vb net update progress bar backgroundworker thread

I don't know the elapsed time of each function that i have, so i use random integer number in for loopĬan you please help me to correct my program? thank you very much. RunWorkerCompleted Private Sub BackgroundWorker1_RunWorkerCompleted(ByVal sender As Object, ByVal e As ) Handles BackgroundWorker1.RunWorkerCompletedįor the second problem i think it because the for loop that i use in Do_work event

ProgressBar1.Value = e.ProgressPercentage ProgressChanged Private Sub BackgroundWorker1_ProgressChanged(ByVal sender As Object, ByVal e As ) Handles BackgroundWorker1.ProgressChanged RunWorkerAsync Private Sub ButtonX1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonX1.ClickīackgroundWorker1.WorkerReportsProgress = Trueĭo_work Private Sub BackgroundWorker1_DoWork(ByVal sender As Object, ByVal e As ) Handles BackgroundWorker1.DoWorkīackgroundWorker1.ReportProgress(i / 100) I'm using backgroundworker to handle the threads and combine it with progressbar

My program has 6 function/sub which run query that took quite long time to completed, it's approximately around 1-2 minutes regarding input Thank you in advance.I want to create automatic progress bar that will popped up when i ran my program. I've Googled and read several articles regarding the BackgroundWorker Class and Multi-threading, but haven't found anything that pertained to an entire form. Invoke ( New MethodInvoker ( AddressOf IncrementPB)) Else ProgressBar1.Value + 1 ProgressBar1.PerformStep () ProgressBar1. What I would like to do is be able to open the BOM form after the user clicks the Process button and have it run in the background while all of the other stuff is processed, then have the BOM form show after everything else has been completed. The Sub that increments the ProgressBar Value: VB Private Sub IncrementPB () If Me.

During the printing of the report, I update the progress bar once per each loop through the data set. Among the things in that class are places for the progressbar and label. The BOM entry takes the longest (about 30 to 45 seconds) because it loads a form that reads all parts belonging to the BOM and shows them in a TreeView to give the user the ability to select at what level the part should be inserted. I have a special class that is located in the printing dll that is accessible from the desktop application. I've got a program I've written in VB.Net that allows a user to load in several CAD parts into a ListView and perform several tasks like copy parts to a directory for nesting, create IGES files, create PDF's from drawings, and input part data into AS400 databases (BOM). I'm new to the BackgroundWorker Class and Multi-threading, but I think something like this is what I'm needing.
