VS 2010 Stop A Block Of Code Executing When User Clicks "Stop"?
Mar 1, 2011
I 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"?

I need to record the screen when my user clicks start, and stop recording when he clicks stop.I've searched for a while on this subject, and I have found nothing.I want to do this without adding any files to my project, I just want to use some built in function in Visual Basic, and start recording, or even take a snapshot and add it to an AVI file or something...These are some sites I have found:

This code is in VB6, but I am not sure how to even start using it?

I 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

I 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.

I am having a problem with my try catch block runs in the error "dastabase is not available". My problem is the try catch runs and catches the error, but it will not redirect to my error page. The code continues to execute the other subs. I have tried adding: exit, return, response.end. None of them worked.

whenever I have to convert something to a value (for example,lets say I have to convert something to
a boolean) visual studios will give you their advice of CBool, which works, but that's VB6 and I do
not want that. If you know of a plugin that does it, I'm open to that as well.

I 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.

Is there any way visual studio block Port 8080 to stop the internet? I want to make an administration system and I have a functionality that blocks the internet of a computer but everytime i look for a solution in the web it is either from another language or just a discussion about network protocols. Can someone help me? I had a background of tcp/ip protocols but i really can't figure it out and convert it to codes using visual studio.

Alright, 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.

I'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)
Dim curr As Integer = 0

I am currently building a webbrowser that only loads one page, but I don't want the user to be able to navigate away by clicking advertisement links, as I don't want them to be able to surf the net, clicking links could eventually lead them back to Google to search for what they like if they are clever enough!

When 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.

I'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)

How 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.

Currently I have the start-key for my vb.net application hardcoded like this:
GetAsyncKeyState(Keys.F2)
Where vb.net sais "F2 As System.Windows.Forms.Keys = 113" on mouse-over.But I want my users to be able to pick their own Key. If I make a drop-down box (combobox) and pre-define some choices in there (Like ESC or F3), all those choices are strings. How can I convert those strings to a System.Windows.Forms.Keys integer? Also, I'd like it to also be possible to "capture" a single keypress. So they'd click the "capture" button, and the next key they hit will be saved as the start/stop button. But I wouldn't even know where to begin looking for that one.
