  • Android: Best way/library to write an app that simply gets/sets your Facebook status, sends Facebook

    - by D.
    I have the Android Facebook-Connect library running in my emulator and I'm able to set my status with the Facebook API I have setup. However, I don't know where to go from there? Am I supposed to use the session key that this library allows me to get and make some Facebook API calls? I haven't found any code examples to even see what the proper syntax is. Am I better off using another library? I tried fbrocket with limited luck(I get a "server error 104 - Incorrect signature"). Thanks for any help.

  • Ideas for loading initial data in an iPhone application?

    - by Derek Clarkson
    Hi all, In my app I want to load some initial data to show the user how it works. The app uses a CoreData managed sqllite db. SO far I've thought of 3 options: Write code into a class to programmatically create the data. Create a xml file in the apps resources and load through a NSXmlParser whose delegate creates the entries in the sqllite db. Same as option #2, but use a json file and bring in a 3rd party lib to read it. Are there other options I have not found yet? and given that I'm talking about perhaps 6 records per table when there are 3 tables, which would you choose?

  • How to structure a Visual Studio project for the data access layer

    - by Akk
    I currently have a project that uses various DB access technologies mainly for showcasing or for demos. Currently we have: Namespace App.Data (App.Data.dll) Folder NHibernate Folder EntityFramework Folder LinqToSql The above structure is ok as we only use Sql Server as the DB. But going forward we will be including Oracle, MySql etc. So what would be a better structure with this in mind? I thought about: Namespace App.Data.SqlServer (App.Data.SqlServer.dll) Folder NHibernate Folder EntityFramework Folder LinqToSql Or would it just be better to have separate assemblies for each database and access technology?: Namespace App.Data.SqlServer.NHibernate (App.Data.SqlServer.NHibernate.dll) Namespace App.Data.SqlServer.EntityFramework(App.Data.SqlServer.EntityFramework.dll) Namespace App.Data.Oracle.NHibernate (App.Data.Oracle.NHibernate.dll) Namespace App.Data.MySql.NHibernate (App.Data.MySql.Oracle.dll)

  • Flash in VC++ Documentation

    - by Red Serpent
    Hi I am trying to host a flash object inside an CAxWindow, I have managed to insert a shockwaveflash (SWF) and its working fine. I am trying to find all available API's that are available in the flash ocx. I am unable to find any documentation for the functions in the IShockwaveFlash interface. I know that Adobe doesn't have a documentation for using flash in VC++ but I was wondering if anyone can point me to a place where I can find an UNOFFICIAL documentation for flash.ocx or code samples as the only API that I could find and I'm currently using is "PutMovie". Any help is appreciated...

So far I got this link up http://open.api.ebay.com/shopping?callname=GetMultipleItems&responseencoding=XML&appid=Morcovar-c74b-47c0-954f-463afb69a4b3&siteid=0&version=525&IncludeSelector=ItemSpecifics&ItemID=220617293997,250645537939,230485306218 I've saved the document as .xml file using php curl and now I need to get/extract the values(itemID, title, price and mileage) into arrays and store them in database.

  • What does it take to get the "LyricArtist" from this XML feed using Nokogiri?

    - by fail.
    First the xml: http://api.chartlyrics.com/apiv1.asmx//GetLyric?lyricId=90&lyricCheckSum=9600c891e35f602eb6e1605fb7b5229e doc = Nokogiri::XML(open("http://api.chartlyrics.com/apiv1.asmx//GetLyric?lyricId=90&lyricCheckSum=9600c891e35f602eb6e1605fb7b5229e")) Successfully will grab the document content. After this point i am unable to get inside and grab data and i am not sure why? For example, i would expect: doc.xpath("//LyricArtist") To kick back the artist but it does not. I have tried the same thing with other feeds, such as the default RSS feed that any wordpress installation provides and if i do something like: doc.xpath("//link") I get a list of all the "links". I am definitely missing something and would love your input. thank you!!

  • Why is rails setting ":null => false" on all my columns in schema.rb?

