The first time you will encounter errors in your application is when you are
still testing your application in the VB IDE.
No matter how careful you are in coding, you will always find something that
you did incorrectly—or a condition you did not anticipate—the first time you
run your application. How you want to handle these errors when you run in the development
environment depends on several factors. You might want to stop your application and go into
Debug mode every time your application generates a runtime error. You may also want to bypass
runtime errors or allow any error handling that you have already coded to take control.
Visual Basic provides several different options for you to use in the development
environment. These choices for handling errors impact your application only while you are in
the IDE and do not affect an Executable created with Visual Basic. The choice you make depends
on how complete your code is and the type of application you are developing.
