Implicit conversion warning and

[bamapookie]

I have a subroutine that I modified from code I found in this forum
(thanks). I'll include it below for public use, and to illustrate my
problem. The sub accepts a ListBox control and an enumeration. It
creates a datasource from the enum and sets the ListBox to use the
datasource. If I pass a ComboBox (which is derived from ListBox) into
the sub, I get a warning about the implicit conversion back to a
ComboBox when the Sub exits. Is there a way to avoid this warning?
Here is the Sub:

Private Shared Sub LoadEnumIntoLC( ByVal typedata As Type, _
ByRef lc As ListControl)
Dim dt As New DataTable
dt.Columns.Add( "Display", GetType(String) )
dt.Columns.Add( "Value", typedata)

For Each obj As Object In [Enum].GetValues(type data)
Dim row As DataRow = dt.NewRow
row("Display") = obj.ToString()
row("Value") = obj
dt.Rows.Add(row )
Next

lc.DataSource = dt
lc.DisplayMembe r = "Display"
lc.ValueMember = "Value"
End Sub

Note: I meant to refer to a ListControl, not a ListBox. Both ListBox
and ComboBox are derived from ListControl.

And how are you calling that routine?
