  • C / JSON Library in popular Linux distros?

    - by Tim Post
    I have a program written in C that has to input and output JSON over a local domain socket. I've found several C / JSON libraries that 'almost work' through searches. Prior to taking one of the libraries that I found .. I want to be sure that I'm not over-looking a library that is commonly found on modern Linux distros. I'd also really appreciate links to libraries that you use. Most likely, I'll just drop it in tree, unless I realize that I've over looked something widely distributed. I am tagging this as subjective because the answer that I select is the one linking to a library that works for me, that does not mean its the 'best' library. I want to take an existing array and easily convert it to a buffer that can be sent, or take a buffer and easily convert it into an allocated array. Thanks in advance!

  • What is the most useful R trick?

    - by Dirk Eddelbuettel
    In order to share some more tips and tricks for R, what is you single-most useful feature or trick? Clever vectorization? Data input/output? Visualization and graphics? Statistical analysis? Special functions? The interactive environment itself? One item per post, and we will see if we get a winner by means of votes. [Edit 25-Aug 2008]: So after one week, it seems that the simple str() won the poll. As I like to recommend that one myself, it is an easy answer to accept.

  • Passing Results from SQL to Google Maps API in CodeIgniter

    - by Jason Shultz
    I'm hoping to use google maps on my site. My addresses are stored in a db. I’m pulling up a page where the information is all dynamic. For example: mysite.com/site/business/5 (where 5 is the id of the business). Let’s say I do a query like this: function addressForMap($id) { $this->db->select(‘b.id, b.busaddress, b.buscity, b.buszip’); $this->db->from(‘business as b’); $this->db->where(‘b.id, $id); } How can I output the info to the google maps api correctly so that it display’s the map appropriately? The API interface takes the results like this: $marker['address'] = 'Crescent Park, Palo Alto';

  • Create a triangle out of stars using only recursion

    - by Ramblingwood
    I need to to write a method that is called like printTriangle(5);. We need to create an iterative method and a recursive method (without ANY iteration). The output needs to look like this: * ** *** **** ***** This code works with the iterative but I can't adapt it to be recursive. public void printTriangle (int count) { int line = 1; while(line <= count) { for(int x = 1; x <= line; x++) { System.out.print("*"); } System.out.print("\n"); line++; } } I should not that you cannot use any class level variables or any external methods. Thanks.

    Here is the code: -(void)stop { NSLog(@"Disposing Sounds"); AudioServicesDisposeSystemSoundID (soundID); //AudioServicesRemoveSystemSoundCompletion (soundID); } static void completionCallback (SystemSoundID mySSID, void* myself) { NSLog(@"completion Callback"); } - (void) playall: (id) sender { [self stop]; AudioServicesAddSystemSoundCompletion (soundID,NULL,NULL, completionCallback, (void*) self); OSStatus err = kAudioServicesNoError; NSString *aiffPath = [[NSBundle mainBundle] pathForResource:@"slide1" ofType:@"m4a"]; NSURL *aiffURL = [NSURL fileURLWithPath:aiffPath]; err = AudioServicesCreateSystemSoundID((CFURLRef) aiffURL, &soundID); AudioServicesPlaySystemSound (soundID); NSLog(@"Done Playing"); } Output: Disposing Sounds Done Playing In actual no sound gets play at all and completion call back isn't called as well. Any idea what could be wrong here? I want to stop any previous sound before playing current.

  • Translate from Java to C#: simple code to re-encode a string

    - by Dr. Zim
    We were sent this formula to encrypt a string written in Java: String myInput = "test1234"; MessageDigest md = MessageDigest.getInstance("SHA"); byte[] myD = md.digest(myInput.getBytes()); BASE64Encoder en64 = new BASE64Encoder(); String myOutput = new String ( Java.net.URLEncoder.encode( en64.encode(myD))); // myOutput becomes "F009U%2Bx99bVTGwS3cQdHf%2BJcpCo%3D" Our attempt at writing this in C# is: System.Security.Cryptography.SHA1 sha1 = new System.Security.Cryptography.SHA1CryptoServiceProvider(); string myOutput = HttpUtility.UrlEncode( Convert.ToBase64String( sha1.ComputeHash( ASCIIEncoding.Default.GetBytes(myInput)))); However the output is no where near the same. It doesn't even have percent signs in it. Any chance anyone would know where we are going wrong?

  • FDF-files not opening properly

    - by Flyhard
    We have created a servlet that provides a FDF file for our clients. The FDF file is created by iText and the output looks fine. Whenever we open the FDF either from the Servlet, or from a local file, AcrobatReader starts, asks if the PDF should be downloaded, we allow that and then we see the PDF - without the values we filled in the form. One thing that seems strange is, that regardless of the Browser, we get prompted about what to do with the PDF file that Adobe has tried to load. Anything else that clicking "open" will result in a empty Acrobat viewer window. I suspect that Acrobat forgets what to do with the PDF - but I have run out of ideas. Anyone got an idea where to look further?

