  • Find the right parameters for an event without using Design Mode in Visual Studio 2010

    - by Jason
    Is there a way to know what parameters are needed by an event in Visual Studio 2010? Let's say I have a DropDownList control and I want to bind a method to the "OnSelectedIndexChanged", I would do something like this In the ASPX File: <asp:DropDownList ID="lstMyList" runat="server" OnSelectedIndexChanged="lstMyList_SelectedIndexChanged"></asp:DropDownList> In the codebehind: protected void lstMyList_SelectedIndexChanged(object sender, EventArgs e) { ... } Is there a way to know what parameters the method needs? (In this case, an object for the sender and an EventArgs parameter for the event.) I know you can easily create the method by double-clicking the right event in Design Mode, but it does a mess with your code so I prefer not to use it. Thanks!

  • When to use CreateChildControls() vs. embedding in the ASPX

    - by Kelly French
    I'm developing a webpart for SharePoint 2007 and have seen several posts that advise to do all the creation of controls in the code-behind. I'm transitioning from Java J2EE development so I don't have the platform history of .Net/ASP/etc. In other places it shows how you can do the same thing by embedding the control definition into the asp page with tags My question is this: What is the rule governing where to implement controls? Has this rule changed recently, ASP vs ASP.Net or ASP.Net MVC maybe? Is this advice limited to SharePoint development?

  • Tool used to retrieve code metrics in xUnit Test Patterns?

    - by leeand00
    I'm reading xUnit Test Patterns by Gerard Meszaros. On one of the pages he refers to some software metrics: While the need to wrap lines to keep them at 65 characters makes this code look even longer than it really is, it is still unnecessarily long. It contains 25 executable statements including initialized declarations, 6 lines of control statements, 4 in-line comments, and 2 lines to declare the test method—giving a total of 37 lines of unwrapped source code. Short of counting the statements to find these metrics, does anybody have any idea if he used a particular tool to calculate the metrics? (If you have any suggestions for tools that will count similar metrics, I'm looking for one that works on Java, Javascript and C++) Thanks!

  • Regular expression to remove all text except...

    - by Barryman9000
    There may be an easier way, and if there is I'm all for it. However - my ASP.NET page has a TON of controls on it, and I've given them all ID's that start with underscore. I copied all the markup into Notepad++ and I'm trying to find a regular expression that will find everything but the controls and replace it with whitespace. that way I'll have a text file that has all my control names which I'll probably throw into Excel and do some string manipulation to add ".Text = " etc. Any suggestions?

  • Adding Silverlight pages to existing ASP.net page??

    - by AJ
    Hi I know how to add SL page as a whole to existing ASP.net application. We have existing ASP.net page with few tabs. Each tab is a user control. We want to add another tab, which will host Silverlight content. Is it possible to add silverlight content in one of the tabs of a page? Any example links? Another way of putting up the same question : Is it possible to have an ASP.net page with top half as regular asp.net content and other half containing silverlight content? Please advise. Thanks AJ

  • ASP.NET (AJAX) UI Design Tools for Artistically Challenged?

    - by davemackey
    I'm building an application but I'm artistically challenged and I'd rather not spend my time writing widgets (e.g. ability to collapse/expand/close/drag-drop) if there is already controls available. I've worked with the Microsoft AJAX Control Toolkit - but these tools still require a lot of work to get a working widget (which in my case, won't look too pretty). The CollapsiblePanel is pretty nice - but then you have to program in the minimize button, close button, maximize button, etc. Looking for suggestions that will help me design better UI faster...

  • Can't get ScrollTo to work with keyboard arrows

    - by adamwstl
    I'm trying to setup the Jquery plugin SerialScroll with Ariel's added keyboard controls. I'm calling these three JS files: serialScroll.js scrollTo.js keyboard.js (the keyboard control snippet) Html I'm trying to manipulate. Want it to jump from ind-photo to ind-photo on arrow left and right. <div id="photos"> <div class="ind-photo"><img src="2.jpg" /></div> <div class="ind-photo"><img src="3.jpg" /></div> </div> I can't get it to work at all. I know there are likely slight things that are going to be off, but this isn't working at all. Thanks in advance.

  • jQuery class adding and removing with click and mouseleave

    - by danixd
    I just want to control a div by toggling a class on click, as well as removing it when the mouse leaves the div. I had it working with mouseout, but when I entered over a child element, the mouseOut triggered, so I know I need to use mouseleave. I am just unsure how incorporate telling jQuery the mouse has entered. Yes I am new to this! Here is my code: $(function(){ $('.main').click(function() { $(this).toggleClass('activated'); }); }); $(function(){ $('.main').mouseleave(function() { $(this).removeClass('activated'); }); });

  • YAGNI and database creation scripts

    - by Daniel Straight
    Right now, I have code which creates the database (just a few CREATE queries on a SQLite database) in my main database access class. This seems unnecessary as I have no intention of ever using the code. I would just need it if something went wrong and I needed to recreate the database. Should I... Leave things as they are, even though the database creation code is about a quarter of my file size. Move the database-creation code to a separate script. It's likely I'll be running it manually if I ever need to run it again anyway, and that would put it out-of-sight-out-of-mind while working on the main code. Delete the database-creation code and rely on revision control if I ever find myself needing it again.

