For example, i need to perform a validation search to prevent the user from keying two same primary keys. I have no intention of using the try...catch because its error message is quite profound to the novice user. To make it simple, i will go for another method. That is the question i am asking.
One more question, I have used select...where SQL statement to find the proper record but how to pass the data and display them in each textbox. Thank you.
