  • Grid view w/ progress bars?

    - by Mark
    Trying to decide on the best element to use for a grid view, pretty much exactly like the one you'd see in uTorrent or any other upload/download client. Specifically, I want to have a 'progress' column too (with progress bars). Using VS2010/.NET4. What would you recommend?

  • Generic collection class?

    - by Mark
    Is there anyway I can do this? class TSOC<TCollection, TValue> : ICollection<TValue>, INotifyCollectionChanged where TCollection : ICollection { private TCollection<TValue> collection; } It doesn't like my definition of collection. I'd prefer the definition to look like TSOC<TCollection> where the user can pass in List<int> or something, but then I need to pull out the "int" to know what interface to implement.

  • How to Use a Windows App with Embeded files and folders to copy to a destination. In C#

    - by Mark Sweetman
    I am trying to write a small application, whose only purpose is to copy some folders and .cs source files into a user specified Directory, I can do it easy enough by simply having the application look for the files and folders in its own install directory then copy them to thier destination Directory, but I was wondering if its possible to Embed the Folders and Files into the Application, so that when you run the application it creates or copies the folders and files from the exe app directly to the install directory, rather than searching for them in the apps install directory then copying them over. Basically Im trying to only have a single exe file rather than having an exe file and a bunch of folders and files along side it. Is this possible to do with just a Windows Form App without using an actual Installer Class?

  • JQuery validation based on class?

    - by Mark Kadlec
    I have a form that will have dynamically created elements, one of those will be of date type. There can also be many fields of this type on my form, all which must be validated. I am using a strongly typed view in Asp MVC, so the name will change based on various factors. What I would like to do is validate based on a class name instead, since that will be constant for that type of field. Ie: <%= Html.TextBox("questionAnswers[" + index + "].AnswerValue", qa.AnswerValue, new { @class = "DateTypeClass" })%> So then I would need JQuery validation based on the classname DateTypeClass versus the Name. Any ideas?

  • javascript Programmically exit fullsreen

    - by Mark
    I understand why browsers would disallow websites from programically making the browser fullscreen. However, users typically expect the 'esc' button to exit from full screen, and browsers simply don't do that. Is there any way to get the browser to exit from full screen. Thanks.

  • Find multiple patterns with a single preg_match_all in PHP

    - by Mark
    Using PHP and preg_match_all I'm trying to get all the HTML content between the following tags (and the tags also): <p>paragraph text</p> don't take this <ul><li>item 1</li><li>item 2</li></ul> don't take this <table><tr><td>table content</td></tr></table> I can get one of them just fine: preg_match_all("(<p>(.*)</p>)siU", $content, $matches, PREG_SET_ORDER); Is there a way to get all the <p></p> <ul></ul> <table></table> content with a single preg_match_all? I need them to come out in the order they were found so I can echo the content and it will make sense. So if I did a preg_match_all on the above content then iterated through the $matches array it would echo: <p>paragraph text</p> <ul><li>item 1</li><li>item 2</li></ul> <table><tr><td>table content</td></tr></table>

  • Birthday effect - clarification needed plz.

    - by Mark
    Please help interpret the Birthday effect as described in Wikipedia: A birthday attack works as follows: 1) Pick any message m and compute h(m). 2) Update list L. Check if h(m) is in the list L. 3) if (h(m),m) is already in L, a colliding message pair has been found. else save the pair (h(m),m) in the list L and go back to step 1. From the birthday paradox we know that we can expect to find a matching entry, after performing about 2^(n/2) hash evaluations. Does the above mean 2^(n/2) iterations through the above entire loop (i.e. 2^(n/2) returns to step 1), OR does it mean 2^(n/2) comparisons to individual items already in L.

  • Best method for creating absolute path in PHP? (See 3 methods listed inside)

    - by mark
    I can create paths with no problem, but I want to know which of these 3 methods is the most rock solid and reliable and will work on the most servers. Right now I am using method 1 in my script and some users are having path issues. I just want the method that will work on any version of php and almost any server config. 1. <?php echo $_SERVER['DOCUMENT_ROOT']; ?> 2. <?php echo getcwd(); ?> 3. <?php echo dirname(__FILE__); ?> Thank you so much for any expertise you can provide about this!

