Below examples show how to use MsgBox to test dynamic variable values as they change while the code is executed. Display a message box to get the value of a variable - MsgBox VariableName - after the code line which you want to validate, and then remove this after finishing writing the macro. Use a message box immediately after the code line wherein the variable assumes a value, to check how the procedure runs with the dynamically changing variable values. Using a Message Box to check the changing values of a variable, is one of the most basic and often used methods while writing macro code. VBA provides numerous Debugging tools to troubleshoot problems at the development stage, and the ability to add error handling routines while writing macro code, and to provide quick fixes when users encounter errors during execution.
Developers need to identify and pinpoint mistakes while writing code and be able to make rectifications quickly.
