• What is the better approach to find if a given set is a perfect subset of a set - If given subset is

  - by Microkernel

  Hi guys, What is the best approach to find if a given set(unsorted) is a perfect subset of a main set. I got to do some validation in my program where I got to compare the clients request set with the registered internal capability set. I thought of doing by having internal capability set sorted(will not change once registered) and do Binary search for each element in the client's request set. Is it the best I could get? I suspected that there might be better approach. Any idea? Regards, Microkernel

• Interacting with java code from C#

  - by Qua

  We've written a Java program which we are looking to use and interact with from C#. What are our options? Optimally it would be possible to compile the Java application as a library (.DLL) that we could reference from C# perhaps using P/Invoke. This, however, doesn't appear to be an option according to the first few searches online. We opt to be able to use ASP.NET to built a search engine powered by the Java code, so if this opens up for any other options please let us know.

• ghc can't find my cabal installed packages

  - by nont

  I've installed ghc 6.12.3, and then the Haskell Platform. I'm trying to compile a test program: $ ghc test.hs test.hs:3:0: Failed to load interface for `Bindings': Use -v to see a list of the files searched for. so, naturally, I do cabal install Bindings Which works fine, and places the package in ~/.cabal/lib/bindings-0.1.2 The problem is, that when I go to compile again with ghc, it still doesn't find the package I've installed with cabal. compiling in verbose mode gives: ghc -v test.hs Using binary package database: /home/ludflu/ghc/lib/ghc-6.12.3/package.conf.d/package.cache Using binary package database: /home/ludflu/.ghc/x86_64-linux 6.12.3/package.conf.d/package.cache As suggested by another stackoverflow user, I tried: ghc-pkg describe rts > rts.pkg vi rts.pkg # add the /home/ludflu/.cabal/lib to `library-dirs` field ghc-pkg update rts.pkg But to no avail. How to I add the .cabal to the list of package directories to search? Thank you!

• Do people create and use Web Parts connections?

  - by Javaman59

  I've been writing some SharePoint web parts wich connect (as providers and consumers). I've found many difficulties, and (comparatively*) little material from the web, from books, or from microsoft.com, which is quite surprising as Web Parts have been around since 2003. This is making me think that although web part connections look like a first class feature in SharePoint, that in practice few people write connecting web parts, and few SharePoint users use them. Is this the case - that few developers write connecting web parts, and few users use them? *comparitively: A subjective impression. With each specific problem i usually find only a handful of web pages which address it, and as my problems seem to be fundamental ones (such which data type to wrap in an IWebPartRow), I expect a lot more search results.

• Looking for a good explanation of the table generation macro idiom

  - by detly

  I want to make this clear up front : I know how this trick works, what I want is a link to a clear explanation to share with others. One of the answers to a C macro question talks about the "X macro" or "not yet defined macro" idiom. This involves defining something like: #define MAGIC_LIST \ X(name_1, default_1) \ X(name_2, default_2) \ ... Then to create, say, an array of values with named indices you do: typedef enum { #define X(name, val) name, MAGIC_LIST #undef X } NamedDefaults; You can repeat the procedure with a different #define for X() to create an array of values, and maybe debugging strings, etc. I'd like a link to a clear explanation of how this works, pitched at someone who is passably familiar with C. I have no idea what everyone usually calls this pattern, though, so my attempts to search the web for it have failed thus far. (If there is such an explanation on SO, that'd be fine...)

• Create pdf file dynamically in vb.net for .net 1.1 framework

  - by Urbycoz

  I need to create a pdf file dynamically in vb.net. It needs to contain several images and lines of text. I am using VS 2003, so whatever solution I use will need to be compatible with the .net 1.1 framework. The current method I am using is wpcubed, but this requires that all images be converted to bmp format before adding them to the pdf, which can be extremely slow when dealing with a large number of images. I am aware that there are an awful lot of other 3rd party products that claim to do this, and I have had a search through them. But without registering, downloading, installing and writing code to use each of them in turn, it is very difficult to differentiate between them. So far I have looked into evo pdf and pdfsharp but neither seem to work with .net 1.1. (Although they don't make this abundantly clear.) Has anyone else found a method that works and they would recommend (a free one-if possible)?

