c# - can we access form controls from an external assembly (dll assembly not within the project)? -

i have access label control of running form referenceed assembly change label text dynamically.my application scans files of selected folder.i have show name of file in progress.

can access form controls external assembly (dll assembly not within project)?

your dll trigger event e.g. fileprocessing whch has information passed (current filename etc) c# application subscribe , way dll doesn't have know application using it, , application can update label each time event raised...here's overview of events c# on msdn
