost'; $link = mysql_connect($server, $user, $pass); if (!$link){ die('Could not connect to database!' . mysql_error()); } mysql_select_db('mydb', $link); $query = "SELECT * FROM employees"; $result = mysql_query($query); mysql_close($link); $num = mysql_num_rows($result); for ($i = 0; $i < $num; $i++){ $row = mysql_fetch_array($result); $class = (($i % 2) == 0) ? "table_odd_row" : "table_even_row"; echo "<tr class=".$class.">"; echo "<td>".$row[id]."</td>"; echo "<td>".$row[l_name]."</td>"; echo "<td>".$row[f_name]."</td>"; echo "<td>".$row[ssn]."</td>"; echo "</tr>"; } ?> </table>

  • Div smart width

    - by Mark
    see fiddle html <div class="e" style="left:5px;top:5px;">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa bbbbbbbbbbbbbbbbbbbbbbbbbb</div> <div class="e" style="left:5px;top:100px;">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</div>? css .e { font-size: 10px; font-family: arial; background-color: yellow; position: absolute; max-width: 300px; } you will notice the 2nd div fits the size of the content exactly, but on the first div there's a bunch of empty space to the right of the a's and b's. This is because the div hit its max width of 300px and then wrapped the b's to a 2nd line. The wrapping is good, but then I would expect the div to then shrink back down to the width of the a's so that there's no empty space to the right. Is it possible to get it to do this? Tested in Chrome and FF.

  • Call a non member funcion on an instance before is constructed.

    - by Tom
    Hi everyone. I'm writing a class, and this doubt came up. Is this undef. behaviour? On the other hand, I'm not sure its recommended, or if its a good practice. Is it one if I ensure no exceptions to be thrown in the init function? //c.h class C{ float vx,vy; friend void init(C& c); public: C(); ~C(); }; //c.cpp C::C() { init(*this); } void init(C& c) //throws() to ensure no exceptions ? { c.vx = 0; c.vy = 0; } Thanks in advance

  • doctrine default values and relations

    - by Skirmantas
    Concept: Lets say we have table Properties with columns id and name (lets say with some predefined values: "Good" "Better" "Best"). Another table Users has column property_id with many to one relation on Properties (property_id = id). Users has default value on property_id, lets say 1 which means "Good". We might have another table analogue to Users however with default property, lets say "Better". What I need is ability to change default value for Users or other tables in administrator's panel. In mysql I can set default value for column like this: ALTER TABLE <Table> CHANGE <Column> DEFAULT <NEW_DEFAULT_VALUE> I can retrieve default value: SELECT DEFAULT(<Column>) FROM <Table> LIMIT 1 Is it possible to achieve this concept with Doctrine? What I actually need is such method in my table class: class UserTable extend Doctrine_Table { /* ... */ getDefaultProperty() { } setDefaultProperty($value) { /* $value can be either integer or Doctrine_Record */ } }

  • AppEngine: Can I write a Dynamic property (db.Expando) with a name chosen at runtime?

    - by MarcoB
    If I have an entity derived from db.Expando I can write Dynamic property by just assigning a value to a new property, e.g. "y" in this example: class MyEntity(db.Expando): x = db.IntegerProperty() my_entity = MyEntity(x=1) my_entity.y = 2 But suppose I have the name of the dynamic property in a variable... how can I (1) read and write to it, and (2) check if the Dynamic variable exists in the entity's instance? e.g. class MyEntity(db.Expando): x = db.IntegerProperty() my_entity = MyEntity(x=1) # choose a var name: var_name = "z" # assign a value to the Dynamic variable whose name is in var_name: my_entity.property_by_name[var_name] = 2 # also, check if such a property esists if my_entity.property_exists(var_name): # read the value of the Dynamic property whose name is in var_name print my_entity.property_by_name[var_name] Thanks...

  • Sources from referenced projects are not deployed to Tomcat in Eclipse

    - by Steven De Groote
    Hi, I have setup a dynamic web project in eclipse with JSF in which I trust on code from another project (framework). Therefore, I added the framework project to the build path of the website project. So far so good, Eclipse recognises every class and the project builds without errors. Problem is though that when I do "run on server" to test it on tomcat 6.0.24, the application fails. I get ClassNotFoundException on every class from the framework project. Is this a bug or is some specific configuration necessary for this?

  • Several modules in a package importing one common module

    - by morpheous
    I am writing a python package. I am using the concept of plugins - where each plugin is a specialization of a Worker class. Each plugin is written as a module (script?) and spawned in a separate process. Because of the base commonality between the plugins (e.g. all extend a base class 'Worker'), The plugin module generally looks like this: import commonfuncs def do_work(data): # do customised work for the plugin print 'child1 does work with %s' % data In C/C++, we have include guards, which prevent a header from being included more than once. Do I need something like that in Python, and if yes, how may I make sure that commonfuncs is not 'included' more than once?

