Why is the function body in the .h header file?

[frog_jr]

This is probably a common question, but I have not found an answer to it.

I'm using ms Visual C++ .NET (standard) for some personal projects...

When I double click on an event in a properties view of a form component (e.g. a button Click event, or a textbox TextChanged event) I am presented with a funciton body in the .h file for the form into which I can place the code for the event.

I "expected" that the function body would be placed in the .cpp file.

Am I missing something, or is there a configuration I have missed?

I would like to join you & ask the same question: WHY???????????

Poor design.

OK then,

From some of you that are veteran VC++.NET coders how do you handle this?

A) Leave the definition in the .h file (with the declaration)
B) Move the definition to the .cpp file

Maybe I ought to post this as a poll!

What are advantages/disadvantages to each of these?

Leave it in the .h file.

I actually like it. It means I can change my code, without having to always keep function definitions the same in the two files.
