You've just answered your own question. When a user connects, get all of the connected users from the array. When a user disconnects, or you find a client is no longer accessible tell all connected clients to remove that user.

This is exactly the problem,

My Enum is residing in main application as it is the main user of the Enum. I added class library to solution and would like this Enum to be shared from class library without re-defining it. Also don't want to move Enum declaration to class library since the code that mainly using this Enum residing in main application.
Any ideas?

Well you should put your enum in the library regardless of what else is going to use it.
But if you insist on having it in your form just make it public and add a reference to the .exe from
the library
If at first you don't succeed ... post it on The Code Project and Pray.

It is in fact public in my main executable. But if I add reference to the exe from class library I will have circular reference error during add.
I am thinking to create a second assembly, collect all shared classes and enums, then add reference to this library from both executable and other class library. Hope it's better idea.

This is absolutely better idea also it is also the best solution that comes to my mind. For your requirement the only solution is creating a base assebmly can be named as InfrastructureLayer that referenced by all other assemblies.

Or would that be a third assembly? Yes, that sounds like a good idea.
|
|
|
|
|
yea, sorry. third assembly (second class library).
I already went that way and looks very nice so far.
|
|
|
|
|
Yes, your idea is 100% better ...i don't know what i was thinking telling you to add a circular reference.
I guess that just goes to show you, even if someone answers your question you still need to think about it.
If at first you don't succeed ... post it on The Code Project and Pray.

Hi
I have xml file format mentioned "code" section.
In my program, i know Failure_ID(it comes from some other binary file), based on "Failure_ID" i want to read "Name" value from XML.
i want to read "Name" thru "Failure_ID".
Please help me to write code for this.
I am using C# windows Applcation, .net 3.5 framework
Thanks
<Failure_Table>
<Failure_ID="1" Name = "Failure_1" Description = "TBD" />
<Failure_ID="2" Name = "Failure_2" Description = "TBD" />
<Failure_ID="3" Name = "Failure_3" Description = "TBD" />
</Failure_Table>

What have you tried ? What research have you done ? What books do you own ? The key words for your google search are XPath and XMLDocument.

I would have suggested that you use SelectSingleNode (member of XmlDocument), but that won't work since this is not valid XML. The problem is this part <Failure_ID="1", which as far as I can see quickly is never valid XML, and certainly not in this case. The problem is, there is either no element name or no attribute name (but it's impossible to tell which is missing). I suggest you change it to <Failure ID="3" Name="whatever" Description="Something">
Or if you're not in a position to change the format, use an other way to read the data - not as XML because that's not what it is.
If you go for the first option, the code to select the Name based on the ID could be something like
myDocument.SelectSingleNode("/Failure_Table/Failure[@ID=\"" + theID + "\"]/Name).Value
(warning: untested, and does not do any checking so will fail if Name is not present)
Hope that helps

Hi the child xml nodes are invalid. you need to add element name to the child element nodes.
Below format is be the correct one :
<Failure_Table>
<Failure Failure_ID="1" Name="Failure_1" Description="TBD" />
<Failure Failure_ID="2" Name="Failure_2" Description="TBD" />
<Failure Failure_ID="3" Name="Failure_3" Description="TBD" />
</Failure_Table>
And here is the C# code :
string _xmlData = "<Failure_Table>" +
"<Failure Failure_ID=\"1\" Name = \"Failure_1\" Description = \"TBD\" />" +
"<Failure Failure_ID=\"2\" Name = \"Failure_2\" Description = \"TBD\" />" +
"<Failure Failure_ID=\"3\" Name = \"Failure_3\" Description = \"TBD\" />" +
"</Failure_Table>";
int desiredFailure_ID = 2;
string name;
XmlDocument doc = new XmlDocument();
doc.LoadXml(_xmlData);
XmlNodeList list = doc.SelectNodes(@"//Failure");
foreach (XmlNode pNode in list)
{
int failure_ID =int.Parse(pNode.Attributes["Failure_ID"].Value);
if (failure_ID == desiredFailure_ID)
name = pNode.Attributes["Name"].Value;
}

Good afternoon.
I have a form (ucTabs) with two labels (tslProgress: "Progress" tslStatus: "Status") and a progressbar (tsProgBar).
When a series of methods in the DAL layer are executed, I want to increment the progress bar and change the tslStatus to "Processing xxxx method " + "25%", "Processing yyyy method " + "50%", "Processing zzzz method " + "75%", etc.
Any suggestions?
Thank you, WHEELS

I have my DAL raise events for logging progress, but a consumer could attach a handler that updates a ProgressBar if it wanted.

Good afternoon.
I have the following code in my DAL.cs:
private ucTabs ucT = new ucTabs();
private Timer time = new Timer();
private void InitializeMyTimer()
{
time.Interval = 250;
time.Tick += new EventHandler(IncreaseProgressBar);
time.Start();
}
private void IncreaseProgressBar(object sender, EventArgs e)
{
ucT.tsProgBar.Increment(25);
ucT.tslStatus.Text = ucT.tsProgBar.Value.ToString() + "% Completed";
if (ucT.tsProgBar.Value == ucT.tsProgBar.Maximum)
time.Stop();
}
public void importStuff()
{
InitializeMyTimer();
}
Can't seem to get the Progress bar to move at all. Any suggestions? WHEELS

I have one doubt regarding this? Why are you doing all those stuff in Data Adapter Layer ? You should display the progress only On UI layer itself. User background wroker thread to call the DAL method. which will show the progress of execution. If you are doing all these stuff in DAL, where are you retruning the value to UI?

Good morning Abhijit.
I am calling an import method (which call several other import methods) from the form class.
I am also referncing the form's progres bar and label in the DAL.
I had some difficultly getting the background worker thread to work.
You would think there was a simple way to accomplist what I am trying to do.

Instead I would do something like:
dal.OnProgress += IncreaseProgressBar ;
Bear in mind that when using a thread to do the work, IncreaseProgressBar will need to check InvokeRequired and call Invoke if needed.
This way, when the dal has an update, it will execute IncreaseProgressBar itself without having to know what it does or why.
If you haven't learned events[^] yet, this would be a good time.

I have created a class object to diplay information.
It is a Panel with a Button on it.
When the Button is pressed it process some data and displays the data on the Panel on Labels, etc.
The end result (After clicking a Button on my DisplayClass)is a value that I want passed back to the Form that has my DisplayClass on.
I had though that I could pass a pointer to a function to my Display class and have it call it that would drive code on my main form, but I can't figure it out. 
TestDisplay = new UsageDisplayPanelClass();
TestDisplay.Location = new System....
TestDisplay.Size = new Syste....
TestDisplay.Click += new System.EventHandler(TestDisplayClick);
The Click event never gets back to my main program because it is captured through a Button.Click in my TestDisplay Class
Is there a way to have both my Class handle the button click then have the event resent to my main program?
Thank you in Advance
Douglas
