You need to put the PC name into the connection string in place of (local).

Thanks. I use below conection string, but there's appear error in remote connection.
On same pc connection is OK.
mConnection = new SqlConnection(@"data source=servername\sqlexpress;" +
"database=databasename;" +
"UID=user;PWD=pass;");
Error mesage is:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
Server Authentication is SQL Server and Windows Authentication mode.
Allow remote connections to this server is set.
What may cause this mistake?

By default, Sql Server 2005 blocks remote connections. This is an intentional security measure that you can override. Just set Sql Server to accept remote connections.

I realize this is technically a general .net question, but since this form gets many times more traffic than the .net Framework one, forgive me for thinking I have a better chance of getting an answer here. (Besides, I'll be implementing it in C# anyway)
Simple Question: Using a basic TabControl, is there any way I can get the tabs to render (and respond to clicks! That's an important bit...) centered?
More Complex Version: The centering thing above is just an example, and actually not what I want to do, but it would demonstrate the behavior that I want, which is to be able to offset the tabs from corner of the tab control by a certain pixel amount to make room for additional buttons (like a Mozilla-style drop-down). An even better question still may be, Do I have any control whatsoever over the rectangle that the tabs draw in, or the tab rectangles themselves? Please note that I would like to use the basic TabControl if at all possible.
Thank you!

For an ASP.NET app, you should look into using the following server control
<br />
<asp:FileUpload runat=server /><br />
Here is a link that tells more about using it...

There is a new FileUpload server control provided in ASP.NET 2.0 which allows you to browse to the file location.

Modify your post and check the "Ignore HTML tags in this message (good for code snippets)" checkbox at the bottom so we can all see the xml.

Load the XML into a XmlDocument, use the SelectSingleNode to select the userid node and change its value via an appropriate property of the XmlNode instance returned by SelectSingleNode. Take a look at the documentation of the mentioned classes and method and the continuative links. Their are many examples and personally I think their use is straightforward.

Load it into an XmlDocument and use XPath to find/replace the value.

OK, this is obscure.
I've got a remoting service that creates a form, and I've got remoting client that needs to hide and show the form. Calling Show or Hide occasionally never returns.
I've verified that that thread ID is the same that created the form and is now calling Show/Hide on the remote server. Though I'm wondering if that's a problem.
BTW, the Form was created with a factory method, so we're not dealing with Singleton or SingleCall lifetime issues, though we may be dealing with lifetime issues for other reasons. Hmmm.
Anyways...anyone have even a clue what might be the problem?
Thanks!

I'm not sure I understand: the .NET remoting server creates the form and sends that to the client?
In any case, my guess is either your service object lifetime is expired, you're talking to the form on the wrong thread, or the form was created on an MTA thread.

This is my problem:
I have these classes:
public Class C<br />
{<br />
<br />
}<br />
<br />
public abstract Class A<br />
{<br />
protected C;<br />
}<br />
<br />
public Class D : C<br />
{<br />
}<br />
<br />
public Class B : A<br />
{<br />
private D;<br />
}
When I do this: B = new B();, I have D AND C in B.
And I need ONLY ONE, which is the newer one - D.
How can I make the Class A use the new one (D) insted of the old one?

Does anyone knows where I can find a free telnet library for C#? I meant a complete source in which I can use methods as connect(), sendData() or disconnect(), for example.
I need to establish communication with a server.
Thanks!

Thanks Dave.
I've been in every result that google give. The problem is that many of them are incomplete libraries and others are extremely complicated.
I was wondering if any of you knows or recommends one library in particular.

Only you are going to know if it's extremely complicated or not. You could get recommendations for everything you've already seen. It's probably going to be up to you to just bite the bullet and use one of the complicated ones.
