Problem: public array loses elements (in usercontrol)

[VB Programmer]

I have a public array (in a usercontrol) defined as:

Public arrWebServers(0) As WebServers

' FYI:
Public Structure WebServers
Friend ServerName As String
Friend MapIdAc As Short
Friend MapIdDc As Short
Friend DatabaseName As String
End Structure

In a sub called ArrayLoad I load the array with several elements (let's say
10). (FYI: Each time I add an element I do a ReDim Preserve on it and
increase it by 1.) I checked the array as it was loading and it indeed
loaded.

Later, when I call arrWebServers.GetUpperBound(0) (from another sub WITHIN
the usercontrol) it has NO ELEMENTS.

Ideas?
