Of course it doesn't you've not told it to! All you've done is take the current date/time and converted it to text to display in a label. If you want it to update, you need to tell it to - computers are not mind-readers!
Set up a timer, make it poll every second, and in the Tick event update your label to the current date/time just as you did in your original code.

yes you right..
i take timer and set it interval = 1oo
now how i implement this ??

There are so many examples of doing this on the internet, that it is obvious that you did not even attempt to do any research for yourself.
Now stop trying to get other people to write your code for youyou'll never learn anything that way. Fire up google and do some research for yourself.
Post back here with some example code, if it goes wrong.
Actually, you don't need to google, all the information you need has been given to you in the answers in this thread. Now have a go for yourself.

Hi All
Here is a cut down version of the code that I am working on and having problems with
The first Code Block works fine
public class MyBase<T>
{
public string MyName;
public object MyValue;
public T ValueTyped
{
get {return (T)MyValue; }
set { MyValue = (object)value; }
}
public MyBase(string NewName, T DefaultValue)
{
MyName = NewName;
ValueTyped = DefaultValue;
}
}
public class MyString : MyBase<string>
{
public int MyMaxLength = 50;
public MyString(string NewName, string DefaultValue, int MaxLength)
: base(NewName, DefaultValue)
{
MyMaxLength = MaxLength;
}
}
public class MyInt : MyBase<int>
{
public int MyMaxValue = 100;
public MyInt(string NewName, int DefaultValue, int MaxValue)
: base(NewName, DefaultValue)
{
MyMaxValue = MaxValue;
}
}
public class Testing
{
public void test()
{
MyString _string = new MyString("Name","",20);
MyInt _int = new MyInt("Size",10,72);
}
}
Up to here all is OK. The next Code block falls over. I am try to create an array that can contain MyString and MyInt classes using the base class MyBase so that it can be used like in class testing2.test
public class MyBaseArray
{
List<MyBase> ListAll = new List<MyBase>;
public void AddMyBase(MyBase Item)
{
ListAll.Add(Item);
}
public MyBase Find(string name)
{
foreach (MyBase _MyBase in ListAll)
{
if (_MyBase.MyName == name)
{
return _MyBase;
}
}
throw new Exception("Item Not in list");
}
}
public class testing2
{
public void test()
{
MyBaseArray MyBases = new MyBaseArray();
MyBases.AddMyBase((MyBase)new MyString("Name1","Fred",20));
MyBases.AddMyBase((MyBase)new MyInt("Size1",10,72));
MyBases.AddMyBase((MyBase)new MyString("Name2","George",20));
MyBases.AddMyBase((MyBase)new MyInt("Size2",8,72));
MessageBox.show(MyBases.Find("Name2").ValueTyped);
int FontSize = MyBases.Find("Size2").ValueTyped
}
}
The Idea works If I remove the Generics from MyBase and make ValueTyped return an Object.
The question, is it posible to have a array of MyBase where I can use .ValueTyped to return a string for MyString and an int for MyInt.
without have to do any type casing?
MessageBox.show(((MyString)MyBases.Find("Name2")).ValueTyped)
int FontSize = ((MyInt)MyBases.Find("Size2")).ValueTyped
or
MessageBox.show((string)MyBases.Find("Name2").ValueTyped)
int FontSize = (int)MyBases.Find("Size2")).ValueTyped
The original code above is far more readable.
Generics did seem like the way to go until I hit this problem.
Thanks any help.

I suspect the problem is because your list is of MyBase but MyBase<int> and MyBase<string> are actually different types. I'll try and have a think of a solution.

Hi DoctorMick
The List<MyBase>is tring to get me to do the following List<MyBase<string>> or List<MyBase<int>> however I would like both to be in the List
Thanks James

how do i use sendkeys.send in my application
how do i verify that i pressed the key
this is the code

Hi,,
I need to place the cursor at the end of the text in combo box.
This should b done when the combo box get the focus.
How can this be achieved in c#.
Can any one help...
Thanks....

pp.p wrote: Can any one help
I will help, but not give you the code.
0. Check the event that fires when the focus enters the combo box.
1. You need to know the length of the text.
2. Change the selection start position and length.
Now, that should be enough to get you on your way. Come back soon, ya'here!

My work here is done.

