2. Class 3 - Overview
Static Variables
Message box
Input Box

3. 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

4. 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

5. 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

6. 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!!!

7. 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

8. 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