• Joining links together in a dictionary

  - by ptabatt

  Hi guys, I'm student here, new to python and programming in general. I have a dictionary links which holds a tuple mapped to a number. How can I join the second url in the second tuple together with the urljoin() function? What I'm trying to do is get complete links so I can run a recursive function search() which takes a complete url as an arguement, finds all the links in each url and stores the number of links mapped to the links in a database. So far, I have: links {('href', 'http://reed.cs.depaul.edu/lperkovic/csc242/test2.html'): 1, ('href', 'test3.html'): 1} I want http://reed.cs.depaul.edu/lperkovic/csc242/test3.html...

• charset problem?

  - by Ben Fransen

  Hi all, I have a bugging problem. For a website I made there are search engine friendly URL's generated. The only problem is there are ß-chars in the url too. Chars like ö, ï, ä, ü etc. are placed correct. But with the ß-char there is a diamond-icon with a questionmark in it. I thought it had to do with the charset which is used but i've tried both UTF-8 and iso-8859-1. Both without luck. I need to have the correct character in the url for the readability of deeplinks. Hope to hear from you!

• How can I change the filename of a shared library after building a program that depends on it?

  - by ZorbaTHut

  I have a program that depends on a shared library it expects to find deep inside a directory structure. I'd like to move that shared library out and into a better place. On OS X, this can be done with install_name_tool. I'm unable to find an equivalent for Linux. For reference, readelf -d myprogram spits out the following paraphrased output: Dynamic section at offset 0x1e9ed4 contains 30 entries: Tag Type Name/Value 0x00000001 (NEEDED) Shared library: [this/is/terrible/library.so] 0x00000001 (NEEDED) Shared library: [libGL.so.1] 0x00000001 (NEEDED) Shared library: [libGLU.so.1] 0x00000001 (NEEDED) Shared library: [libstdc++.so.6] and I would like to errata "this/is/terrible/library.so" to be "shared/library.so". I know about RPATH and it isn't what I'm looking for, I don't need to change search paths globally.

• Linq-to-Sql query advice please

  - by Mantorok

  Hi all Just wondering if this is a good approach, I need to search for items containing all of the specified keywords in a space-delimted string, is this the right approach this? var result = (from row in DataContext.PublishedEvents join link in DataContext.PublishedEvent_EventDateTimes on row.guid equals link.container join time in DataContext.EventDateTimes on link.item equals time.guid orderby row.EventName select new {row, time}); // Split the keyword(s) to limit results with all of those words in. foreach(var keyword in request.Title.Split(" ".ToCharArray(), StringSplitOptions.RemoveEmptyEntries)) { var val = keyword; result = result.Where(row=>row.row.EventName.Contains(val)); } var end = result.Select(row=>new EventDetails { Title = row.row.EventName, Description = TrimDescription(row.row.Description), StartDate = row.time.StartDate, EndDate = row.time.EndDate, Url = string.Format(ConfigurationManager.AppSettings["EventUrl"], row.row.guid) }); response.Total = end.Count(); response.Result = end.ToArray(); Is there a slick Linq-way of doing all of this in one query? Thanks

• Remove a toolbar when pushing a new view

  - by nevan

  In the iPhone maps app there's a toolbar at the bottom of the map view (it contains the Search/Directions segment control and others). When moving from the map view by clicking on a callout, the toolbar slides out with the map view, leaving the next view (a table controller) with no toolbar. I've tried to do the same thing with [self.navigationController setToolbarHidden:YES animated:YES] in the second view controller, but this gives a strange toolbar sliding down animation, while the map view is sliding to the left. Using [self.navigationController setToolbarHidden:YES] in viewDidLoad:animated also causes a bad effect (it makes the toolbar disappear the moment the push animation starts, leaving an ugly white space). I'm assuming the answer to this is to use a nib file, but I'd prefer to do it programatically (if possible). How can I get the toolbar to "stick" to the map view and slide out with it when I push a new view controller? Thanks.

