You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
In some suitable application (Excel, for example) create a simple subroutine to display a message. Your subroutine should take one argument - the message to be displayed - and produce output like this:
You can pass different messages to your subroutine to display different message boxes
If you still have time, try writing a different subroutine to unprotect or protect a given worksheet. This subroutine should take 2 arguments:
- The name of the sheet to be protected or unprotected
- Whether to protect the sheet or not (a Boolean argument)
Note that to protect or unprotect a worksheet you just apply the Protect or Unprotect methods.
Try running your macro using commands like this to test it:
Two sample commands to test your macro
If you still have time, try making the second argument optional, so that by default your subroutine will protect a sheet if the protection status is not explicitly given when the macro is run.
