control Array in dot net

[haitham.karim]

I am making a program to show information about the elements of the
periodic table. So I have a form with 104 buttons. How can I create
the same handler like clicking on the button then use the button index
to fetch the element information from the database without writing the
code 104 times!! I could do this easily with VB6 bot not with dot net.
Any help is appreciated.

Visual Basic no longer has VB 'Proper's Control Arrays but, to be fair,
it doesn't need them.

Sub AnyButton_Click( sender as Object, e as EventArgs ) _
Handles Button1.Click, Button2.Click, Button3.Click, ...

MsgBox( DirectCast( sender, Button ).Name & " was clicked" )

End Sub

Or, alternatively, use the AddHandler statement in code.

Of course, although we no longer have Control Arrays, we /can/ have
Arrays of Controls:

Dim oButtons as Button() = New Button() _
{ Button1, Button2, Button3 }

For Each eBtn as Button in oButtons
AddHandler eBtn.Click, AddressOf AnyButton_Click
Next
