  • Functions without arguments, with unit as argument in scala

    - by scout
    def foo(x:Int, f:Unit=>Int) = println(f()) foo(2, {Unit => 3+4} //case1 def loop:Int = 7 foo(2, loop) //does not compile changing loop to //case 2 def loop():Int = 7 foo(2, loop) // does not compile changing loop to //case 3 def loop(x:Unit): Int = 7 //changing according to Don's Comments foo(2,loop) // compiles and works fine should'nt case 1 and case 2 also work? why are they not working? defining foo as def foo(x:Int, y:()=>Int) then case 2 works but not case 1. Arent they all supposed to work, defining the functions either way. //also i think ()=Int in foo is a bad style, y:=Int does not work, comments??

  • How to enable ListView overscroll in HTC One X (may be all htc devices)?

    - by smeghead
    I have a listview in my app, and in my Xoom, and Galaxy S2, you get the normal glow effect when you overscroll. But in HTC One X, it doesn't show any overscroll behaviour. All the HTC apps have an accordion style overscroll behaviour. Do they use some custom listview? In any case, how do I show some sort of overscroll effect in HTC phones? Also, is there some ListView class out there, that implements overscroll effects on all phones (doesn't have to be the same effect). Some Context: The phones are on Android 4.0.3, and Xoom is on 4.0.4. The app is using the Holo Light theme. The min/target API level (as well as the Project API level) is set to 15.

  • How do I change the background image of my app?

    - by user356387
    Hello I have looked around and found some code which so called chooses an image from an array of image objects, but cant find an explanation. I would like to make my app have a background image and the user can select next and previous buttons to scroll through some full screen images, setting them as the background image as they scroll. I know how to do this in java, but cant seem to do it for this app. How or what code is linked to a next button to grab the next image in the array and reverse for the back button? Then that needs to be displayed obviously. I have used a layered architecture with a MVC style approach but cant seem to put it together with Objective-C. Would the buttons call the appropriate methods of the so called delegates, which the delegates handle fetching and returning the Images? Would the buttons use the returned images and actually handle the redrawing? I would really appreciate the help. Regards Jarryd

  • 2 table SQL Query weird results

    - by javArc
    Ok this is driving me nuts, I need to write an SQL query that will grab product information from 2 tables. The first table 'products' contains the productId, productname, quantityperunit and unitprice. Now I can search by productname and categoryname individually, but when I try to combine the 2 I get crazy results, Here's the query: "SELECT DISTINCT productId, productname, quantityperunit, unitprice FROM products pr, categories ca WHERE pr.categoryID = ca.categoryID AND ProductName LIKE '%" + searchTerm + "%' OR CategoryName LIKE '%" + searchTerm + "%' excuse the java style in there, here it is formatted better: SELECT DISTINCT productId, productname, quantityperunit, unitprice FROM products pr, categories ca WHERE pr.categoryID = ca.categoryID AND ProductName LIKE 'Tofu' OR CategoryName LIKE 'Tofu' any help would be appreciated.

  • Does specifying image size in CSS allow the browser to do layout before download is complete?

    - by eaolson
    I've always tried to specify the height and width attributes for img tags in HTML. Not for style reasons, but because the browser then expects the size of the image and can do page layout even before the image has finished downloading. From the HTML spec: The height and width attributes give user agents an idea of the size of an image or object so that they may reserve space for it and continue rendering the document while waiting for the image data. I don't know why this has never occurred to me, but does specifying height and width in CSS, rather than inside the img tag, do the same thing?

  • Form validation in JAvascript with Regexp

    - by Nikita Barsukov
    I have a webpage with an input field where only digits are allowed. The input field has an onkeyup event that starts this validating function: function validate() { var uah_amount = document.getElementById("UAH").value; var allowed = /^\d+$/; document.getElementById("error").innerHTML = document.getElementById("UAH").value; if (!allowed.test(uah_amount)) { document.getElementById("error").style.backgroundColor = "red"; } } Everything works as I expect until I hit Backspace button to remove some characters. In this case function always behaves as if I entered letters. How to correct this?

  • How do I count list elements that are not hidden?

