Referring to this question that's already been answer:
"What is the best local-database solution for WPF applications?"
What is currently my best choice of local database for my program? Currently I am using XML that is automatically created on the computer when the user run my executable for the first time or when the XML is missing.
I am perfectly fine on using XMLs, users of my application would not be required to install any software other than my application and I can do exactly with it, but my problem is with searching.
My application includes a database (the XML) of all their songs in their music library, and of course each track has its own information and search through each track is really slow! since it's a music library, one user can have at least 1000 tracks or more and searching through it is really really terrible.
I am familiar on using SQL database, (i don't know the proper term for it) but one for online database, I use XAMPP and read the database on a website on PHP. And i really like it. So..
Basically, I am looking for a good local-database solution, where user's won't to download and install any other software (but I am okay, if i would have to include a certain dll to my exe in other to run), and also one that is lightweight and fast in terms of searching.
Yes, i've read the included related question as many times as i could for me to understand it myself but i hope someone can explain the advantages and disad of each of them.
No, i am not looking for one that needs to have a server or something in order for it to work
Previous suggestion is correct SQLite will be your best option because WPF operates .NET Framework. It also supports ODBC driver as i recall
I was going to just comment but can't quite yet.
I wouldn't say there's necessarily a 'best' in most cases. In general whatever you go with is unlikely to be that bad of a choice..
Having said that, I could suggest SQLite as an option for you. Lightweight, very fast, certainly good for strictly local-database options.

I'm working on a project in which I have a PostgreSQL database containing various tables and what not. I have a c# application that needs to be able to enter new data/change existing data/ or retrieve data from the database.
My question is, is there some tool/framework that I should be using to make this interaction easier. Currently, we have written a bunch of database helper functions to make various common operations simple in C#, we've written classes that define what a Column and Table are. We have defined data model classes for all the tables in the database as well as defined table classes corresponding to each data model class.
Basically, we written a lot of code just to be able to interface with the database and I feel like there has to be a simpler way. But maybe not! That's why I'm asking.
I saw some people using the Entity Framework but I'm not familiar with it and don't know if it does what I'm looking for. Also, it seemed like it was geared towards MySql and the free PostgreSql tool for it were a bit hacky.
The short answer is: you are probably already doing it the best way with current technologies.
I have tried several ORM solutions and all of them failed to live up to expectations on one level or another. Entity Framework is starting to get mature, but as you already found, the PostgreSQL adapters are essentially hacks since EF is baked for Microsoft SQL at a low level. One of the better ones I have used is Telerik's ORM, but it costs $$$$ and is far from perfect (http://www.telerik.com/data-access).
One to look at is this: https://www.nuget.org/packages/Shaolinq.Postgres.DotConnect/ Note though that is is an early version, I have not used it myself and generally use at your own risk:)
There are some code first and Node.js specific tools out there that are starting to get interesting, but in the end, having some decent reusable data access library and object classes is generally still the best solution for general use.

I asked about this Q format on meta, and the they said that worded correctly, this should be appropriate. This being said, sorry if I still butchered the wording and just in case I'd like to get this across (as was recommended): I'm not looking for opinions on certain things or how they work, rather just the ways it's possible. I don't mean to sound ignorant and I'm truly sorry if I do, it was just suggested to me to say on Meta.
Now for the Q; What just general language at all would be capable of gathering information from public online websites, then putting it in the program where it could be further processed as just any old variable? I'm new to coding and wanted to do this as a little 'introductory' program, to teach myself some new stuff. Problem being, with my idea, I don't even know where to start. Again, I'm not asking for specific ways to do this, I was just curious what languages are capable of doing this at all? I'd prefer to do it in a Visual Studio's language (no preference of which ones), if that's possible.
In short: Are either Visual C#/C++ capable of gathering information online to be further handled within the program? If not, what languages are?
I agree with the comment that this is a complicated first programming task. However, you'll undoubtedly learn something trying it.
If you already had some experience programming in Python, I'd suggest you took a look at http://scrapy.org/doc/ which is a framework (that is, a bunch of classes and other useful tools) which let you write programs to extract information from web pages. Scrapy does let you concentrate on programming by taking care of some of the nasty details involved in parsing web pages.
Another option is to use a javascript framework, maybe something like node.js.
I've done a fair amount of web scraping, and I usually end up using a combination of utilities which clean up web pages and a variety of XSLT processors. I personally find that combination of technology to be easier to deal with; I don't try to use C-family languages until I've basically wrestled the data into shape. But everyone has their own style.
Good luck!

