The project is currently using regular sockets and is passing data between a c# client application to a server written in java. The system requires ssl to be used and I am looking to remove the regular socket layer with ssl. As you can tell from my posting, I am new to this and am trying to get pointed in the right direction by looking at some simple examples.

Not a 100% sure since I am not right there looking at the Java server, but my guess would be to know what the port is coming from the java server and have your C# client app listen/talk to the java server on that particular port. Look around CP for good sockets articles.

You have to use the KeyPressed event handler and change the keypress to what you want.

You should be able to change e.KeyChar, Enter does, it is ascii 13...

Does anyone know what is called when you click this button:
http://davidkean.net/images/helpwindow.jpg
I want to use that help button but don't want to turn max and min off on the title bar.
|
|
|
|

For some unknown reason they have chosen the highly illogical name HelpButton for that. 
You have to turn the minimise and maximise buttons off for the help button to show up.

Yeah see what I want to do is us the help button without turning the min and max buttons off. So I want to link it to another button on my form, thus trying to figure out how it is called.

Yes, you said that in your first post, and I said that it's not possible.

What do you plan to "link", and how do you plan to "link" it?
If you want a button on the title bar you have to place it there yourself. I don't know exactly how to do that, but I fear that you have to send windows messages to the window to create the button and handle the events.

I just want the button some where on my form, does not have to be in the title bar. So when you click on my help button I want the same thing to happen if you push the one in the title bar.

Just make your own button with a question mark image then.

Why even bother with that one when you have another help button on your form?

I have a button currently on my form that says help, that is not the problem the problem is getting that button to react the same way as the on in the title bar... thus allowing me to remove the on from the title bar.
|

How does the help button in the title bar react differently?
If you handle the event for those buttons, just execute the same code, and both buttons will react the same. Or am I wrong?
|
|
|
|
|
The help button in the title bar sets the mouse cursor to a "?" and allows you to click on any control which then brings up a small help window.
I don't know what event to call for that button is the problem.

Dear, Sir and Madam
How to improve performance for the code below?
DataGridView1.DataSource = MyDataTable; //(MyDataTable contains 100,000 rows)
The code above spent About 8-9 seconds that so long.
Thank You.
NOTE: WinForm not WebForm

You're retrieving 100,000 rows and 8 to 9 seconds isn't fast enough for you?? Hint: Retrieve less rows! If you're not doing anything with ALL of those rows, there's no reason to retrieve them, now is there?

Exactly. I don't understand why people want to fetch that much at once, unless it is some kind of coordinate mapping/computing thingee-bobber.
Dave Kreskowiak wrote: 100,000 rows and 8 to 9 seconds
That's on the order of approximately 10k records/second...

MyDataTable get data(rows) from Xml file not from database.
If I use MyDataTable.DefaultView.RowFilter = "xxx",
it will spent time for this process instead.
8 to 9 seconds is not fast enough for me.
Is there any idea to improve performance?

Break up the xml file to smaller files and load the correct one base off whatever RowFilter you are planning on setting.

An XML file is a just a Text file. It takes a LONG time for the DataSet class to load AND PARSE that much stuff. 8 to 9 seconds for a file that big is GOOD. You simply have no choice but to break that file down into smaller chunks, organized how you want it filtered, then load only those files that you need.
There is no other way to speed this up...

No kidding, especially for an XML file. Talk about bitching over spilled milk... If it is such a big deal, then he needs to refactor the problem into a smaller file like kubben recommended.

8-9 seconds that I tell you not include Load AND PARSE Xml file.
DateTime d1 = DateTime.Now;
DataGridView1.DataSource = MyDataTable
DateTime d2 = DateTime.Now;
TimeSpan ts = d2 - d1;
Console.WriteLine(ts);
Thank You.

Then why did you say so?!?

You're not seriously rendering 100,000 rows in a dataGrid, are you?? Is the user even going to look at all of that crap?? You really need to rethink your design, 'cause there is no way to speed up the rendering of 100,000. What does the user need to see?? That is all you should be showing them. I can't think of a single good reason to show a user 100,000 rows of a table...

Cut the amount of data down as Dave has said. Only pull up the data that the user is going to be using at the moment, and 100,000 rows is not going to be the case. Allow the user to filter the rows he/she is going to need.
