What stancrm has written is correct.

You can use the 'Enabled' property of System.Windows.Forms.Control

Let's first convert it to VB.NET:

strActual = "BAT BALL GOALKEEPER"<br />
intPosition = strActual.IndexOf("BALL")

Now it's very simple to convert it to C#:

strActual = "BAT BALL GOALKEEPER";<br />
intPosition = strActual.IndexOf("BALL");

Note: There is a difference how strings are handled in .NET compared to VB6. The index is zero based, not one based, and IndexOf it returns -1 if the string is not found, not 0.

I found the ADO.NET Core Reference to be really easy to learn from despite being a reference after all. It doesn't target the 2.0 version of the Framework, but allot still applies. I supplemented it by Programming ADO.NET 2.0 Applications Advanced Topics which is also good.

I'd be willing to sell the ADO.NET Core Reference if you're interested.

I use the small tag to make the text a bit smaller than the message body, and some dashes to make a separator. That is one way to do it.

You could always use the Express edition of SQL Server. Otherwise, XML or Access *gasp*. Obviously, use the Framework Crypto classes. Don't try to roll your own.

Don't be so concerned about anyone viewing the information, just make sure that the information they see is useless.

Store the hash code of the passwords, not the passwords themselves. That way the passwords can not be recreated from the stored information. When you verify a password, get the hash code for the entered password and compare against the stored hash code.

You can use for example MD5 to get a hash code for the passwords. (The GetHashCode method of System.String is not suitable for creating a long term hash code, as it may change between versions.)

When to use Application Data

Hi,

I have a problem concerning to application data, how to use and what to store.

I have application reports that are installed during application setup.
Inside my application, the users are able to run the reports and also to create new ones.

Now, I'm installing the reports in Application Data\AllUsers\..., and reports created by users, go to the same folder.

My question is: Is this the correct way to do this?

Should my installed reports go to Program Files\... (Application installation folder), and user created report to Application Data\All Users\...?

Does anyone knows best practices for this problem?

Thanks in advance.
