Halting Program Execution With A Button?
Nov 25, 2010
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()

I have two applications. For performing certain functions, i run a second exe, via a process, and wait till it is complete (exited) to continue with my main application. I run through many repetitive functions on different files.Everything runs fine however, when i am doing a run and it is on the x loop number, the main application seems to halt the secondary process exe. I can only assume this is what is happening as, if i close/stop (not pause) my main application in VB, the second exe continues from where it was halted until it completes.

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.

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?

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?

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.

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 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.

My program keeps crashing every time I try to run it on another machine other than my own dev system. It runs just fine on mine but crashes on everybody else's when I install and run it. To make matters worse, it only gives me the generic "[name here] has encountered a problem and needs to close. We are sorry for the inconvenience". So i never can find out why and where it is crashing!!!!

I've written a keydown event that needs to occur multiple times during the execution of a program, and it needs to play a sound each time. The first time the keydown event is triggered, the sound plays without a hitch. However, the second time (and all subsequent times) the keydown event is triggered, a system beep accompanies the sound. I'm using Studio Express '10 and I've already integrated e.SuppressKeyPress into my code:

FIRST = arguments checked against each other
SECOND = arguments checked against each other but are irregardless of the FIRST arguments.
If (FIRST and (FIRST or (FIRST and FIRST))) OR (SECOND or (SECOND or SECOND or (SECOND and (SECOND or SECOND)))) then As the program processes this line over a million times during the execution, only FIRST or SECOND section is needed during an execution, never both. How do I make the program use only the section that's needed for the current execution instead of checking every argument every time? Is there a way to turn a string into an argument list for an IF...THEN statement? [code]

I�m having trouble with my VS. It gives me the error "insufficient memory to continue the execution of the program". This is a dangerous error because I cannot save the project either. So all work is for nothing. Actually VS destroyed my mainform at one time due to this error.
Now there shouldn�t be anything wrong with the computer or the project. The computer is new and with ok performance. The program runs ok on other computers (up to 5 yrs old) both published and in debug. On the old computer I use VS express, on the new I have Pro.
I think it has something to do with the graphics (I have added one or two pictures to the project since testing it on the older computer). VS graphics really doesn�t work like it should.
I have a mainform (the one that got destroyed) which I want to use as a MDI container. I want to have a picture as background. That doesn�t work (!) so I use a picturebox instead. When showing childforms the idea is that som part should be transparent, thus showing the MDI�s background.
In debug, as well as after publishing, the result is the MDI shows, and it actually has the picture as background. However the childforms don�t show at all. They show up in the window toolstrip though. Needless to say I cannot save the project because of the memory issue.
So, am I right in assuming that VS cannot handle a simple .bmp picture, or what should I do to be able to continue developing?