Hello all,
As most of you will already know, when one imports a WSDL into a project the resulting web reference allows the developer to call the WSDL methods, for example:
int resultCode = DoSomething(valueA, valueB, ref valueC, out valueD);
However, this import wraps the entire message creation / send / result parsing into code that is embedded with .NET libraries.
I need to "intercept" the raw outgoing SOAP message and send it somewhere else via remoting. The server at the end of the remoting call will then perform the HTTP send and synchronously return the raw SOAP response. I then need to parse the SOAP response so that it can be parsed into the return/ref/out objects the method (as above) returns.
Does anybody know of a way to do this?
My original stab was to create a code generator app (as an alternative to adding a web reference) that would read the WSDL and generate a callable stub. However I am having trouble generating the SOAP messages and parsing the incoming sync response. So another question would be:
Does anybody know of a way to create/deconstruct SOAP messages?
|

I have a pretty strong feeling that you may need to implement SOAP extensions.
Using SOAP extensions you can intercept the outgoing / incoming SOAP messages at different stages in the processing pipeline in order to perform additional functionality with them.

If I know some X,Y co-ordinates of screen (IE window), when a web page is opened in IE, can we get what HTML Element is there at that specific rect position?
I mean, For example, open http://www.google.co.in/ in IE, that page consists the text like "Web", " Images" etc.,
If I know the rect(X,Y) co-ordinates of "Web", then can we get html tag in which the text belongs(as it is present in <B> tag)?
Similarly If I know the rect(X,Y) co-ordinates of " Images", then can we get html tag in which the text belongs(as it is present in <A> tag)?
How can I do this in c#?

Hello everybody,
i've got this problem:
I create a new Windows Form (BuyWindow.cs) out of the static class Program.cs which shows me a financial chart. I am using a API from a Data Provider (Taipan Realtime) to create Streams which deliver the actual price information for my security. This Streams I also create in the Program.cs:
private static BuyWindow f;
internal static void testwindow()
{
if (Tapp == null) { Tapp = new TaiPanRTLib.TaiPanRealtime(); }
f.build_chart();
f.Show();
DataStream TPStream;
TPStream = (DataStream)Program.Tapp.DataStream;
TPStream.Add(17956195, 1);
TPStream.Brief += new _IDataStreamEvents_BriefEventHandler(TPStream_BriefBuyWindow);
TPStream.Geld += new _IDataStreamEvents_GeldEventHandler(TPStream_GeldBuyWindow);
}
static void TPStream_GeldBuyWindow(int SymbolNr, float Kurs, float Volume, DateTime Zeit)
{
f.update_bid(Zeit, Kurs, false);
}
static void TPStream_BriefBuyWindow(int SymbolNr, float GeldKurs, float Volume, DateTime Zeit_kurs)
{
f.update_ask(Zeit_kurs, GeldKurs, false);
}
As you can see, I create the Events TPStream_GeldBuyWindow, TPStream_BriefBuyWindow which are triggered every time a new price exists on the Stock Exchange.
In the BuyWindow.cs there is the Code which updates the Form with the respective price(s):
public void update_bid(DateTime bid_time, float price, bool build)
{
if (this.InvokeRequired)
{
this.Invoke(delegateUpdateBid, new object[] { bid_time, price, build });
}
else
{
bidseries1.Points.AddXY(bid_time, price);
if (!build)
{
current_bid = price;
update_label(price.ToString(), "label9");
}
}
}
}
And here's the Problem: The Price is updated just one SINGLE time. That means, the first price after creating the chart and showing the BuyWindow is delivered and shown on the BuyWindow form. But then, the Stream Events in the Program.cs class are never updated again although there are new prices available.
I found out, if I outcomment the f.updatexxx line(s), the Streams work as intended. Every time a new price is settled on the Exchange, the Events are triggered.
So it seems that the Invoke method somehow causes the Program.cs to loose connections with the Stream Events or whatever.
I hope I described the problem good enough  Any hints would be appreciated!

Hi,
your code looks fine to me; you do need a similar InvokeRequired pattern for BuyWindow.update_ask() which you did not show.
I would add some logging to the handlers (maybe a Console.WriteLine would do).
BTW: by convention public identifiers use PascalCase, i.e. they start with a capital (update_ask)

Thank you for the Hint The method update_ask is exactly as implemented as the update_bid method, I just did not show it because of easier reading purpose.
I just moved all the DataStream - respective Code to the BuyWindow.cs, but the Problem still exists.

|

Solved!!
I just made DataStream TPStream a Class Variable instead of defining it within a method and now it works!

|

|

Right. I missed that one; your object got collected, giving it some delegates does not keep it alive!
