Class 3 - Overview Static Variables Message box Input Box

Static Variables A Static variable retains its value between calls to the procedure as long as the form is open. Syntax: Static varname [As Type] Very useful for maintaining counters within a local procedure. Example: Static intCount As Integer

Message Box A Message box is a handy tool to communicate with the user Gives information to the user Accepts user input There are many pre-set constants that makes the Message box very versatile Many times there is no need to create a custom Message box

Message Box Syntax: MsgBox(prompt[, buttons] [, title] [, helpfile, context]) Prompt = The message text Buttons = Optional – [OK] is default Title = Optional – The text in the blue bar Starting and closing parentheses ( ) are required only if you are receiving user input Return value is an integer between 1 and 7

Input Box Are useful if you want to receive input from a user Not as flexible as Message boxes Has a very “plain” look Accepts user input with either [OK] or [Cancel] buttons Not possible to distinguish between an “empty” user input or selecting [Cancel] It is possible to “control” it with code – Future Class!!!

Input Box Syntax: InputBox(prompt[, title] [, default] [, xpos] [, ypos] [, helpfile, context]) Prompt = Message to the user Title = Optional - The text in the blue bar Default = Optional - Default value provided to the user NOTE: Returns a String value of user input

Review of Class 3 Static variables are good for keeping count in a local procedure Message boxes are very versatile Use them often Input boxes are useful for user input Not the greatest, but it works
