Eclipse can't connect database - database

Is it possible to build desktop application whit small data base on linux/ubuntu? I have try eclipse+derby- not work, driver load, but can't connect to db. Eclipse +sqlite- not work too, No suitable driver. For a week from now i trying and can't connect to my db. If some1 have WORKING tutorial how to do this in ubuntu+eclipse, pls share. 1 week google, so please if some1 pass this to help me.
Now im using SQLite, i have load the sqlitejdbc-v051.jar in build path and use
Class.forName("org.sqlite.JDBC").newInstance();
but the result is: No suitable driver found for jdbc:derby:/home/vasil/MYDB

Have you taken a look at this site? It seems to be a fairly decent walkthrough. Is the db server that you are trying to connect to running and somewhere accessible to your application?
Take a look at this question. It seems to be very similar to yours. I havn't used derby but I have used many other db servers. It sounds like you dont have the driver on your applications classpath.
Also, this tutorial might also be helpful. It shows how to use jdbc to connect to a db.

Server communication with database

I'm creating an online game and the client is going to be made using unity as well as the server and I'm wondering whether it's okay for the server to communicate with mysql database via PHP
For simple tasks, there is actually nothing wrong with that.
There is also a example of using this method in the wiki here: http://wiki.unity3d.com/index.php?title=Server_Side_Highscores
But be aware: that is not the fastest solution.
You could make a faster direct connection with a plugin like this one:

And for native unity support on Android and iOS support i would go with a sqlite database plugin: https://github.com/rizasif/sqlite-unity-plugin

QuickBooks connection using asp

May not be the best place to ask sorry if that's true.
I have worked on SQL and while I never worked on QuickBooks I am hoping it is possible to connect to it and just use it similar to a SQL Database. I am wondering I am wondering if it is possible to connect to QuickBooks using ASP. My purpose is to create simple forms and insert the data into QuickBooks similar to what is done on SQL.Occasionally I would just generate reports as well using web pages. All I am wondering is does ASP have the capability to connect to Quick Books and if so can I also run query's similar to SQL and is there any sources or reference available for research ? And what my options are for setting this up. If I have to use asp.net as a last resort that is fine too, though I would prefer to have to be without it.
Thank you
Update #1
While i am working on getting the Version of Quick-Books here is what information I have.
I plan on using ASP-Classic, and I want to develop web forms so this would be a website that can be accessed. This will not be a desktop application I plan on making but various webpage's where you can view Quick-books data, and insert records into Quick-books using forms, similar to what I do for SQL. And the Version of our Quick-Books is 2013 Enterprise Windows Desktop USA edition.
All I am wondering is does ASP have the capability to connect to Quick Books
Yes.
can I also run query's similar to SQL
Maybe.
QuickBooks itself does not provide an SQL-based interface. Communication with QuickBooks is via XML. However, QuickBooks Enterprise comes with something called QODBC which provides an ODBC interface to the XML interface QuickBooks provides, which might get you what you need.
One problem you want to watch out for -- there are times when you won't be able to connect to QuickBooks. e.g. it is not an "always-on" solution like a typical SQL database is. If you're in single-user mode in QuickBooks, or someone closes QuickBooks, or someone is doing a QuickBooks backup, or someone is updating QuickBooks, then you won't be able to connect. You'll have to plan for this in your application.
A better solution might be to use the QuickBooks SDK (specifically the QuickBooks Web Connector). If you download and install the SDK there is example code included. The SDK install also includes about 600 pages of PDF documentation on topics which you are asking about.
Striking out the below stuff since you've provided more details now: But unfortunately you didn't provide anywhere near enough information for anyone to actually give you a decent answer.
How about providing some actual details so that people can actually help you? Like, maybe:
Is this QuickBooks ONLINE, or QuickBooks for WINDOWS, or QuickBooks for MAC? (they are three entirely separate products, with entirely separate sets of capabilities)
What version/year/edition/country of QuickBooks?
ASP classic or ASP.NET?
Is this a website you're connecting from, or is this a desktop application, or...?

