    - by Alex
    Does Zend application server provide any sort of pushed-based messaging architecture support?I mean some different message-oriented middlewares that can be used for the push-based architecture or email support?There is a need in provision of the non web-based interface for certain users of the website who would get regular messages notifying them of different special offers in their field of interest(it should be push-based)

  • How to set JComboBox not to select an element when created? (Java)

    - by Alex Cheng
    Hi all. Problem: I am using JComboBox, and tried using setSelectionIndex(-1) in my code (this code is placed in caretInvoke()) suggestionComboBox.removeAllItems(); for (int i = 0; i < suggestions.length; i++) { suggestionComboBox.addItem(suggestions[i]); } suggestionComboBox.setSelectedIndex(-1); suggestionComboBox.setEnabled(true); This is the initial setting when it was added to a pane: suggestionComboBox = new JComboBox(); suggestionComboBox.setEditable(false); suggestionComboBox.setPreferredSize(new Dimension(25, 25)); suggestionComboBox.addActionListener(new SuggestionComboBoxListener()); When the caretInvoke triggers the ComboBox initialisation, even before the user selects an element, the actionPerformed is already triggered (I tried a JOptionPane here): First popup (notice that "flow byte_jump" is selected): Second popup (I think the setSelectionIndex is executed) Then in the end: The problem is: My program autoinserts the selected text when the user selects an element from the ComboBox. So without the user selecting anything, it is automatically inserted already. How can I overcome the problem in this situation? Thanks.

  • Why do I need to give my options a value attribute in my dropdown? JQuery.

    - by Alex
    So far in my web developing experiences, I've noticed that almost all web developers/designers choose to give their options in a select a value like so: <select name="foo"> <option value="bar">BarCheese</option> // etc. // etc. </select> Is this because it is best practice to do so? I ask this because I have done a lot of work with jQuery and dropdown's lately, and sometimes I get really annoyed when I have to check something like: $('select[name=foo]').val() == "bar"); To me, many times that seems less clear than just being able to check the val() against BarCheese. So why is it that most web developers/designers specify a value paramater instead of just letting the options actual value be its value?

PS: parameter names are equal within a list.

  • What's the difference between single and double quotes in Objective-C?

    - by Alex Mcp
    I'm working through a book exercise to generate some random serial number, and here's my function: NSString *randomSerialNumber = [NSString stringWithFormat:@"%c%c%c%c%c", '0' + random() % 10, 'A' + random() % 26, '0' + random() % 10, 'A' + random() % 26, '0' + random() % 10]; This works and has an output like: 2J6X7. But before, the 0s and As I had wrapped in double quotes, and an example output was 11764iÒ˜. What did I do wrong my first time around, and why did using single quotes fix it?

  • Developers portfolios

    - by Alex
    I'm wondering if you have one, or u know any developer/programmer online portofolio. I know many web developers have one (and in many cases very well designed), but not any C++ developer (for example). On the net there are only some good blogs about some programming language, but in many cases these are extremely poor from a design point of view and i'd say very "nerdy".

  • How do I refer to a windows form control by name (C# / VB)

    - by Alex
    Suppose I have a label control on a windows form called "UserName". How can I refer to that label programmatically using the label name? For example I can do: For each ctrl as Control in TabPage.Controls If ctrl.Name = "UserName" Then ' Do something End If Next This seems quite inefficient. I would like to do something like: TabPage.Controls("UserName").Text = "Something" I did some googling but couldn't find a satisfactory answer. Most suggested looping, some said .NET 2005 doesn't support direct refenece using string name, and FindControl method was asp.net only... EDIT Thanks for the response so far. Here is a bit more detail. I have a windows form with three tabpages, all of which a very similar in design and function i.e. same drop down menus, labels, react in simlar way to events etc. Rather than write code for each event per tabpage I have built a class that controls the events etc. per tabpage. For example, on each tabpage there is a Label called "RecordCounter" that simply shows the number of rows in the datagridview when it is populated by selection of a variable in a drop down menu. So what I want to be able to do is, upon selection of a variable in the drop down menu, the datagridview populates itself with data, and then I simply want to display the number of rows in a label ("RecordCounter"). This is exactly the same process on each tabpage so what I am doing is passing the tabpage to the class and then I want to be able to refer to the "RecordCounter" and then update it. In my class I set the ActivePage property to be the TabPage that the user has selected and then want to be able to do something like: ActivePage.RecordCounter.Text = GetNumberOfRows()

  • How to implement dual communication between server and client via http

    - by Alex Sebastiano
    I have a AJAX client which must receive messages from server. Some messages from server not like request-response type. For example, imaging game in which players can enter. Server must send to client info about player entering. But how can server send message to client via http without request from client? Only decision that i can invent: client send request to server (getNewPlayerEnter request) with big timeout, server checks state of player set, if in set new players are, then server send info to client, if not server 'sleeps' on some time, and after 'sleeping' server checks players set again. I think my desicion a little stupid(maybe not little). How implement it right? p.s. sorry for my english

  • How can I collapse a dataframe by some variables, taking mean across others

    - by Alex Holcombe
    I need to summarize a data frame by some variables, ignoring the others. This is sometimes referred to as collapsing. E.g. if I have a dataframe like this: Widget Type Energy egg 1 20 egg 2 30 jap 3 50 jap 1 60 Then collapsing by Widget, with Energy the dependent variable, Energy~Widget, would yield Widget Energy egg 25 jap 55 In Excel the closest functionality might be "Pivot tables" and I've worked out how to do it in python (http://alexholcombe.wordpress.com/2009/01/26/summarizing-data-by-combinations-of-variables-with-python/), and here's an example with R using doBy library to do something very related (http://www.mail-archive.com/[email protected]/msg02643.html), but is there an easy way to do the above? And even better is there anything built into the ggplot2 library to create plots that collapse across some variables?

