• Resizing to page width for print style sheet

  - by rampion

  So I've got a page that shows an image with some absolutely positioned text on top of it. I want to write a print style sheet for it so that: the image is resized to fit the width of the page the text is repositioned and resized to maintain relative position and size with the image behind it So I know I can do (1) with just max-width: 100%, but I'm not sure how to accomplish (2). I'm okay with using some javascript if necessary, but I wanted to know if there's a way to do this in pure CSS. If I do need to use javascript, what can I hook to check for the pixel width of the image in the printed page? Just use the calculated width as normal? And yes, this question might be more appropriate for DocType, but I've yet to get any help over there.

• UITableView not showing background image.

  - by K.Honda

  I have a uitableview with 2 cells (custom tableviewcells) and a button for login. I made them programmatically. Now I want to put a background image behind the 2 custom cells and the button. I went into IB and put the image view on top of the tableview and then put a picture on it which I want as the background. Then I went into viewDidLoad and put this bit of code tblSimpleTable.backgroundColor = [UIColor clearColor]; to clear the tableviews background colour. It now looks like this: But the background does not appear. Does anyone know how to fix this? Thanks.

• VC++ - Asynchronous Thread

  - by JVNR

  I am working on VC++ project, in that my application process a file from input path and generates 3 output "*.DAT" files in the destination path. I will FTP these DAT file to the destination server. After FTP, I need to delete only two output .DAT files the folder. I am able to delete those files, because there one Asynchronous thread running behind the process. Since the thread is running, while deleting it says, "Cannot delete, the file is used by another person". I need to stop that thread and delete the files. Multiple files can also be taken from the input path to process. Please help me in resolving this issue. Its very high priority issue for me. Please help me ASAP.

• How to Print reports in Silverlight 4

  - by AmbiguousX

  I am wondering if there is anything built in to Silverlight, or possibly c# to allow for printing reports? I'd be happy with any number of methods: exporting files to a pdf format and printing from there, exporting as a text document of some sort and printing from there, or just simply showing the print dialog from the web application itself. I know there are ways to do this in C#, but the c# code-behind is different for many things in Silverlight applications and I can't seem to find anything that will work. So if anyone has any ideas on things I could try it would be very much appreciated! Thank you!

• [FLEX 3] Placing images into a Collage Canvas

  - by Bridget

  I've got an array of different sized images. I want to place these images on a canvas in a sort of automated collage. Does anyone have an idea of how to work the logic behind this concept? All my images have heights divisible by 36 pixels and widths divisible by 9 pixels. They have mouseDown functions that allow you to drag and drop. When dropped the image goes to the closest x point divisible by 9 and y point divisble by 36. There is a grid drawn on top of the canvas. I've sorted the array of images based on height, then based on their widths. imagesArray.sortOn("height", Array.NUMERIC | Array.DESCENDING); imagesArray.sortOn("width", Array.NUMERIC | Array.DESCENDING); I'd like to take the largest image ( imageArray[0] ) to put in corner x,y = 0,0. Then randomize the rest of the images and fit them into the collage canvas.

• Problem using a costum server control in a aspx

  - by gre3ns0ul

  Hi guys, i am having a issue. I already developed one class (my custom gridview) and i want use it on a .aspx That class is defined in app_code and compiled to the dll of the project. namespace MyCostumControls{  public class DropDownPagingGridView : GridView{ ... I already registered the control on the aspx page using <%@ Register Namespace="MyCostumControls" TagPrefix="ctrl" % and i can use in the page and works ok.. But i'm watching one problem. That class contains methods defined by me, than when i try to call them in code-behind sayd to me than they're not defined. In designed i don't see the reference to MyCostumControls, and when i try declare one field using protected global::MyCostumControls.MyCostumControls ddl_gv_errors, i cannot access to MyCostumControls namespace, Is because he's compiled to the project dll? I can access to all namespaces than are not contained in app_code. Solutions? Apreciate. Thanks

• Converting button events etc to ASP.NET MVC

  - by Sophie88

  Given an asp.net webform page which does something like asp.net <asp:textbox id="txtA" runat="server" /> <asp:textbox id="txtB" runat="server" /> <asp:button id="btnAddTogether" runat="server" text="Go" onclick="btn_Click"/> <asp:textbox id="txtResult" runat="server" /> code behind protected void btn_Click(...) { txtResult.Text = txtA.Text + txtB.Text; } How would I convert this to ASP.NET MVC. It's a pretty trivial example, but I'm not sure about how to change my way of thinking.

• How to convert server time to local time?

  - by Lost_in_code

  My php file is hosted in some other part of the world. The date() and time() functions returns the date/time on the server. How do I convert that date so that it's the same as my local date/time? The date on the server is 10 hours behind my local time. I could just hard code and substract this from the server time. But what is the proper way of going about this so that no value has to be hardcoded?

