Stop Execution Of A Program Without Ending Application?
Jun 15, 2011
I have written a converting program, which converts binary files to ASCII files. (VB.net 2010). I need to have a functional "stop" button on the form and I was wondering if there was a simple command to make a program stop, exit all procedures, and wait for user input on the form.
It is not feasible to multithread this application, as it frequently interfaces with the form. Currently, I have a global boolean variable which becomes true if the stop button is pressed, and I have internal loops checking to see if the variable is true. However, I don't to waste CPU on checking a variable if it's not necessary.

Is there a command that will stop the execution of my program?
I have a service that is processes an exchange account via telnet every 10 minutes. During one point of execution the application could possibly have a response from the telnet session when there are NO e-mails in the folder, which would look something like this[code]...
So is it possible for me to just stop my application at that point since there's no point in continuing if there are no e-mails in the account?

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.

I need to stop the execution of a program in VB.net. Within a repeating structure the program checks whether a variable is true or false. When the variable is false I need to stop the program execution. I do not want to close the program but simply stop it. One way I found was raising an exception, but I would not want to display the error message to the user. What is the best way to do it ?
Do
If myvariable=false then
throw new exception... 'Silent exception
end if
Loop until ....

my application has integrated an external library with long running math-evaluations. It happens that some calls to functions in this library start but do never come to an end.
Unfortunately I have no chance to look examine the behaviour of the library. So I got the idea to stop my function calls to the library after a timeout.
Has anybody an idea how to manage this an to control the execution of a function, i.e. to stop it hardly after a certain time?

I have a vb.net application that uses threads to asynchronously process some tasks in a "Scheduled Task" (console application).We are limiting this app to run 10 threads at once, like so:
(pseudo-code)
- create a generic list of 10 threads
- spawn off the threadproc for each one
- do a thread.join statement for each thread to wait for the longest running one to complete.
What i am finding is that if the code called by the threadproc contains any "Debug.Writeline" or "Trace.Traceinformation" statements, the thread hangs. I can see the thread in the Debug - Windows - Threads window, and switch to it, but it highlights the debug.writeline statement and never gets past it. is there something special about the Debug or Trace statements that make them non-thread-safe? Any idea why this would hang things up? If I leave the debug statement in, the thread never completes. If I take the debug statement out, the thread completes in less than 5 seconds.

I am checking to see if a textbox contains a number, or is null. If it is non numeric or null a message box appears asking the user to input the proper value. When the user clicks OK on the msgbox the program will continue to execute the code. I want it to stop executing the code and revert back to its default state as it would be if you just opened the program. What is the command for doing this so I can add to the if statement?
Dim numCheckV as boolean
numCheckV = IsNumeric(Vinput)
If numCheckV = False OrElse TextBox1.Text = "" Then
MsgBox("Please enter voltage!")
End If

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.

I'm writing a class library and I need to be able to shut down the main code in certain cases.
I know I could raise an event and listen for it in the form called by application.run but I would like to find a way around it.I wouldn't be opposed to try to throw an exception that if unhandled would close the application... but would prefer to come up with a more elegant soln.

I'm attempting to display records on the screen 30 records at a time. When totrec is greater than 31, I was hoping the program execution would stop at the line "btn30to60.Focus()".Instead, execution continues and the sub "between31and60" is executed.If anyone has a simple way to halt program execution until the user clicks on the button "btn30to60"
Code follows:
If totRec > 30
And totRec < 61 Then
Call lessthan31()

My Application (Vb.net, Access 2003/2007) is to scan Access Database files for activex controls and to generate report accordingly.Problem:
Getting an error like:"Insufficient memory to continue the execution of the program."
The above error occurs while scanning for older version of Access files like prior to office 2000.
And the line of code where I get this is as follows:
Dim oForm As Access.Form Dim oAccess as Access.Application oForm = oAccess.Forms(objForms.Name)
But it opens the file and form as well.
Whether it is possible to read the file (Access Forms and Reports) or not?

I feel like the answers I seek are rather obvious so I feel silly for having to ask, but I just can't seem to figure this out (I'm new to threads, and am really only comfortable using them in Java at the moment). I have an Excel Addin application created with VB.NET, and I've noticed that occasionally while it's running some code (it's no one specific block of code) the program execution will just stop. This is especially problematic when I've set ScreenUpdating to False for Excel because the users then have to completely close out of Excel to get ScreenUpdating to true.

I have this on the form load;
Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.Visible = False
Me.ShowInTaskbar = False[code].....
Notice: I used "End", to terminate the process.What I want to do is when the last function is called (Delete_AutoReq_PracNo) it terminates the execution of the application.
Reason...I'll schedule this application to ran from MS SQL Server at night. So realistically, doing all the processes I would like it to stop...Is what am doing sufficient to stop the application from running or there is a more robust approach..

I only know how to add your program to windows task scheduler to schedule automatic execution but what if you wanted to have a particular thread run on a weekly schedule. Someone mentioned windows powershell for all these types of scripting; but it seems too hard to learn on short notice.

I m using access database and vb.net. My problem is that execution of program stops at third and sixth ExecuteNonQuery() methods because they are of string types and i am not able to understand the cause. I have also tried a single insert command but it gives syntax error so I used separate insert commands. The rest of the values are getting inserted properly.
