Validating user input in c dating sites with credit scores
So before saving data, I want to validate whether all the required fields are filled (Text Boxes) by the user. I would rather use a generic function that would be passed each control on the form and based on the type of the control, separate validation logic would be written.
in case extra validation like restricting validation to some of the controls only, that would be decided at the function calling level.
For example, new fill-up data is not added to the Fillup History collection until the user taps the Save button.
Before it is saved, however, the user can review the data to make sure it is accurate.
When the user taps the Save button, a validation routine performs one last check for mistakes and alerts the user to any issues.
The following code shows a simple validation method used in the Fillup class.
Input and output handling is to ensure that data passed between computing systems do not yield unexpected behaviour on the systems, i.e. There a few methods which can make data safe for handling, with different level of security and applicability: Validating data is to ensure that data is safe prior to use.
