  • Unable to retrieve data from SQLite database iOS6.0

    - by kunalg
    When i run build ios5.0 or less then Sqlite response correct and retrieve data its work fine but when run on ios6.0 i am trying to fetch data from my.sqlite database but it is not executing my if case. It always enters in else condition. What wrong thing i am doing? I am not able to execute my if case i.e. if(sqlite3_prepare_v2(database, sqlQuerry, -1, &querryStatement, NULL)==SQLITE_OK). for reference check this code . NSLog(@"sqlite3_prepare_v2 = %d SQLITE_OK %d ",sqlite3_prepare_v2(sqlite, [strQuery UTF8String], -1, &compiledStatement, nil),SQLITE_OK); if(sqlite3_prepare_v2(sqlite, [strQuery UTF8String], -1, &compiledStatement, nil)==SQLITE_OK) { NSLog(@"sqlite3_step = %d SQLITE_ROW %d ",sqlite3_step(compiledStatement),SQLITE_ROW); while (sqlite3_step(compiledStatement)==SQLITE_ROW) { if(sqlite3_column_text(compiledStatement, 2) != nil) modelObj.Name = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 2)]; } } else { } ////////// in ios6.0 log Print sqlite3_prepare_v2 = 1 SQLITE_OK 0 sqlite3_step = 21 SQLITE_ROW 100 in iOS5.0 log Print sqlite3_prepare_v2 = 0 SQLITE_OK 0 sqlite3_step = 100 SQLITE_ROW 100

  • Filter zipcodes by proximity in Django with the Spherical Law of Cosines

    - by spiffytech
    I'm trying to handle proximity search for a basic store locater in Django. Rather than haul PostGIS around with my app just so I can use GeoDjango's distance filter, I'd like to use the Spherical Law of Cosines distance formula in a model query. I'd like all of the calculations to be done in the database in one query, for efficiency. An example MySQL query from The Internet implementing the Spherical Law of Cosines like this: SELECT id, ( 3959 * acos( cos( radians(37) ) * cos( radians( lat ) ) * cos( radians( lng ) - radians(-122) ) + sin( radians(37) ) * sin( radians( lat ) ) ) ) AS distance FROM stores HAVING distance < 25 ORDER BY distance LIMIT 0 , 20; The query needs to reference the Zipcode ForeignKey for each store's lat/lng values. How can I make all of this work in a Django model query?

  • How to replace 'dash' with 'underscore' in an IIRF rule?

    - by jessegavin
    I have a web app which serves images based on the subdomain. We wanted to provide our users with a url like this: http://{username}.domain.com/images/myimage.jpg Instead of what we used to have: http://www.reallylongdomainname.com/users/{username}/images/myimage.jpg This makes the url shorter and less 'snoopable'. So I set up an IIRF .ini file to do some url rewriting and it works great except for the fact that some of our users folders have an underscore. And from what I've read, underscore is not a valid character in a domain name (even though IIS supports it). I want to know how I could do a find and replace in the $1 back reference so that a url like this: http://some-user.domain.com/... Could be rewritten to this: /users/some_user/.. Here's my IIRF rule. RewriteCond %{HTTP_HOST} ^(?!www)([^\.]+)\.domain\.com RewriteRule ^/(.*)$ /users/*1/$1 [L,I] Thanks for any help.

  • Sum an Array - Objective-C

    - by Graham
    Hi Guys, I'm just starting out and I'm looking for an easy way to sum a simple array. I've read into apple developer site on key value coding and I don't understand how to apply that to my array or if that's the appropriate way to sum this. My stumbling block with the key value coding is the .keypathToProperty - I can sort of understand that you need a further reference in a 2D array but they don't show the array code, only the keypath to the title of the row so I can't figure it out yet. NSMutableArray *numArray = [NSMutableArray arrayWithCapacity:4]; [numArray addObject:num1]; [numArray addObject:num2]; [numArray addObject:num3]; [numArray addObject:num4]; I appreciate the replies! Thanks Graham

  • Easy Way for Non-Nerd to Manage Simple Site?

    - by Mark Evans
    Hi I'm not sure if this is an appropriate question for StackOverflow. I have a friend show wants a simple "Brochure Ware" web site. I could make it for him but it would be better if he could manage it himself. Are there any services out there that allow a non-technical person to create and maintain a very simple site? I'm thinking just a few pages - contact, about, home with some photos and general info. He also wants to sell some stuff but I'm going to suggest he does this using EBay but the web site would be a handy reference for potential customers who want to know more about him and his services. Thanks a lot! Cheers Mark

  • Renaming ICSharpCode.SharpZipLib.dll

    - by John B.
    Hi, well I am having a problem renaming the ICSharpCode.SharpZipLib.dll file to anythig else. I am trying to shorten the file name. I reference the assembly in the project, but when the program reaches the statements where I use the library. It spawns an error that it could not find the assembly or file 'ICSharpCode.SharpZipLib'. When I change the file name back to ICSharpCode.SharpZipLib.dll the application works noramally. So, is there any way to change the file name. Also, am I allowed to change it without violating the license (I am going to use it in a commercial application). Thanks.

