I 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.
I have ...

I've just completed my first multi-threaded task under windows. Historically I am a VMS Engineer. You could multithread in drivers in VMS but VMS never had formalized threads. Which means it never had applications threads. Threads will become increasing important in the future. I thought this maybe a good time to discuss them. Not having access to sources hurts in terms of the amount of depth one can achieve in Windows. Some of the topics for this thread might be...compute resource regulation, how to do multi-threading and of course things to watch out for.

What I need is a code that can read from database (*.accdb). Form example if I select LG from Form4, it should read from a table from the database the price of
the LG, then we press "save", then should return to the Main Menu, then we select, for example, Scanners from the Main Menu that will take us to Form5. There we select, for example 24", that should take the price again from the data base and
add it, after save, to our first LG price, and return back to the Main Menu, and so on. The total price should appear in a new form, form7, after clicking (Total Price).

View 3 RepliesRules:
Rule 1: Replace all of the vowels (A, E, I, O or U) in the original password with a number as follows: (20 points) Replace the first vowel with the number of 1. Replace the second vowel with the number of 2. Replace all other vowels with the number of 9.
Rule 2: Replace all of the numbers in the original password with the letter Z. (15 points)
Rule 3: Reverse all of the characters in the original password. (10 points)
Rule 4: The enter password should be non case-sensitive. All the letters in new password should be in upper-case. (5 points)
This is what is should look like:

CODE:
Right now I'm not worried about the efficiency of the code (i.e. simplifying code into fewer lines). The problem I am having is the locating and replacing of the vowels. When running the program the code will replace all of the numbers with "Z", reverse the string, and make all letters uppercase. When it comes to locating the vowels, the program squares the number it goes through the string by the number of letters that it contains. I don't know why it does this.
when the string contains more then 1 vowel the first time it goes through it replaces all vowels with 1, then goes through again and replaces all vowels with 2, and goes through again repalcing all vowels with 9. These are all then combined into one string.
The research I have done has only turned up how to replace vowels with one thing (i.e. all vowels become "*")
what's the best way to stop a form from displaying in its Load event.I initialise a form using the following code:
Dim MyForm as new MyCustomForm
In the Load event of MyCustomForm, I ask the user to select a folder and use that to populate a listbox on the form.folder.If the user presses Cancel instead of selecting a folder, I don't want to display the form. Right now, I just call Me.Close in the Load event, but that still causes the form to briefly appear and disappear in the background. Also do I need to call Me.Dispose?
In a vb.net windows application, I need user to confirm before closing application. I have this code in FormClosing event

I have a Visual Studio, Visual Basic form that includes an OK button and a Cancel button.
What I want to do is have the OK button save the options that the user chooses and of course the Cancel button discarding them and returning them to their previous values.
But what I'm noticing is that as I'm debugging the form, the values are being saved regardless of whichever button I'm choosing. On the form's properties, I have declared that indeed the CancelBtn is the CancelBtn and that the OK button is the OK button, but the values are still being saved regardless.
Is there a better way to do what I would like this form to do?
EDIT:
Here's the code so far for the two buttons, both are being set to close the window. AcceptOption should save the values and CancelOption should just close the form. I'm sorry if this isn't done well but the FAQ's that I found only mention changing the properties of each button and nothing about the code.:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles AcceptOptionBtn.Click
