Troubleshooter of Error: Display the box to confirm and deliver message before running the code

Display the box to confirm and deliver message before running the code

Hi,
When the code are added to ribbon, there may be the instance that we click on the code by mistake.
Because we can't undo, we may lose the original data.
In addition, there are certain criteria to apply for each code (For example, where is data range located
or where is the result located).
To avoid that, I want to set an alert before the code run by adding some more lines in the code, which :
- Display the message box .
For example : "Row 1 is header.
Data in column A,B,C.
Result in column E,F,G"
- Display the confirm box to run the code : "Do you want to run the code?"
What is the line of code I need to insert ?
Thks
