Is it possible to stop a Sub from executing its code when you, for example, click a button?
Example:
Private Sub ExecutedCode()
'doing things here
End Sub
Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click 'how to stop ExecutedCode() from being executed?End Sub
My problem is that some code I enter will not be executed. Here is an example of my Form Load event. If i debug the code then the first two lines are executed. The MsgBox won't be executed though. or anything else after it. My programm does run perfectly. But i cant make any changes anymore It's driving me nuts, I don't have the faintest Idea what could be wrong. I sent the code to a friend and he isn't having any problems at all. We both use win7 64bit (he has ultimate, i have home) [code]

I have a hashtable of a class that contains a timer. When this timer elapses x amount of time, it calls a subroutine within the class. This subroutine calls several other functions and subroutines and then its done until the timer elapses again. Now one of the subroutines updates a label on the form and i can see that happening when its supposed to. There is another subroutine that should be updating another label but it is not. I believe this would be a simple correction but when i set a debug point on the routine it does not work. I'm not going to post the code for this as it is hundreds of lines of code and its probably just a configuration in the IDE that got changed somehow.
I run break points around the rest of the project just fine, even in other classes that use timers. Does anyone else have this problem of code being executed but not being able to debug it?
I have a project with 2 forms. I need the code to be executed on one form first, which is why it is run first, then I want to hide it and just display the user interface form. I have the following code, it makes both forms appear, but I only want the user display form to show: [code] I call both these subs in the frmLoad of the Processing form.

The documentation for an API I am using explicitly says that I need to call close() on an object when I am done with it. I would also like to log something there.I understand GC, might not happen at expected time, etc. etc. I still want to implement some code at cleanup.I read that I need to Override Finalize() to do this.I wrote a console app to test and it looks like it indeed works.However, this does not work with windows forms. I put a break point and it never gets hit in the Finalize method.How do you add some code to be executed at cleanup time for a window form?Here is my console app test:
Public Class Foo
Public Sub New()

I have a backup script i made in VB. part of the code im having trouble with:
HTML
code:
Now this code is executed when a button is clicked, if the folder does exists, it displays a message and continues the backup. however if it does not it displays displays "does not exist box" then i want the application to close.
I played around with the application.exit commands but it seems like the code just skips over it, and continues to try and backup the data, then errors out. how do i make the application close, if the dir does not exist?
How do I wait until the report has finished rendering before the rest of the code gets executed?

I validate a DataGridView with the CellValidating-eventhandler.That works fine. However, I want to avoid validating when the user presses the Cancel button. In the sequence validation occurs before the event CancelButton.Clicked.
View 1 RepliesI have a form to register new users for my site and their are required field validators on the page.
I want to include a cancel button that redirects the form to the main page but unless the required field validatiors are satisfied it will not run the code when the cancel button is hit.
How can I have the code for the cancel button run even if the form is not fully filled out?
How can I avoid a first chance exception here. I need to use the cancel button to jump around the remove at code. The exception is caught and the bail out goto works, it is just the first chance I'd like to get rid of.

I would like to know if its possible to discard changes of only one record of only one table in datacontext. I use databind to bind my controls on a form. I modify one record at a time. after the modification, the user have to hit save button to validate. But he can hit cancel. I would like that the cancel button discard all the changes that the user has done. Is it possible?
View 3 RepliesI use pictureboxes on my GUI for click controls. The associated function will be executed whenever user clicks the picturebox control.
My question is that, how do I discard(not just suppress) a control click (message) for a period of time (i.e. during the function execution).
I simple just want the click messages made during the function execution discarded by VB.
I have searched everywhere, and have not found an answer. I would like to know how to enable your form to detect if a process is started. Something like this:

Okay so what I'm trying to do is get the filename from OpenFileDialog/SaveFileDialog, only without the full path, and dump said filename into a variable so I can use it for other things.
Using the Split function, I can get any part of the array between the delimiters (""), but what I'm trying to do is get all the information after the LAST delimiter in the string.
I know something like this exists, I juts don't know the right word to search about it, so basically I have a cosole application and if it runs twice it crashes. I wanna dispay a message: Sorry app alerady running.I can look at processes and see if my exe is there already running but that's much harder.
