Actually, I think that is the best way to do it, especially from a GUI
point of view - if you aren't allowed to use that button, it should be
disabled.
So..
try
btn.enabled := False
connect..
do stuff
finally
btn.enabled := True;
end;
Of course that's only if your socket library is synchronous (like Indy -
the one that I like & that now ships with D6), if it's asynchronous then
it's a bit more complicated, but I've had to do just that with Asta -
hourglass to normal cursor, all buttons disabled except the cancel button
(which changes the mouse pointer to the normal one in the OnMouseMove
event), and so on. It's a real pain to set everything back to normal (in
all possible situations) when it's asynchronous. Use Indy:

(also, I've never met a socket that liked being told to connect when it's
already connected or trying to connect - although I've never used a NMHTTP
component)
