.net - Stop Executing Code?
Dec 14, 2011I am compiling and running code at runtime. Can I stop this code midway through if I wish? Like the 'stop' feature in Visual Studio that stops the code if desired?

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"?

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
Oct 10, 2010I'm trying to replace text using this method:
Add each characted to a String list (List(Of String)), execute the replace function for every type of character (for example: Text = Text.Replace("A", "0AA") Text = Text.Replace("a", "1AB")), but there's a problem: it replaces the text, but it replaces those replaced characters too, so when I replace "A", it will result something like this: "0AAB AAA 0AB"... (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
I'm trying to use this code block:
Dim ReturnedString As String = GivenText
Dim ListToEncode As New List(Of String)

VS 2008 Code Not Executing In Right Order?
May 13, 2009i seem to be having issues with my simple count down project. 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. The problem is that the count down "10....1...Blast Off" shows after the rocket has moved up, I want the countdown text to show, then the rocket to move.The countdown is outputted to a ListBox.Here is my code thus far: (I have re-worked is a bit, starting to look messy)

I am not sure if I should be doing it as a function, that was just one of my attempts to get it to output everything in the right order.

Dec 5, 2011In my application, I have a call for an update to a table on my database.

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.

View 2 RepliesDisabling 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 To Run On 'stop Debugging'?
Aug 25, 2010When I end my app by pressing the stop button in visual studio, is there a way for that event to trigger some exit code? I'd rather do that than include a visually distracting quit button.
Better still would be to program some kind of key sequence, eg control + q to trigger some quit code so my app can exit cleanly. Is this possible? I wouldn't know how to program a key shortcut but it might be handy.
Stop Code Being Pirated?
Dec 8, 2009I've seen on here how easy it is to disassemble code and wondered what levels of precautions people here have used or would use to make the process of hacking ones hard work.
All methods i have come up with are easily worked around. simply swapping the condition for a jump in assembly code would undo even password security.
Probably the most interesting idea i have come up with would need a c module in the project that would write into memory part of the routine on the fly (i.e. it writes the conditional jumps into memory using pointers but again all that is needed is to remove the c block and write the correct code into the exe file.
The only way i have seen is to create 2 passwords one for the application and a secondary one which is stored on a server so the software checks against a serial number database, this also is limited as unmodded it cannot detect if the user is legitimate, only that there is one person using a specific password at a particular time, and in any event it is still a case of changing the conditional jumps so it works when it is the wrong password or doesn't contact the site in the first place (or another site with a valid password and allows multiple users on its database)

Completely Stop Code Execution?
Feb 6, 2012How can I completely stop code execution?
Also, how can I hide a form and keep all information saved so I can bring it back up again?
For instance, I have form1 with "alpha" written in a textbox. Now when I hide form1 (Me.Hide), I would like to be able to bring form1 back with "alpha" still written in the textbox.
Currently, I hide it, and when I show it again, the textbox is empty.
