Sorry guys i'm a bit of a newbie still... 
But anyways here's my question.
I r multithreading! however it's not looking so good... I'm using a beginInvoke to fire off pings at other machines on my network I'm pulling the names from ldap sychronously. Anyways the question i had was "Are async delegates manged by the threadpool"... I thought i read somewhere that they were indeed managed via the threadpool... So next question is how come when i do something like this "ThreadPool.SetMaxThreads(10,10);" The app still fires off the max threads that the threadpool can manage? I.e. 20-25... Hope someone can shed some light on this.. Lemme know if you would like to see some code if that would help define my question/problem! Thanks in advance for any reply's even if it's stfu noobzor and go read a book!

hi
Dont ever say Urgent again, we dont work for you.
Secondly mybe you can write your code like this
SqlConnection cn=new SqlConnection("database=durdu;user id=sa;pwd=");
SqlDataAdapter cmd=new SqlDataAdapter ("select * from marksheet",cn);
Dataset ds = new Dataset();
DataTable dt=new DataTable();
cmd.Fill(ds);
dt = ds("My_Table");
axPivotTable1.DataSource=(msdatasrc.DataSource)(object)dt;
Remember not to use the Word Urgent here

What benefit would a DataSet be?

You can't cast an object to something that it isn't. You can only cast an object to it's actual class, any of it's base classes, or any of the interfaces that it implements.
C# is type safe, so the object contains information about it's actual type. When you do a cast, you cast the reference, but the object still remains the same type. Therefore, when you cast the DataTable reference to object, you get an object reference pointing to a DataTable object. You can't then cast this to msdatasrc.DataSource, as the actual type of the object does not inherit that class.
If the control can't use a DataTable as data source, you have to copy the data from the DataTable into something that the control can use.
Despite everything, the person most likely to be fooling you next is yourself.

I got this from a chat application here on codeproject, there are other ways. Try to download applications in the site.
String GetIP()
{
String strHostName = Dns.GetHostName();
// Find host by name
IPHostEntry iphostentry = Dns.GetHostByName(strHostName);
// Grab the first IP addresses
String IPStr = "";
foreach (IPAddress ipaddress in iphostentry.AddressList)
{
IPStr = ipaddress.ToString();
return IPStr;
}
return IPStr;
}
Good luck

Hi,
I found this SO dependent solution. Is there a C# native solution to block all keyboard and mouse input?
[DllImport("User32.dll")]
public static extern bool BlockInput(bool enabled);
Thanks,
Dirso

Hi,
I think they all show exactly the same solution I have... did I miss anything? I'll use BlockInput, but I really would like to have a C# native solution instead (so I could also test it under Mono)
Thanks,
Dirso

My goal is to have a combo box for genders. I need the combo box to display the selected gender. Currently I have a class that has one of it's properties as gender. 1 is supposed to be male and 2 is female. However I am willing to do it however is best. I would like to incorporate binding since that is how I am doing the rest of my app. i.e. text boxes and datepickers etc

My problem is that the only thing I really know how to do in data binding is to drag an item from the data sources menu to a text box or a date time picker. Here the most important thing is the selection be the selection that has been chosen in the object. Ideally I can just use objects but if I have to I can go with xml, but either way I really need some direction.

hi
You need to work a little bit on your English,Do it in XML then, but realy i did not understand what you wanted to do.

In the most simplest form, I want a combobox that will load on a form that will have have a item selected already. In other words lets say it's a male. So in my object it will have gender equal to 1. I want my form to know that when gender = 1, then it will automatically select male. I want to use data binding because thats how I have the rest o my project set up, and I feel that I will just be asking for trouble, if I use databinding for only half. I already know I can do it with if statements.

I am making a simple reaction game. When the player clicks "Start", i want to display a label that acts as a count down.
Eg:
label.Text = "Ready";<br />
Thread.Sleep(1000);<br />
label.Text = "Steady";<br />
Thread.Sleep(1000);<br />
label.Text = "GO!";
I could do it like the above but I'd rather not use Thread.Sleep.
Does anyone know how I'd go about this?
Regards,
Gareth.

Use a timer with an interval of 1000 and increment a counter on each tick event, display the correct message depending on the counter value?

DaveyM69,
Cheers, i had thought about using a timer, but not the way you suggested.
