I'm having an issue with passing values from text boxes through to
the fill subroutines on my dataTableAdaptors.
Basically this is a simple example that illustrates my issue
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
MsgBox((Nothing = "").ToString) 'Returns "True"
MsgBox(dostuff(Nothing)) 'Returns "not a date"
MsgBox(dostuff("")) 'Throws Exception - Conversion from string
"" to type 'Date' is not valid.
End Sub
Function dostuff(ByVal aDate As System.Nullable(Of Date)) As String
If aDate.HasValue Then
Return CType(aDate, Date).ToShortDateString
Else
Return "not a date"
End If
End Function
I'm unsure what to do here, I tried to create a function to converts
empty strings to Nothing and execute that before passing the values of
the text boxes to the fill functions but that produces the same error.
Thanks in advance,
Joel
