My challenge right now is to encrypt the data stored in a database with a VB.Net application I am developing. I have a function to encrypt the data, but I can not figure out how to send it values in the dataset. I have no problems binding controls to my dataset, but when the application opens I want to send each value in the dataset to the function that decrypts the value so the data can been interacted with by the user. Then I want to send each value to a function to encrypt it when the app closes. This way the data stored in the database will always be encrypted. I can not find a way to edit values in the dataset unless it is through a bound control. Is there a way to populate an array with the dataset, change the values in the array, and repopulate the dataset? Or any better ideas? I am new to ADO.Net. Thanks in advance- Harvey
