vb.net - vb net backgroundworker + progress bar -


I want to automatically create the progress bar which will pop up when I ran my program ..

My program has 6 functions / sub which takes a considerable amount of time to complete the running query, it is input

It is about 1-2 minutes for the backgroundworker to handle the thread and to combine it with the progress bar

RunWorkerAsync 

  Personal Sub ButtonX1_Click (ByVal Handle ButtonX1.Click) as the System.Object, as byVal e System.EventArgs. Click BackgroundWorker1.WorkerReportsProgress = True BackgroundWorker1.RunWorkerAsync () End Sub   
  Do_work   
  Private sub BackgroundWorker1_DoWork (ByVal as the object, byVal e System.ComponentModel.DoWorkEventArgs ) 100000000 i as integer = 0 to create_tree handles for BackgroundWorker1.DoWork () localtree () Localfrek () create_combination () showresult () if I mo d 10000000 again background 1. Report progress (i / 100) end if the next ending sub   
  progress progress   
  1_ProgressChanged by Private sub background (ByVal this object As, byVal e System.ComponentModel.ProgressChangedEventArgs) Handle BackgroundWorker1.ProgressChanged ProgressBar1.Visible = True ProgressBar1.Value = e.ProgressPercentage End Sub   
  RunWorkerCompleted   
  Private Sub BackgroundWorker1_RunWorkerCompleted (ByVal as the object, as byVal e System.ComponentModel.RunWorkerCompletedEventArgs) BackgroundWorker1.RunWorkerCompleted MessageBox.Show ("Work Completed!") End Sub Handle    Troubleshooting   
     
  1.   progress bar  did not pop up  
  2.  for the second problem   
     Stop because I use  for loop  which I use in the  Do_work  event  
     I do not know the TI passed to me So I can use random integer number for  loop    , do you please correct me in my program Are not you help? Thank you very much .. :)   
     
     
     First of all, you should set  visible  ProjectBar  property> before calling  RunWorker async .  
     Second, you should compare  i mod 10000000   
     Third, if  i  goes up to 10000000 then  i / 100  going forward 100.

In brief, the wrapper module is inserted during posting and the status of an entry is changed to 'modified' .