  • Django model data consistency

    - by Mark
    When creating a form, you can define a bunch of methods, clean_xyz, to make sure the data gets forced into the correct format. Is there any way to do this on a model level? Perhaps I can override the field setters somehow? I want it so that if I write something like my_address.postal_code = 'a1b2c3' It will automatically get formatted into A1B 2C3. Perhaps throw an exception if it can't be converted. That way I know I'll never have any malformed data in the database.

  • How to display two QuerySets in one table?

    - by Mark
    I have two different QuerySets which both return a list of Users (with different fields). How can I display them both in one HTML table? One Query will always be a subset of the other; I just want to fill in the missing data with 0s. How can I do this?

  • for (Object object : list) [java] construction

    - by EugeneP
    My question, is, whether the sequence of elements picked from a list will always be the same, is this construction behaviour is deterministic for java "List"s - descendants of java.util.List 2) question, if I use for(Object o: list) construction and inside the loop's body increment a variable, will it be the index of list's elements? So, how it goes through list's elements, from 0 to size()-1 or chaotically? List.get(i) will always return this element? 3) question ( I suppose for the 2-nd question the answer will be negative, so:) for (int i=0; i < list.size(); i++) { } is the best way if I need to save the index of an element and later get it back from a list by its id?

  • How to pass in password to pg_dump?

    - by Mark
    I'm trying to create a cronjob to back up my database every night before something catastrophic happens. It looks like this command should meet my needs: pg_dump dbname | gzip > $(date +%Y-%m-%d).psql.gz Except after running that, it expects me to type in a password. I can't do that if I run it from cron. How can I pass one in automatically?

  • Google webfonts

    - by Mark
    Google webfonts look horrible on windows. What is going on? Is this a temporary problem that will be fixed, or is this just a windows problem that will forever persist? If the latter, doesn't that mean the entire project is sort of useless? Thanks in advance.

  • Getting screen height before first display?

    - by Mark
    Hi, I have a ListView. I populate it with 8 items, that's all that fits vertically on the G1. Some of my users are saying the Droid has a taller screen height, and so I can probably add one or two more items to the ListView to take up the additional space provided. How could I measure the available height the screen offers at startup, before the UI is displayed? If I see the height can fit more than 8 items, I'd like to add one or two more rows, Thanks

  • Avoiding instanceof in Java

    - by Mark Lutton
    Having a chain of "instanceof" operations is considered a "code smell". The standard answer is "use polymorphism". How would I do it in this case? There are a number of subclasses of a base class; none of them are under my control. An analogous situation would be with the Java classes Integer, Double, BigDecimal etc. if (obj instanceof Integer) {NumberStuff.handle((Integer)obj);} else if (obj instanceof BigDecimal) {BigDecimalStuff.handle((BigDecimal)obj);} else if (obj instanceof Double) {DoubleStuff.handle((Double)obj);} I do have control over NumberStuff and so on. I don't want to use many lines of code where a few lines would do. (Sometimes I make a HashMap mapping Integer.class to an instance of IntegerStuff, BigDecimal.class to an instance of BigDecimalStuff etc. But today I want something simpler.) I'd like something as simple as this: public static handle(Integer num) { ... } public static handle(BigDecimal num) { ... } But Java just doesn't work that way. I'd like to use static methods when formatting. The things I'm formatting are composite, where a Thing1 can contain an array Thing2s and a Thing2 can contain an array of Thing1s. I had a problem when I implemented my formatters like this: class Thing1Formatter { private static Thing2Formatter thing2Formatter = new Thing2Formatter(); public format(Thing thing) { thing2Formatter.format(thing.innerThing2); } } class Thing2Formatter { private static Thing1Formatter thing1Formatter = new Thing1Formatter(); public format(Thing2 thing) { thing1Formatter.format(thing.innerThing1); } } Yes, I know the HashMap and a bit more code can fix that too. But the "instanceof" seems so readable and maintainable by comparison. Is there anything simple but not smelly?
