I'm trying to add a new feature to some software I have developed but am having difficulty. Essentially I want to add a 'Pause' and a 'Resume' feature.I have a timer which counts down.
Private Sub Timer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer.Tick
Dim togo As TimeSpan = mTestEnd.Subtract(Now)
If togo.Ticks < 0 Then
Timer.Enabled = False

When the Start command button is clicked the timer starts counting down from what amount the user inputed. I've added an elseif to pause the timer and this works ok. When I click resume the although the timer text has paused the actual timer has not and continues from where the timer would be if it had not been stopped. Much like a stopwatch lap timer. Could you help me with my Else statement.
If StartButton.Text = "Start" Then
StartTime.Text = Format(DateTime.Now, "HH:mm:ss") 'Hour(Now) & ":" & Minute(Now) & ":" & Second(Now)
txtTimeLimit.Text = HourUp.Text & ":" & MinuteUp.Text & ":" & "0"
mTestEnd = Now.Add(TimeSpan.Parse(txtTimeLimit.Text))

I am trying to find a way to resume a thread after catching the AbortThreadException and calling AbortReset.
My thread is running a loop to control two motors used in a raster scan. Once the button is pressed to begin the scan, I want to be able to click a stop scan button and have the following happen:
1. AbortThreadException is thrown and caught- a window comes up asking if you really want to abort the scan. Click yes for abort, no for suspend, or cancel to continue scanning.
2. Given users answer the program responds accordingly- If cancel, then the scan should continue right where it left off and not restart.
My problem occurs in my understanding of the thread events. I am not sure how to tell a thread to wait for a button event nor do i know how to tell a thread to continue where it left off. I also noticed that the 'suspend' and 'resume' methods have been deemed obsolete and i am not sure of the alternative way of doing those actions.
The following is the code used to catch the exception and execute the task.

I want to make my form freeze for 5 seconds before it resumes to the next form.So I have a form that says : Establishing a connection....
But I don't want it to make a connection, i just want the user to think that it's making a connection.
And I then want it, when the timer reaches zero, that it would resume to the next form.
I just need the code of the timer behavior.
I am thining of using a boolean value per each backgroundworker to flag their completion and check all of the boolean values but there should be a better way,
View 3 RepliesI am developing a Windows Service in VB2008 and am in the testing stage. What I have noticed is that if I Pause it while it is busy doing something and then resume it, the process generates an error. While I am debugging this I wanted to determine exactly what the difference is between Pausing/Resuming and Stopping/Starting a service.I searched, but most results simply told me how to Stop/Start/Pause and Resume a service, a hurdle that I jumped over many years ago. Does any one know of any resources that go into detail what happens when a service is stopped vs when it is paused?From some experimentation, it seems that if I do not place any code in the OnPause and OnContinue events the Pause/Resume commands have no effect.

I just had a new, last-minute idea on to take on a task, so I am running to StackExchange for quick help.
What I want to do is execute a series of methods right in a row, each in their own threads. I want the application to wait until all of these threads are completed, after which the program will resume. It also has to use managed threading (thread pool).
What quick examples could you provide to help me along the way? If it's too complex, what things should I know about so that I can Google it on my own?

View 2 RepliesI have an application where the admin user can create users and upload documents to the server for the created user to download.
When uploading a file it creates a folder using the userid as the folder name and saves in that folder within a folder called documents e.g. ~documents/77b29079-43d6-4520-bc34-77ae2af1b131/documentname.xls
The client then has to login and will see a list of available documents for that user only. The only problem is that if someone was to get hold of one of the urls to a document is can be downloaded without having to login.
Is there something I can do to stop access to these files?? I have tried editing the web.config file to only allow access to certain roles but i could still download a document without logging in.
<location path="documents">
<system.web>

I eyed VB.NET 2010 Express and created the damn app. It's up and running and it does what it's supposed to do (in v1). Now I'd like to distribute it for free while:
(1). Have a reliable way of knowing (and everybody can check this out) the number of downloads.
(2). The app cannot be passed from one user to another, but has to be downloaded from the reputable biz (there can be more than one biz) that accurately provides the number of downloads.
(3). I can have total control over the app (once it's downloaded by the users), that is if I want to inform the users of updates or whatever, or if I want to add some ad windows to the form I can do it whenever I want and how I please.
How do I do (1) to (3)? What am I supposed to read to do (3)? ADO.NET and ASP.NET? Any shortcut? What's the easiest way of doing it? I'm not sure I'm looking for a career in programming, for now I just want to take this app off my shoulders and go back to daydreaming.
MVC3 VB.NET Razor view Application... I have a view that uses a for each loop to display all the available courses. Next to each of these I would like to place a Html link to download that courses class handout file. Problem is I have not found anything on any forums about assigning the value to the hyperlink dynamically since it will vary with every iteration of the for each loop. I have coded the model to hold the file name associated with each class. Below is a snippet from the view..

View 3 RepliesI've just switched my code over that downloads data as bytes to use a WebClient. I add a header saying I will accept GZip and the site I'm downloading from sends me the data compressed. The problem is, how can I check to make sure it is compressed data before attempting to decompress it? It was much simpler when I was using a Web Request to check the response headers, but I'm having a little trouble checking the reponse headers with a WebClient. Does anybody out there accept compression with a WebClient?
