Something like WM_COPYDATA

[Patrick Weidener]

I need to send data from my C# window to a VB6 window, and I want to do
it with WindowMessages.
The data I have is a struct that contains (among other things),
..positionX and .positionY.
What would be the easiest and fastest way to send these coordinates to
my VB6 window from within C#, please?

Well, if you insist on doing it via WMs, then why not just use WM_COPYDATA,
as your post subject says? It's not like you can't use SendMessage from C#
via P/Invoke.

Can you tell me how to get the coordinates in 1 packet?