I am still visiting school and will finish my exams next year. Since two years I am working as (the only :-( ) in-house dev for a company providing financial services to Laboratories and doctors. After spending the first year fixing their existing Application and realizing, communicating and agreeing that it won't meet future requirements i rewrote it from scratch. This is my first LOB application.
I needed a "IEnumerable.ToDataTable()" method to do simplify certain things in the Application. I realized that existing solutions wouldn't meet my performance and flexibility requirements, so i came up with a solution based on Dynamically injected IL code myself.
I thought that this might be a good way to contribute to the community, thats why i asked my employer if i may take some of those code and release it under LGPL. They agreed and that's where my first project is:
ModelShredder
Since this is my first OSS project and i am relatively unexperienced with running an OSS project on my own I am asking you for some "best-pratices" and what i can improve on it.
First read this book:
You can download it free of charge here: http://producingoss.com/ There are also some nice screencasts there that may be some use too.
It covers everything you need to know about looking for, contributing to, starting and maintaining an open source project,
It all depends on if you're going to have a team help you or not. It'll be simpler to start doing it yourself if you have the time if for no other reason than you can work out how you want to proceed without worrying about politics.
For a start, any code used as a framework or a library typically needs to be developed to a much higher standard than what you might write for an internal application. This means you need:
Sufficient user and developer docuemtnation;
Unit tests with decent coverage;
A license;
Tagged versions in source control; and
Released binaries and source code with checksums.
Additionally you'll need a method of:
Communicating your project status (release notes, goals, etc); and
A means to allow people to raise and track issues.
Google Code (as just one example) can do pretty much all of this for you.
I would also suggest you register the domain name for your project (typically projectname.org for open source). If the one you want is taken already, you may want to change the project name, particularly as there might be cause for confusion.
The google code pages look pretty good to me. You might want to think about adding a support group on Google Groups.

I am trying to write a Windows Form and ASP.NET C# front-end and MSAccess backend for a pretty small database concept I have.
I have written this application once before in just MSAccess but I now need the app and database to be in different places. I have now figured out (thanks to a StackOverflow user) that ADO will be a bad choice because it has to have a connection open all of the time.
I bought Microsoft ADO.Net 2.0 Step-by-Step and I have read through some of it and understand (I think) the basic concepts at play in ADO.NET. (Datasets and the like)
Where I get confused is the actual implementation. What I want to know is do any of you know of a C# project that has a database backend which is open source that I can go look at the code and see how they did it. I find I learn better that way. The book has a CD with code examples that I may turn to, but I would rather see real code in a real app.
I haven't used this but it looks like it might be a good fit:
http://www.codeproject.com/KB/database/DBaseFactGenerics.aspx
Take a look at the MySQL .net connector. It is the nuts and bolts of how the ADO.net classes talk to the DB engine. ADO.net as a whole does not keep connections open. Certain higher level classes do. Technically the lower level objects such as the connection and command objects are part of ADO.net, but you have a high degree of control over them.
Check CodePlex, they have a ton of .NET projects. I can't think of specific ones that fit your requirements, but you should be able to find something.
www.codeplex.com
I found this post http://www.codeproject.com/KB/database/DatabaseAcessWithAdoNet1.aspx by searching for ADO.NET on the codeproject so I am going to give Chris Porter the answer points. Thanks everyone for the help.

A couple of months ago I've coded a tiny tool that we needed at work for a specific task, and I've decided to share it on CodePlex. It's written in C# and honestly it's not big deal but since it's the first project I've ever built from scratch in that language and with the goal of opening it from the very beginning, one ends getting sort of emotionally attached to it, I mean you'd wish that the people will actually participate, be it criticism, bug reporting, or what have you.
So my question is, what can I do to actually encourage participation, stimulate curiosity or just recieve more feedback about it?
By the way this is the project I'm talking about: http://www.codeplex.com/winxmlcook/
You should:
Promote it where you think it would be relevant (forums,mailing lists etc.). Try not to spam though - it will create a backlash.
continue to provide updates as to create the appearance of an active project until more people pick it up.
Find project leaders, they are the sort of contributors that encourage others to contribute as well.
Blog about it and link to relevant blogs (creating ping-backs). Also leave comments at relevant blog posts.
Basically, your generic Internet marketing tactics ;)
You first have to acquire users by marketing the tool. Once you have users, that naturally means you'll start getting feedback.
One thing I noticed is your project description doesn't sell the project well. For example, type "winxmlcook" into Google, what gets shown is your project description but it's not likely to get someone to click on it.
I know I sound like a broken record constantly posting this book, but just about everything you could ever need to know about running an open source project is here. In particular, pay attention to these two chapters:
Getting Started
Managing Volunteers
