Hi guys ,

I would like to ask whether is there a better way to return an object.

For example.



Object Class with properties

Public class objProps

    Property ORDERNUM() As String
    Property OWNER() As String
    Property INFO1() As String
    Property INFO2() As String

End Class 

Runtime class where all the methods will be in here

Public class runTimeClass
       inherits objProps




Public function FillData() As runTimeClass

  Dim x as new RunTimeClass()

'' filling the object 
   x.ORDERNUM = "111"
   x.OWNER = "TEST"
   x.INFO1= "123"
   x.INFO2 = "pop"

  return x

End function

End class

'' This is a console program..

Public Class MainClass



Sub Main () 


 Dim x as new RunTimeClass()

  x = x.FillData()


  console.writeline( x.ORDERNUM )

End sub 

End Class

In this main class , the portion where

 x = x.FillData()

Are there any other efficient ways ? Greatly appreciated if anyone could provide some suggestions or samples =)

Have you even tried to run this code? Because I suspect it should fail due to inconsistent case usage in your names.

01 Public class runTimeClass
08 Dim x as new RunTimeClass()

Otherwise, I'm missing the point to this post. Is there a problem/error?

tlhIn`toq: VB.net is case-insensitive.

shadachi: What do you mean by "Are there any other efficient ways ?"
Efficient how?

Wow, really? Learn something new every day. That must make it harder on people making the transition into other languages; having to go from being sloppy to paying attention.

[shadachi]

Sorry for the late reply..

Sorry for the sloppy case problem. but yes it is a workable code . Just that this is not a full set of codes =D

@Adam , Yes . Is it a common practice where we use like the following to reference the object in order for the object to fill its properties? If So , wouldn't it be messy ?

 	 Dim x as new RunTimeClass()
	 
	  x = x.FillData()

2nd question , Is it possible to do like the following without the referencing like x = x.FillData() , what impact will it make ?

 Dim x as new RunTimeClass()

  x.FillData()

I'm thinking in your filldata method you could just use a sub and then use mybase.{Property} = ???

Then in your sub Main you would use

Dim x as new RunTimeClass

x.FillData

[AdamSpeight2008]

Is there any reason preventing from using constructors?

@CharlieMay , thx . would give that a try . Mybase.{property}

@Adam , Well... This is just one of the methods in the RunTime class , there are many other more methods within.. that's why i don't use the constructors for this function. xD


UPDATE *

I did it .. XD thx Charlie and Adam for the help..

What i did was changed it to sub first instead of a function . Used Me.{Property}

Public Sub FillData() As runTimeClass
	 
	 
	 
	'' filling the object
	   me.ORDERNUM = "111"
	   me.OWNER = "TEST"
	   me.INFO1= "123"
	   me.INFO2 = "pop"
	 	 
	End Sub

I think if you read the Inheritance Tutorial, you'll get what I mean.

I just read it myself. Good work!

Awesome Tutorial Adam..It actually allowed me to look at inheritance from a different perspective ..

oh yea..just to let u know if not mistaken

X:= 4 Y:= 5 Z:=0

shouldn't it be in the output section

X:= 4 Y:= 5 Z:=6

and oh yea.. this part i don't really understand. The colon operator u've used.

 _Angle = Angle : _Distance = Distance

The colon operator is used to combine multiple statements together. It can lead to dense and cluttered lines but when used in moderation (like Adam's example) and to join relatively related statements it is fine. There is nothing wrong with them when used appropriately

Well spotted
Read the reply to the tutorial.
