Hi

I have solution with two projects, one of them is a user control
I created public shared sub in the user control which mean to wake up the
control and start doing somthing, but when i try to call it from the main
project i get error message
"Cannot refer to an instance member of a class from within a shared method
or shared member initializer without an explicit instance of the class."
What can i do?

Thanks

If you have to "wake up" each instance of the user control you need to
keep a reference to each instance in a shared variable (I would use a
dictionary or hashtable myself). You can add an instance to the list
of in the UserControl's constructor. To remove the instance reference,
I would have the UserControl implement IDisposible and remove itself
from the list in it's Dispose method (be sure to call dispose manually
- don't wait for the GC to do it for you). Then in your shared "wake
up" method you can loop through the list of instances and wake them
up.
