I found an article on getting a bitmap out of a file like a dll file but it uses

dim IID_IDispatch as GUID

IID_IDispatch.data1 = &H20400
IID_IDispatch.data4(0) &HC0
IID_IDispatch.data4(7) &H46

How does a GUID work?

V Also I know I asked this one before but I can't find it.

What does a Hex number mean? For example what does &H20400 or is there a way to convert it.

I know that sometimes 1= enable and 0 = Disable.

Same thing for 1= True and 0 = False

I know that 1 and 0 won't always mean that but how can I tell what the hex mean.

Before I use a code I want to understand it. I just don't go around and take code then use it when I have no idea what it all means or what it suppose to do or how it works.

That's just how I am

Thanks everyone
