Help (Timed program)

Question

I�ve done this game, that if the user takes more than 30 sec. to answer, the program, when the user answer, tells that the time has been more that 30 sec. so the answer is not valid;
I would like that the program, during the time the user is answering, displays the time passing and when it reaches 30 sec. it stops and says to the user that the time has passed, and that there is no more time, so the correct answer would be (for example) **-;
Does someone knows how to do this?
Thank�s for all your posts!

Hi,
Which hardware are you using??
Nevertheless, you will find an example VI with examples shipped with labVIEW called "temperature system demo.vi" a simulated temperature measurement program.
replace the temp simulation with hardware thermocouple acquisition VI's
That VI it might suit your purpose
find attached that VI
Any doubts, do get back
regards
Dev
