Update progress bar from for loop

Question

I am processing some xml files in for loop and according to the number of files has been processed I want to show the progress bar. Suppose there are 100 files in directory

Answer 1

Take a look at BackgroundWorker class, particularly, at ProgressChanged event.

Answer 2

for(int i=1;i<linecount;i++)
{
 progressBar1.Value = i * progressBar1.Maximum / linecount;  //show process bar counts
 LabelTotal.Text = i.ToString() + " of " + linecount; //show number of count in lable
 int presentage = (i * 100) / linecount;
 LabelPresentage.Text = presentage.ToString() + " %"; //show precentage in lable
 Application.DoEvents(); keep form active in every loop
}

Answer 3

You should use BackgroundWorker combined with a ProgressBar control. Here is a simple example.

Answer 4

Process the 100 files using a Background Worker, call ReportProgress every iteration, hook on to the Process changed event of the backgroundworker and update a progressbar accordingly.

Answer 5

Set Minimum and Maximum and then use the Step property with the PerformStep method to increment the value of the ProgressBar.

 progressBar1.Step = 1;
 int part=someList.Count / 100;
 ....
 .... 
 //Inside the loop 

  if (loop_counter % part == 0)
  {
       progressBar1.PerformStep();
  }
