    I'm wondering how I could create a gradient wuth multiple stops and a direction if I'm making polygons. Right now I'm creating gradients by changing the color of the verticies but this is limiting. Is there another way to do this? Thanks

  • If I'm updating a DataRow, do I lock the entire DataTable or just the DataRow?

    - by Dan Tao
    Suppose I'm accessing a DataTable from multiple threads. If I want to access a particular row, I suspect I need to lock that operation (I could be mistaken about this, but at least I know this way I'm safe): // this is a strongly-typed table OrdersRow row = null; lock (orderTable.Rows.SyncRoot) { row = orderTable.FindByOrderId(myOrderId); } But then, if I want to update that row, should I lock the table (or rather, the table's Rows.SyncRoot object) again, or can I simply lock the row?

  • MSDN Subscription Expression Studio 4 licence details

    - by pjk
    I logged into my MSDN subscription (Premium) today to download the new expression studio, and I noticed that unlike Expression 3, it requires you to enter a key, and they only provide 1. Previously I installed Expression 3 on 2 computer, my home and my work computer. So my question is, is this no longer allowed? or is it a key that can be used multiple times?

  • ReSharper-like addon for NetBeans

    - by Ondrej Slinták
    Hello, is there any ReSharper-like addon for NetBeans (preferably 6.8)? I'm using NetBeans for PHP. I need following features: add some kind of code analysis add some intelligent refactoring interface enhance current code completion system add more options to code highlighting Currently I'm using multiple external tools, which aren't exactly user-friendly and I'd like to, preferably, have it all in one tool. Perhaps some other PHP IDE have something like this. EDIT: Bit more details in my answer to Jani Hartikainen.

  • Cocoa - Timer object that can be started, suspended, resumed?

    - by psychotik
    I'm looking for a repeating timer object that allows me to create it once and then suspend and resume it as needed for the lifetime of my application. I've seen documentation for NSTimer and although I think I can make it do what I want by building an abstraction on top of it that creates/invalidates timer objects multiple times, I was curios if there is a better way using some other system timer implementation. I'm not too familiar with Mac development and couldn't find any other leads besides NSTimer.

  • tableSorter limitation (sort) one page at a time?

    - by Abu Hamzah
    i see that in tableSorter you can sort one page at a time which concerns me. Only 1 page of results can be sorted at a time?, which is pretty limiting. If you have a query result that spans multiple pages, how you will handle this? If anyone knows better, feel free to correct me if iam incorrect Thanks.

  • Django database caching

    - by hekevintran
    The object user has a foreign key relationship to address. Is there a difference between samples 1 and 2? Does sample 1 run the query multiple times? Or is the address object cached? # Sample 1 country = user.address.country city = user.address.city state = user.address.state # Sample 2 address = user.address country = address.country city = address.city state = address.state

  • Unit of Work Pattern in .Net

    - by Jazza
    Does anyone have any concrete examples of a simple Unit of Work pattern in C# or Visual Basic that would handle the following scenario? I'm writing a WinForms application in which a customer can have multiple addresses associated with it. The user can add, edit and delete addresses belonging to the customer before the customer is saved back to the database. Therefore, at the time of saving, all the original addresses need to be deleted from the database and the new addresses added in a single transaction.

  • What should be the ideal number of parallel java threads for copying a large set of files from a qua

    - by ukgenie
    What should be the ideal number of parallel java threads for copying a large set of files from a quad core linux box to an external shared folder? I can see that with a single thread it is taking a hell lot of time to move the files one by one. Multiple threads is improving the copy performance, but I don't know what should be the exact number of threads. I am using Java executor service to create the thread pool.

  • Alternatives to web.config files in ASP.NET

    - by Ben Aston
    In my experience, web.config files are widely reviled. In particular, I have found them difficult to manage when you have multiple environments to support, and fiddly to update due to the lack of validation at update-time and the verbosity of XML. What are the alternatives?

  • How can I call a function at the very end of document.ready

    - by Umair
    I have multiple document.ready functions on a page and I want a function to be called when all my document.ready functions have been executed. I simply want the function to be called at the very end, after all other document.ready functions have executed. An example of this could be that each document.ready function increments a global variable when it has been executed, and the last function needs to check the value of that variable at the very end. Any ideas ?

  • Move jQuery data() when an element is destroyed and re-created

    - by Ed Woodcock
    Can anyone think of a (preferably quick) way to move the data() attached to a DOM element to a new instance of itself? The lightbox plugin I'm using deletes and re-appends and element to the page in order to display it in the lightbox (to aviod the multiple-ids issue that ASP.net has), and obviously the .data() that is attached to the element is lost when this happens.

  • Speeding Up Slow, CPU-Intensive Scrolling in WinForms

    - by S B
    How can I speed up the scrolling of UserControls in a WinForms app.? My main form has trouble scrolling quickly on slow machines--painting for each of the small scroll increments is CPU intensive. My form has roughly fifty UserControls (with multiple fields) positioned one below the other. I’ve tried intercepting OnScroll and UserPaint in order to eliminate some of the unnecessary re-paints for very small scroll events, but the underlying Paint gets called anyway. How can I streamline scrolling on slower machines?

  • Is choiceMode compatible with ExpandableListView?

    - by kostmo
    Is it possible to make a multiple choice list with android:choiceMode="multipleChoice" or setChoiceMode(ListView.CHOICE_MODE_MULTIPLE) on an ExpandableListView? I am able to do this with CheckBoxes on a plain ListView, but it doesn't seem to be working with ExpandableListView. In the latter, clicking the list item (either parent or child) does not affect the checkbox as it does in the former. I have noticed that it is possible to click exactly on the checkbox to make it toggle, but this is a very small target.

  • How to do REST securely and with sensitive data?

    - by Earlz
    Hello, we are implementing a new web service. The web service will be a store of sensitive data and there are multiple users types with different permissions. So some user types can't access(and some can't change, and so on) certain types of data. How would this work in REST? I'm very new to REST, so sorry if this sounds noobish.
