Variable Inside Variable

[Grant]

How do I, if at all possible, reference a variable with another variable
in VB.NET?

For example, if I have a form with a textbox and a button. Type var1 in
the textbox

Private Sub Button_Click(By Val sender As System.Object, ByVal e As
System.EventArg s) Handles Button.Click

dim var1 as string
var1 = "Hello World"
msgbox( /// display the contents of var1 using what was entered in
the textbox /// )

End Sub

Is this possible?

Thanks!

Do you know why variable names have been invented? Do you know what
compiling means?

Hello Grant,

I wonder, for what would you need that?
If it's about your example, then it is unnecessary as you could
reference the text box directly.

TextBox1 contains the text "Hello World"

Private Sub Button_Click(By Val sender As System.Object, ByVal e As
System.EventArg s) Handles Button.Click

MsgBox(TextBox1 .Text)

End Sub


Normally, I would not expect a user to know what variables are used in a
program. So, the input of a variable name which a user entered can match
the variable name in a program only by a very slight chance.

However, if there is only a limited number of variables used in your
program, you could list them in a ComboBox/ListBox and return the
content of that variable depending on the variable the user selected.
But consider, that variable names (e.g. var1, var2, var3) don't really
give much info about what the variable contains. Therefore, it might be
better to add the contents of the variables to the ComboBox/ListBox and
let the user choose from those.

Best regards,

Martin
