Custom Backgroundworker with VB

Hi All,

Here is a sample code of how to create a class that implement a custom backgroundworker with VB.NET 2005/2008;
Prerequisite: you have to be familiar with Delegates and Events.

1-Create a new project.
2-Right click on the project name and choose Add New Class
3-Name the class tBackgroundWorker.
4-Imports System.ComponentModel
5-Serialize this ToolboxBitmap with follow by the class tBackgroundWorker.Usen _ if necessary.

Essential Class coding(C#)

Let`s declare a class named Cars.Remember each class contain fields,methods,sub-classes and more.
standard definition:access return type class
Access modifier is how the class will be accessed could be publicly,privately,protected....
public class Cars
{
//let`s declare some fields ,you can add more depending on your requirement.
public int ntires;
public bool sunroof=true;

//let declare a method

public void Start()
{
Console.WriteLine("Vooommm......");
}

Public void Stop()
{
Console.WriteLine("Stoppinnnnnnng.....");
}

//You could add Property,structs and more

} //end class Cars


//Now let create a class that will use all fields and methods of Cars class=INHERITANCE
//u use : in front of sub class like JapaneseCar

Public class JapaneseCar:Cars
{
//JapaneseCar class will inherit all fields,methods.... of Cars Class and can implement it own
//methods,fields....


}

//Let say i dont a sub class inherits a given class .The anwer is you need to seal the class you dont to be inherited with the keyword sealed
//Let create 2 classes:

public sealed class AllCars
{
//field,properties,methods...
}
public class ChineseCars :AllCars
{
/Putting a colon in front of ChineseCars will not work and generated error because
//AllCas class is sealed
}

Introduction to ClickOnce API

Prerequisites: Visual Studio 2005/2008;VB.NET ;C#
1-Imports System.Deployment.Application
2-Got to Properties of your application/Publish tab/Unchek Application should check for Update
3-Make sur you set Update location (very important)

VB.NET

Return
Catch ioe As InvalidOperationException
MessageBox.Show("This application cannot be updated. It is likely not a ClickOnce application. Error: " + ioe.Message)
Return
End Try
If (info.UpdateAvailable) Then
