Web Forms :: Backgroundworker Dont Display Data In .net With C#
Jun 15, 2010
I want to retrieve values from a function at regular intervals and display it.I have two different fucntions 1 for getting values and 1 for display.I am using backgroundworker for that.
So when i put continous loop it goes into infinite loop without displaying data.The problem is with asp.net ..
What have i done is
public void backgroundWorker1_DoWork(object sender, System.ComponentModel.DoWorkEventArgs
e)
{
if (this.backgroundWorker1 == [code]...
Now until it doesnot come out of DoWork method if doenot display data eventhought it called Display_data() method.
I removed whilke(1=1) and checked that after exiting DoWork method it displays data.
So is there any way that after data binding in Display_Data() method i can display data and then refresh the whole process at backend ?

i designed an export to excel page that uses the following code
the data is displayed in grid view and the date format is displayed as M/d/yyyy
so i added the culture en-GB to page directive to display the date as d/M/yyyy
the date now displays correctly d/M/yyyy, and the utf-8 also display correctly in gridview.
however once i export to excel the utf-8 appears scrambled
when ever i remove the culture from page directives, names display correctly, however i face again the M/d/yyyy issue.
My question is: is there a way to display date as d/M/yyyy and at the same time reading correct utf-8

I have modified the sample HomeController to illustrate I problem that I have in my real application. In my real application I want a user to not wait for a longer running background process. I found that the response is not being returned to the user until the background process has finished which defeats the purpose of having a background task. Here is my modified sample MVC 2 application to illustrate.
[Code]....
When I click on About from the home page it takes ~20 seconds for the About page to appear. If I remove the Sleep(20000) from the background task then the page appears instantly. I expect a BackgroundWorker task to run in the background! What am I doing wrong?

I have an ASP.NET site and I've been doing some work refactoring code to try to remove some long running processes (in the order of an hour) from the actual http Request by creating a BackgroundWorker and sending the work off to that to process. This was running fine on cutdown tests but when I applied the logic to the real code I found problems accessing Session variables from the code running in the Background Worker. It seems that the HttpContext object that was passed has a null session and if I ask for HttpContext.Current I get null back.
I'm assuming that this is because they are in a different thread and that the session and HttpContext.Current are both reliant on being in the same thread. Is there any way I can get access to the Session from the background worker or am I stuck with finding all the variables I need from session and putting them in an usable data structure and then putting them back in session (if appropriate) afterwards? It obviously complicates the refactor massively if I need to do this so I'd rather not.how I might do this other than BackgroundWorker processes

I have an aspx page that on a button click creates a BackgroundWorker and then calls the RunWorkerAsync method. In my aspx file I have set Async='true' but when I run the application and click the button it appears as though the page waits to refresh until the processing of the BackgroundWorker is done. How do I get control to return to the page (and have the page refresh) after the BackgroundWorker is created and started?
BackgroundWorker worker = new BackgroundWorker();
worker.DoWork += RunJob;
worker.RunWorkerCompleted += JobCompleted;
worker.RunWorkerAsync();

I wonder what the right way is to set write permission on a Folder.I am in the properties for the folder I want to set write permissions to. The folder is named "Folder1"Now when I click the "SecurityTab", I can see a listbox there wich grayed out checkboxes for "Allow" and all of these are Checked, then to the right I have unchecked checkboxes for "Deny".I wonder if this is correct now, that "Folder1" has write permissions because this line execute that access is denied to "Folder1" ?
Directory.Move(Server.MapPath(sourcePath), Server.MapPath(destPath));

In the aspx markup I would like to do the following
<%if (some_condition){%>
<asp:label ID="LabelID" runat="server" />Label 1</asp:label>
<%}else{%>
<asp:label ID="LabelID" runat="server" />Label 2</asp:label>
<%}%>
But that wont work due to the ID-clash. I hoped that it would work this way since the labels cant exist together anyway, but that werent the case. And if I use different ID:s I have to do checkups in the aspx.cs to see which one got included.
# In the real code I dont have labels, I have UserControls, but it should be the same problems, right?
# I know this is not a very pretty way of doing things but thats how things are at the moment.

So I am creating a log-in screen that is similar to that of Facebook's. In other words you can log-in but if you are a new user you can create yourself a profile quickly by filling in a few fields.
The problem I have is I want to put validators in to check that a user has completed all the necessary fields but the validators dont validate even if the user is not using that form. For example, if I filled in the create user form and pressed the create user button the page would not progress as the validators for the log-in section would say that there is no text in the username or password fields.
I was wondering if there is a way of fixing this. I thought that maybe you could write in the VB code something like:
IF btnCreateUser_Click = True
then
the required validators for the log-in section are set to true.
