• Checkbox in a Crystal Report

  - by JosephStyons

  What is the best way to display a checkbox in a Crystal Report? Example: My report has a box for "Male" and "Female", and one should be checked. My current workaround is to draw a small graphical square, and line it up with a formula which goes like this: if {table.gender} = "M" then "X" else " " This is a poor solution, because changing the font misaligns my "X" and the box around it, and it is absurdly tedious to squint at the screen and get a pixel-perfect alignment for every box (there are dozens). Does anyone have a better solution? I've thought about using the old-style terminal characters, but I'm not sure if they display properly in Crystal. Edit: I'm using Crystal XI.

• Deserialize array values to .NET properties using DataContractJsonSerializer

  - by James Cadd

  I'm working with the DataContractJsonSerializer in Silverlight 4 and would like to deserialize the following JSON: { "collectionname":"Books", "collectionitems": [ ["12345-67890",201, "Book One"], ["09876-54321",45, "Book Two"] ] } Into classes like the following: class BookCollection { public string collectionname { get; set; } public List<Book> collectionitems { get; set; } } class Book { public string Id { get; set; } public int NumberOfPages { get; set; } public string Title { get; set; } } What's the proper place to extend DataContractJsonSerializer to map the unnamed first array element in "collectionitems" to the Id property of the Book class, the second element to the NumberOfPages property and the final element to Title? I don't have control over the JSON generation in this instance and would like the solution to work with the Silverlight subset of .NET. It would be great if the solution could perform the reverse for serialization as well.

• How do I connect a dataGrid to a DataSet

  - by orangecl4now

  using System.Windows; namespace Telephone_Directory { /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); telephone2010DataSet dataSet = new telephone2010DataSet(); telephone2010DataSetTableAdapter adapter = new telephone2010DataSetTableAdapter(); } } } The above is my code is a new project. Visual Studio 2010 complains that " the type or namespace 'telephone2010DataSetTableAdapter' could not be found." I created a new solution. I right clicked the solution name and selected "Add Existing Item" and located my Microsoft Access DB file. I followed the wizard and it setup the necessary XSD files. I started coding and I got this message. I did a little google-ing and I cant figure it out. This is a WPF application created with Visual Studio 2010.

• How to solve this problem with lists?

  - by osabri

  what i don't understand in my task here what kind of list i can use, and if it should have 2 attributes key and value ? or only value? with pointers to another node ofc the task: "design a function which create a list using input from the keyboard _ the prefered solution. Assume that some magic stops the input; so the length of a list is not known in advance.(alternative solution: a function which creates explicitly a fixed list. However, all other function can not assume any knowledge about the length of lists). Necessary utilities( additional functions to be created): a function which deallocates the memory used for lists and a function which prints the content of the list. let the element of lists contain a letter. Design a function which create a copy of such list. can't also understand the list line !!!!!???

• white-label collaborative open-source development (e.g. github/sourceforge/google-code in a box) ?

  - by Justin Grant

  Does anyone have a recommendation for an open-source or paid (either packaged or SaaS) solution for integrating collaborative development features into your own website? Here's more details: We currently host an online plugin gallery for our product. Users can upload and download plugins. But users can't easily collaborate on a plugin's development, can't easily report and track bugs on a plugin, can't easily track a plugin's versions or roadmap, etc. Of course, contributors can host their plugin development on github, sourceforge, google code, codeplex, etc. But keeping users on our website has some advantages. For example: We can use single-sign-on to avoid yet another username/password required we can integrate end-user issue tracking into our existing online issue-tracking systems we can get integrated analytics so we can better meet the needs of top contributors as well as downloaders We can easily reward reputation points to committers just like we do for people who answer lots of questions Anyone know a good solution for white-label sites for open-source project developer collaboration?

• Truncate text if it atempts to run into three lines

  - by Jigs

  I have a small about 140px wide aligned next to a picture. In total there is space for four lines of text. The first two lines are reserved for the title and there are two lines of other info. I want the title to be cut if it spans more than two lines else it will push the other info out of line with the bottom of the image. The only solution I could think of was to create a div the height of two lines with an overflow to hidden. However, if the title is only one line it leaves a big gap. The solution can be Jquery, plain javascript, CSS or even PHP (if its possible). TIA

• Extract part of HTML in C/Objective-C

  - by Dan

  Hi, I need to extract the detail content of a website while preserve all formatting of the division. The section I wish to extract is: ... <div class="detailContent"><p> <P dir=ltr><STRONG>Hinweis</strong>: Auf ... </p> </div> ... My current solution is to use HTMLParser from libxml2 and xpath to find the nodes and walk through all the nodes to reconstruct this piece of HTML. This is a long an complicated code. I' just wondering if there is an easier solution to extract part of HTML? Thanks.

