I have looked online for ages but can't find anything that works. Most say that you should make sure this is in both the client and server applications:
bindings
[nettcpbinding]
[binding name="NetTcpBinding_IService1"]
[security mode="None"/]
[/binding]
[/nettcpbinding]
...but I don't know where to put it in my host. I have tried and put it directly in the system.servicemodel section but I then get a CommunicationException so I don't know what to do.

Finally some help!! Yes...but I don't understand what you mean. Is it not able to log onto the host at the server?

Isn't there any way I can avoid using another thread? All I want to do is change the visibility of a control and wait for it to render before continuing, is it really that hard?!

Reading this, am I right in thinking that http is not the right 'thing' to be using because it is not hosted on a website or intranet or online? Should I be using the netTcpBinding instead so I use 'net.tcp://' instead of 'http://'? Maybe that it why it is not working, because it thinks its a service or file on a website not an endpoint?

I have not posted any code for the service, only the host console that uses it. This is the code for the client which is also a console:
static void Main(string[] args)
{
CalculatorClient client = new CalculatorClient();
Console.WriteLine(client.Endpoint.Address);
Console.WriteLine(client.State);
Console.WriteLine(client.Endpoint.Name);
Console.WriteLine(client.Endpoint.ListenUri);
Console.WriteLine(client.Login("password"));
Console.WriteLine(client.Login("hello"));
double value1 = 100.00D;
double value2 = 15.99D;
double result = client.Add(value1, value2);
Console.WriteLine("Add({0},{1}) = {2}", value1, value2, result);
value1 = 145.00D;
value2 = 76.54D;
result = client.Subtract(value1, value2);
Console.WriteLine("Subtract({0},{1}) = {2}", value1, value2, result);
value1 = 9.00D;
value2 = 81.25D;
result = client.Multiply(value1, value2);
Console.WriteLine("Multiply({0},{1}) = {2}", value1, value2, result);
value1 = 22.00D;
value2 = 7.00D;
result = client.Divide(value1, value2);
Console.WriteLine("Divide({0},{1}) = {2}", value1, value2, result);
client.Close();
Console.ReadKey();
}
Right, all I basically want is to have a computer. This computer will be downloading data from the internet and saving it (that part has nothing to do with WCF) and it will also run the server software. There will be lots of people on separate computers with a piece of software that will use the service to send a code back to the server. The server will then read that code and select the relevant piece of data (which it downloaded previously) to send back to the client (whether it be an image file or just a value). It is simple and I have it working absolutely perfectly with the client and server on the same machine, it sends the data back just like I want but the error occurs whenever I try to run the client on another machine from the server and I assumed it is a problem with how I have configured both the server and client.

That is the bit I can never do with any success! How would I change this endpoint address to make it work on another machine: http://localhost:8000/SystemControllers/Administrator
Do I just have to change 'localhost:8000' to the IP address of the machine that is running the client? I don't understand this part.
Henry Hunt

Oh, so all I have to do is change the endpoint URLs so that they are not localhosts and make sure all clients use the same URL as the host?

I've got it, it works now. I had to do DataContext = this and a few other things when updating the listview so there are now no references to the listview control itself. Thank you!

Does the XAML affect how the list reloads? Because I am still getting a NullReferenceException. I have pasted your C# code as it is without changing anything and am using this to control the items in it:
timeSteps.ItemsSource = null;
TimeStepDataCollection.Clear();
XmlDocument capabilities = new XmlDocument();
List<timestep> timesteps = new List<timestep>();
List<string> timeList = new List<string>();
List<timestep> reloading = new List<timestep>();
capabilities.Load(Data.MetOffice.DownloadXml(
"http://datapoint.metoffice.gov.uk/public/data/layer/wxobs/all/xml/capabilities?key=" +
UserProfile.Read.ApiKey(), DateTime.Now.Second.ToString()));
for (int x = 0; x < capabilities.SelectNodes("//Layer[@displayName='Rainfall']/Service/Times/Time").Count; x++)
{
timeList.Add(capabilities.SelectNodes("//Layer[@displayName='Rainfall']/Service/Times/Time")[x].InnerText);
}
foreach (string s in timeList)
{
TimeStepDataCollection.Add(new TimeStepData() {
TimeStepItem1 = (DateTime.Parse(s.Remove(10).Replace("-", "/")).ToString("dd/MM/yyyy") +
" at " + s.Remove(0, 11).Remove(5)) + ":00", TimeStepItem2 = s });
}
new Global().UpdateDataTree(set: "Observation Maps", entry: "Rainfall Rate",
step: timeList.ToArray(), type: "Observation", freq: "15 Minutes", dist:
"Met Office", serv: "OBSERVATION", unit: "mm/h (millimetres per hour)", key: "true");
timeSteps.ItemsSource = TimeStepDataCollection;
Maybe I am doing it wrong?

