Nov 25, 2010I'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:

Insufficient Memory To Continue Execution Of Program
Oct 30, 2009Error 1 Problem generating manifest. Insufficient memory to continue the execution of the program. Facsimile_XP
View 4 RepliesInsufficient Memory To Continue The Execution Of The Program?
Aug 14, 2009My 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?
Stop A Program During Execution Any Other Way Than By Throwing An Error?
Aug 19, 2009Is 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?
Stop Execution Of A Program Without Ending Application?
Jun 15, 2011I 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.

View 2 RepliesVS 2010 Thread To Check Main Program Execution
Apr 27, 2011I 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.

Visual Studio 2010 - Diagnose Program Crash During Execution?

Program Use Only Section That's Needed For Current Execution Instead Of Checking Every Argument Every Time?
Dec 6, 2009FIRST = 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]
Error "insufficient Memory To Continue The Execution Of The Program"
Jan 20, 2010I�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?

View 11 RepliesUsing A Cookie / Session Instantiated By Another Application?
Mar 13, 2012I have a customer intranet (ASP.NET / VB) thats instantiating an asp.net session checking various things in the dblogin process. The Intranet has various sub-systems.The marketing sub-system requires an app_role to be assigned to the Intranet user for them to view the section.I need to create a new booking form for this section but the code appears to use a generic form which is use throughout the site in various other sections. So its not a good idea to ammend what is currently there.Create a new application in C# / ASP.NET and also in IIS. (rather than a new site, create an app within the Intranet site in IIS)Will I be able to check for the session thats currenting set in the cookie?If the session is open then the user is able to see the Intranet and I assume I will need to do some checks for the app_role too.I am simply going to put the URL for the app in the menu for marketing and then do another check just incase someone gives the URL to someone who doesnt have access to the menu.Will i be able to check and use the cookie thats been instantiated by another application?
View 1 RepliesVS 2005 Using WithEvents With A Non-instantiated Class?
May 13, 2011Can you raise events from a class that has only shared members and doesn't get instantiated? I originally had the class members non-shared and created instances of the class where I need them. I had the events being raised and everything worked as expected. But as the class members are actually application level and do not need instancing, I converted all members in the class to shared so they could be accessed from anywhere in the program without creating an instance of the class. But WithEvents requires the creation of a class instance. I've done that and it seems to work fine when using an instance. And since I need the events handled in only one class, I can create the instance in that class and let all other areas access the class directly, without creating an instance.
View 10 Replies.net - Release A File Lock On A COM DLL That Has Been Instantiated Via `CreateObject`?
Dec 21, 2011I have a .Net 4 WinForms app that generates a DLL, calls CreateObject on the generated DLL then calls one of several methods that the DLL contains. The DLL is eventually used by a separate app. This WinForms app is just to generate and test the DLL hence why it can generate the DLL multiple times.The problem lies in the fact that calling CreateObject on the DLL locks the file to the process. The next time the DLL is generated it can't overwrite the previous DLL file on disk without closing the app completely and starting it again.
I've tried Marshal.ReleaseComObject, executing the CreateObject in a separate AppDomain, even setting the variable holding the COM object to a different COM object via CreateObject, manually calling GC.Collect() and a whole host of other things but none result in unlocking the file.The code flow is basically (simplified and generic names, etc.):
...
' Compile and generate DLL that is COM enabled and works fine
...
Dim foo As Object = CreateObject("Bar.Foo")
[code]....
is there a way to release a file lock on a COM DLL that has been instantiated via CreateObject without killing the process?
Note: this is a continuation of this original issue. I now have the DLL registering without locking the file but now the issue is with the CreateObject call not the DLL registration.

Getting Button Events From Multiple Manually Instantiated Controls
Aug 30, 2011I have created a simple custom control - we will call it a "panel with buttons". Here is how I instantiate it:
[Code]....
So what I wind up with are multiple instances of my panel. Each of these panels has a button on it called Button1.
My question is - how do I capture this button event in a way that I will know which panel index it came from?
In the custom control there is only the Button1_click event - and when I click on it in any of the multiple panels I manually instantiated the event does occur, but how I can tell which one of my instantiated buttons were clicked...
