They are normally outside of your control but can be caused by errors in your code.For example, imagine your application reads from an external workbook.To understand error handling we must first understand the different types of errors in VBA.There are three types of errors in VBA We use error handling to deal with runtime errors.The line will still appear red if there is an error but the dialog will not appear. The syntax is correct on a single line but is incorrect when all the project code is taken into account.Examples of compilation errors are: then VBA may find compile errors when it runs. Runtime errors occur when your application is running.If we think an error is likely to occur at some point, it is good practice to write specific code to handle the error if it occurs and deal with it.For all other errors we use generic code to deal with them.
If you have used VBA for any length of time you will have seen a syntax error.
This is where the VBA error handling statement comes into play.
They allow our application to deal gracefully with any errors we weren’t expecting.
When we think a runtime error could occur we put code in place to handle it.
For example, we would normally put code in place to deal with a file not being found.
