Hi Team - do you guys have any idea how to call windows service from windows application form ? Actually i want to build reminder application which will show popup message in Tray icon of System within a given time interval. I don;t want on daily basis user run separate application for reminder. Instead if i have window service then at the time when computer starts, windows service also automatically starts and pull the data from database and based on this, it will show popup message in tray icaon of system. Thanks in advance !!
