Event structure crashes in LV7

[Wiebe@CARYA]

Hi,

Has anyone experienced crashes with the event structure in LV7? When we
ramble on keys a lot (we're making an arcade game) it crashes LV. The OS is
XP.

Thanks,

Wiebe.

This is expected behavior. If you refer to Kb

you will notice that they note, that if events fire faster then LabVIEW can handle them, it will crash.

Hi,

The link you've send doesn't seem to describe any crashes. We don't use user
events, just the normal VI key down and key up. Also, in LV6.0.1 and LV6.1
it doesn't crash. LV7 is robust, but this crashes LV7 completelly (not just
a message). The behaviour might be expected, it sure is not desirable. Any
application whith an event structure in it might crash when too many keys
are pressed... What should we tell customers: "don't type to fast, or it
will crash"??

Tanks for the reaction,

Wiebe.

There are not enough information about your problem. Usually I also have a lot of crashes during development, but in most cases in my code...

At the first, be sure, that crashes are reproducible. Then reduce your block diagram step by step up to simple VI, which contains error. And then, if problem still present, send your example (must be as simple as possible) to NI. May be in next version this problem (if exists) will be fixed.

good luck!

Hi,

We're developing a small arcade game, that uses a AIO module for the
movements, but it also reads the keyboard. The crashes appeared, but are not
a problem (a game should be played with the aio joystick). The event
structure was isolated. I'll see if I can send the code later this week.

Thanks,

Wiebe.
