View 2 RepliesCancel A Task Which Is Not Performing Any Loop-based Statements?
Mar 27, 2012I have an asynchronous task that is executing a function. The function does not contains any looping statements, but instead it is executing series of sql commands on sql server. Now, i have a button on my window that can cancel these sql operations. In other words, cancel the whole asynchronous task.
I know that this technique will require CancellationTokenSource and CancellationToken to cancel the task, but i've seen many examples on the internet and all of them are showing that the function that task is executing contains loop statements in which they are checking for IsCancellationRequested boolean property. But in my case, it is not so. My function does not have any loop statements in which i can do a check on this boolean property.
Stop / Cancel A Build?
Jun 22, 2012I went to publish a new version of my game to my C: drive, got the standard "Build Started" and thats as far as it got.Now I can't do anything with the vis studio program, if I try to save - a warning message tells me this is a bad idea with a build running, trying to exit the program results in a message "A build must be stopped before the solution can be closed".
Choosing "Cancel Build" in the build menu caused the Build Started to disappear but nothing else. All other options in the build menu are inacessible.
Searching the program help and google for how to stop builds give a lot of web pages that go on about the build explorer, found in the team explorer, select the team project, etc etc - I don't have anything in the team explorer window, this project is just me and my pc.

Press Stop Debugging/ Task Manager End Process?
Feb 15, 2012When I go to Debug my program (F5), the program will load, until I click on the form with the main part of code in it, and then the program freezes, although it doesn't lock up because as soon as I press stop debugging/ task manager end process, it closes fine.
I will attach the zip of the program here. The form that it freezes on is "Black Ops". Edit Due to the forum not accepting my .Zip file (Invalid file type), I will upload it to MediaFire. Download link (445kb): Click Here

View 6 RepliesLeaving Trash Behind - Stop - Removing A Copy Of Program Shown On The Task Manager After Close
Jan 3, 2009Need help removing a copy of my program shown on the Task Manager after I close.
I must kill a conflicting program that cannot share the COM port and then reinstate when myprogram ends. To reinstate I use: System.Diagnostics.Process.Start(conflictingPath & conflictingProgram)
In the last line of my Form1.Closed I try to end all with:System.Windows.Forms.Application.Exit()
Not working - each time I run this program it does kill the conflicting program, can do its dialing function and upon closing reinstates the conflicting program. But each time another copy shows under Task Manager.

Calling Javascript Function After ASP.Net Server Processing Completes?
Jan 18, 2012Say I have a simple web app written in asp.net/vb.net. The web page has one button. When you click it, it does some junk in the code behind. What I would like to do, is when the page reloads, after the server has done its thing, to execute a JavaScript function.
Now the only stipulation is that it can only happen if the button was clicked. Not just on any page load. Is there a simple way to do this?
VS 2010 Cancel The Timer From Within The Callback Function
Mar 16, 2012I was trying to use the System.Threading.Timer to run a function every 250ms - but I'm finding it difficult to cancel the timer from within the callback function. I can't seem to find a reference to "this" (js has this - it's so nice). At any rate - how could I start a callback running 250ms from now - without a timer - and then if I want to continue it again do another start for 250ms.

Multi-threading Processing - Processing A Large List Of Records And Inserting Them Into SQL Database One By One
Mar 18, 2011I just learned some basics of multi threading in VB.net recently as I came across processing a large List of records and inserting them into SQL database one by one.
I have code look like this:

Dim autoLoad1 As New Thread(AddressOf AutoLoad)
autoLoad1.Start()
[CODE]...
Itemlists is a global lists i retrieved from database, everything looks fine to me but when i run this program, I found that the threads are inserting one records 9 times into the database(I have 9 threads in total), which makes me think that maybe i need to specifically assign 1/9 of a list to each thread? Is there another way to do it which doesn't require the splitting of the list, if not , how do i split it then assign?
2008 Array Processing And Sequential File Processing?

View 14 RepliesVB 2008 Array Processing And Sequential File Processing
May 19, 2011Im a college student and this is my first programming class, i am having extremely diffcult time with arrays and sequential file processing. Im not asking for the whole program, just something to get me started and hints along as i progress with it. Please help me get started on my program, its due in 2 days.
Here are the requirements....
1. The program must input any number of individual�s last and first names using two separate textboxes.
2. The array of names must be sorted by the last name using a bubble sort. You must code the sort.
3. The program must be able to recall the names from the file and add to the existing list of names so that more names can be added to, sorted, and written back to the file in sorted order.
4. Sort in ascending order: A to Z
5. All names must be displayed in a listbox in sorted order when the user wishes to see them.
6. In the listbox the last and first names must be separated by a comma and a space. Example: Smith, Mary
7. The user must be able to search for a name in the array, using the binary search algorithm. You must code the search.
8. Do not use module-level variables. Instead you may choose to use Static.
9. The program must be designed using Visual Basic 2008

Find Function Does Not Find Last Occurrence
Dec 12, 2009I have a rich text box with the following text in it:
word word
I am finding the endings of the word, that is, the string "rd". The following code finds the first occurance, but then fails to find the last occurance, and the variable "indexToText " changes to -1.After the first search, the debugger shows the startLocation at character position 4, so it is not past the second occurance but still will not find it.
indexToText = FrmMain.RichTextBoxPrintCtrl1.Find(searchValue, _
startLocation, eof, RichTextBoxFinds.None)
If I change the text to:
word word word
It then finds the first two occurrences and fails to find the last occurrence.No matter how many words I add, it always fails to find the last occurrence.

I'm using the function keys to pull up menus for selecting other media and if I do anything with the control panel I can no longer display the menus.
