There are VIs on the NI ftp site for reading the keyboard. You log into
the ftp site at ftp.natinst.com with account as anonymous and password
as your email address. Then cd to support/labview/vis/windows/31 or
something close to that. They will work for versions 3.1 and greater.
Another neat trick, the user can't type into anything else on the panel,
is to make two string controls. Use the attribute node to set the
key focus to one control, and then the other at say 50Hz. Then read the
terminal for the controls and see
what their value is. Swapping the
focus will force the entry of pretty much each key, and you can then
check each for a space or whatever key you are looking for. This trick
isn't really ever useful since the keyboard VIs exist, but like I said,
it is a clever workaround.
