BackgroundWorker(백그라운드워커), ProgressBar 활용

[BackgroundWorker]

BackgroundWorker는 별도의 쓰레드에게 일을 시키기 위해 사용하는 클래스.

[ProgressBar]

ProgressBar는 작업진행이 얼마 되었는지 보여주는 표시바이다.

public frmAutoGetList()

{

InitializeComponent();

bworker.WorkerReportsProgress = true;

bworker.WorkerSupportsCancellation = true;

bworker.DoWork += new DoWorkEventHandler(bworker_DoWork);

bworker.ProgressChanged += new ProgressChangedEventHandler(bworker_ProgressChanged);

bworker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bworker_RunWorkerCompleted);

}

//실행버튼

private void cmdEx_Click(object sender, EventArgs e)

{

bworker.RunWorkerAsync();

}

//취소버튼

private void cmdCancel_Click(object sender, EventArgs e)

{

bworker.CancelAsync();

this.Close();

}

//백그라운드 실제 처리할 작업

private void bworker_DoWork(object sender, DoWorkEventArgs e)

{

//백그라운드로 처리 할 코드 기입

//bworker.ReportProgress(숫자);

}

//작업 진행률 표시

private void bworker_ProgressChanged(object sender, ProgressChangedEventArgs e)

{

pBar.Value = e.ProgressPercentage;

}

//작업이 완료

private void bworker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)

{

if (e.Error != null)

{

MessageBox.Show(e.Error.Message, "Error");

return;

}

}
