Error handling is the process of handling the possibility of failure. For example, failing to read a file and then continuing to use that bad input would clearly be problematic. Noticing and explicitly managing those errors saves the rest of the program from various pitfalls.

What is error handling in VB?

1. You need to Set objects since this is an object.
2. In the For loop you should be looping on objects.count not obj.count.
