If I were you I would start with the basics and read about exceptions... Here's a good starting point: http://www.codeproject.com/Articles/125470/Exception-Handling-for-C-Beginners

Exactly. One important thing: handling them "for a function" is usually a bad idea, too locally. Exception should be rarely caught. They "jump" over the stack frames, which is beyond the usual call/return mechanism.

I answered the question with the links to the answers covering some main ideas.

Usually, handling them "for a function" is usually a bad idea, too locally. Exception should be rarely caught. They "jump" over the stack frames, which is beyond the usual call/return mechanism. The technology is created to isolate "regular" instruction flow from exceptional situations and their corrections.

You can find some main ideas in my past answers:
Does Exception in C# Constructor Cause Caller Assignment to Fail?[^],
where was stored .net exceptions in operating system[^].

Some of more specific ideas:
Image taken from Webcam not getting saved on the server[^],
Exception Details: System.Runtime.InteropServices.COMException: Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error:...[^],

throw . .then ... rethrowing[^],
When i run an application an exception is caught how to handle this?[^],

You can use try ... catch statement.

C#
try
{
 // do something
}
catch(Exception e)
{
// deal exception here
}
finally
{
  // this block cab be ignored
}
