VBScript Constants A number of useful constants you can use in your code are built into VBScript. Constants provide a convenient way to use specific values without actually having to remember the value itself. Using constants also makes your code more maintainable should the value of any constant ever change. Because these constants are already defined in VBScript, you don't need to explicitly declare them in your code. Simply use them in place of the values they represent. Dani Vainstein

Constants MsgBox Constants Color Constants Date and Time Constants Defines constants used in the MsgBox function to describe button visibility, labeling, behavior, and return values Color Constants Defines eight basic colors that can be used in scripting RGB, CMYK.

Lab 6.1 Use the InputBox for retrieve a password, title login to EX 6.1. If the input is an empty string, exit the program. Declare a constant MY_PASSWORD. Declare a constant MAX_RETRY = 3. If the password is correct display a MsgBox with a wellcome message + information icon + EX 6.1 title. Display a message each time password incorrect + question icon and a question to retry or cancel the login process. If the password is typed wrong more then MAX_RETRY times, display an error message with an error icon, then exit the program. Use the Do..Loop (While or Until). Tip Use the Exit Loop statement. Check the value returned from MsgBox. Dani Vainstein
