Hey all, first off I'm new round here...so...hello.
Back to the question....
Yep, just finished a project like this...first you need a server, right? If
you have access to a server, you need to write a quick little server script
in something like perl,asp, or java (depending on your server OS and your
knowledge of server-side programming) that gives responses to your
projector. If you've got the server side down pat, you can use Lingo's
method -
aVar = getNetText("http://serverName.com/userCheck.asp?userid="&user)
where user is a Lingo variable that you have the user fill in. The short
point is that the server responds to this just as if you had typed it in a
browser. In your server script you can have it spit out a 1 or 0 (or another
response like TRUE or FALSE) if the user name was valid or invalid. Then all
you need to do is check
netTextResult(aVar)
for 1 or 0 and handle the situation accordingly. Here's my exitFrame code:
on exitFrame me
if shouldCheckUser then
if checkedForUser = FALSE then
user = gUserName
-- put user&"!!!!!!!!!!!"
gNetID = getNetText("http://serverName/userCheck.asp?userid="&user)
checkedForUser=TRUE
else
put "checking for status"
if netDone(gNetID)=TRUE then
if netError(gNetID)<>"OK" then
put netError(gNetID)
alert("There has been a network error")
destination = "packageComplete"
else
put "we're good to go"
serverResponse=netTextResult(gNetID)
put serverResponse
if serverResponse contains "TRUE" then
put "authorized"
destination = "DownloadFile"
else if serverResponse contains "FALSE" then
put "denied"
gTries=gTries+1
destination = "invalidPassword"
end if
end if
else
put "waiting"
destination = VOID
end if
end if
end if
if destination = VOID then
go to the frame
else
put destination &"########"
go to destination
end if
end
The database thing is a bit more complicated to deal with, but this method
of sending information to a server and getting responses is pretty common.
Let me know if I need to explain this more, I'm typing kind of quick here :)
