Ummm... oookaaay... you can do that with ADO.net; I generally write utilities that take command-line parameters, like what database to connect to, what table to query, etc.
What are you trying to accomplish?

Do You know how to access list by name?
|
|
|
|
|
What list? The worksheet name? The column name?
|
|
|
|
|
This is worksheet, sorry.

Your excelapp/workbook will have a collection of worksheets which you can iterate.

I know, but I need to refer to the worksheets by name.
How I can do it?
|
|
|
|
|
I'm pretty sure the indexer will accept a string as well as an integer Workbook.Worksheet["SheetName"]

Could you show an example refer to worksheet and search for an arbitrary column? Because I never did it. If you can. Thanks.

bonjour, 
"""pour le moment je suis entrain de développer une application qui enregistre le son( sous forme numérique) entré par une carte électronique dés le port // .alors j'ai qlq questions a vous posé .
1) comment enregistrer du son qui va être sous forme numérique avec une application c # sur une base de données (sql server) ?
2 ) aussi comment lire ce son enregistrer (Sous forme numérique) dés la base de données ???
merci d'avance"""""

Je suis désolé, mais c'est un site anglophone. Vous allez vous tenir plus de chance d'obtenir une réponse si vous traduisez votre question en anglais.

""" "for now I am trying to develop an application that records audio (digital form) entered into an electronic card dice / / port. so I QLQ questions you asked.
1) how to record sound which will be in digital form with a C # implementation of a database (sql server)?

thank's man don't worry i speak english too

Je ne habbello Francais. You'll find that the documentation is in English, the community is English, and that hence, the preferred language is English.
What do you want help with exactly? Recording sounds as binary, saving binary to a database, or the whole shebang?

Thank's sir for your answer
by the way the sound that will enter by the Parallel Port as Digital Data so i wanna saving binary to a database with c sharp application .
how can i do that ??

Direct communication with a port is prohibited under Windows, you'd need a driver to talk to. We got an article[^] on that, of course.
The hard part won't be fetching the data, nor writing the data to some database. The hard part will be to transform those bits to some music-format, like wav or mp3. No, that's not a trivial task, and is usually done by the drivers of the sound card. Our applications usually speak with those drivers, using Windows' API, not with the machine directly.
If you're going to speak to some machine, you'll have to be able to speak it's language - meaning that there's a manual somewhere explaining how the data that you're receiving is encoded.

yes sir ,
I could read and write to the parallel port with c # but the problem is that I'll connect the parallel port card with my carte electronic of its digital form I know not in what form I will record this with C # in the Database .
if you could help me.

I cannot help; only the manufacturer of the device can tell you how it encodes it's audio, and thus, how you should decode it.

it's me the manufacturer of the device lol

|

Then you will be the only one who can tell how the hardware will encode the data, and "what" the device will be sending to that port.

A sound in binary form is just a byte stream. You can use a BLOB database column to store it, with some kind of ID or name as the key.

thank you for your help,
I just just want you to know that the dice are entered by 8bits 8bits Parallel Port successively so how can I Register this with c # application on the database.?

Hello !
Can any one please help me on how to detect a windows change?
What I wish to accomplish is detecting when a user changes from one window to another, for example user has 3 programs running, Internet Explorer, Skype and Notepad, user is Browsing in Internet Explorer and then he changes to skype, when this happens I would like my C# program to detect that change. Is this possible? How can i do this?
Thank you very much

You would have to implement a Windows CBT Hook callback. This will notify you of any changes to the windows, including which one is going to be activated, created, destroyed, ...
