In this article, we will show how to insert a date into a date column using ADO.NET and VB.Net.

Here we have an Access database having 2 columns - ID [type - number] and date [type - date\time]. Now problem is date column does not accept date as string direct unless we do some changes to it. The following code shows you how you can convert a date into a proper data which database accepts just fine.