    - by Projapati
    I have a Terms and Condition checkbox on my signup page. I want to make it required like my few other fields on the form before posting to server. This validation must be done at client side. Anyone knows how to do it properly?

That way I can easily use jquery to do validation and then submit? Thanks for reading

  • jUnit same exception in different cases

    - by coubeatczech
    Hi, I'm writing a jUnit test for a constructor that parses a String and then check numerous things. When there's wrong data, for every thing, some IllegalArgumentException with different message is thrown. So I would like to write tests for it, but how can i recognize what error was thrown? This is how can I do it: @Test(expected=IllegalArgumentException.class) public void testRodneCisloRok(){ new RodneCislo("891415",dopocitej("891415")); } and this is how I would like to be, but I don't know if it is possible to write it somehow: @Test(expected=IllegalArgumentException.class("error1")) public void testRodneCisloRok(){ new RodneCislo("891415",dopocitej("891415")); }

  • JQuery within a partial view not being called

    - by XN16
    I have a view that has some jQuery to load a partial view (via a button click) into a div in the view. This works without a problem. However within the partial view I have a very similar bit of jQuery that will load another partial view into a div in the first partial view, but this isn't working, it almost seems like the jQuery in the first partial view isn't being loaded. I have tried searching for solutions, but I haven't managed to find an answer. I have also re-created the jQuery function in a @Ajax.ActionLink which works fine, however I am trying to avoid the Microsoft helpers as I am trying to learn jQuery. Here is the first partial view which contains the jQuery that doesn't seem to work, it also contains the @Ajax.ActionLink that does work: @model MyProject.ViewModels.AddressIndexViewModel <script> $(".viewContacts").click(function () { $.ajax({ url: '@Url.Action("CustomerAddressContacts", "Customer")', type: 'POST', data: { addressID: $(this).attr('data-addressid') }, cache: false, success: function (result) { $("#customerAddressContactsPartial-" + $(this).attr('data-addressid')) .html(result); }, error: function () { alert("error"); } }); return false; }); </script> <table class="customers" style="width: 100%"> <tr> <th style="width: 25%"> Name </th> <th style="width: 25%"> Actions </th> </tr> </table> @foreach (Address item in Model.Addresses) { <table style="width: 100%; border-top: none"> <tr id="[email protected]"> <td style="width: 25%; border-top: none"> @Html.DisplayFor(modelItem => item.Name) </td> <td style="width: 25%; border-top: none"> <a href="#" class="viewContacts standardbutton" data-addressid="@item.AddressID">ContactsJQ</a> @Ajax.ActionLink("Contacts", "CustomerAddressContacts", "Customer", new { addressID = item.AddressID }, new AjaxOptions { UpdateTargetId = "customerAddressContactsPartial-" + @item.AddressID, HttpMethod = "POST" }, new { @class = "standardbutton"}) </td> </tr> </table> <div id="[email protected]"></div> } If someone could explain what I am doing wrong here and how to fix it then I would be very grateful. Thanks very much.

  • Is MSDN referencing a system.thread, a worker thread, an io thread or all three?

    - by w0051977
    Please see the warning below taken from the StreamWriter class specification (http://msdn.microsoft.com/en-us/library/system.io.streamwriter.aspx): "Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe." I understand that a W3WC process contains two thread pools i.e. worker threads and I/O threads. A worker thread could contain many threads of its own (if the application creates its own System.Thread instances). Does the warning only relate to System.Threads or does it relate to worker threads and I/O threads as well I.e. as the instance variables of the streamwriter class are not thread safe then does this mean that there would be problems if multiple worker threads access it eg if two users on two different web clients attempt to write to the log file at the same time, then could one lock out the other?

  • Is it possible to use AutoMapper to map methods?

    - by Woj
    I have two classes: public class TestClass1 { public int TestInt { get; set; } public void TestMethod() { // Do something } } public class TestClass2 { public int TestInt { get; set; } public void TestMethod() { // Do something } } I want to create interface that I can use for both classes. The easiest solution is to implement the interface on TestClass1 and TestClass2 but I don;t have access to the implementation of these classes (external dll). I was wondering if I can create new interface and use AutoMapper to map TestClass1 and TestClass2 to ITestInterface: public interface ITestInterface { int TestInt { get; set; } void TestMethod(); }

But it will only work with 2 levels deep, what I need it to do is work with unlimited levels.

Has anyone run across this?
