Can anybody explain me what's the difference between static and non-static method? Why do we want to use one over another..? For some reason, it just hit me on my back while I'm doing this game project. VS showed me an error that says:

It's from this code below:

Thanx for all

Solution is to declare weapons as static, though, I'm not asking for solution

A static method can be directly called from an object... whereas a non-static method must instantiate the object first.

Non-Static:
Dim Chet as New Person("Chet","aaa@bbb.com")
Msgbox(Chet.GetFirstName())

Static:
Msgbox(Chet.GetFirstName()) - No need to instantiate a Person Obj. but remember that your PRivate members that you rely on to "GetFirstName" must also be static... even if it is Private.

Generally if you will build a Utility class that is just all static methods you can directly call that your app or website uses a lot like IsNumeric or IsEmail, etc...

Why do want to use one over another, is there any advantages and disadvantages by using static over non-staic method? Or just if we're lazy to instantiate it...?

The very frequent example as justification for static variables is mathematical constants. No need to constantly instantiate a math class just to get Math.PI

I'm a big fan of Creating your class, having private setters/public getters and have Static Methods in the class to instantiate and return a list of itself

Like if you had a class Person


imports system.componentmodel

Public Class Person
Private _FirstName as String
Private _LastName as String

Public Property FirstName() as String
.......
.......

Public Sub New(ByRef FirstName as STring, byref LastName as STring)
me.firstname = firstname
me.lastname = lastname
end sub

Public Function GetAllPeople() as BindingList(Of Person)
Dim People as new BindingList(Of Person)
' Hit DB and get Datatable of all people
For each PDR as PeopleDataRow in PeopleDataTable
people.Add(PDR)
Next
return people
end function

end class

This way it's always a 1liner for you objects directly to a control... then just define what matches what

PeopleDropdownList.DataSource = Person.GetAllPeople()
PeopleDropdownList.DisplayMember = "FirstName"
PeopleDropdownList....... = whatever....
