Executing Same BackgroundWorker Several Times Depending On Condition?
Mar 20, 2012I used BackgroundWorker to solve a problem in my winforms application, I wanted to be able to cancel a long-running operation and see results live in ListBox while executing the operation. It works fine except when I want to add a checkbox with additional condition. The problem is when I want to run several operation at once. Ex. both XX and YY executing XX first and then start with YY in that order.
Private Sub UpdateDB_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTestAll.Click
If cbxTestYY.Checked OrElse cbxTesteXX.Checked Then
SetBusyState(True)
If cbxTestXX.Checked Then
[Code] .....
I know I am trying to run multiple tasks on same backgroundworker which is not allowed, but I don't have any idea how to solve this so it runs in specific order.

View 11 RepliesVS 2010 Backgroundworker Error Only On A Condition?
Feb 16, 2010I cannot figure this one out.. I have a background worker that will perform a task streaming data from some webpages. this data is then passed back and displayed in a gridview. It has been working fine.
I've recently implemented a listbox, which its values will be passed into the function that the background worker will perform as parameters, originally i had taken a single value from a textbox.
Now, I thought maybe it had something to do with the listbox, so I used a static value, just a simple String, as the parameter, and again, I get the TargetInvocationException was unhandled.. There's no difference in how I perform the task I'm trying to have the backgroundworker complete, the only difference is where it exists in my if condition statement:
Private Sub BackgroundWorker1_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles ScrapeSites.DoWork
Dim results As ArrayList
Dim worker As System.ComponentModel.BackgroundWorker = DirectCast(sender, System.ComponentModel.BackgroundWorker)

VS 2010 For Loop Condition Met Not Working
Oct 28, 2011I have a list of string in an array. I'm loop through those strings and if the text of a combo box matches one of those strings, I want a message to appear. If they don't match, I want a method to be executed.
[CODE...]
The messagebox appears, but the method is still executed. Which means it isn't stopping when it finds the match. I tried exiting the loop, but it still doesn't work.

VS 2010 - Prevent Sub From Executing Multiple Times?
Jan 28, 2011I have a button and various other controls that when clicked, calls as sub. However if the user clicks the button or any of the other controls multiple times, the sub appears to 'stack up'. For example, if I click the button 10 times, and then some of the menu items that trigger it 20 times, the sub would 'stack up' and execute 30 times total. How can I have the sub cancel calls to itself if its called again? I basically only want the latest call to it to count.
Heres code to reproduce it. Just a button on a form.
Dim intTotalTimesClicked As Integer = 0
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click

VS 2010 Stop A Block Of Code Executing When User Clicks "Stop"?
Mar 1, 2011I have a START and STOP button and when the user clicks "start" the program does a whole bunch of calculations and all. However, I noticed that when I was testing the program I clicked STOP the program continues to execute stuff.
My START code is basically a while loop that iteratively does some calculations.
So I just put a boolean variable as the while condition and when user clicks stop its set to false and when user clicks start its set to true. However, when I click stop, the condition is set to false yes but it still executes all the code until the condition is re-evaluated right...so my question is how can I get out of the while loop when user instantly clicks "stop"?

SQL Group By With A Condition?
Aug 16, 2011Scenario: I need to create a report for the auditors for an ASP.Net application. I have a program that parses the XML of the web.config files in a directory for the authorization tag and creates a report providing which users have access to which folder in the site structure. The report is shown below.
UserName, Firstname, LastName, Directory, Roles, Access,
LastLoginDate
Problem: As you can see from the report some directories (the middle column with GISMO in it) show up twice, with both allow and deny for a user. I am wondering if there is a way to group the results in such a way that if there is a row that has allow for a directory then the deny's are not shown but otherwise they are.
Alternatively if this can be manipulated in VB.net/C# that is also an option. It comes back there and is pumped into an Excel spreadsheet.Edit: I should have explained better. I still need the deny rows to show if the user isn't allowed in the directory. But if they are allowed then there is no point showing the deny rows.
