关于线程问题， 我是新手 急急 ！！！
private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
  {

  lblTime.Text = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
  string str = GetBanblance(Global_User.CurrentUser.UserName);
  Global_User.CurrentUser.UserAccountRemain = Convert.ToInt32(str);
  Refresh();
  Thread.Sleep(1000);
  }



  private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
  {
  BackgroundWorker worker = (BackgroundWorker)sender;


  }

  private void MainForm1_Load(object sender, EventArgs e)
  {
  CheckForUpdate();
  lblUserName.Text = Global_User.CurrentUser.UserName;
  // GetBanblance(Global_User.CurrentUser.UserName);
  //通道初始化数据显示

  lbltongdaotype.Text = MainForm.Properties.Settings.Default.tongdao + " 通道限制字" + MainForm.Properties.Settings.Default.phoneNum;
  backgroundWorker1.RunWorkerAsync();

  }

代码都贴出来了，希望大虾们帮忙。。。。 里面的时间和账户余额怎么更新不了呢。。。 哪里出了问题

------解决方案--------------------
在backgroundWorker1_DoWork中去获取数据
比如while(!worker.CancellationPending)
{
 //get data and compare with current data
 //if data changed
worker.ReportProgress
 Thread.Sleep(0);
}
另一边在worker的OnProgressChanged事件中加上你更新FORM的过程
