Stop a search that's in progress, typically as a result of a timeout or because the user
has cancelled the search. Returns true if the operation was successfully stopped;
if the operation lacks the facility to stop itself, it should instead return false, in
which case the thread that FindResults was called on will be stopped.
Namespace:

Assembly:
geobase.net (in geobase.net.dll) Version: 4.99.0.0
Syntax public override bool TryCancel()
Public Overrides Function TryCancel As Boolean
Return Value
Type:
BooleanWhether the operation stopped itself.
Remarks If the operation involves use of unmanaged code, it is important that the
operation can stop itself. Otherwise, cancelling a search may result in memory leaks.
TryCancel does not need to guarantee that the operation has stopped before returning
when it returns true; it merely needs to guarantee that the operation will stop
imminently.
Subclasses of RelativeSearchOperation should ensure they call base.TryCancel if they
override this method, which will cancel any inner search that may be running.
