To Check if the object is alive

[kais]

Hi all,

In my vb application, i am creating an instant of the DLL, it is possible that the DLL may get hang and this makes my application as not responding.

How can i check for the object is responding or not, or it has gone hang???

Any idea how to check this...



Thanks in advance

If you have the thread ID, you could presumably send the dll an
appropriate message (SendMessage) and wait for a response.
With no response in X timeframe, I should think it would be
appropriate to assume that it's hung up.

Of course, you should also examine the possible places for hang
up, and attempt to guarrantee that any potential hang up is
taken care of.

If you've written the DLL, then you probably don't need me to tell
you of the potential hangup points.