• Using same Debug settings for Start External Program across 32 bit and 64 bit debug environments

  - by Michael Prewecki

  We use a mixture of 32-bit and 64-bit development environments. Some of our class libraries are debugged using a 32-bit application so we have debug settings for "Start External Program" and "Working Directory". The problem is that the settings need to be different since the 32-bit application is installed to C:\Program Files\xxx (on the 32-bit dev enviroment) or C:\Program Files (x86)\xxx (on the 64-bit dev environment) Is there a way to use some sort of tag like %PROGRAMFILES% or $(ProgramFiles) so that Visual Studio 2008 will know where to look for the external program? This wouldn't be a major issue except the solution file (where the debug information is saved) is checked into source control...so getting the latest version of the solution from our source repository keeps yoyo'ing the debug settings between the two program files locations.

• Markdown to text/plain and text/html for multipart email

  - by fphilipe

  I’m looking for a solution to send DRY multipart emails in Rails. With DRY I mean that the content for the mail is only defined once. I’ve thought about some possible solutions but haven’t found any existing implementations. The solutions I’ve thought about are: load the text from I18n and apply Markdown for the html mail and apply Markdown with a special output type for the text mail where links are put in parenthesis after the link text bold, italic and other formatting that doesn't make sense are removed ordered and unordered lists are maintained generate only the html mail and convert that to text according to the above conditions Is there any available solution out there? Which one is probably the better way to do it?

• Security review of an authenticated Diffie Hellman variant

  - by mtraut

  EDIT I'm still hoping for some advice on this, i tried to clarify my intentions... When i came upon device pairing in my mobile communication framework i studied a lot of papers on this topic and and also got some input from previous questions here. But, i didn't find a ready to implement protocol solution - so i invented a derivate and as i'm no crypto geek i'm not sure about the security caveats of the final solution: The main questions are Is SHA256 sufficient as a commit function? Is the addition of the shared secret as an authentication info in the commit string safe? What is the overall security of the 1024 bit group DH I assume at most 2^-24 bit probability of succesful MITM attack (because of 24 bit challenge). Is this plausible? What may be the most promising attack (besides ripping the device out off my numb, cold hands) This is the algorithm sketch For first time pairing, a solution proposed in "Key agreement in peer-to-peer wireless networks" (DH-SC) is implemented. I based it on a commitment derived from: A fix "UUID" for the communicating entity/role (128 bit, sent at protocol start, before commitment) The public DH key (192 bit private key, based on the 1024 bit Oakley group) A 24 bit random challenge Commit is computed using SHA256 c = sha256( UUID || DH pub || Chall) Both parties exchange this commitment, open and transfer the plain content of the above values. The 24 bit random is displayed to the user for manual authentication DH session key (128 bytes, see above) is computed When the user opts for persistent pairing, the session key is stored with the remote UUID as a shared secret Next time devices connect, commit is computed by additionally hashing the previous DH session key before the random challenge. For sure it is not transfered when opening. c = sha256( UUID || DH pub || DH sess || Chall) Now the user is not bothered authenticating when the local party can derive the same commitment using his own, stored previous DH session key. After succesful connection the new DH session key becomes the new shared secret. As this does not exactly fit the protocols i found so far (and as such their security proofs), i'd be very interested to get an opinion from some more crypto enabled guys here. BTW. i did read about the "EKE" protocol, but i'm not sure what the extra security level is.

• Problem with assembly loading in .NET

  - by Jamie

  Hi guys, I have got two projects in my solution: Silverlight and standard one. The standard one references System.Xml assembly (version 4.0.0.0), however the Silverlight one references System.Xml assembly (v. 2.0.5.0). I want to make an instance of XmlWriter in my Silverlight project. Here comes the problem - the exception is thrown (file not found for System.Xml assembly). I believe it is a matter of different assembly versions. Do you have any idea how to resolve this issue? Ive read something about the binding redirection - is it the key to the solution? If so, how to do this? Thank you in advance for the reply! Cheers.

• Website with Microsites & Blog - recommendations

  - by pingu

  Hi guys, I'm in the process of scoping a solution for an events organisation. Their main website features information about them and blog entries etc, but they hold major events which require microsites (domain.com/event). The microsites all have a different look-and-feel, different nav structure, and custom content-managed components. The one thing that's common across everything is the blog - it will have a category for each event under which users can post. The main site will display all blog posts, but the microsites will only display posts for their category. How would you guys implement this? The solution needs to be PHP, and my initial thought was CodeIgniter but if possible I'd like to avoid building the blog functionality - so I guess I could integrate it with EE or Wordpress. If anyone has any other suggestions they would be most appreciated.

• What exactly does it mean when $_FILES is empty?

  - by Mike

  I am working on an upload script and when testing my error checks, I attempted to upload a 17MB TIFF file. When I do this the $_FILES array is empty. The script works fine for what I need it to do, which is to upload JPEG files. My solution is to test if $_FILES is empty or not before continuing with the upload script. Can anybody explain why $_FILES is empty when a TIFF is attempted to be uploaded? Is my solution, to check if $_FILES is empty or not, an okay one?

• Redirect Entry form in SharePoint back to itself once entry submitted?

