You've done your math backwards. with 86.4M values generated/day and a need for only 1M values needed/day, you've got ~86 potential values for each needed one. .net timers aren't accurate to single ms values though, I saw (but don't recall where) a comparison chart of timing methods, which ranged from ~10-50ms precision.

The simple way to work this is to store the last number given and 'lie' a bit if the requests for numbers come too frequently:
x = timeInMS/100;
if( x== last )
++x;
last = x;
This gaurantees uniqueness but will occasionally give the wrong time in circumstances that cannot be avoided
Note that if the ++x is common then want you want is impossible anyway.
P.S. I haven't used hex encoding in this but why stop at base16? Use base64 and get greater precision

Yes, if the VC# compiler is to be believed. This code compiles fine on my machine
[assembly:CLSCompliant(true)]
namespace ConsoleApplication1
{
[CLSCompliantAttribute(true)]
public class Program
{
public void Method(params object[] x)
{
}
static void Main(string[] args) { }
}
}
[EDIT]
Brad Abrams[^] has this to say when discussing params,
"Do not use the VarArgs calling convention, otherwise known as the ellipsis (…), exclusively because the Common Language Specification does not support it[3]."
So yes, params is CLS compliant. Interestingly, the params keyword simply seems to make the C# compiler wrap the arguments in an object array and pass it to the callee. In fact, the params thing just seems to generate an attribute for that parameter in IL, probably for use in reflection.

Yep, that's what prompted my question. It's not directly supported in IL, and is implemented using a custom attribute on the parameter. And the calling code is always converted to using an array.

If this is a win forms application then you can drop a timer on to the form and create an event handler for its, if I remember, Tick event. In your tick event handler you can update the label.
If this is for a web application you would need some javascript to do this.

Thats a new one on me. I've never heard of that happening. Remember that the timer component is a non-visual component, so it won't show up on your form. Instead it will show up on your form designer in a separate area underneath the form - this will not affect how the form is displayed.

1. Open new C# Windows project
2. Click Windows Forms palette
3. Drag and Drop Timer on your form
4. Drag and Drop Label on your form
5. Double click in Timer and write this code:
timer1.Enabled = true;
this.label1.Text = Convert.ToString(DateTime.Now);

First add following to the declaration:
private Form2 LoginForm;
and set "IsMdiContainer" property of parent form to true
Now in page load of parent form:
this.LoginForm = new Form2();
LoginForm.MdiParent = this;
LoginForm.LayoutMdi(System.Windows.Forms.MdiLayout.Cascade);
LoginForm.Show();
Then U can add ur logic to the Login button on the Login Form:
string Username = txtUserName.Text;
string Password = txtPassword.Text;
authenticateCustomer(Username,Password);
this.Close();

What?!
The OP didn't supply nearly enough information to give an answer.
* He said login "page" - That implies that it is a web application.
* If it is a winforms application how do you know he is using (or wants) and MDI interface?
When a client gives you a vague specification like that do you go away and code for weeks to come back and have them say: No, that's not what I wanted at all.
Listen and understand - if not enough information is forthcoming then ask questions rather than blunder in. If you think you know what they mean then state the assumptions you've made: It isn't clear from what you wrote but I assume you meant X, Y and Z. If those are correct then this might be of use. If not then maybe you could fill in the details....

If that would have been ASP.NET problem, then he would have posted on ASP.NET forum. I think it is not an ASP.NET forum. That is why I had given answer in such way...........
If I had done any mistake.........
for that i feel sorry.......
Thanks,

He "should" have posted in the ASP.NET forum, yes. But the forums overlap, often people post database questions here (that should go in the ADO.NET forum - but since they are programming in C# they don't see that, they think that C# == ADO.NET not realising one is a language and the other is a framework used by many languages), or ASP.NET questions for the same reasons. Also, many people post database questions in the ASP.NET forum because their thought is that they are developing a web application (rather than a data driven application).
Where these boundaries are fuzzy it is important to ask questions to clarify what a person actually means. Each person makes different assumptions on apparently the same data.
MudkiSekhon wrote: If I had done any mistake
No mistake, just you made a set of assumptions that may or may not be correct. A former collegue of mine used to say, almost daily, "assumption is the mother of all f*** ups". So, it is important to realise when you are making an assumption so that you can either ask a question to clarify it, or explain what your assuption is. That way there is no overall misunderstanding.

Hi, I'm Mario from Italy.
Can someone explain me how I can intercept an FTP Event ?
I try to explain.
I know that some IP address send me a file by FTP. I want to know by C# code when this happens.
Anyway I need a kind of listener which tells me who send the file and where it is headed.
Can somebody helps me ?

Either you must intercept all packages and snoop on the FTP that way, or implement your own FTP server (which is quite easy at least in passive mode, and I am sure you can find base implementations out there). You could also make a proxy (write a program listening on the standard FTP port, but once connected it simply parse all data to a real FTP server running on another port - this will allow you to see all commands).

Hi,
I am newbie to c#. I want to use math function . Is there any built-in library in c# to use it. If so, which library to add in code and which reference to add in project? Thanks in advance.

Use the Math class. It's in the System namespace.

Hi
I just installed VS 2005 and I'm getting an error on an existing application. I'm exposing a component to COM using C#, when I use this COM component I get an AccessViolation. "Attempted to read or write to protected memory".
What changed with the .Net Framework 2.0 and how could I fix this.
