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"?

View 2 Replies.net - 'Exit Sub' On DialogResult.OK Button?
Jan 4, 2011I have a VB.NET form (CopyScenarioForm) with a OK button (DialogResult property = OK) and also assigned it as 'Accept Button" for the Form.
I show this form from my main Form (mainForm) using
If DialogResult.OK = CopyScenarioForm.ShowDialog() Then
DoSomething()
End if
Now when user clicks on the CopyScenarioForm.OK button, I want to validate his entries and if invalid I want to 'Exit Sub' from the OK button's click handler but when I do that the form still closes out and DoSomething() gets executed. Is there a way to stop this and keep the form alive and only exit if the inputs are valid. I noticed, if I change the OK button's DialogResult property to 'NONE' instead of 'OK' then it doesn't cause it to close. but then how Do I know how the user exited the form to execute DoSomething().
Disabling Button Before Executing VB Code To Prevent Duplicate Records?
Feb 15, 2012I need to disable a button after its pressed so the user does not have the ability to click it again as this would replicate the process in some cases.After alot of searching I found some tips - alot of code I found I could not understand.This is what I have come up with:
On page load:
If Me.Page.IsPostBack Then
'lblDetails.Text = "disabled"
[code]....
I also read somewhere that I should use: System.Threading.Thread.Sleep(1000) to delay the process or something - not entirely sure why I would do this though.Although, the problem with my above code is that when the code behind page performs validation checks, it exits sub before executing my INSERT SQL code - so when it does this it also disables the button.I am not entirely sure if the above method is fool proof or whether it is a **** piece of code that won't work 100% of the time.On another website I found a script to put on the actual HTML page with <script> tags:
Code:
<script type="text/javascript">
disableSubmit(frm) {

VS 2010 - Threading - Button To Stop Execution Of Code
Apr 22, 2011I am working on an app and I am a bit confused w/ threading. I understand the point of threading but I am not getting when to use a background worker thread vs. a standard thread vs. a thread pool. Can someone shed some light on when to use which? Right now, I am trying code an app that does stuff initially in a sequential order and then eventually must thread (otherwise it takes forever). The problem I am having w/ the sequential stuff (and threading later) is that I need a button to be able to stop execution of code. [Code]
I did the background worker on this first sequential operation because when I tried w/ out it, the text box didn't update at all until the web page contents were retrieved. Basically, the text box change of "Starting." doesn't show up until the web page is finished processing even though the assignment to the text box happens before that code.

Stopping Multiple Timers - Stop Button To Stop Each Timer One At A Time
Feb 26, 2009Alright, so I'm still working on the slot machine. I have three timers all independently going for my three "wheels" of the slot machine.
My issue, is that I'm trying to make a Stop button to stop each timer one at a time, and I'm not understanding why this code isn't working. The logic completely makes sense, and the first "wheel" stops when I click the button, however, it doesnt appear to stop the other two timers.

VS 2010 : Use A Stop Button To Stop A Loop?
Dec 7, 2009I created a form and have the variable inputs for 4 motor run statements. Then with a start button the script starts and it is surrounded by a for next statement to loop 10 times. It works fine but if i need to stop the execution of the script with a stop button. I put the stop in a new section but of course does not work to do a motor stop. It just causes the exe to not respond till the loop is complete. Just need to be able to stop the Run1_Click button section.
Edit:I do not mind if it finishes the 4 motor run commands and then stops execution of the loop. So need to figure out a way to trigger a stop from a button on the form to stop the cycle. For the future the loop will be a variable integer input so 10 will not be the standard.
Edit::Does a ' Do ' statement sound like the thing to use? If so how and where would I place that? Have a Stop button on the form and it would stop after the 4th motor run command.

Some Code Not Executing From Inside EventHandler?
Feb 19, 2008I'm having a really weird problem with my current project in Visual Basic 2005.To make a long story short, I have an EventHandler subroutine (Clock1_tick) which triggers on the Elapsed event of a Timer (Clock1). Some, but not all, of the code within the subroutine executes correctly. Some of it doesn't execute at all, even though the debugger shows that each line of code is being read.
The overall details of the program aren't really important, but within the program I have a VB class file which can be instanced via the "New" keyword and contains a series of functions, subroutines, and properties... a typical class file. The class file is for managing sound channels..The frmMain includes a status bar with a label to display the program's current status. It also includes a public sub which recieves a string and sets the text of the status bar:
Stopping While Executing A Block Of Code

(a long text)), and then add the characters to the result string
how make the application stop and start the replacing of the next character

The count down work how I want it, there is also a pic of a rocket that move up when the count down button (Button4 - the form was set up in class as a quick example, so there was no need to name the buttons) is pressed.

Code Executing To Fast For Lbl Text Change?
Aug 23, 2011When you click a button on my form, it opens a folder dialog box & gets the selected path, then changes a label's text to state that it's starting to process the directory then it goes ahead & opens a new streamwriter & continues on into my other sub for listing directories..roblem is the label isn't changing before it does it's processing, I figure that is because it's processing to fast to actually display the text. Even if processing the directory takes a minute or more the label won't ever change, which should have happened before it started processing the directory.