  • Powershell and some simple string manipulation

    - by Pat
    need some help with building a powershell script to help with some basic string manipulation. I know just enough powershell to get in trouble, but can't figure out the syntax or coding to make this work. I have a text file that looks like this - Here is your list of servers: server1 server2.domain.local server3 Total number of servers: 3 I need to take that text file and drop the first and last lines (Always first and last.) Then I need to take every other line and basically turn it into a CSV file. The final output should be a text file that looks like this - server1,server2.domain.local,server3 Any suggestions on where to start? Thanks!

  • Why '.png' files produced by ImageMagick are so much bigger than '.jpg' & '.gif' files?

    - by Nick Gorbikoff
    Hello. I'm using ImageMagick to convert some files from one format to another. I was always under the impression that .png files were supposed to be as big/small as .jpg if not smaller, and definitely smaller than .gif. However when I run convert photo.jpg photo.png The files I'm getting out is about 6 times bigger than the original jpg. Original jpg is a regular photo about 300x500 px, 52 kb. Output is a proper png of the same dimensions, but size is about 307 kb? Does anyoone know what the hack is going on? Am I doing something wrong? P.S.: I tried both on Debian and Windows with the same results.

  • Http Geocoder (Google) Accuracy level

    - by sushruth
    I am geocoding a large amount of user entered addresses and interested in the accuracy levels returned. My GOAL is to get the BEST POSSIBLE ACCURACY score for a given address. I call the geocder api following way http://maps.google.com/maps/geo?q={address}&output=csv&sensor=false&key=xx now the accuracy levels returned for same address with/without premise name q = Key Arena, 305 Harrison Street, Seattle, WA 98109 (Accuracy is 5) q = 305 Harrison Street Seattle, WA 98109 (Accuracy is 8) q = Key Arena, Seattle, WA 98109 (Accuracy is 9.) Its obvious from the above that the google servers does not return the best accuracy when street name is appended with premise/venue. the question is :) is there a way to pass the complete address ( with premise name / i.e case 1 ) and get the Max Accuracy. ( or how can tell the google server that the address is passed with premise/building name and street name) ( if you are thinking why not just use case 3, the answer is these are user entered addresses, they could enter "my moms's house" for premise, with accurate street address. in which case i want the accuracy to be 8 not 5)

  • Can we you the attached properties in C# class library?

    - by Manas Agarwal
    Hi I have implemented the Observer Pattern with lazy load. The class that requests the data from the database is a singleton class. Now I am able to load the data from one database (located in one datacenter) very easily. But I need to get the data from other data centers too and display on the same UI. I can somehow pass the address of second data center and fetch the data from there also. But once I will get the data from second data center, it will be added to earlier list only. So later it will be thought for me to distinguish between the data. So I thought of attaching a property with the result set, so that while displaying the output I can show the data for both the data centers separately but on the same UI. I thought of attached property as an option where I can attach the data center name with the list of the data obtained. How is it possible to do in C#? Thanks Manas

  • Alternatives to ASCX User Control without a server-side form?

    - by Andrew Murray
    I've got an ASP.NET 3.5 Web Forms application in which a large chunk of code needs to be duplicated between a few different pages. Sounds like the ideal candidate for a user-control right? Problem is, this cannot be contained within a <form runat="server"> because it contains a client-side form of it's own. There are no runat=server controls or postbacks or anything that really need that webform - think of it just as a chunk of HTML with a few basic <% %> tags. I'd just want to set a property on the control when it's loaded, so that it knows what to output. This is purely an exercise to make the code easier to maintain. Before I resort to using an oldskool <!--#include-->, is there some better way of doing this?

  • import existing source code as referenced library in eclipse

    - by user555174
    I have some source codes from a friend that I would like to use as referenced library in my BlackBerry project. I'm not sure about how to package the source codes into a .jar file. I tried exporting the source to a JAR file and import it as external JAR in my project, it's giving me missing stack map error. I tried to preverify the .jar file generated from the source using the provided preverification tool from BlackBerry JDE, it didn't give me any output folder. In fact, I'm not sure if the way I export the source is correct. Can anyone provide step-by-step instructions on how to package existing source code into a valid JAR file that can be imported into my project as a referenced library? Again, I'm using eclipse. Thanks very much in advance.

But if i make for example: this->ui->textEdit->setText(table[2]); I see third word in QTextEdit. What's wrong? Thank you.

