Error catching is the most important process for predicting, finding and correcting coding errors. Even with the maximum reduction in the number of errors in the program, there will certainly be cases when errors do occur.
Bug trapping means predicting, finding and fixing programming errors. Even with all efforts to reduce the number of bugs, there are bound to be cases where bugs will be created in the program.
A good programmer should be especially attentive to parts of the device that can cause errors, and should compileWrite error handling code to help the smoker troubleshoot. Writing code-affecting errors is good practice for Visual Basic 2010 programmers, so don’t try to quickly exit your program by forgetting the error handling code. On the other hand, there shouldn’t be too many bugs when working with the code in the program because it creates problems for the programmer to make sure you maintain the program and fix bugs later. error handling capabilities compared to older versions of Choice VB.
For example, if a worker tries to divide a number by zero, Vb2010 will not return an error, but “infinity” (although this is mathematically incorrect, since this element should not be set)

What are the types of error in VB?
In Visual Basic, errors fall into three categories: syntax errors, runtime errors, and logical errors.
Try [ try_statement(s) ] [Exit attempt][catch [exception name [as type]] if [expression] [catch_statement(s)] [ Exit Try ] ][ plug ... ][ Finally [ ] final_declaration(s) ]end of attempt
The try/catch block must surround the code that might throw the exception. This is the so-called secure code. You can use a combination of catch statements if you need to catch different types of exceptions.

Try/Catch statements separate normal code from the error handling system. Let’s show how to handle exceptions with Try, Catc keywordsh and finally.
