  • HTML5 localStorage restrictions and limits

    - by Chuck
    HTML5's localStorage databases are usually size-limited — standard sizes are 5 or 10 MB per domain. Can these limits be circumvented by subdomains (e.g. example.com, hack1.example.com and hack2.example.com all have their own 5 MB databases)? And is there anything in the standard that specifies whether parent domains can access their children's databases? I can't find anything, and I can see arguments for doing it either way, but it seems like there has to be some standard model.

  • DateTimePicker automatically move to next datepart

    - by Leon Tayson
    Currently, when using the datetimepicker, after you enter the month you have to either hit the right arrow or the "/" for it to move to the day. Is there a property that I can set or a way to know that the month is done and move to the day and move to the year after the user is done with the day? This is the same behavior with applications written in the old FoxPro/Clipper days.

  • Throttling an AMQP Consumer Using RabbitMQ

    - by Nicholas
    I'm using AMQP in a reliability pattern and my use-case is to put messages in a queue, then consume them and insert the information into a web service. My web service is slow, and my queue can have many, many messages and I would like to ensure that the consumer doesn't kill my database. Is there a build-in way to perform throttling in RabbitMQ, either time-based(only X messages per minute/second/hour) or some other mechanism?

  • Detecting when error image in PictureBox is used

    - by DMan
    I found this on Google, click here, which someone asked a similar question, receiving a response that they should check if their file exists. However, I'm loading images from web links, in which it displays an error image if A)The picture is not found or B)If, like in image hosting services like Photobucket, displays the 'Bandwidth exceeded' image. Is there a way to detect if either an error image is showing or if a image is invalid?

  • Linq 2 Sql DateTime format to string yyyy-MM-dd

    - by Bogdan Maxim
    Basically, i need the equivalent of T-SQL CONVERT(NVARCHAR(10), datevalue, 126) I've tried: from t in ctx.table select t.Date.ToString("yyyy-MM-dd") but it throws not supported exception from t in ctx.table select "" + t.Date.Year + "-" + t.Date.Month + "-" + t.Date.Day but i don't think it's an usable solution, because i might need to be able to change the format. The only option I see is to use Convert.ToString(t.Date, FormatProvider), but i need a format provider, and I'm not sure it works either.

  • Windows Service Installation Problem

    - by user221919
    hi When I start to installing using installutil it gives me following error, I have set ServiceInstaller and ServiceInstallerProcess System.InvalidOperationException: Installation failed due to the absence of a ServiceProcessInstaller. The ServiceProcessInstaller must either be the containing installer, or it must be present in the Installers collection on the same installer as the ServiceInstaller. Waiting for your valuable thoughts. Thanking You

  • Hadoop Hive web interface options

    - by Garethr
    I've been experimenting with Hive for some data mining activities and would like to make it easily available to less command line orientated colleagues. Hive does now ship with a web interface (http://wiki.apache.org/hadoop/Hive/HiveWebInterface) but it's very basic at this stage. My question is does a visually polished and fully featured interface (either desktop or preferably web based) to Hive exist yet? Are their any open source efforts outside the Hive project working on this?

  • Capture SOAP Envelope (C# WinForm calling .ASMX external vendor service)

    - by NealWalters
    I'm calling a third-party vendor's external SSL web service from a .NET 3.5 client (WinForm). The vendor has asked me to send them the Soap Header to verify why things aren't working. I used WireShark to capture packets, but since the web service is SSL, the packets are encrypted. Is there a few magic lines of code to add to my C# client to save or display the Soap Envelope either right before I call their web/method or right after?

