Hi Nobody, (that sounds kind of strange, but ...)

SendMessage can have a return code though. That's the LRESULT. PostMessage
would need to have a memory location modified or something else to get a
return.

However, most of the time when I use SendMessage() I don't do a return code
because, as you say, it's not really needed. I'm talking mostly about User
Defined messages through.

I guess there is a need for it, I am just wondering how they actually use
it?

I guess I sort of get it through an analogy.
Sort of like how this board works.
If I post a message. I may not get a response.
If I send a message then, I am expecting a response.
Though this board does not support Send Message.

Post message does not require a response.
Send Message requires a response.
A Command is guaranteed, so no response is required.
I suppose that is how it is setup?

Just trying to make sense of it all.