• Fastest method for SQL Server inserts, updates, selects

  - by Ian

  I use SPs and this isn't an SP vs code-behind "Build your SQL command" question. I'm looking for a high-throughput method for a backend app that handles many small transactions. I use SQLDataReader for most of the returns since forward only works in most cases for me. I've seen it done many ways, and used most of them myself. Methods that define and accept the stored procedure parameters as parameters themselves and build using cmd.Parameters.Add (with or without specifying the DB value type and/or length) Assembling your SP params and their values into an array or hashtable, then passing to a more abstract method that parses the collection and then runs cmd.Parameters.Add Classes that represent tables, initializing the class upon need, setting the public properties that represent the table fields, and calling methods like Save, Load, etc I'm sure there are others I've seen but can't think of at the moment as well. I'm open to all suggestions.

• Determining where a function is defined in C#?

  - by templatetypedef

  Hey all - I am a complete novice at C# (I've never used it before) and recently needed to look over some code written in it. I spent the longest time trying to track down a nonexistent method in a class that didn't seem to be defined anywhere in the class that was using it. I later found out it was an "extension method," which I gather is a method grafted onto another class by some source. I completely understand the rationale behind this language feature and actually think it's quite nice. However, as someone without much experience in the language, it makes it harder to look up unfamiliar methods, since the method in question could be defined anywhere. My question is this: given an unfamiliar method call in C#, what's the best way for me to look up more info on it, given that it could be an extension method defined in an entirely separate class? Thanks!

• SEO on a login based website

  - by Paul

  Ok so say I have a website that the majority of content is behind a closed door, login screen for paying customers only. How can I let google know what is there so people can find the site through a search engine. What programming techniques could I use to give more content to the google bot. I will have some overview and demonstration screens to tempt the users but will these five to ten pages of content be enough for the search engines. The key work is quite a highly sort one and there is quite alot of competition. And before anyone asks the site is not a subscription porn site (Sadly)

• How do you get GWT 2.0 to accept clicks on two different Widgets added to a LayoutPanel?

  - by kerrr

  Using GWT 2.0 I have an entry point that adds two Widgets to a LayoutPanel. The Widgets both handle click events and have click events ergistered to them. The problem is that only the last widget added to the LayoutPanel can actually be clicked. Switch the order in which the widgets are added switches the widget that works. Add mroe widgets and still the only you can click is the last one added to the LayoutPanel. Any idea why this is? Is there any reasoning behind the behaviour, or have I missunderstood what is happening under the covers? How do I gat all widgets in the LayoutPanel to accept events? Should I be using another panel class? I'm not too bothered if the LayoutPanel prevents anything below it from being clicked, but want all Widgets added to it to be clickable.

• How to use git to download a particular tag?

  - by Jack BeNimble

  I'm trying to figure out how do download a particular tag of a git repository - it's one version behind the current version. I saw there was a tag for the previous version on the git web page, with object name of something long hex number. But the version name is "Tagged release 1.1.5" according the site. I tried a command like this (with names changed): git clone http://git.abc.net/git/abc.git my_abc And I did get something - a directory, a bunch of subdirectories, etc. If it's the whole repository, how do I get at the version I'm seeking? If not, how do I download that particular version?

• Why do you sometimes need to write <typename T> instead of just <T> ?

  - by StackedCrooked

  I was reading the Wikipedia article on SFINAE and encountered following code sample: struct Test { typedef int Type; }; template < typename T > void f( typename T::Type ) {} // definition #1 template < typename T > void f( T ) {} // definition #2 void foo() { f< Test > ( 10 ); //call #1 f< int > ( 10 ); //call #2 without error thanks to SFINAE } Now I've actually written code like this before, and somehow intuitively I knew that I needed to type "typename T" instead of just "T". However, it would be nice to know the actual logic behind it. Anyone care to explain?

• If I had to create a server farm what should I do? (how others companies work?)

  - by Michel

  I have a business idea but this is not really my field so I'm trying to understand what I'm really dealing with. I have a general understanding of how a web farm works, I'm a web developer and I understand the technology behind it, but I'm curious to know specifically how a web farm is set up and which professionals are involved. Things to consider probably are the hardware, the power supply, the software managment, the cooling system and if possible the usage of green technology/power recycling. Basically, can you explain me how a web hosting company is structured and how it works? A big question, I know, but from what I already read here about the subject a lot of you know this stuff. Thanks for your time guys!

• Java concurrency - Should block or yield?

