hey all,

i was wondering when you lookup commands in MSDN help in the description
you'll often see it say that it's threadsafe or not. i know kinda what a
thread is (needle and thread right? j/k no i really know a little about
threads, but in lamen terms what does threadsafe mean?

thanks,
rodchar

You know that 2 threads can cause problems when trying to modify the same
variable at the same time, or calling the same method which internally
modifies variables, etc. since they must lock the access before modifying.
The documentation specifies which methods are threadsafe, that is, which
methods can be called safely from a thread without writing locking
statements before making the call in the code of the thread. Normally only
static methods are safe-thread since they are stateless (kind of self
contained), while instance-methods can modify member variables of the class.

Well, just to be correct the phrase:

" modifies variables, etc. since they must lock the access before modifying.
"

should read

" modifies variables, etc. so you must must lock the access in your code
before modifying. "