    - by ryeguy
    Even if I never specify :null => false in my migrations that initially add columns to tables, rails still generates code in schema.rb that specifies the columns as having :null => false. Why is this? If I develop on my box, and then use rake db:schema:load on my production box, I'm going to get very different behavior! Edit: Even if I delete schema.rb and run rake db:schema:dump, it still puts :null => false on the new schema even if it isn't defined like that in the actual database. It seems it can't tell whether or not a column is marked as allowing nulls. I'm using SQLite if that helps.

  • Having difficulty catching postgresql exception in sequel/ruby

    - by mhd
    I have postgresql table that has somekind of unique constraint. I have ruby script that will update this table. The ruby script should be able to switch to UPDATE instead of INSERT when this kind of error occured: PGError: ERROR: duplicate key value violates unique constraint CMIIW, sequel seems cannot catch this exception?? Anyway,sample code below is something that I would like to see to work but apparently not: @myarray.each do |x| fresh_ds = DB["INSERT INTO mytable (id, col_foo) values ('#{x}' ,'#{myhash[x]}')"] result = fresh_ds.insert catch Sequel::Error do fresh_ds = DB["UPDATE mytable set col_foo = '#{myhash[x]} where id = #{x}"] result = fresh_ds.update end end Maybe my ruby code is wrong or I missed something I don't know. Any solution? Thanks. UPDATE: code below works, the error is caught when unique constraint is violated. @myarray.each do |x| begin # INSERT CODE rescue Sequel::Error # UPDATE CODE end end

  • Python and sqlite3 - importing and exporting databases

    - by JPC
    I'm trying to write a script to import a database file. I wrote the script to export the file like so: import sqlite3 con = sqlite3.connect('../sqlite.db') with open('../dump.sql', 'w') as f: for line in con.iterdump(): f.write('%s\n' % line) Now I want to be able to import that database. I tried: import sqlite3 con = sqlite3.connect('../sqlite.db') f = open('../dump.sql','r') str = f.read() con.execute(str) but I'm not allowed to execute more than one statement. Is there a way to get it to run a .sql script directly?

  • Would using a MemoryMappedFile for IPC across AppDomains be faster than WCF/named pipes?

    - by Morten Mertner
    Context: I am loading and executing untrusted code in a separate AppDomain and am currently communicating between the two using WCF (using named pipes as the underlying transport). I am exchanging relatively simple object graphs using a reasonably coarse-grained API, but would like to use a more fine-grained API if it does not cost me performance-wise. I've noticed that 4.0 adds a MemoryMappedFile class (which doesn't need a physical file, so could be entirely memory based). What kind of performance gains could I expect to see (if any) by using this new class? I know that it would take some "infrastructure code" to get the request/response behavior of WCF, but for now I'm only interested in the performance difference.

  • ORM on which standards i can select?

    - by just_name
    Q: This question is about how can i figure or select the convenient ORM to my web application. when beginning a new web application,What are the criteria on which i can consider a specific ORM is better than another one for my project or case(web application)? another part of my question : when i begin any web application i use three layers: the DB layer (which contains the connections , and handle the CRUD operations ) the Managers layer(the Data Access Layer) a class for each table on my db (loosely coupled with the previous layer )it contains the CRUD operations for the specific table and the other required operations. the interface layer.. and i use Object Data source.Is that considered as an ORM (as a concept) or I'm wrong in understanding this concept. note:I still a beginner in this field ,, and every day i learn more about web development. please i want explanation and suggestions for this point. Thanks in advance.

  • Using IPrinciple.Identity.Name as a key in a dataBase to identify user's rows.

    - by bplus
    I'm writing a small intranet app that uses Windows Authentication and Asp.Net MVC. I need to store various bits of data in a db against each user. As far as I can tell the IPrinciple object does not seem to have something like a unique id. So I was thinking I could just use User.Identity.Name as a unique value to identify rows in my db. Is this a bad idea? Is there an alternative to this approach? Thanks for any help.

