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?

Telnet Library

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.

Problems with DataRowState.Modified

polishprogrammer12-Apr-07 7:36

12-Apr-07 7:36

I'm looking to allow the user to make changes to a database. Basically, I have a DataGridView and a bunch of text boxes to allow the user to view all relevant fields on the DataGridView on one form. Both the text boxes and the DataGridView are bound to a DataTable and to a BindingManagerBase.

I want the user to be able to make multiple edits to the database and then click 'Save' to save any and all changes he/she has made since the last time the database was saved. I'm filtering the rows by DataRowState and only updating those rows that are DataRowState.Modified. Well, this works OK, except that if the user is editing the row he is currently viewing, it seems the data is not validated as being part of the DataTable, so the row is not considered Modified. If the user switches rows to an unedited row prior to clicking 'Save', then all changes are saved, but forcing a user to do that is not ideal, to say the least.

Any feedback would be appreciated. Thanks.

Hi.

What do you think about J#?
Have you ever done any important project using J#? Why should(n't) we use it? Is it worth any attention at all?
It's one of just 4 official .NET languages and yet Code Project doesn't have a forum dedicated to it.
Is J# just a big waste of time and money from Microsoft in order to feed their fat ego?

Don't use it. Microsoft is dropping support for J#[^].

J# was created to make it easier to port from java .net. While it might've been used a fair amount in that role back in 02 by people who originally wrote their apps in j++ before sun killed it, no one's using it anymore so MS has decided to stop developing it.

Hi, I have been looking for a simple, free, forum software download I can use. I have had problems with "Yet another forum" and "Jumpy Forum". My preference would be a .NET 1.1 or 2.0 (even better) application in C#. I've scoured the Internet, but no luck so far. Could anybody please recommend one?

Thanks

Outlook email text ignores \r\n

Hi!

I am trying to creat the body for an email. First I create the text of the email like this:

System.Text.StringBuilder sbBody = new System.Text.StringBuilder();
sbBody.Append(" asdasfsdgfdfg dfgh \r\n");
sbBody.Append("fw4 34wtrc345v345345gv43bv3 \r\n");
sbBody.Append("asdasdaskjfn39i4fn3498gn4oegerlkg. \r\n");

Then I start a process that launches the email client. The problem is that the text of the email is not displayed correctly in Outlook, meaning that the \r\n are ignored(if I display the text in a message box the \r\n work fine). Can anyone help me with this problem...

PS: I have tried using Convert.toChar(13) but still nothing...

If it's in HTML view, \r\n won't have any effect. You'd need a <br /> tag there instead.

I have tried adding <BR> instead of \r\n...but in this case it just displays <BR> in the text...this means that it is not in HTML view mode

I wrote a code project article on this:

The short answer is log on to the network sever, go to the computer management then shared folders then open files.

By the way I like the reference to Romans 12:21

Hope that helps.

On the machine with the share, right-click MyComputer, click Manage. Under System Tools, open Shared Folders. It should be obvious from there.