Ahhh I get it now... So I should just change the event args in the method to something like MouseEventArgs and add it as a handler to the ListView?
Henry Hunt
11-Nov-13 13:43pm

But that's the problem...I don't know how to use the method from that post: I mean you can't exactly go statusLabel.Content = new GlobalClasses().UpdateStatus(*** This is the bit I don't get. what do I do with this bit: DragEventArgs?***) or can you? That is what I want to know. I have never come across 'functions' with events in them apart from the obvious event handlers for controls but I wouldn't class that as a 'function' that I have written.

OK...I have found this code below:
private ListViewItem FindListViewItem(DragEventArgs e)
{
var visualHitTest = VisualTreeHelper.HitTest(dataTree, e.GetPosition(dataTree)).VisualHit;
ListViewItem listViewItem = null;
while (visualHitTest != null)
{
if (visualHitTest is ListViewItem)
{
listViewItem = visualHitTest as ListViewItem;
break;
}
else if (visualHitTest == dataTree)
{
MessageBox.Show("Found ListView instance");
return null;
}
visualHitTest = VisualTreeHelper.GetParent(visualHitTest);
}
return listViewItem;
}
...but I don't know how to use/call it because of the event in the parameters. Do I haver to attach it to an event in my ListView to use it or what? It was from here: http://stackoverflow.com/questions/12977046/finding-out-which-item-the-mouse-is-over-in-a-list-view-while-using-itemssource

But it doesn't work like that for a ListView item. Don't you have to determine the current pointer location and then get the item under it or something? That is the part I cannot do.

Thank you, I have accepted it. Just out of interest, would you say that WCF is the right way to go to match login details with a database on another computer when someone logs in or is there a better way?
Henry Hunt
18-Oct-13 12:55pm
View
ah ok...What I am trying to do is when someone signs in or fills in details to request an account it encrypts the entered data and sends it using WCF to another computer containing a database of accounts which it then decrypts the sent data and cross matches it with the database to get a correct login and then sends a message back saying it can log in. Just to make sure you know what context I want to use the encryption in. Another thing: I am amazed at how much knowledge you have about not just C# but lots of other languages and computers and encryption and a lot about everything to do with computer programming. Where and how have you got it all from?!

By huge I mean hundreds or thousands of characters and the purpose is that the number is a sequence of characters from encryption I have made where it converts inputted characters to their ascii codes and does some other stuff with it to make it 'secure'. I know it sounds like a crazy idea and that it could be cracked maybe quite easily but still...

Thank you I will have a go at that. It is annoying because I don't actually need the number to do any maths on, I only need it to stand in as a very, very long sequence of numbers.

In both errors, it is when I load the XmlDocument capabilities with either a local file or a file on the web. So it is when I request it I suppose.
Loading a file from the web: Request for the permission of type 'System.Net.WebPermission, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
Loading a local file: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Nope same error when I save it to the disk and use that instead. Is it something to do with the security rights of the application or code? But this time it is a request for a FileIOPermission not a web one I just noticed.

Hello again, I have just one more thing for you. How would I reference to a specific 'set' of elements depending on on of the containing element values instead of the attribute at the top of the 'set' of elements. For example: The code I want to read is below. How would I get the Risk level from specifying the Area element?
How would I get the risk level for the Area value of East Highland? I don't want to use indexing, ie: using SelectNodes("")[n].innerText as the 'sets' of MountainForecast elements could be in a different order Thank you.

Thank you...I now have this code but there is a problem:
int minutes = Convert.ToInt16(DateTime.Parse("2013-09-05T14:00:00").ToString("mm"));
int hours = Convert.ToInt16(DateTime.Parse("2013-09-05T14:00:00").ToString("HH"));
TimeSpan mySpan = new TimeSpan(minutes, hours, 0);
int totalSecondsSinceMidnight = Convert.ToInt32(mySpan.TotalMinutes);
MessageBox.Show(totalSecondsSinceMidnight.ToString());
It returns 14 and there surely aren't 14 minutes since midnight are there? Could you work out why this is? Thank you.

Doesn't work because the y loop follows on from the x loop. After getting the longs using x it then gets the lats with y using x to tell it to count up the same amount as it did to get the longs if that makes any sense.

Thank you so much, it worked great after a few changes. One more thing, it returns the whole element (e.g: 'time 2013-08-06T15:00:00 /time' is there a way to just get the data inside the tags or would I just use replace to replace the 2 tags either side of the data with an empty space?