  - by Marius

  The issue I have is that people in my group are using a link to an Entry Form to post new itmes to a SharePoint list. Everytime they click 'submit' to post new item, SharPoint redirects them to the list. I need a solution for SharePoint to direct them to the empty Entry form instead, no matter how many times they need to use it. Is there such solution? Thanks, I already have this "/EntryForm.aspx?Source=http://" in the link to the Entry form, but works only 2 times, after that will direct to the list.

• Document -> Flash viewer, not hosted

  - by Dane

  I've got a content management solution where we present scanned images (TIFF), PDFs, word docs for viewing. While we can simply embed a PDF, sometimes depending on user preferences it's a bit fiddly and sometimes not user-intuitive. I'd like a solution like scribd, embedit, etc, but not hosted. I want to run the application on our own servers and manage it that way (for legal reasons, and our clients won't buy the service if it's hosted somewhere else). SWFtools looks a little basic for my needs, plus doesn't do doc, docx or ppt. Any options? Doesn't have to be free, but would be ideal.

• Wrong code coverage on of unit test

  - by KamilPyc

  I'm using code coverage for unit tests in Xcode. Everything is working except some special cases, for example protocol declaration shows wrong values. If I have : @protocol SomeProtocole <NSObject> @property (nonatomic, readonly) NSObject *example; @end I will get 0% code coverage for this file. But I have unit test that is using class that conforms to that protocol. Only solution I found so far is to filter code coverage raport to not include protocols. But I would like to see real values for protocols. Any one have some solution to fix it?

• Javascript: variable scope & the evils of globals

  - by Nick

  I'm trying to be good, I really am, but I can't see how to do it :) Any advice on how to not use a global here would be greatly appreciated. Let's call the global G. Function A Builds G by AJAX Function B Uses G Function C Calls B Called by numerous event handlers attached to DOM elements (type 1) Function D Calls B Called by numerous event handlers attached to DOM elements (type 2) I can't see how I can get around using a global here. The DOM elements (types 1 & 2) are created in other functions (E&F) which are unconnected with A. I don't want to add G to each event handler (because it's large and there's lots of these event handlers), and doing so would require the same kind of solution as I'm seeking here (i.e., getting G to E&F). The global G, BTW, is an array that is necessary to build other elements as they, in turn, are built by AJAX. I'm not convinced that a singleton is real solution, either. Thanks.

• NP-complete problem in Prolog

  - by Ashley

  I saw this ECLiPSe solution to the problem mentioned in this XKCD comic. I tried to convert this to pure Prolog. go:- Total = 1505, Prices = [215, 275, 335, 355, 420, 580], length(Prices, N), length(Amounts, N), totalCost(Prices, Amounts, 0, Total), writeln(Total). totalCost([], [], TotalSoFar, TotalSoFar). totalCost([P|Prices], [A|Amounts], TotalSoFar, EndTotal):- between(0, 10, A), Cost is P*A, TotalSoFar1 is TotalSoFar + Cost, totalCost(Prices, Amounts, TotalSoFar1, EndTotal). I don't think that this is the best / most declarative solution that one can come up with. Does anyone have any suggestions for improvement? Thanks in advance!

• IIS5, ASP.NET (3.5) Application and Visual Studio 2008

  - by Lakeshore

  I have a solution that was developed in VS 2008 that is configured to use IIS. I configure the Virtual directory in IIS the same way I have with other working solutions using IIS. When I either build and run the solution in VS 2008 or browse the virtual directory using IIS, I get the following error message. Internet Explorer cannot display the webpage What you can try: It appears you are not connected to the Internet, but you might want to try to reconnect to the Internet Retype the address Go back to the previous page. Most likely causes: You are not connected to the Internet The website is encountering problems There might be a typing error in the address. Why might this be?

• ZeroMQ Java Installation Problem

  - by Ivan

  Hi everyone, I'm trying to install ZeroMQ's Java library but I've been having problem. First error was ./configure complained about JAVA_HOME which everything seemed to be fine but I couldn't manage to solve it but I've found a particular solution in ZeroMQ's chat logs. The suggested solution was; JAVA_HOME="/System/Library/Frameworks/JavaVM.framework/Home" ./configure However it doesn't work for me. The error message I've been receiving is checking for jni.h in /Library/Java/Home/include... configure: error: cannot find jni.h in /Library/Java/Home/include. I've tried JAVA_HOME="/System/Library/Frameworks/JavaVM.framework/Home" ./configure and JAVA_HOME="/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home" ./configure as well but still no luck. I'd like to hear StackOverflowers' thoughts about how I can solve this. Thanks.

• Exclusive filtering by tag

  - by KaptajnKold

  I'm using rails 3.0 and MySql 5.1 I have these three models: Question, Tag and QuestionTag. Tag has a column called name. Question has many Tags through QuestionTags and vice versa. Suppose I have n tag names. How do I find only the questions that have all n tags, identified by tag name. And how do I do it in a single query. (If you can convince me that doing it in more than one query is optimal, I'll be open to that) A pure rails 3 solution would be preferred, but I am not adverse to a pure SQL solution either.
