Thanks Christian. This what I am doing now. But it takes lot of time. And I have got lot of function to go. So I thought any way to list all the unreferenced functions. Do you know about Redgate profiler ? will that help on this issue ?

How do you close a C# application with more than one form? I can close the forms but the application keeps running in the task manager's processes. Can anyone help me out ?

You have to close the main form(where main() function resides). Once you close the main form, it will be removed from process list.

In which form your main() method resides ? How you are closing form1 when form2 is open ? Are you just hiding form1 when form2 shows ?

My main method is in program.cs and my first form is form1 and on button click event code is
private void button1_Click(object sender, EventArgs e)
{
this.Hide();
Form2 frm = new Form2() ;
frm.Show() ;
}
I want to close application on form2' button click ie button2-Click event

Write a method in your first form which closes that form. Using delegates, call this method when form2 is closed. This will close your entire APP.
Alternatively, you can pass form1 object to form2 constructor, and dispose this object when form2 closed.

hi
u can use Application.Exit() where evr u plan to terminate the application. for eg. if after showing form1 u want to close it, then on lets say btnExit_click event, u can use Application.Exit() to close the entire application and this would also remove the application thread from the task manager. This method basically terminates the application domain which the application is running in.Hope this would help.
Cheers

If your app is running with all forms closed, you must have a thread running. What if you debug, close all and hit the break menu item to see where the code is ?

Use Application.End() function it will close the application

When any user update in a server list then server send an event to client with updated list and then update the client list.
Clien hold the Remote server object and when server object raise an event then client trace that event.

thanks for your answer ,
if i have 100's of users on my server...would it be a " wise way " to costantly send an updated list to all of my 100's of users for any small event such as this ?
or is there any more efficient way to this?

So you are not able to creat a client listner event for server ?
It's easy way you can creat a client listner and handle in it with parameter.

Parwej,
As per my knowledge, we wont be able to fire events on client/server using TCP communication. Because messages will be passed through streams. So how events are fired ? Or am I missing something ?

How you are communicating with the client to server ? Are you keeping client socket object on server ? if yes you can create a method on server which returns the total count of this objects. Client has to send message to the server requesting for this number (may be you could define some proprietary protocols). Catch the message on server and call the appropriate method, and sends the message back to client.

i am communicating with client server over a tcp socket as for now i am using strings to communicate.... , i am keeping client socket object for each client on the server side , i need to send some sort of updated list or dataset to all of my clients which includes information such the username and some other stuff.... , the question is how can i send that kind of list , there must be some efficient technique for that cause almost evry server have this functionality , hope i was more clear.
thanks again!

I am not sure that you can send a dataset. But you can create a custom serializable class which holds all the information to be send, then send that object through stream.

Hy,
A nice way to send a list to the client would be to create an XML string with everything you need, something like:
<users>
<user id="...">
<name>...</name>
<surname>...</surname>
</user>
<user id="...">
<name>...</name>
<surname>...</surname>
</user>
</users>
An XML string is very easy to send over TCP/IP, it's small in size...and you can work on that string on the client side using XMLDocument or such.
Hope it helps,
Do your best to be the best

thats a realy nice idea ,
is there any classes / methods i can use in order to construct the xml strings i wish to send?
Net
|
|
|
|

actually I used my own methods to generate the XML string, mainly by manipulating a StringBuilder class

So on my desk, i have nothing but a computer running Windows XP SP2.
I want to connect a usb connector into my computer, into a component board with an LED.
Then I want to create a program in C# command line that I can turn the light on and off.
I'm told this could more difficult than I'm planning on... But if anyone has ANY ideas on where to start, or tutorials etc, I would be greatly appreciative.
Thanks

basically this kind of programs in Windows 2000/NT based systems work with a special driver u would need to download the driver first and then may be search for an API that would help you communicate with the USB device.the driver is needed because unlike the Windows9X based systems, XP,2000/NT do not allow direct access to the kernel.

If you buy a USB-to-RS232C cable, you can connect a LED (with resistor!) to one of the
serial control lines (e.g. RTS); the serial port will show up in the list of available
serial ports, and the SerialPort class will provide access to the control lines.
