VB.NET - Tip
Initializing VB.NET Arrays
In vb 6 trying to get the ubound of a array that was not yet dimensioned would result in an error. One solution around this was to write a wrapper of the ubound function, which would return -1 if the array had not been initialized. This solution is no longer necessary in VB.NET though the issue still needs to be handled, there is a much simpler solution. When you declare the array in vb.net give it a -1 as a dimension. When getuppperbound(0) is run on it, it will return a -1. This makes initial iteration and filling of arrays much easier than having to check and redim it first. Keep in mind if you try and read or write the value at -1 you will get an error.
Private Sub LoadArray() Dim theArray(-1) As int32 Dim i As Integer 'make array of values from 0 to 100 For i = 0 To 100 With theArray ReDim Preserve theArray(.GetUpperBound(0) + 1) theArray(.GetUpperBound(0)) = i End With Next End Sub
