Question

As the title says , why isn’t user-control class access not safe from another thread? I heard that there is a way to enable cross-thread access and am thinking of doing so.. Any thought why i shouldn’t ?

Take a look at this:

Access to Windows Forms controls is
not inherently thread safe. If you
have two or more threads manipulating
the state of a control, it is possible
to force the control into an
inconsistent state. Other
thread-related bugs are possible, such
as race conditions and deadlocks. It
is important to make sure that access
to your controls is performed in a
thread-safe way.
