Hi all,

Can anybody tell me how to save & retrieve data from local directory or PC's local disks without using database. Which is the better way to do it..? As the client system doesn't have a database so i need to use an alternative to save data & retrieve it whenever required from the windows application i am trying to develop. I need something like whenever i want to read data i should be in a position to import data & when writing i need to export data.

Thanks in advance,

Have you heard about XML files?

There are a huge number of ways you could do this, including a raw file, CSV, and XML among others, but since you are talking about databases I assume that you need some form of record based storage.

The simplest solution is to use a database - there are several which do not require user installation and which have a small footprint. Have a look at SQLCE and SQLite: both install with your application as small DLL files and allow you to use (nearly) all the features of SQL Server in a single user form in your application. Or, if you are desperate, there is Access/Jet/Ace which can do a good job single user.

If you need multi user access, then you need to bite the bullet and install a "proper" database: Sql Server of MySql as otherwise it gets far too complicated to process youself!

What is Tally Like softwares are using ??
They are using Files, and still it supports Multi User heavily...
You have any Idea ??

@OriginalGriff: Access/Jet/Ace are good options, i want to know how much amount of data can they store in them..? What would be the limitations involved in it..? Will it slow down the process(read/write) if there are more number of data in any of the above mentioned databases.

I believe ACE has a 2GB limit (and Jet is superseded by ACE, it had only a 1GB limit), though to be honest I haven't explored up near that size - I'd move to SQL Server Express long before that because it's unlikely that any one user will want that to himself. (You can use JET/ACE as multiuser but it's a PITA and can cause huge problems, particularly as the record count grows.)

For smaller apps, I normally used SqlCE, but am moving to SqLite as the DB is Android compatible - which is becoming more important to me.

Solution 2

Use XML Files....
You can simply write or read it with DataSets or Tables....
Using XML in C# in the simplest way[^]
or use CSV (Comma Seperated Value) Files....

If you want to save Application Settings or a few values.... Use App.Config in project....

In notepad??? I believe you're talking about text files...

yes...it's a text file only..

Referenced article is useless in this case. It shows only how to append text (without any structure) into existing file, but does not allow to edit/update, etc.
A 3!
