Hi,
How can I make a sub to be executed only one at the time in a multithreaded
environment?
Eg, I have "server" thread,s that does printing, problem is when several
server threads running at the same time, the Crystal Reports Com Object
crashes, Guess its not thread safe..
How can I change so my "PrintReport" sub only run one at the time, if
another thread is requried to use it, it need to wait until the first is
done.
( I see how I can do it with a global boolean and some do while loops, but
is there any built in functionallity for this kind of operations?)

Use SyncLock Statement
Private Sub PrintReport()
SyncLock "PrintReport"
'Printing
End SyncLock
End Sub
