This is probably a newbie question so bear with me as I am new to C#/OOL
I'm currently developing a client/server system where what I would like to happen is that the server reads the eventlog whenever the eventlog is updated, stores this info and then updates the console on the client with the new information. So far I've got the eventlog reading working ok but can't work out how to get the server to call a method on the client to update the client console.
I currently have a method on the client (displayInfo()) which if I run every 10 seconds does what I want but I would rather call this from the server as and when the eventlog is updated. I also currently have at least some Remoting functionality through a ClassLibrary as the client needs to read the data from the server.
Additionally - With regards to remoting is a communications channel a 2 way thing i.e once a channel is established can it be used to process data in both directions or can it only be used by a client to retrieve data from a server?
Thanks for your time

As the server will have no way of knowing what clients are available you will need some mechanism to register the clients with the server. However, depending on your usage and where the clients will reside it may be better to poll the server occasionally. Alternatively, the server could place information is a database which the clients access to display it. Again depending on several factors you may be able to use SQL Dependency to have the client refresh it's view.

That makes sense and makes it far less appealing so based on that I'll switch to periodic polling from the client as it really isn't worth the effort at this point
Thanks for your time

If clients and server are on the same network, you coluld use WCF with a Duplex Contract.
Otherwise, polling is still the best option.

You must perform the UI update from the UI thread, otherwise an exception will be thrown. This guy has a nice article about threading and winforms:

Hello,
i want to let a Silverlight-Application run in a WinForms Application (in the WebBrowser Control or the Silverlight-Control)
How can i make that they both can communicate with each other? I mean, how can my Silverlight Application invoke a method in my WinForms Application and the same in the other direction?
Many thanks

Your Winforms code would need to talk to the Javascript code that hosts the Silverlight code. This Javascript code will act as the bridge between your Winforms code and the Silverlight application.
If you are calling a Silverlight website via a web browser control, check the website documentation to see if they accept input parameters via their javascript code.Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.

If we write in the same way as above for the hashtable then we would not get the desired values.
Hashtable ss = new Hashtable();
ss["key1"] ="india";
ss["key2"] = "bharat";
foreach (object gg in ss)
{
Console.WriteLine("Key value is " + gg);
Console.Read();
}
Here we get System.Collections.DictionaryEntry and System.Collections.DictionaryEntry as output instead of the value pairs stored in the hashtable.
In this case we can help of DictinaryEntry object for iterating the hashtable.
foreach(DictionaryEntry gg in ss)
{
Console.WriteLine("Key and value are " + gg.Key + " " + gg.Value);
Console.Read();
}
A DictionaryEntry object is simply a container containing the Key and Value .

Did you post this in the wrong place? Perhaps you meant to post a tip/trick? Or maybe you meant to post this at the bottom of an article? This is a forum for C# questions.

Hi,
I have 2 dataset. I am getting values from database and binding same values to dataset1.
This method is written in refresh call so that what ever changes done or update done in the database that will be affected the values to that dataset1. but with the same time i m passing these same values from dataset1 to dataset2.
Now in that I want only those values that changed. Means i want only updated values so that my dataset2 will change accordingly. so by passing every time full dataset1 I want to pass or update only updated information.
Thanks

you can use split method then made a new id.
string _temp="1,12,123";
string[] arr=_temp.split(new char[]{','});

int id = 1;
string longID = string.Format("{0:00000}", id);
this will result in "00001";.45 ACP - because shooting twice is just silly

Hi,
When the data are integers, you store them as integers in the database, which will hold their value, and isn't interested in any formatting.
When you show such numbers, make sure to apply the format you want. One way of getting that is:
int a=123;
Console.WriteLine("a="+a.ToString("D5"));
