Answer 1

Put the values into an array and use the Max function on IEnumerable:

'Requires Linq for Max() function extension
Imports System.Linq
'This is needed for List
Imports System.Collections.Generic

' Create a list of Long values. 
Dim longs As New List(Of Long)(New Long() _
                                   {4294967296L, 466855135L, 81125L})

' Get the maximum value in the list. 
Dim max As Long = longs.Max()

' Display the result.
MsgBox("The largest number is " & max)

' This code produces the following output: 
' 
' The largest number is 4294967296

As David suggested, keep your values in a list. That's easier than using individual variables and can be extended to as many values as requested (up to millions of values).

If you need to keep individual variables for some reason, do this:

Dim max As Integer = a
Dim name As String = "A"
If b > max Then
    max = b
    name = "B"
End If
If c > max Then
    max = c
    name = "C"
End If
If d > max Then
    max = d
    name = "D"
End If
' ...  extend to as many variables as you need.
MsgBox(name & " is greater")