• Where does one get Visual Source Safe 2005?

  - by strongopinions

  I would like to install VSS 2005 so I can work on a project that is stored under it. Does anyone have any idea where the VSS 2005 client can be obtained? It does not appear to be on my VS2005 install disc (although that is for Team Suite). I cannot get any help from Google. I have an MSDN license (AA edition) but it doesn't seem to be there. This is a real product right? Just to clarify preemptively based on some of the discussions I see on Google when I search for things like "VSS 2005," I am aware of the flaws in VSS and I still need to get it working; I am not interested in converting the project to Subversion; I am not able to transfer it to TFS; I am not able to upgrade the project to VS2008. Thanks.

• Map a domain to an MVC area

  - by Simon_Weaver

  Anybody got any experience in mapping a domain to an MVC area? Here's our situation: Old system (still active but will soon redirect to new store): www.example.com - our main site where we send traffic store.example.com - our store site which is a completely separate site that is indexed in google New system: www.example.com - same site as before www.example.com/store - new store site - built in an ASP.NET MVC area Because store is a separate domain google gives it a separate entry in the search results. I'd like to keep this benefit in future but wondering whether or not there is a good way to map a domain (store.example.com) to the MVC area or if its just going to be more trouble than its worth. PS. I'm not trying to keep existing indexing - its a completely separate store so thats not possible. I just want to redirect to the corresponding page in the new store. I'm just trying not to lose the benefit of two domains for SEO purposes.

• Python comparing string against several regular expressions

  - by maerics

  I'm pretty experienced with Perl and Ruby but new to Python so I'm hoping someone can show me the Pythonic way to accomplish the following task. I want to compare several lines against multiple regular expressions and retrieve the matching group. In Ruby it would be something like this: STDIN.each_line do |line| case line when /^A:(.*?)$/ then puts "FOO: #{$1}" when /^B:(.*?)$/ then puts "BAR: #{$1}" # when ... else puts "NO MATCH: #{line}" end end My attempts in Python are turning out pretty ugly because the matching group is returned from a call to match/search on a regular expression and Python has no assignment in conditionals or switch statements. What's the Pythonic way to do (or think!) about this problem?

• update table with information from IDirectory

  - by sue

  I have a table with 4 columns, LoginID, LastName, FirstName, Email. The data for LoginID was populated from an other table. I have to write a small routine to update this table, by sending in the LoginID and with help of IDirectory routines, get the Lastname, firstname and email. This is what i'm attempting to do, but getting confused with the right syntax. using (TSADRequestEntities context = UnityHelper.Resolve()) { var fpvalues = context.FOCALPOINTs.ToList(); foreach (var item in fpvalues) { IEnumerable<UserInfo> query = UnityHelper.Resolve<IUserDirectory>().Search(item.LoginID); //Here, FocalPoint is the table that has the loginID and the other fields //I need to update. the query shld now hv info on lastname etc..how do I //retrieve that value and update the table? } }

• Hiding the console window in a system() call

  - by Justen

  Continuing from this question With each system call, the function constructs a set of parameters and sends them off to another program that is just console-based. Is there a way I can make it so that no console window pops up for each call? I've done a search but the ones that aren't a linker issue just aren't working for me. For instance, I tried the _execl call and System::Diagnostics::Process^ myProcess = gcnew System::Diagnostics::Process; but they aren't working. The _execl will bring a console window up, scroll a bunch of stuff (from the program I called I guess), then close the my app and not even do what it was supposed to do. The System::Diagnostics::Process^ myProcess = gcnew System::Diagnostics::Process; doesn't seem to execute what I want either because the output folder that should contain files, contains nothing. So I'm open for ideas.