  • How do I work with WIndows Forms in WPF?

    - by xarzu
    How do I work with WIndows Forms in WPF? In my WPF program I created a Windows Form class. In this Form, I placed an OK button and I went into the properties of the button and set the DialogResult to OK. Now, I am calling this Dialog (Window Form) from the MainWindow.xaml.cs: dres = form.ShowDialog(); if (dres != DialogResult.OK) return; The compiler is complaining: Error 3 'System.Nullable<bool>' does not contain a definition for 'OK' and no extension method 'OK' accepting a first argument of type 'System.Nullable<bool>' could be found (are you missing a using directive or an assembly reference?)

  • SQL multiple primary keys - localization

    - by Max Malmgren
    I am trying to implement some localization in my database. It looks something like this (prefixes only for clarification) tbl-Categories ID Language Name tbl-Articles ID CategoryID Now, in my tbl-Categories, I want to have primary keys spanning ID and language, so that every combination of ID and language is unique. In tbl-Articles I would like a foreign key to reference ID in categories, but not Language, since I do not want to bind an article to a certain language, only category. Of course, I cannot add a foreign key to part of the primary key. I also cannot have the primary key only on the ID of categories, since then there can only be one language. Having no primary keys disables foreign keys altogether, and that is also not a great solution. Do you have any ideas how I can solve this in an elegant fashion? Thanks.

  • ASP.net error message when using REST starter kit

    - by jonhobbs
    Hi all, I've written some code using the REST starter kit and it works fine on my development machine. However, when I upload it to our server the page gives me the following error message... CS1684: Warning as Error: Reference to type 'System.Runtime.Serialization.Json.DataContractJsonSerializer' claims it is defined in 'c:\WINNT\assembly\GAC_MSIL\System.ServiceModel.Web\3.5.0.0__31bf3856ad364e35\System.ServiceModel.Web.dll', but it could not be found I've removed code line by line and it appears that the following line of code is triggering the error... HttpContent newOrganizationContent = HttpContentExtensions.CreateXmlSerializable(newOrganizationXml); Really haven't got a clue how to fix it. I assumed it might be because it needs a newer version of the framework to run, but looking in IIS it says it's running version 2.0.50727 which I think is the lates version because it says that even when we're using framework 3.5 Very confused, any ideas?

  • Binary search of unaccesible data field in ldap from python

    - by EricR
    I'm interested in reproducing a particular python script. I have a friend who was accessing an ldap database, without authentication. There was a particular field of interest, we'll call it nin (an integer) for reference, and this field wasn't accessible without proper authentication. However, my friend managed to access this field through some sort of binary search (rather than just looping through integers) on the data; he would check the first digit, check if it was greater or less than the starting value, he would augment that until it returned a true value indicating existence, adding digits and continuing checking until he found the exact value of the integer nin. Any ideas on how he went about this? I've access to a similarly set up database.

  • In an ASP.NET MVC site, where would the JQuery code go?

    - by Maxim Z.
    I'm just getting started with ASP.NET MVC. I'm going to be using JQuery on the website I'm making, but I'm not really sure about one thing: where would JQuery code be placed? This concerns two things: Where do I import the JQuery JavaScript file? (I've been thinking that the Master page would be a good place to do this; am I right, or do I have to import it in each view?) Should all my JQuery code be referenced from the Master page (i.e., I store my code that uses JQuery in a separate .js file and reference it in a <script> tag)? Thanks in advance.

  • Compiler/Linking Error: Freedup

    - by nym
    I've been trying to compile a program for hardlinking duplicate files called freedup. I did try to email the author/maintainer of the program, but it's been a long time and I haven't heard anything back from him. I'm trying to compile the program from a cygwin environment using the latest stable versions of gcc (3.4.4-999) and make (3.81-2). I've tried deleting all the object files and running make, but I always get the following error: freedup.o: In function 'main': /home/[user]/freedup-1.5/freedup.c:1791: undefined reference to '_hashed' collect2: ld returned 1 exit status make: * * * [freedup] Error 1 I did take a look at the source code and saw that the "hashed" function is an inline function (which I didn't think had to be declared outside of the source file... but that's just what I gathered from some preliminary googling). If anyone would be kind enough to try compiling this program in a windows environment and has any luck, I'd really appreciate it. Thanks The direct link for the source files is: http://freedup.org/freedup-1.5-3-src.tgz

  • How does mysql define DISTINCT()

    - by goran
    AFAIK SQL defines two uses of DISTINCT keywords - SELECT DISTINCT field... and SELECT COUNT(DISTINCT field) ... However in one of web applications that I administer I've noticed performance issues on queries like SELECT DISTINCT(field1), field2, field3 ... DISTINCT() on a single column makes no sense and I am almost sure it is interpreted as SELECT DISTINCT field1, field2, field3 ... but how can I prove this? I've searched mysql site for a reference on this particular syntax but could not find any. Does anyone have a link to definition of DISTINCT() in mysql or knows about other authoritative source on this? Best

  • How to center an R plot after removing axis labels

    - by ConnorG
    I'm working on visualizing a matrix in R (almost exactly like http://reference.wolfram.com/mathematica/ref/MatrixPlot.html), and I've been using image(<matrix>,axes=FALSE) to draw the picture. However, I noticed that with the y-axis turned off, the plot isn't centered--the space is still there for the axis ticks + label. I can finagle some centering with par(oma=c(0,0,0,2.5)) but this seems inefficient and error-prone (if my matrix were to change dimensions/become non-square). Is there a better way to force the graphic to center? The right hand margin is significantly smaller than the left.

