If all of the fields contain valid information, the program displays a message dialog stating this and the program exits when the user dismisses the dialog.Hello: Using Win Forms, certain users may change the value in a combobox, others may not. I need to check the user's rights before committing his or her changes in the box and restore the previous value if he or she is not allowed (or not let the value be changed in the first place). Ken Using Win Forms, certain users may change the value in a combobox,others may not. I need to check the user's rights before committing his or herchanges in the box and restore the previous value if he or she is notallowed (or not let the value be changed in the first place). Now the only thing I need to be able to do is reset the original value and allow the user to continue. If there is a match, then the event handler proceeds to validate the first name.This process continues until the event handler validates the user input in all the Text Boxes or until a validation fails.
If the value of Success is false (i.e., there was no match), then it displays an error message and sets the focus back to the first Name Text Box so that the user can retype the input and terminate the event handler.
Actually validating algorithms is a very interesting topic and it's really not that hard.
In this post I'll show how to validate your algorithms (I'll take the Face Recognizer in this example).
This article explains how to use Regex in a Windows application.
The code example uses Regular Expressions in C# to validate name, address, and telephone number input by a user.

There are several strategies for validating, but I think you should start with a simple Cross Validation and go on from there, for informations on Cross Validation see: One of the public available datasets, that is already coming in such a folder structure is the AT&T Facedatabase, available at: * unpacked it is going to look like this (on my filesystem it is unpacked to I suggest using a Stratified Cross Validation.
