dr watson crashes

[slugger]

hi

im using labview 6.1.

i have a frame in a sub-vi that that reads 16 bytes from com7 (in my pc) into a global variable using a custom DLL. this variable is then used later to compare some data in another sub-vi.

this was working fine for a day, then this morning i started it again and ran it. when i got to the point where this "read" happens i got a dr watson exception message. (i am running the application on nt4 in the development environment). after this point the gloabal had rubbish in it whenever i did a read, although it did also hold the basic read data. after a reboot etc it still did it. the fix was to completely remove this global from the application vi and my file globals.vi , create a new one and then use that in the same manner.

everything was ok for an hour.

then the same thing happened again.

any ideas? this is really annoying.

HI Slugger,

Some of us can't get enough LV so I noticed you cross posted this Q on the NI forum in this thread

http://forums.ni.com/ni/board/message?boar...5&jump=true

Cross-posting is OK but please indicate as much so we are not duplicating our efforts (please).

Like I suggested on the NI forum, please post example code.

Thank you,

Ben
