Possible To Update UI From BackgroundWorker DoWork Event?
Sep 22, 2010I have seen others with a similar issue but not quite what I was looking for. In the backgrounderworker class dowork event I create an instance of a new class and call one of it's function. Previously, I had this code in a windows.form.timer tick event and would pass a delegate in as one of the parameters which would allow the function and other functions it calls within the class to call a method on the form to update a datagrid on the GUI. Is there a way to do this within the dowork event? I need this because the function I call from dowork calls other functions and I want each of those functions to log information in the GUI datagrid.

Make An Application Which Has A Feature Of An Event Calendar?
Apr 18, 2009I'm trying to make an application which has a feature of an event calendar. I am quite familiar with the MonthCalendar tool in the toolbox, but that's not really what I'm looking for. I would like to make a calendar that somewhat resembles 'iCal' in Mac OS X. If any of you use Microsoft Groove Workspaces, the calendar in that is very close to what I'm thinking of. I want the user to be able to double click the day and add new events which will show the title of the events in that day on the calendar when the events are saved. Also i would like to have the user be able to make recurring events. Is this even possible with Visual Basic '08?

View 2 RepliesData Management - Changing Current Database System, MS Access 2007 Front End And MS SQL Server 2005 Backend
May 8, 2012We are thinking about changing our current database system, MS Access 2007 front end and MS SQL Server 2005 backend to using a higher level language such as Visual Basic .Net. I wonder if this is the BEST solution for data management? Currently, among others, we have two big database programs that handle more than two hundred users and it's crashed often. That's the reason we think about changing to something that can handle these database programs effectively preferably using MS technology such as .Net.

BackgroundWorker - Calling Procedures From DoWork
Aug 30, 2009As I teach myself VB, I'm working on using the backgroundworker. Mostly I'd like to use it to update a progress bar. But here the problem I'm running into...
When I use it like this:
Private Sub TestWorker_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles TestWorker.DoWork
Dim ListText As String
For Value As Integer = 0 To 100
If TestWorker.CancellationPending Then
[Code] .....
Where GetPlayerNames() is the Sub that really contains a majority of my code, which uses a class library I wrote, and calls other functions, etc. But this just causes the backgroundworker to skip right to the RunWorkerCompleted and executes no code. It seems to me you should be able to call procedures from the DoWork and then pass updates back via the ProgressChanged event. I can't image you need to consolidate all your code into the DoWork.

View 3 RepliesDoWork's ReportProgress Not Raising ProgressChanged Until After Loop Is Done
Nov 9, 2010 I am trying to get a progress bar to update on my Form while waiting for a process to complete but could not get my progressbar control to update.
First of, I have tried to fix the problem for a day and a half now looking at various codes and examples in the forums but I'm afraid I probably do not have the necessary VB skills yet to troubleshoot my own code. I believe I will be able to eventually fix this after I am done with my VB book
I've attached the relevant part of my code below and the problem is that I can see my DoWork event firing off and changing the time and percentage that I want to pass on to ReportProgress() and the ProgressChanged handler. However, the ProgressChanged handler is not raised until after my Do Loop is done.
Imports System.ComponentModel
.
.
.
Public Class Form1
Private WithEvents TestWorker As System.ComponentModel.BackgroundWorker
[Code]....
Again, I can see the ProgressChange fire but only after my work (diagnostics) is complete so my progress bar is either 0% or 100%. In Dowork, I can verify that the progtimepercentage variable is indeed changing and ReportProgress is called but ProgressChanged is not being raised until after the job I wanted is done.
