Hi,
If i have a remoting component hosted on a server that exposes a method that
does some file IO operations, and i want to avoid this method to be run at
the same time from client applications to avoid file locks, can I use
synclock before the method is called from the client app to achieve this ?

Niclas,
The code running on the server would need to do use 'Synclock' or one of the
other locks found in the System.Threadin g namespace.
SyncLock uses System.Threadin g.Monitor which locks the object locally (on
the client). The 'cost' of having Synclock locking remotely would be too
high, as SyncLock is used to keep two thread synchronized.
Hope this helps

Hi, SyncLock is only for your threads running in your assembly and the
objects exposed in your assembly.

Tom,
I am not sure i understand, should i use synclock in my threads on the
client side when instantiating the remoting object ? or is synclock to be
used on the server side
Thanks for helping out

It can't be used for what you are trying to do, if you see Jay B. Harlow's
post, it explains how Remote SyncLocking is a great strain on resources, and
can't be implemented easily. The VB SyncLock is only local, and cannot be
used for what you are trying to do.

Niclas,
You can use a synclock on the client side, only one client will honor them.
If you want to use synclock for the 'remoting object' itself, you will need
to use it on the server side itself.
Hope this helps

I have some questions about whether synclock is necessary in a few
different scenarios:
1) I have a Queue class which is shared between two threads. Thread 1
pushes objects onto the queue and Thread 2 pops objects off the queue
one at a time (with no enumerators - just first in, first out). Does
the Queue class need to be synclocked when objects are pushed on or
popped off?
2) I have a boolean variable which can be read or written...