  - by teto

  Hi, I have multiple threads each one with its own private concurrent queue and all they do is run an infinite loop retrieving messages from it. It could happen that one of the queues doesn't receive messages for a period of time (maybe a couple seconds), and also they could come in big bursts and fast processing is necessary. I would like to know what would be the most appropriate to do in the first case: use a blocking queue and block the thread until I have more input or do a Thread.yield()? I want to have as much CPU resources available as possible at a given time, as the number of concurrent threads may increase with time, but also I don't want the message processing to fall behind, as there is no guarantee of when the thread will be reescheduled for execution when doing a yield(). I know that hardware, operating system and other factors play an important role here, but setting that aside and looking at it from a Java (JVM?) point of view, what would be the most optimal?

• How to map an property of ClassA to one of SuperclassA?

  - by mystify

  I have a class named SuperclassA, and an class named ClassA. ClassA inherits from SuperclassA. SuperclassA has got an property called something, so a very generic not-much-saying name. In ClassA, I want to have an property which maps to that something of SuperclassA. How could I do that? I want to make absolutely sure that any access to myBetterProperty results in accessing what's behind something. Assigning an value to myBetterProperty should result in assigning one to something, and vice versa. How to? Pointers set up in init? How would that look like? *self.myBetterProperty = &something; ? I'm not sure about that...

• getElementById does return null

  - by pbcoder

  I have following function: $('canvas').createWindow('xyz', 500, 600); And js-code behind is: var $ = function(element) { if (this.constructor !== $) { return new $(element); } alert(element); var windowObj = document.getElementById(element); this.createWindow = function(src, width, height) { if(width != "" && height != "") { windowWidth = windowObj.style.width = width + 'px'; windowHeight = windowObj.style.height = height + 'px'; } }; }; But the problem is that JS says windowObj is null, alert(element) works fine! Thanks for your help!

• Will Haskell be a good choice for my task?

  - by Narzanka

  I'm starting a new project and don't know which language to use. My 'must have' requirements are: Be able to run on Windows/LinuxMacOs natively (native executable) - user should be able to just run the exe (when on Windows for example) and see the results. No runtimes/interpreters (no jvm, clr, etc) - one file download should be enough to run the application. Full unicode support. Be able to manipulate OS threads (create them, run multiple tasks in parallel on multi-core CPUs, etc). Be reasonably fast (Python level performance and better). To have some kind of standard library that does low-level, mundane tasks. Not very niche and have some community behind it to be able to ask questions. My 'nice to have' requirements are: Language should be functional It should have good string manipulation capabilities (not necessarily regex) Not extremely hard to learn I'm thinking about Haskell now but keeping in mind OCaml as well. Please advice if my choice is correct.

• Python profiler and CPU seconds

  - by dude

  Hey, I'm totally behind this topic. Yesterday I was doing profiling using Python profiler module for some script I'm working on, and the unit for time spent was a 'CPU second'. Can anyone remind me with the definition of it? For example for some profiling I got: 200.750 CPU seconds. What does that supposed to mean? At other case and for time consuming process I got: -347.977 CPU seconds, a negative number! Is there anyway I can convert that time, to calendar time? Cheers,

• AJAX Panel not throwing exceptions

  - by Grant

  Hi, i have just noticed something strange in some asp.net markup. I have a standard form with a couple of textboxes and a submit button. When clicked the code behind will attempt to perform some logic and then return. If the input values are not valid it used to throw an exception. The moment i wrapped the controls in an AJAX update panel and try to submit bad data, no exception is thrown and the panel returns like nothing was wrong. Does anyone know how to return this to the previous behavior whilst keeping the update panel?

• How does * work in Python

  - by Deqing

  Just switched from C++ to Python, and found that sometimes it is a little hard to understand ideas behind Python. I guess, a variable is a reference to the real object. For example, a=(1,2,5) meaning a - (1,2,5), so if b=a, then b and a are 2 references pointing to the same (1,2,5). It is a little like pointers in C/C++. If I have: def foo(a,b,c): print a,b,c a=(1,3,5) foo(*a) What does * mean here? Looks like it expands tuple a to a[0], a[1] and a[2]. But why print(*a) is not working while print(a[0],a[1],a[2]) works fine?

• Entity diagram with tables that have foreign keys that point to a non-PK column do not show relation

  - by Jason Coyne

  I have two tables parent and child. If I make a foreign key on child that points to the primary key of parent, and then make an entity diagram, the relationship is shown correctly. If I make the foreign key point to a different column, the relationship is not shown. I have tried adding indexes to the column, but it does not have an effect. The database is sqlite, but I am not sure if that has an effect since its all hidden behind ADO.net. How do I get the relationship to work correctly?

• Basic iphone timer example

  - by Rob

  Okay, I have searched online and even looked in a couple of books for the answer because I can't understand the apple documentation for the NSTimer. I am trying to implement 2 timers on the same view that each have 3 buttons (START - STOP - RESET). The first timer counts down from 2 minutes and then beeps. The second timer counts up from 00:00 indefinitely. I am assuming that all of the code will be written in the methods behind the 3 different buttons but I am completely lost trying to read the apple documentation. Any help would be greatly appreciated.
