How to reload data from data base to Webpage After some seconds ?. - C# Discussion Boards

Not really a C# question but I'll help anyway.

You need to add a META tag inside that page's HEAD section. For example:

This little snippet will reload CodeProject.com every 15 seconds.

But in WebPage have using <marquee> tag to scroll page.
I want reload data in page at time, then position of all records in page not change <-- because page load then setting all position of records.

Example:

time A:
Position records.
Record 1
Record 2
Record 3
....

time B: <--- at time update data.
Record 2
Record 3
....

if using javaScript -- meta --> Position Record of B is.
time B:
Position records.
Record 1
Record 2
Record 3
....

You can use javascript timer and submit the page after 15 second and on page load you can update the data. not need to use ajax.

Why Round like this?

From the docs the definition of Math.Round

The integer nearest a. If a is halfway between two integers, one of which is even and the other odd, then the even number is returned.

So 4.5 rounds to 4 and 3.5 rounds to 4. Why?

Because it uses the Banker's Rounding algorithm to do the rounding. It's overrideable so you can use your own round method(s).

I learned banker's rounding in High school, so it just seems natural to me. Check out this[^].

Take care,

Problem on web services

Hello:

I have here a problem where I am using web services.

From this example you can see that webservices is very tolerant of extra fields or missing fields. One issue though is that if you run one of the webservices and then update the other project's web reference it generates partial class code for your remote object in the namespace of the webservice. This is a problem.

For instance:

If you run the solution Version1 and then open the solution

Version2 and update the Web Reference in the project (you have to show hidden files) you get a file called Reference.cs.

In Reference.cs the system generates a wrapper for the class Foo

/// <remarks>
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml","2.0.50727.1378")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://tempuri.org/")]

public partial class Foo {...}

The problem is that when it does this it will return this object as when you call HelloWorld.

static void Main(string[] args)
{
ConsoleApplication1.localhost.Service1 s1 = new Service1();
MyLibrary.Foo f1 = new MyLibrary.Foo();
f1.Prop1 = "New";
MyLibrary.Foo f2 = (MyLibrary.Foo)s1.HelloWorld( f1);
System.Console.WriteLine("F1.Prop1=" + f2.Prop1);
}

Which is not what you want. The intended object is MyLibrary.Foo not ConsoleApplication1.localhost.Foo. Please figure out how prevent VS from creating the wrapper or any other solution.

Below are the project codes:
"Version1" Solution:
Webservices:
using System;
using System.Data;
using System.Web;
using System.Collections;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.ComponentModel;
using System.Xml;
using System.Xml.Serialization;

using MyLibrary.Lib;

namespace Version1
{
///

/// Summary description for Service1
///

[WebService(Namespace = "http://localhost/")]
[ToolboxItem(false)]
public class Service1 : System.Web.Services.WebService
{
[WebMethod(EnableSession = true)]
[XmlInclude(typeof(Foo))]
public MyLibrary.Lib.FooHelloWorld(MyLibrary.Lib.Foo foo1)
{
foo1 = "Updated";
return foo1;
}
}
}

"MyLibrary.cs"

using System;
using System.Data;
using System.Configuration;
using System.Xml;
using System.Xml.Serialization;

namespace MyLibrary
{
public class Foo
{
private string m_prop1 = null;
public string Prop1
{
get { return m_prop1; }
set { m_prop1 = value; }
}

private string m_prop2 = null;
public string Prop2
{
get { return m_prop2; }
set { m_prop2 = value; }
}

public Foo()
{
m_prop1 = "abc";
m_prop2 = "cde";
}
}
}

Console application: "Program.cs"
using System;
using System.Collections.Generic;
using System.Text;
using System.Xml;
using System.Xml.Serialization;

using MyLibrary.Lib;
namespace ConsoleApplication1
{
static void Main(string[] args)
{
ConsoleApplication1.localhost.Service1 s1 = new Service1();
MyLibrary.Foo f1 = new MyLibrary.Foo();
f1.Prop1 = "New";
MyLibrary.Foo f2 = (MyLibrary.Foo)s1.HelloWorld( f1);
System.Console.WriteLine("F1.Prop1=" + f2.Prop1);
}
}

*** NOte *** localhost is the name of the web services when i add reference.
If you can provide solution in this Version1 solution it will work also on Version2 solution.

Hope anyone can save me from hell... Thanks

How to make a random number generate? And also, every time it is called, will it generate a new random number? (between 1 and 20, please). Thanks in advance.

You seriously need to start learning how to use MSDN.

It will do what you tell it to.

When I use a Random I prefer to make one static instance that I use throughout the program.

private static readonly System.Random randy = new System.Random() ;

To get a random number in the range 1 -- 20:

int x = randy.Next ( 20 ) + 1 ;

Every day, you post questions that show you have no resources on C#, and are scared to use google. We love to help, but you're never going to learn to code unless you learn how to do basic research, and invest in at least one good book.

Trust me, I do invest in books, but it's not the same as a person telling you directly and so on, not that the site is the same either... The books are things that can't explain it to you if you don't understand what it says, though they usually do help.

Then use that book, to whack yourself on the head if for nothing else.

If you want to learn from a live person take a class.