• is a mysql temporary table unique for each user accessing the script that creates it...?

  - by SpikETidE

  Hi everyone... While looking for a way to temporarily save the search results when a user searches for a hotel free between particular dates i came across temporary tables. But certain questions are not answered even in mysql manual.... like... Will the temporary table be unique for each user that executes the script...? Or will it be overwritten when two different users run the script at the same time...? When will the table be destroyed..? When the user closes the browser window or just navigates away from the page in which the script runs...? Thanks for your clarifications...

• Any "trick" to use some keys to launch an application?

  - by Profete162

  Hello, I am currently developing an free application (TaskOS ) that allow users to have multitasking and switch easily between applications on their mobile ( like alt+tab in Windows ) That work pretty well and user can launch my application by a long press on the "search" button" by adding this line in the manifest: <action android:name="android.intent.action.SEARCH_LONG_PRESS" /> I also succeed to allow to the users to Use the camera button ( they can of course disable that in application settings) and the way to do that is slighlty different: <receiver android:name=".CameraPressed"> <intent-filter android:priority="10000"> <action android:name="android.intent.action.CAMERA_BUTTON"/> </intent-filter> I am now wondering if there are other ways to launch easily my task switcher? ( long press on Home key, long press on trackball, or any other idea.) Reading the Google documentation does not help me a lot. Any other idea/suggestion would be warmly welcome. Christophe

• set / line intersection solution

  - by Xavier

  I have two lists in python and I want to know if they intersect at the same index. Is there a mathematical way of solving this? For example if I have [9,8,7,6,5] and [3,4,5,6,7] I'd like a simple and efficient formula/algorithm that finds that at index 3 they intersect. I know I could do a search just wondering if there is a better way. I know there is a formula to solve two lines in y = mx + b form by subtracting them from each other but my "line" isn't truly a line because its limited to the items in the list and it may have curves. Any help is appreciated.

• Loading...Please wait for UIWebView - iPhone

  - by niha7229

  Hi guys, In Safari and other browsers, there is a bar that would indicate the percentage of the loading progress, and I, myself, trying to implement something similiar on iPhone, when loading some content in UIWebView, I would like the app to indicate the percentage of the page being loaded. I tried some google search and realize we could use NSURLConnection to read only the header and get the Content-Length ( but don't know how to, I read the Apple's NSURLConnection docs but probably I missed something ... ). And the size ( kb ) which UIWebView had loaded, seem like UIWebView don't support it for the public API... I hope this would be complete in some other ways than I thought, so if you have any ideas, please throw it out, thanks for your patient reading. P.S : I could just show an Activities Indicator for users with the long loading progress actions of the UIWebView but I just want to go further with the loading percentage bar :). Regards.

• Regex for Searching for Text Not Preceeded By a Specific String

  - by James

  Hi, I am working on a web site with several other developers and we have had problems where people commit JavaScript code with AJAX calls that use URL's relative to the site root. An example would be /Home/Index which will not work if the site is hosted in a virtual directory. To get round the problem we use a $.url() method to convert it to a full path, e.g. $("#container").load($.url("/Home/Index")) I am trying to write a unit test that will search each JavaScript file and find places where the $.url method is not being used. The only problem is that I cannot seem to write a regex expression to do this. I have tried the following: (?!\$\.url\()"(/\w*)+" But this does not work. I cannot find a way to say that I don't want the $.url in front. Does anyone know if this is possible? Note that I need regular expressions that are compatible with .NET Thanks.

• Using GET instead of POST to delete data behind authenticated pages

  - by Matt Spradley

  I know you should use POST whenever data will be modified on a public website. There are several reasons including the fact that search engines will follow all the links and modify the data. My question is do you think it is OK to use GET behind authenticated pages in something like an admin interface? One example would be a list of products with a delete link on each row. Since the only way to get to the page is if you are logged in, is there any harm in just using a link with the product ID in the query string?
