Developing a multiplayer AIR based Andoid game and need to save high scores. I was considering using local shared objects to save the scores on the server app but after reading the documentation was wondering if remote shared objects might also work.
Can anyone tell me if I MUST use flash media server to use remote shared objects?
Perhaps even my choice of the socket server class is the wrong approach.
What are you using to develop the AIR game? I am using Flash Professional with a code editor separate for as3. You do not need to use flash media server.
I am using Electroserver through Amazon EC2 cloud servers. Electroserver basically builds into as3 the shell of a multiplayer game(rooms, zones, message system).
Socket servers are the way to go though. Electroserver is socket server too.

Quick bit of advice if i may. I'm a startup company and developing a new mobile app that i intend to query and update data from a cloud MYSQL database, using a restful webservice and JSON. I am pretty new to this, but ok on the theory.
I originally thought i could use Dropbox to host the database and somehow install a Tomcat server also, to act as the http server, but i cant find anything online that says this is achievable. I've now found a temporary site heliohost.org, which offers free hosting, so i'm looking into that.
Does anyone have advice on a [low cost] longer term production cloud service for MYSQL database? And am i right that a good approach is to create a restful webservice in Eclipse and then somehow deploy that to the Tomcat server in the cloud, so that my app can then issue calls to it via the CN1 available methods.
There is quite a lot out there and much of it is self-promoting their own sites so was after some independent advice please.
Many thanks in advance.
You can't host and access an SQL server over the network from a device as access is remarkably unreliable and insecure. You will need some form of hosting. I used Linode for our online course since they are very affordable (5USD per month) but I've used AWS, Digital Ocean and others. They are all good.
You are correct that you will need to create a webservice, I used tomcat in the past but for the latest course I chose SpingBoot which is easier and more modern.
Using a mobile backend to store and retrieve data is a vast topic to discuss where different tools and services can be leveraged based on your application use cases.
However directly accessing MySQL server from your mobile client wouldn't be a recommended approach both in term of security as well as performance at scale.
Few options you can consider.
Developing the mobile backend with Amazon Mobile Hub where you can find different architectures and services. For example.
Using AWS DynamoDB as a Mobile Backend tightly controlling access permissions with AWS Cognito and DynamoDB Fine Grained Access Control.
Using Cognito Sync as a storage medium to Synchronize data from Mobile App to AWS and then using triggers to share and push data & etc.
Developing a REST API for the mobile backend using AWS Services such as API Gateway, Lambda & DynamoDB(Or Relational Databases like MySQL, Postgres SQL & etc. with RDS)
I'm currently doing a iOS application for school to connect to school mysql database.
It should be able to connect to it through the tools on xamarin studio.
I tried a lot of different coding to connect the database, but was unable to do so.
Is there any tutorial or example code to let me learn on how to do it ?
Thanks for any help!
Do not connect directly to a database from a mobile app. Doing this requires exposing your database server directly to the web, which is a horrible security risk. The better approach is to use a web services layer to broker the interaction between your client and your server.
http://docs.xamarin.com/guides/cross-platform/application_fundamentals/web_services/
While people are right and the best way to connect to a database is to use a web service there are some times you want to connect directly and ways to make the connection more secure (ip restrictions on the mysql server).
Here is a plugin with code examples on how to do it:
https://components.xamarin.com/view/mysql-plugin
Be sure to pay attention to the first forum question on errors and how to resolve. You need to include a reference to system.data, I18N, I18N.West in your project and also make a call to the constructor for I18N somewhere in your code.
new I18N.West.CP1250();
I have to develop an application which will run server and and access through Remote connection to multiple user, is normal application is accessible to multiple user at the same time or we have to make some effort .
We are thinking to use technologies are
1: java swing and hibernate for persistence layer , as its single desktop application , so does we need to add server to give access to multiple user at the same time.
Thanks in advance.
trying to migrate my existing asp.net website which is using mysql to Windows Azure.
I have a few questions
How do i host my existing asp.net application in Windows Azure?
Any good links to recommend for a beginner?
Is it a must to create a windows azure application in order to host my existing website in Azure?
Is it true that mysql will cost $0.12 an hour per web role?
Hosting asp.net applications in Windows Azure is a broad subject. I suggest starting with a tutorial such as this one for initial intro: http://www.asp.net/mvc/tutorials/deployment-to-windows-azure/walkthrough-hosting-an-aspnet-mvc-application-on-windows-azure
Simplest would be to add your existing ASP.NET project as a Web Role to a new Azure project. (Tutorial link above explains how this can be done)
MySQL is not supported in Windows Azure at this time. I suggest either switching to SQL Azure (prices here) or you will need to host MySQL instance elsewhere and connect to it from Azure servers (not recommended due to latency). Installing MySQL on a Windows Azure instances is totally not recommended, since those instances are stateless and Azure can choose to re-image them at any time. (Unless you have a read-only MySQL database and have a way to auto-install it via a setup script)
HTH
One thing to keep in mind, ASP.NET Sites are not supported, it has to be an application. You can see this link for how to convert to an application if needed:

I'm attempting to write a Windows Phone 7 application which needs to connect to a remote data source, in this case it's a MySQL database on a Linux server. I'm not able to move this over to MSSQL, nor to build any kind of windows-based solution (like a WCF web service on the server).
Is there a way for me to use my MySQL database from my Windows Phone 7 application? The MySQL assemblies don't seem to work on the phone. If not, what would the best solution for me to use this database from the phone?
You could build your self a service which would send you json or xml. this can easily be built using mono, python, Ruby, php or any technology that you are comfortable with.
You can build it in a restful manner where all you have to do is call urls in a HTTP GET to retreive data which you handle with the services.
and use the HTTP POST to submit changes to your service.
you can then from WP7 make calls to this service and consume the data.
WP7 does not support sockets at the moment. So your best bet is transfering your payloads over HTTP.
As I mentioned before, if you have access to the machines configuration. You could run Mono which isn't too far off of .Net in terms of language and functionality.
further more, from the phone you can use the Rx library to make these calls Async and keep your application responsive.
