It's just a stream of bytes, like any other file on your hard drive. What the bytes represent does not matter.

Usually you temporarily decrypt the file... play it on any player... then encrypt it when done and get rid of the file. You could decrypt as you go if you make a codec, I believe someone else already suggested that, but that's probably not as common as you might think it is.

I have been developing C# application that is monitoring for employee time(in & out) so i want to add fingerprint so please can some one help me about the finger print code
|

Please, don't ask questions like that!
Make your subject descriptive of your problem: "Help" is not very useful as we already know you need help - or you wouldn't be asking... Perhaps in this case "Fingerprint reading for WinForms" would be better?
Then, give us details: remember that we can't see your screen, access your HDD, or read your mind - so give us all the relevant information. In this case, the make and model of your reader would probably help, as well as what you have tried so far, and what problem you have found.
Just asking "can some one help me about the finger print code" makes it look like you have done nothing yourself and want us to do your job for you. This can annoy a lot of people and isn't likely to get you a good response. Show us you have tried, show us what help you need!
If you get an email telling you that you can catch Swine Flu from tinned pork then just delete it. It's Spam.

If you search through the articles here on Code Project, you'll find quite a few articles on finger print recognition. I'm sure that at least one of them will be able to help you out.
BTW, the ability to search and do your own research is a skill that you really should master if you want to continue as a professional developer.

well said Pete. I wonder how he is going to develop a program if he started his development carrier 10-15 year before. (before the google and code project  )

If you ask me, these kids have it too easy now-a-days! Back in MY day, when I was teaching myself this stuff, I had to go to the library and READ BOOKS. 
|
|
|
|
|
Your library had computer books? Plural?
|
|
|
|
|
Yep! The place I went to was right next door to Macomb County Community College. I taught myself a couple of different flavors of assembly and how processors worked out of that place.

In a C# 2008 windows application, I am getting the following error messages:

There is no code in the appliation to use registry, thus the only thing I think can be wrong is something about the connection string to the database.
Here is the connection string in the database to a sql server 2008 r2 database:
<connectionStrings>
<add name="eConnectionString" connectionString="Data Source=DEV;Initial Catalog=DEVDB;User Id=TESTUSER;Password=xxxxxx;"providerName="System.Data.SqlClient" />
</connectionStrings>
The account that is being used is setup for an applicaiton by using a sql server login. The account also has some kind of rights to windows.
Thus can you tell what how you think I can change the connection string to the database and/or tell me what you think can be wrong?

Oops. Looked like your connection string has not pasted correctly.
In any case, to check your connection string, a very good resource is http://connectionstrings.com[^].
|

What makes you think those are errors? I don't see anything that says those are errors. Trace information...yes. But I have no idea what's generating them as the debugger doesn't normally output registry accesses by your code.
|
|

I am trying to determine what could be causing the registry keys to be open when I have no code form them.
I am thinking the problem can be one of the following:
1.objects are created? would you dispose of all the objects?
2. The connections to the database are linq to sql statements. Is there a way to close all the objects?
3. When I create a linq to sql database object, should I be disposing of each object after it is no longer needed?
|
|
|
|

The first quesiton that should be answered is what is putting those message up?? THEN you can go digging around your code, if necessary.
Youre code doesn't have to do anything with the registry and your final .EXE can still appear to do stuff in there because of how Windows load your .EXE and its dependencies.

Not sure what that means. The URL indicates you are using a SQL Server user to log in.
The application cannot be running with that user because it isn't an OS user. Even if the name is the same it is still a different user.

What happens when you comment out all of the code that accesses the database?
|
|
|
|

I will comment out the code that accesses the database. That way I will see if the application still runs.
So you are saying that the application can be passing a different value to the database?
When I debug the application, the information that is passed to the database is obtained from the app.config.
Is there somehow a way for an account that has sql server authenication to also have access to windows? If so, what kind of an access would that be?

A Windows user can have access to a SQL Server database.
A SQL Server user does not have access to windows.

I wanted ention/ask the following:
1. I did find out that the username and password for both windows and sql server are the same name and value. Basically windows username and password are exactly the same as the sql server login. Could this cause a problem? if so, what would the problem be?
2. Since the value for connecting to the database comes from an app.config file, is there any way to comment out that connection string information and the vale and the application still works? I would think this would be possible if integrated security=true in the app.config file. I would think if integreated security is not set, and a user name and password is supplied, then the sql server login would be true, correct?

Which doesn't mean anything. There are two users, in two different contexts and thus they have different access abilities.

Phrased awkwardly but presumably if you are asking if you can remove the user/pwd from the connection string and user a windows user instead.
If so then yes.

Yes.

I want develop a electricity billing application for my friend academic practical. So I have lot of doubt in sending / receiving sms in c# application. Can anyone help for this. Kindly help me.
thanking you.

Research for some sms providers, that give you a web service interface. It is the most practical/easy way.
|
|
|
|
|
If you have the right sms gateway, you will be able to build an application that can send / receive smses.
