I get this error msg "Object Referenece not set to an instance of an
object", when I try to remove an object from my listbox.

What is the correct way to remove an item

Thanks

Dim obj As New clsObject

'

obj = DirectCast(lstOwners.SelectedItem, clsObject)

Dim sqlcmd As String

sqlcmd = "delete from tbl_propertyowner where property_id = " & intProperty
& " and contact_id ='" & obj.ID & "'"

Dim ordersCMDa As SqlCommand = New SqlCommand(sqlcmd, SqlConnection)

ordersCMDa.ExecuteScalar()

lstOwners.Items.Remove(lstOwners.SelectedItem)    ' <---- Error occurs at
this line

Try changing the failed line of code as follows;

lstOwners.Items.Remove(lstOwners.SelectedItems(0))

Good luck