    - by Baloneysammitch
    Starting with a simple list: <ul> <li>Item 1</li> <li style="display: none;">Item 2</li> <li>Item 3</li> </ul> I know that I can subtract the hidden elements from the list total $('ul li').size() - $('ul li:hidden').size() But I thought there might be a more elegant way to achieve this with jquery: $('ul li:hidden:not').size() That doesn't work. Any ideas?

  • Developer salaries to rise?

    - by rmbarnes
    I have heard people say that the large fall in people graduating with CS based degrees will soon cause developer salaries to rise due to the effects of a smaller supply but ever increasing demand. Do people really think that this is true? To my mind there are a couple of reasons this won't happen: Outsourcing With 'DIY' style languages like PHP and the attitudes of many of the communities behind these languages becoming ever more popular (e.g. the learn yourself, don't need to go to university way of thinking) not many employers will care if developers have degrees in CS or not.

  • C# Get/Set Syntax Usage

    - by RoR
    These are declarations for a Person class. protected int ID { get; set; } protected string Title { get; set; } protected string Description { get; set; } protected TimeSpan jobLength { get; set; } How do I go about using the get/set? In main, I instantiate a Person Tom = new Person(); How does Tom.set/get?? I am use to doing C++ style where you just write out the int getAge() and void setAge() functions. But in C# there are shortcuts handling get and set?

  • [C++] which is better, throw an exception or return nonzero value?

    - by xis19
    While you are doing C++ programming, you have two choices of reporting an error. I suppose many teachers would suggest you throw an exception, which is derived from std::exception. Another way, which might be more "C" style, is to return a non-zero value, as zero is "ERROR_SUCCESS". Definitively, return an exception can provide much more information of the error and recovery; while the code will bloat a little bit, and making exception-safe in your mind is a little difficult for me, at least. Other way like returning something else, will make reporting an error much easier; the defect is that managing recovery will be a possibly big problem. So folks, as good programmers, which would be your preference, not considering your boss' opinion? For me, I would like to return some nonzero values.

  • Chaining your own method in Ruby on Rails

    - by steven_noble
    In my Rails app, I am used to using syntax like the following in a number of places, including helpers/application_helper.rb: def my_method(x,y) return x+y end I am also used to calling the resulting method from basically anywhere in my app using syntax like this: my_method(2,3) However, I'd like to be able to use syntax like like this: class_from_my_rails_app.my_method(3) How and where do I define my_method so I can use it like this? I'm happy to consult the documentation, but I just don't know what the latter style is called. What do you call it? Many thanks, Steven.

  • .htacess windows problem

    - by pistacchio
    Hi, In the root directory of a small site i'm developing i have the following .htacess file: Options +FollowSymLinks RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-F RewriteRule .$ index.php that basically allows me to have pretty urls as it remaps every path that does not exists on the server (eg : /user/details/145 ) as a call to index.php where I handle it MVC-style. While this works ok on MacOs, this morning I have to work on another machine that has Windows (the apache server is run by xampp) and it does not work as it seems to redirect all the calls (eg those to static files like images) to index.php Any help?

  • mysql_close(): supplied argument is not a valid MySQL-Link resource

    - by maxedison
    I'm trying to get the hang of using custom session handlers to store session data in a MySQL database. However, I keep getting the following warning: mysql_close(): supplied argument is not a valid MySQL-Link resource Here's the code I'm using, which I got from here: function _open(){ global $_sess_db; $_sess_db = mysql_connect("localhost", "root", "******"); if ($_sess_db) { return mysql_select_db('style', $_sess_db); } return false; } function _close(){ global $_sess_db; return mysql_close($_sess_db); //error happens here } The full text of the error message ultimately points to the final "return mysql_close($_sess_db);" line. I can confirm that the mysql_connect info does in fact work, and I do have the rest of the session handler functions defined as well. And in case it helps, I get these errors immediately upon page load, without actually calling any of the session handler functions, and without having any current sessions open.

  • DIV appear differently in chrome only.

    I have a website at bgflirt.com that appears differently in FireFox and Chrome. This is how it looks in firefox: and here's how it looks in chrome: As you can see, in chrome (and safari) the page is not stretched to fit the entire screen. I'm using this code for positioning the div containing the flash on the right: <div style="width: 200px; position: absolute; right: 0px; top: 10px; overflow: hidden;"> </div> The page should look the way it does in firefox, in all browsers. Any ideas on how to fix this will be greatly appreciated !