  • Excel Add-in memory explosion

    - by tsinik
    I wrote a small .NET add in to excel 2007 that read data from external c++ api and display it inside an excel. The task manager shows that I'm having a memory leak (the memory usage is inflate linearly up to 250MB after whitch it throws an "Excel cannot complete this task with available resources error") but the problem disappears as soon as I minimize the excel window. The api uses delegates to return data and I update it into a dictionary. another thread is updating the excel from the dictionary every second. It is unlikely that the unmanaged code is responsible of the leak. Does anybody have an idea what can cause this? 10x!

  • Updating Many-to-Many relationship with LinqToSQL

    - by Noffie
    If I had, for example, a Many-to-Many mapping table called "RolesToUsers" between a Users and an Roles table, here is how I do it: // DataContext is db, usr is a User entity // newUserRolesMappings is a collection with the desired new mappings, probably // derived by looking at selections in a checkbox list of Roles on a User Edit page db.RolesToUsers.DeleteAllOnSubmit(usr.RolesToUsers); usr.RolesToUsers.Clear(); usr.RolesToUsers.AddRange(newUserRolesMappings); I used the SQL profiler once, and this seems to generate very intelligent SQL - it will only drop the rows which are no longer in the mapping relationship, and only add rows which did not already exist in the relationship. It doesn't blindly do a complete clearing and re-construction of the relationship, as I thought it would. The internet is surprisingly quiet on the subject, and the query "LinqToSQL many-to-many" mostly just turns up articles about how the LinqToSQL data mapper doesn't "support" it very well. How does everyone else update many-to-many with LinqToSQL?

  • How to add .Net3.5 dll into .Net2.0 project?

    - by macias
    I have a dll which is based on .net 3.5 -- it uses internally for example Linq, but the exposed API is straightforward, no fancy stuff. Since C# generics are resolved at compile time I assume that for calling party all it counts is API (all public parts). However when I try to use this dll from net2.0 project I get info, that the dll cannot be referenced because the dll or one of its dependencies requires a later version of .net framework. I can install any .net version I want on target computer (when entire app is installed), but I cannot change .net version for the project itself. So: how to solve this? When adding a C dll to this project I had no such problems, so are C# dlls self-contained or not?

  • How to get the stream of a public Facebook fanpage in php?

    - by Bundy
    Hi, I want to display my public fanpage feed onto my website via the Facebook API without requiring a login. I'm doing this require_once('../includes/classes/facebook-platform/php/facebook.php'); $fb = new Facebook($api_key, $secret); $fb->api_client->stream_get('',$app_id,'0','0','','','','','')); But I get this error Fatal error: Uncaught exception 'FacebookRestClientException' with message 'user id parameter or session key required' in includes/classes/facebook-platform/php/facebookapi_php5_restlib.php:3065 Stack trace: #0 includes/classes/facebook-platform/php/facebookapi_php5_restlib.php(1915): FacebookRestClient->call_method('facebook.stream...', Array) #1 facebook/api.php(12): FacebookRestClient->stream_get('', 13156929019, '0', '0', 30, '', '', '', '') #2 {main} thrown in includes/classes/facebook-platform/php/facebookapi_php5_restlib.php on line 3065 Then I figured, because of 'user id parameter or session key required', to add my user id to the call require_once('../includes/classes/facebook-platform/php/facebook.php'); $fb = new Facebook($api_key, $secret); $fb->api_client->stream_get(502945616,13156929019,$app_id,'0','0','','','','','')); But then I got this error Fatal error: Uncaught exception 'FacebookRestClientException' with message 'Session key invalid or no longer valid' I'm totally clueless :)

  • Compiling SQLite into programs that run on Symbian 9.1 and above?

    - by Jared
    How can I use SQLite C API’s on any device running Symbian OS 9.1 or above? While it appears that 9.4 comes with SQLite built in prior versions do not. Looking at http://sourceforge.net/projects/sqlites60/ it appears that sQLite has been ported to older Symbian releases. The only problem is this code assumes you want to use SQLite with .net when I want to compile it into a .sis file and call the C API’s. Ideally I’d compile a Symbian equivalent of amalgamation.c and call the sQLite functions directly but am not sure if this is possible.

