Somebody shouldn't be playing at work or school. The boss might be angry...

Well I hate it too. Still, with ActiveX you can unleash the power (?) of
DirectX or OpenGL. And ATL makes it easy.

Indeed, with Lesser GPL you don't even have to release the source code of
the library. You can even sell it and distribute it around the world without
releasing anything (sometimes the author only demands an aknowledge). That's
why it is called "Lesser", because protects open source "less" than GPL.

No. GPL only protects the original source code. Doesn't matter if

You'll have to realease the original code (with its modifications) only. If
class A was the original and unique class of GPL protected A.dll library,
and then you grab A's code and put it into B.dll library which also includes
class B and C, you will only have to deliver A's source code.

If you modify A's code, you'll have to explicitly mark or comment the
changes you made. In this way, if other people uses your modified A's code
and it does crash, such person will blame you rather than the original
author. That's the main purpose.

No.