Update a local/client Microsoft Access Database from a server (MS SQL Server2005)

I've got a website that runs on a shared hosting environment, using ASP.net 2.0 (C#) and MS SQL Server 2005. I've recently been asked if I can integrate my website with a piece of third party desktop software that uses the Access runtime as its database (transparent to the end user).
Primarily I want to be able to offer users of my website the option of exporting their data into the Access database on their local machine. The data schema's match sufficiently, the question is how to actually do this, and in the simplest way possible for the user.
Simply having a webpage update the local Access database isn't possible due to the obvious security restrictions. I've considered asking them to upload the Access database to the server, so I can migrate the data then allow them to download it again, however the competency of the users of this software is such that even locating the Access database, let alone uploading and downloading it from the website might be too complicated.
I've also considered if Adobe Air or Silverlight could help here, but don't know them well enough to know for sure. Similarly I'm assuming another exe could be written to perform this task that the user could simply download and run, however my experience is in web development, not program development, so this isn't a 100% certainty for me, or an ideal development option for me.
So, can this be done, and if so what technique can achieve this, with the stated aims being ease of use for the end user, followed by ease of development by someone with web development as their main skill. Many thanks!
You may find this answer of interest: Best way to stream files in ASP.NET
It is about transferring a file from the server. You could save Excel or CSV and use that to update Access.
Instead of trying to do this in a web page you might just expose some views from your sql server to some client specific logins.
Then within the Access application, allow them to tie to your sql server. You might even provide an access application for getting the data from your site and stuffing it in their local access database.
In my work we have done something similar that is transparent to the user by creating an ActiveX control. The problem is that you are limiting the users to use only Internet Explorer.
I think that the best way to achieve what you are trying to do is by installing a service in the client's computer. If creating a service is beyond your experience you can post a project in a place like oDesk and find somebody that can help you with the development for the money that you are willing to pay to complete your project.
Good Luck.

Any Good Examples of Mobile Sync Framework Solutions

We are investigating using the Microsoft Mobile Sync Framework and I would like to put together a quick prototype. I am trying to pitch Mobile Sync Framework ofer another sync provider. I have zero experience with it so far, so I am looking for good examples of how to use it to sync backend relational database to SQL Server Compact database to enable working in an offline scenario. It would be very helpful to see a sample syncing solution with Oracle as the back end, but Sql Server should be fine to get an understanding.
Thanks,
Tom
Have you checked out Oracle Database Lite?
It includes a full sync solution for mobile devices, and is (obviously) compatible with an Oracle back end.
You can download it here:
http://www.oracle.com/technetwork/database/database-lite/downloads/index.html
The download includes full documentation and several source code examples.
see here: Sync Framework Resources Hope that thread helps
For an end to end solution for syncing between a mobile device and a server, have a look at the SyncComm project
Also this article from syncguru should give you a head start on writing your own provider for Oracle - it's quite straightforward to plug said provider into SyncComm - but I can if needs be provide further guidance.

Winforms: Write app.settings during Setup

I've battled with modifying Configuration settings in the App.config file in the past, and gave up any hope of making it work. Now again, I find myself in the same shoes, but this time determined to sort it out!
The application Im creating is a WindowsForms .NET 3.5 (SP1) app. It is to be used in a closed, networked environment. It is not a SmartClient app, but an "always-connected" one, and transacts over the local network with a central database server.
The app works fine, and now that Im ready to deploy and create the setup files, I must ask 2 very important questions:
How do I (especially!) 'modify' the ConnectionString value from the Setup Wizards? ;and
How/where do/should I encrypt this value?
This is surely something every developer goes thru when moving from development to production, and I would sincerely appreciate any help.
Thank you!
This question provides good information on how to modify the configuration file (in general) during setup.
