Hello,
I am making a Pascal wrapper for a library, which states in its API description:
"
Note that the Callback function will be called from an independent child
thread, not from the Applications Window thread. It should not therefore be
used to draw data directly to a Windows screen. The safest use of the callback
is to use a threadsafe interface (such as Windows messaging) to pass the
message to Windows for handling by the Windows thread.
"
AFAIU: The callback is just a callback. So you can handle it in the
normal way (either in an application, in a command line tool without a
main form or in a dll.) You just can't do any GUI stuff in that callback.
I understand that you in fact don't want to do that, anyway.