  • Use boost date_time to parse and create HTTP-dates

    - by John Price
    I'm writing a kind of HTTP proxy, so I need to be able to do 3 things: Parse an HTTP-date given any of the 3 formats specified in RFC 2616, sec 3.3, Convert a file date-time to an HTTP-date string, and Output the date to a string. For reference, theses are examples of the date-times I need to parse. I will output only the first format: Sun, 06 Nov 1994 08:49:37 GMT ; RFC 822, updated by RFC 1123 Sunday, 06-Nov-94 08:49:37 GMT ; RFC 850, obsoleted by RFC 1036 Sun Nov 6 08:49:37 1994 ; ANSI C's asctime() format I'm pretty sure Boost date_time can do all of this, but I'm having some trouble with number 1. Does anyone already have code to do this? Perhaps I'm not using google proficiently, but I can't find an example of how to do this with boost anywhere. Thanks for any help!

  • Start multiple processes of a dll in delphi

    - by Tom
    I have a "ActiveX library" project created with Delphi 2007. The library interface return XML data based on input values. This is then used by a PHP script that displays the data on a web page. This works great! The problem is that i can only run one instance of the dll process on the server. However, for security reasons, each of my customer should be able to access their own process of the dll (because the dll is always connected to only one database). Also, because of the way the delphi code is built, it doesn't support multiple threads. (It's a 100 000+ lines project using lots of singleton classes) Is there a way of starting several instances of the same dll? Is there a better way of transferring XML data from delphi to PHP? Sorry for the longish question, any help is appreciated (ps. I know the delphi code should be refactored, but this would mean 6 months of "circular reference" -hell :)

  • Why is the servlet request not available in the portlet API

    - by John Smith
    The portlet API deos not provide any reference to the enclosing servlet request and response objects. I know it is not the preferred model of interaction with the user, but it seems draconian to remove all access. I understand that for portlet driven interaction with the user, you want to use portlet URLs, and let the portlet container manage all the complexity. However if you have a number of portlets which are basically showing variants of the same data, it makes sense for them to be able to use the enclosing request to drive the data. We ended up using using a Liferay specific call to get the request, and it all seems to work as we wish. However I do feel the guilt. So my question really is, is there an underlying deep reason for the prohibition, or is it just to enforce the authors view of the API environment?

  • C# ASP.Net The type or namespace name 'iAnywhere' could not be found

    - by Louis Russell
    Morning all, I know that this sounds like a simple referencing problem from the title this is becoming a nightmare! I have a code class that uses the "iAnywhere.Data.AsaClient.dll". This Dll is referenced in the project and in the code class I have added this dll in the Using section. Everything seems fine at build with no errors at all but when I go to run the application it comes up with the following Compilation Error: Compiler Error Message: CS0246: The type or namespace name 'iAnywhere' could not be found (are you missing a using directive or an assembly reference?) The line that the Error points to this line in the class: using iAnywhere.Data.AsaClient; I have set the dll to copy local and it makes no difference, the Dll is installed on my PC so is in the GAC, I use this Dll with many other C# projects and have no problems. I have scoured Google looking for an answer and haven't found anything that points me to an answer to my problem. Any help would be brilliant!

  • How to access system.webserver web.config node in .NET 2

    - by JK
    Are there any .NET APis that can read/update the system.webServer node in web.config? I know I can do it via reading/parsing the web.config file as xml but that's awkward. To read/update the system.web node in .NET 2 I can use: HttpModulesSection httpModulesSection = (HttpModulesSection)configuration.GetSection("system.web/httpModules"); But is there any API based way of accessing system.web/modules using .NET 2? I have to reference the .NET 2 version of system.web.configuration because I don't know in advance if my web app will be run on a server with .NET 2 or 3.5. So it is limited to .NET 2 API calls only. Thanks

  • MYSQL Inner Join two table over two keys

    - by bertsisterwanda
    I am doing a query to return all users shopping carts, stored in the sb_carts table. The product information stored in sb_carts is referenced over two keys product_sku and school_id. It needs to reference both to return a unique product with unique stock levels etc. When I execute the following query it returns one row, I am expecting 3 rows. I have tried breaking the inner join into two separate joins but this still returns only 1 result. joining only on one key has the desired result, but may be retuning the wrong product. A left join returns 3 rows but some data is missing product specific Here is a simplified example of what I am doing SELECT sb_carts.product_sku FROM sb_carts INNER JOIN sb_products ON sb_products.sku = sb_carts.product_sku AND sb_products.school_id = sb_carts.school_id WHERE sb_carts.order_id = 0 AND sb_carts.user_id = 2 GROUP BY sb_carts.cart_id