  • Step by Step validation with jquery validation plugin

    - by Alex
    I know its been asked many times already but no one could come up with solution so far. The idea is to have one form separated into few steps and validate each step on next click of the button. I know jquery validation plugin is offering quite complicated way of doing it with accordion but can anyone come up with a simple solution something like var stepOne = { rules: { fieldname1: "required", fieldname2: "required", } } $("form").validate(stepOne); //onclick hope someone could suggest the best way of doing it. Thanks.

  • How can I get an Active Directory data code from System.DirectoryServices[.Protocols]?

    - by Alex Waddell
    When using .Protocols, I can run the following pseudocode to authenticate to an AD: try { LdapConnection c = new LdapConnection("User", "Password"); c.Bind(); } catch (LdapException le) { Debug.WriteLine(le.ResultCode); } This code will allow me to get the "Invalid Credentials" error string, and the AD code "49", but I need to get the additional data errors similar to an LDAP Java client : [LDAP: error code 49 - 80090308: LdapErr: DSID-0C09030F, comment: AcceptSecurityContext error, data **525**, vece ] 525 – user not found 52e – invalid credentials (bad password) 530 – logon time restriction 532 – password expired 533 – account disabled 701 – account expired 773 – user must reset password

  • What's the new way to iterate over a Java Map in Scala 2.8.0?

    - by Alex R
    How does scala.collection.JavaConversions supercede the answers given here: http://stackoverflow.com/questions/495741/iterating-over-java-collections-in-scala (doesn't work because the "jcl" package is gone) and here http://www.eishay.com/2009/05/iterating-over-map-with-scala.html (doesn't work me in a complicated test which I'll try to boil down and post here later) The latter is actually a Scala Map question but I think I need to know both answers in order to iterate over a java.util.Map. Thanks

  • How do travel search engines & aggregators get their source data?

    - by Alex
    I'm tossing around a few ideas for travel search engines and I'm wondering how these sites get their source data. Do they scrape all the content from airline homepages? This seems like an enormous job given the number of airlines etc out there. Is there some API or web service standard that every airline conforms too? Am I going to have to negotiate access to the data APIs for every airline I wish to index?

  • Jquery Var Returned As object

    - by alex
    I'm trying to pass a variable from one function to another, but the var elmId is being returned as an object and giving an error. When we click on any of the generated divs we should be able to change the size of the div by choosing a width / height value from the drop down menus. I'm trying to pass the clicked div id which is elmId to function displayVals but it is not working. If we replace "#"+elmId in the function displayVals with the actual id of the first div created with is "#divid1" then it works. Why is the value of var elmId not being passed to displayVals <link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.7/themes/base/jquery-ui.css" type="text/css" media="all" /> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" type="text/javascript"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.7/jquery-ui.min.js" type="text/javascript"></script> <style> .aaa{width:100px; height:100px; background-color:#ccc;} button{width:100px; height:20px;} </style> <button class="idiv">div</button> <select id="width"> <option>100px</option> <option>200px</option> <option>300px</option> </select> <select id="height"> <option>100px</option> <option>200px</option> <option>300px</option> </select> <p></p> <script type="text/javascript"> var divId = 1; $("button").click(function(){ var elm = $('<div id=divid' + divId + ' class=aaa></div>'); elm.appendTo('p'); divId++; }); $("p").click(function(e){ var elmType = $(e.target)[0].nodeName, elmId = $(e.target)[0].id; return displayVals(elmId); }); function displayVals(elmId) { var iwidth = $("#width").val(); var iheight = $("#height").val(); $("#"+elmId).css({width:iwidth, height:iheight}); console.log(elmId); } $("select").change(displayVals); displayVals(); </script>

  • .net mvc2 custom HtmlHelper extension unit testing

    - by alex
    My goal is to be able to unit test some custom HtmlHelper extensions - which use RenderPartial internally. http://ox.no/posts/mocking-htmlhelper-in-asp-net-mvc-2-and-3-using-moq I've tried using the method above to mock the HtmlHelper. However, I'm running into Null value exceptions. "Parameter name: view" Anyone have any idea?? Thanks. Below are the ideas of the code: [TestMethod] public void TestMethod1() { var helper = CreateHtmlHelper(new ViewDataDictionary()); helper.RenderPartial("Test"); // supposingly this line is within a method to be tested Assert.AreEqual("test", helper.ViewContext.Writer.ToString()); } public static HtmlHelper CreateHtmlHelper(ViewDataDictionary vd) { Mock<ViewContext> mockViewContext = new Mock<ViewContext>( new ControllerContext( new Mock<HttpContextBase>().Object, new RouteData(), new Mock<ControllerBase>().Object), new Mock<IView>().Object, vd, new TempDataDictionary(), new StringWriter()); var mockViewDataContainer = new Mock<IViewDataContainer>(); mockViewDataContainer.Setup(v => v.ViewData) .Returns(vd); return new HtmlHelper(mockViewContext.Object, mockViewDataContainer.Object); }

  • How to create a step by step wizard in C++ (with unmanaged code) in Visual Studio 2010

    - by Alex. S.
    I would like to build a small wizard in C++ with no dependencies on any framework. Apparently, is really simple, but I don't know where to start. Can you point me to good information (tutorials, etc) on it. Should I use MFC Application or a Win32 project? Is there any step by step guide ? I'm using VS 2010. The majority of info I'd found on MFC is really old. It seems like the vast majority of development is going .net.

Is an ArrayList as an instance variable automatically declared static?