  • Difficulty creating a paging function with MySQL and ColdFusion

    - by Mel
    I'm trying to create pagination for search results using MySQL and ColdFusion. My intention is to only retrieve the queries that can be displayed on a single page, thus making the process efficient. I tried using two queries in my function, but I could not return two variables to the cfinvoke. The following code does not paginate, but it displays the result search results using a CFC: <!---DEFINE DEFAULT STATE---> <cfparam name="variables.searchResponse" default=""> <cfparam name="URL.titleName" default=""> <cfparam name="URL.genreID" default=""> <cfparam name="URL.platformID" default=""> <!---TitleName can only be blank if one or both genre and platform are selected---> <cfif StructKeyExists(URL, "searchQuery") AND (Len(Trim(URL.titleName)) LTE 2 AND Len(URL.genreID) IS 0 AND Len(URL.platformID) IS 0)> <cfset variables.searchResponse = "invalidString"> <cfelseif StructKeyExists(URL, "searchQuery")> <cfinvoke component="gz.cfcomp.test" method="searchGames" returnvariable="resultData" argumentcollection="#URL#"> <cfset variables.searchResponse = "hasResult"> </cfif> <cfif searchResponse EQ "hasResult" AND resultData.RecordCount EQ 0> <cfset variables.searchResponse = "noResult"> </cfif> Using this logic, I can display what I need to display on the page: <cfif searchResponse EQ "invalidString"> <cfoutput>Invalid search</cfoutput> </cfif> <cfif searchResponse EQ "noResult"> <cfoutput>No results found</cfoutput> </cfif> <cfif searchResponse EQ "hasResult"> <cfoutput>Display Results</cfoutput> </cfif> If I were executing the queries on the same page, it would be easy to follow the many tutorials out there. But the queries are executing in a function. Displaying the data is easy, but paginating it has become a nightmare for me. Here is my function: <cffunction name="searchGames" access="public" output="false"> <cfargument name="titleName" required="no" type="string"> <cfargument name="genreID" required="no" type="string"> <cfargument name="platformID" required="no" type="string"> <!--- DEFINE LOCAL VARIABLES---> <cfset var resultData = ""> <!---GET DATA---> <cfquery name="resultData" datasource="myDSN"> SELECT * <!---JOINS FOR GENRE/PLATFORM GO HERE---> WHERE <!---CONDITIONS GO HERE---> </cfquery> <!---RETURN VARIABLE---> <cfreturn resultData> </cffunction> To paginate, I thought about modifying my function to the following (a new query using a count statement): <!--- DEFINE LOCAL VARIABLES---> <cfset var resultCount = ""> <!---GET DATA---> <cfquery name="resultCount" datasource="myDSN"> SELECT COUNT(gameID) AS rowsFound FROM GAMES <!---JOINS FOR GENRE/PLATFORM GO HERE---> WHERE <!---CONDITIONS GO HERE---> </cfquery> <!---RETURN VARIABLE---> <cfreturn resultCount> Then I figured if there is a result to return, I would execute a nested query and create the pagination variables: <cfif resultCount.rowsFound GTE 0> <cfparam name="pageNumber" default="1"> <cfset var recordsPerPage = 5> <cfset var numberOfPages = Int(resultCount.RecordCount / recordsPerPage)> <cfset var recordsToSkip = pageNumber * recordsPerPage - recordsPerPage> <!---DEFINE LOCAL VARIABLE---> <cfset var resultData = ""> <cfquery name="resultData" datasource="myDSN"> <!---GET DATA AND SEND IT BACK USING LIMIT WITH #recordsToSkip# and #RecordsPerPage#---> </cfquery> <!---RETURN VARIABLE---> <cfreturn resultData> </cffunction> I figured I would return two variables: resultCount and resultData. I would use #resultCount# to build my pagination, and #resultData# to display the output. The problem is I can't return two variables in the same cfinvoke tag. Any ideas of how to approach the the right way? I'm totally lost as to the logic I need to follow.

  • generic function for extracting values from an array with one particular key in PHP

    - by Sabya
    Is it possible in PHP to extract values from an array with a particular key path and return an array of those values? I'll explain with an example: $user = array ( array( id => 1, email =>'[email protected]', project => array ('project_id' => 222, 'project_name' => 'design') ), array( id => 2, email =>'[email protected]', project => array ('project_id' => 333, 'project_name' => 'design') ) ); /** I have to write a function something like: */ $projectIds = extractValuesWithKey($user, array('project', 'project_id')); print_r($projectIds); Output: Array( [0] => 222, [1] => 333 )

  • SQL Filter Multiple Tables Data

    - by Brad
    If it matters, I'm using Firebird 2.1 database. I have three tables, one with keywords, one with negative keywords, and the other with required keywords. I need to be able to filter the data so the output has just the keywords that meat the stipulation of not being in the negative keyword list, and IF there are any required words, then it will require the results to have those keywords in the end result. The tables are very similar, the field in the tables that I would be matching against are all called keyword. I don't know SQL very well at all. I'm guessing it would be something like SELECT keyword from keywordstable where keyword in requiredkeywordstable and where NOT in negativekeywordstable Just a side note, The required keywords table could be empty which would mean there are no required keywords. Any help would be appreciated. -Brad

  • C++ Testing framework integrated with Eclipse

    - by Mike
    I'm writing a C++ unit testing framework and I would like it if it could be integrated with Eclipse CDT. In other testing suites that work with Eclipse, JUnit for example, the user is provided a graphical list of all test cases and their results. Something like this would be the ideal. I'm just getting into this, so I need some advice on getting started. There are two approaches I see Use an existing Eclipse testing plugin (such as JUnit) and make the framework return output in the same format as the plugin's input. Write a plugin from scratch that can work with my framework (seems like it would take a lot of time) Thoughts appreciated