  • How to tell if running in a linux console versus an ssh session?

    - by Stéphane
    I have an application that needs to behave differently if run directly from the linux console. So if a user connects with SSH to run FooBar, or the user walks over to the console and logs in directly to run FooBar, I want it to do something different. What C API do I need to call to tell the difference between these two scenarios? I was thinking I'd have to look at the "tty/pts" information (such as what I see when I run "ps axf"), but I'm not certain if that is the best solution, nor what API to call to get that information. Hints appreciated. :)

  • SQLite/iPhone read copyright symbol

    - by Marco A
    Hi All, I am having problems reading the copyright symbol from a sqlite db that I have for my App that I am developing. I import the information manually, ie, from an excel sheet. I have tried two ways of doing it and failed with both: 1) Tried replacing the copyright symbol with "\u00ae" (unicode combination) within excel and then importing the modified file. - Result: I get the combination of \u00ae as a part of the string, it doesnt detect the unicode combination. 2) Tried leaving as it is. Importing the excel with the copyright symbol. - Result: I get a symbol that is different from the copyright, its something like an AE put together.looks like this: Æ Heres my code how I read from DB: -(void) readCategoriesFromDatabase:(NSString *) rest_input { // Init the products Array categories = [[NSMutableArray alloc] init]; // Open the database from the users filessytem rest_input = [rest_input stringByAppendingString:@"'"]; NSString *newString; newString = [@"select distinct category from food where restaurant='" stringByAppendingString:rest_input]; const char *cat_sqlStatement = [newString UTF8String]; sqlite3_stmt *cat_compiledStatement; if(sqlite3_prepare_v2(database, cat_sqlStatement, -1, &cat_compiledStatement, NULL) == SQLITE_OK) { // Loop through the results and add them to the feeds array while(sqlite3_step(cat_compiledStatement) == SQLITE_ROW) { NSString *catName = [NSString stringWithUTF8String:(char *)sqlite3_column_text(cat_compiledStatement,0)]; // Create a new product object with the data from the database Product *category = [[Product alloc] initWithName:catName]; // Add the product object to the respective Array [categories addObject:category]; [category release]; } sqlite3_finalize(cat_compiledStatement); } NSLog(@"Finished Accessing Database to gather Categories...."); } I open the DB with this function: -(void) checkAndCreateDatabase{ NSLog(@"Checking/Creating Database...."); NSFileManager *fileManager = [NSFileManager defaultManager]; success = [fileManager fileExistsAtPath:databasePath]; [fileManager removeFileAtPath:databasePath handler:nil]; NSString *databasePathFromApp = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:databaseName]; [fileManager copyItemAtPath:databasePathFromApp toPath:databasePath error:nil]; [fileManager release]; if (sqlite3_open([databasePath UTF8String], &database) != SQLITE_OK) { sqlite3_close(database); database = nil; } NSLog(@"Finished Checking/Creating Database...."); } Thanks to anything that can help me out.

  • As a team should we develop locally and merge into the dev server, or develop on the dev server?

    - by CogitoErgoSum
    Hey, Recently I was tasked with writing up formal procedures for a team based development enviroment. We have several projects with multiple modules each. Right now there are only two programmers, however there are plans to expand to 4-6 programmers. Each programmer will be working on the same project and possibly pages which may cause over writing or error issues. So far the ideal solution I have thought up is: Local development (WAMP/VM or some virtual server instance on their own machine). Once a developer has finished their developments, they check it into the CVS Repository and merge it wih other fixes etc. The CVS version is then deployed to the primary dev server for testing by the devs. The MySQL DAtabases are kept on the primary dev server and users may remotely connect to it. Any Schema / Data alterations are run through a DB Admin who will notify all devs of any DB Changes (Which should be rare). Does anyone see an issue with this or have a better solution?
