Pearson Software Consulting Services. Error handling refers to the programming practice of anticipating and coding for error conditions that may arise when your program runs. Errors in general come in three flavors: compiler errors such as undeclared variables that prevent your code from compiling; user data entry error such as a user entering a negative value where only a positive number is acceptable; and run time errors, that occur when VBA cannot correctly execute a program statement. We will concern ourselves here only with run time errors. Typical run time errors include attempting to access a non-existent worksheet or workbook, or attempting to divide by zero.
The Resume keyword should only ever be used inside an error handling subroutine, because if VBA encounters Resume without being in an error state, runtime error 20 "Resume without error" is raised. The On Error statement itself can use the Resume keyword to instruct the VBA runtime to effectively ignore all errors. If the error isn't actually handled before doing that, then execution is permitted to continue with potentially invalid data, which may result in logical errors and unexpected behavior. The emphasis above cannot be emphasized enough. On Error Resume Next effectively ignores all errors and shoves them under the carpet. On Error Resume Next can easily hide bugs.

A Resume statement can only appear within an error handler and can only be executed in an active error handler. This error has the following causes and solutions:. You placed a Resume statement outside error-handling code. Move the statement into an error handler, or delete it. Your code jumped into an error handler even though there was no error.
Although the next time it would be really nice to have kinda more reviewing weeks, I mean, clother to the end of the course I felt an inspitation and I needed some feedback from peers, but I couldnt get it bc it wasnt a feedback-week.