  • ASP.NET MVC2: Getting textbox data from a view to a controller

    - by mr_plumley
    Hi, I'm having difficulty getting data from a textbox into a Controller. I've read about a few ways to accomplish this in Sanderson's book, Pro ASP.NET MVC Framework, but haven't had any success. Also, I've ran across a few similiar questions online, but haven't had any success there either. Seems like I'm missing something rather fundamental. Currently, I'm trying to use the action method parameters approach. Can someone point out where I'm going wrong or provide a simple example? Thanks in advance! Using Visual Studio 2008, ASP.NET MVC2 and C#: What I would like to do is take the data entered in the "Investigator" textbox and use it to filter investigators in the controller. I plan on doing this in the List method (which is already functional), however, I'm using the SearchResults method for debugging. Here's the textbox code from my view, SearchDetails: <h2>Search Details</h2> <% using (Html.BeginForm()) { %> <fieldset> <%= Html.ValidationSummary() %> <h4>Investigator</h4> <p> <%=Html.TextBox("Investigator")%> <%= Html.ActionLink("Search", "SearchResults")%> </p> </fieldset> <% } %> Here is the code from my controller, InvestigatorsController: private IInvestigatorsRepository investigatorsRepository; public InvestigatorsController(IInvestigatorsRepository investigatorsRepository) { //IoC: this.investigatorsRepository = investigatorsRepository; } public ActionResult List() { return View(investigatorsRepository.Investigators.ToList()); } public ActionResult SearchDetails() { return View(); } public ActionResult SearchResults(SearchCriteria search) { string test = search.Investigator; return View(); } I have an Investigator class: [Table(Name = "INVESTIGATOR")] public class Investigator { [Column(IsPrimaryKey = true, IsDbGenerated = false, AutoSync=AutoSync.OnInsert)] public string INVESTID { get; set; } [Column] public string INVEST_FNAME { get; set; } [Column] public string INVEST_MNAME { get; set; } [Column] public string INVEST_LNAME { get; set; } } and created a SearchCriteria class to see if I could get MVC to push the search criteria data to it and grab it in the controller: public class SearchCriteria { public string Investigator { get; set; } } } I'm not sure if project layout has anything to do with this either, but I'm using the 3 project approach suggested by Sanderson: DomainModel, Tests, and WebUI. The Investigator and SearcCriteria classes are in the DomainModel project and the other items mentioned here are in the WebUI project. Thanks again for any hints, tips, or simple examples! Mike

  • Masked Time control in WPF

    - by Ashish Ashu
    We are in need of a control in which we can show the elapsed time in "Hour:Min:Sec" format. This control should have a spin control attached with it. Whenever we spin the spin window, it should increment the selected option ( Either hour, or min , or sec). Also the Hour may have values between 0 to 99 , Min many have values between 0 to 59 and Sec may have values between 0 to 59. Is anybody know this type of control in WPF?

  • sort mysql query by filtered query

    - by kalpaitch
    I have two mysql queries: $sql = "SELECT * FROM content WHERE threadName LIKE '%$filter%' ORDER BY lastUpdated desc"; and $sql = "SELECT * FROM content ORDER BY lastUpdated desc"; The end result is to have all rows returned from a particular table 'content' but have those that match the variable $filter at the top. Is there either a single query that could combine these two or should I be using a JOIN?

  • Fair Contract salary compared to permanent salary

    - by Ngu Soon Hui
    Let's say I have a position open, it can either be contract or permanent position. The question is what is the fair amount of money I should pay for the contract position, if I am willing to pay X per month for the permanent role? Contract pays are inevitably higher, because the contractors are not entitled for a lot of benefits, and not guaranteed of a job. I know the exact ratio of contract to permanent varies from person to person, but I need a rule of thumb here.

  • Eclipse doesn’t recognize style in the Android Layout builder?

    - by Artem Russakovskii
    Since Android supports styles and it's good practice to use them (similar to CSS), I made a new style and applied it to 3 buttons. The Layout builder in Eclipse did not register the changes and either broke (showed nothing) or didn't apply styles at all. After running the app in the emulator, styles are correctly applied. So is there something I'm missing or the Android plugin doesn't support styles?

  • Hiding UITabBar when rotating device iPhone

    - by Tom G
    Has anyone successfully hidden a UITabbar when rotating the device? I have one view in the UItabbar controller that i rotate (So effectively one tab that rotates) When this happens i want the tab bar to disappear... but nothing seems to work! Either the tabbar still remains visible Or it disappears along with the view Or the tabbar disappears and the view no longer rotates! So if anyone has successfully accomplished this task any advice would be greatly appreciated! Thanks Tom

  • Comparing floating point values

    - by Sauron
    I just read a statement about the floating point value comparison Floating point values shall not be compared using either the == or != operators. Most floating point values have no exact binary representation and have a limited precision. If so what is the best method for comparing two floating point values?

  • Is the job title of "Webmaster" an anachronism?

    - by Phil.Wheeler
    I've worked with a few people who have the word "webmaster" either as part of their formal job title or as their actual title. The type of work these people do does relate loosely to the web, but I suspect better, more appropriate titles that more accurately reflect the job function would make more sense. Is the "webmaster" moniker still relevant today?
