I have a textbox for searching a database. When the text changes it runs a functioncFilter() and loads the records. It is set up to search different columns of a database, and it unfortunately only the first record matching is pulled from the database. Example: when the database contains two people (Bob Smith & Bob Smitt) the user can type the name in the search field. However When the user types Bob Smit it only returns Bob Smith and not both names in the database. I want this to act as a filter, dynamically changing the last with each additional letter typed in the search box. Below is my source code,
Public Sub cFilter()
Dim myConnectionstring As String = ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & My.Settings.dbLocation & ";Persist Security Info=True;Jet OLEDB:Database Password=BCFAdmin")

View 2 RepliesI am trying to do a SQL query to see if an Address already exists in my database. My addresses are structure like this:
line1
line2
line3
city
state
zipcode
country
Sometimes line2 and line3 are NULL values in my database.I am using .NET TableAdapter and DataTable to make my query. When I try to pass in my line2 parameter (@line2) it is equal to a string with value = nothing. My database does not interpret this as NULL and says the records don't match, but I know they do? How do I pass in a string = nothing and have it compare to a NULL value in the database as being equal? I have tried string = DBNULL.value but won't compile.I have done similar comparisons with integers etc. using integer = Nullable (of integer) but this does not exist for strings.
