First turn strict on. Learn data types. Learn about code reuse. Take this

Code

Function DeleteFile(ByVal file As String)
  If (System.IO.File.Exists(file)) Then
    System.IO.File.Delete(file)
  Else
    Return 0
    Exit Function
  End If
  Return 1
    End Function

Functions should have an As clause. Why are you returning 0 or 1? Where is the functions modifier? What about exception handling?

You are using loads of VB6 left overs also.

This method is far from being efficient.
You could just do something like that:


It's smaller, no ?