  • DLL response is to slow in Visual Studio

    - by magsto
    Hi, I use a 3rd party DLL in my VB.NET project (VS2005) that responds to slow and give wrong values in debug mode. In run-time mode everything works as expected. I do understand that there are something going on in the debug mode which makes the DLL communication slow. This behavior makes it hard to debug the application correctly. Is there any way to force VS to communicate with the DLL in "run-time" mode during debugging but let the rest of the project be in control of the debugger?

  • Retrieving data from facebook in a winform

    - by gillyb
    Hey, I understand that using the facebook API I need an api key to connect, but I still don't understand how i would go about doing this, and how can i retrieve information upon users using the API (i'm only interested in retrieving the information that is publicly available e.g: username, birthdate, and other info that a specific user left public) I downloaded the facebook development kit, and tried adding the FacebookService control, but i don't get it... All the examples/samples i found on the internet are older than the version i have and therefore work a little different.. Can someone please post an example of how i would connect, using a certain API key, and retrieve someones public info/public photos (if there are any) ?? Thanks. :)

  • How to limit number of displayed items in html.dropdownlist?

    - by Remnant
    I have a html.dropdownlist on my webpage as follows: <%=Html.DropDownList("MyDropDown", Model.Data, new { @class = "dropdown"})%> I am populating the dropdown with ~80 items. The issue is that when I click the dropdown the list of items is rendered from the top of the screen to the bottom of the screen. How can I set up the dropdownlist so that it only displays a maximum of 20 items when the dropdown menu is clicked (i.e. user needs to scroll down to see items 21 - 80)? I was anticipating (!) that there would be a html.dropdownlist property to control the number of displayed items that would allow something like the following e.g.: <% =Html.DropDownList("MyDropDown", Model.Data, new { @class = "dropdown", rows ="20"}) %> From research I have been doing on the msdn website it appears that there is no such property and that each browser has its own rules of how many items are displayed in a dropdownlist (?). I am using IE6 and IE7.

  • Maven: add a dependency to a jar by relative path

    - by flybywire
    I have a proprietary jar that I want to add to my pom as a dependency. But I don't want to add it to a repository. The reason is that I want my usual maven commands such as mvn compile, etc, to work out of the box. (Without demanding from the developers a to add it to some repository by themselves). I want the jar to be in a 3rdparty lib in source control, and link to it by relative path from the pom.xml file. Can this be done? How?

  • some OVERLAPS using WSASend not returning in a timely manner using GetQueuedCompletionStatus?

    - by Geoffrey
    Background: I'm using CreateIoCompletionPort, WSASend/Recv, and GetQueuedCompletionStatus to do overlapped socket io on my server. For flow control, when sending to the client, I only allow several WSASend() to be called when all pending OVERLAPs have popped off the IOCP. Problem: Recently, there are occassions when the OVERLAPs do not get returned to the IOCP. The thread calling GetQueuedCompletionStatus does not get them and they remain in my local pending queue. I've verified that the client DOES receive the data off the socket and the socket is connected. No errors were returned when the WSASend() calls were made. The OVERLAPs simply "never" come back without an external stimulus like the following: Disconnecting the socket from the client or server, immediately allows the GetQueuedCompletionStatus thread to retrieve the OVERLAPs Making additional calls to WSASend(), sometimes several are needed, before all the OVERLAPs suddenly pop off the queue. Question: Has anyone seen this type of behavior? Any ideas on what is causing this? Thanks, Geoffrey

  • Memory leak when declaring NSString from ABRecordCopyValue

    - by Ben Thompson
    I am using the following line of code... NSString *clientFirstName = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty); The 'analyse' feature on Xcode is saying that this giving rise to a potential memory leak. I am not releasing clientFirstName at all as I have neither alloc or retain'd it. However, I am conscious that ABRecordCopyValue may not be returning an object as say a command like [NSMutableArray arrayWithArray:someArray] would which might mean I am indeed creating a new object that I control and must release. Keen to hear thoughts...

