Hello,
How can I find out if an assign exists? I've tried
if(!(flock = Lock(<assign>,ACCESS_READ)))
{
// fail
}
But this results in a requester popping up wanting me to insert the "assign"
into a drive, which if I cancel, results in a crash.
On an unrelated note, how do I make a window in which the background shows
through? I've tried installing a back fill hook, using
InstallLayerHook(rp->Layer,LAYERS_NOBACKFILL); but that doesn't seem to be
all I have to do.
Thanks,
