you can use backgroundworker report on progress has elapsed. small example:

/// <summary> /// start new worker /// </summary> void startwork() {     var backgroundworker = new backgroundworker();      //make sure worker reports on progress     backgroundworker.workerreportsprogress = true;      //we want notified when progress has changed     backgroundworker.progresschanged+=backgroundworker_progresschanged;      //here work     backgroundworker.dowork += backgroundworker_dowork;  }  void backgroundworker_dowork(object sender, doworkeventargs e) {     //do long work }  progressbar _progressbar = new progressbar(); void backgroundworker_progresschanged(object sender, progresschangedeventargs e) {     //when notified progress changed, update progressbar     _progressbar.value = e.progresspercentage; }