  • Remove a toolbar when pushing a new view

    - by nevan
    In the iPhone maps app there's a toolbar at the bottom of the map view (it contains the Search/Directions segment control and others). When moving from the map view by clicking on a callout, the toolbar slides out with the map view, leaving the next view (a table controller) with no toolbar. I've tried to do the same thing with [self.navigationController setToolbarHidden:YES animated:YES] in the second view controller, but this gives a strange toolbar sliding down animation, while the map view is sliding to the left. Using [self.navigationController setToolbarHidden:YES] in viewDidLoad:animated also causes a bad effect (it makes the toolbar disappear the moment the push animation starts, leaving an ugly white space). I'm assuming the answer to this is to use a nib file, but I'd prefer to do it programatically (if possible). How can I get the toolbar to "stick" to the map view and slide out with it when I push a new view controller? Thanks.

  • window.onbeforeunload ajax request problem with Chrome

    - by lang2
    Hello, I have a web page that handles remote control of a machine through Ajax. When user navigate away from the page, I'd like to automatically disconnect from the machine. So here is the code: window.onbeforeunload = function () { bas_disconnect_only(); } The disconnection function simply send a HTTP GET request to a PHP server side script, which does the actual work of disconnecting: function bas_disconnect_only() { var xhr = bas_send_request("req=10", function() { } ); } This works fine in FireFox. But with Chrome, the ajax request is not sent at all. There is a unacceptable workaround: adding alert to the callback function: function bas_disconnect_only() { var xhr = bas_send_request("req=10", function() { alert("You're been automatically disconnected."); } ); } After adding the alert call, the request would be sent successfully. But as you can see, it's not really a work around at all. Could somebody tell me if this is achievable with Chrome? What I'm doing looks completely legit to me. Thanks,

  • How to stop the execution of Java program from Command line?

    - by Aakash
    My main field is .Net but recently I have got something to do with Java. I have to create a shell utility in Java that could run in background reading few database records after specified duration and do further processing. It's a kind of scheduler. Now I have few concerns: How to make this work as a service. I want to execute it through a shell script and the utility should start running. Off course the control should get back to the calling script. Secondly, eventually i may want to stop this process from running. How to achieve this? I understand these are basic question but I really have no idea where to begin and what options are best for me. Any help / advise please?

  • How to Promote iPhone App

    - by Ricibald
    I published my app. I request a review to more than 150 sites but only 8 of them give me a (good) review. I can't reach the most famous blogs because I have to pay to bring on top of their queue. Now, my app seems to be nice but I have only 65 users playing it. This 65 users seems to really like it because I can see there are a lot of games played tracked in my stats. A lot of users say that my app is "fun like Doodle Jump and very addictive". So, what's the problem? Why only 65 people? In a word, how can simple games such "Doodle Jump" or "Flight Control" enter in top 10? What's their secret? What's my mistake? UPDATE: I have a site describing my app.

  • Code generating SOAP Web Service Proxy objects yourself - C#/.NET 3.5/T4

    - by tyndall
    Is there a framework or code already available that will give me more control over the code that gets generated based off my web references? I'm working at a new company. And the Web Services Proxies are all self contained in their own assembly. I would really rather generate this whole project. Every time they change something on the Services-side (Java) the WSDL references have to be dropped and re-added. (I can't figure out what those guys are doing on their end that messes with the WSDL bad enough that this needs to be done so much) Their are 10 of these references. I'd rather codegen the whole thing at compile time. Every time. What are my options?

  • ComboBox SelectedItem vs SelectedValue

    - by Anna Lear
    The following code works as you’d expect — MyProperty on the model is updated when the user picks a new item in the dropdown. comboBox1.DataBindings.Add("SelectedValue", myModel, "MyProperty", true, DataSourceUpdateMode.OnPropertyChanged); The following, however, doesn’t work the same way and the model update isn’t triggered until the input focus moves to another control on the form: comboBox1.DataBindings.Add("SelectedItem", myModel, "MyProperty", true, DataSourceUpdateMode.OnPropertyChanged); Does anybody know why? I don’t even know where to start investigating the cause. Pointers in the right direction to start the investigation or an outright explanation would be equally appreciated. Thanks.

  • Finding an HTTP proxy that will intercept static resource requests

    - by pkh
    Background I develop a web application that lives on an embedded device. In order to make dev times sane, frontend development is done using apache serving static documents, with PHP proxying out to the embedded device for specifically configured dynamic resources. This requires that we keep various server-simulation scripts hanging around in source control, and it requires updating those scripts whenever we add a new dynamic resource. Problem I'd like to invert the logic: if the requested document is available in the static documents directory, serve it; otherwise, proxy the request to the embedded device. Optimally, I want a software package that will do this for me (for Windows or buildable on cygwin). I can deal with forcing apache to do it with PHP, but I'm unsure how to configure it to make it happen. I've looked at squid and privoxy, but neither of them seem to do what I want. Any ideas? I'd rather not have to roll my own.
