Exit is suggested, and even:. On the other hand, the accepted answer on the second link says " you should never have to call Application.

Exit in a properly-designed application ", contradicting the above and an answer further down which says Application. Exit calls Close on all forms in later versions of. Otherwise, when does Application. Exit fail to work except when I write code which cancels it? A comment in my recent question assures me that calling Socket. Close isn't even necessary, but now I realise that this may not be completely true since I was using End to terminate before. It's a perfectly acceptable way of closing an application and will cause all forms to attempt to shutdown.

Individual forms can override this behaviour, for instance if they have unsaved work. This will leave your application running afterward so you need to decide if that needs to be handled. Saying that I only use it if an external actor needs to shutdown my application. Otherwise I leave the app to exit when its main form closes. You also need to consider the state of any foreground threads you have as these can allow all your forms to close but leave the thread processing in the background.

End is a very brute force technique and should be used as a last resot. A well designed application should be able to shutdown by closing the forms or by calling application. I have used the approach in the past of launching a timer which will call End just before I call Application. Note : Application. Exit doesn't block. So Application. Exit : End might as well be End which is not ideal. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Exit does not define the end of a statement. In the following example, the loop condition stops the loop when the index variable is greater than The If statement in the loop, however, causes the Exit Do statement to stop the loop when the index variable is greater than The following example assigns the return value to the function name myFunction , and then uses Exit Function to return from the function:.

The following example uses the Return Statement to assign the return value and exit the function:. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info. Contents Exit focus mode. Is this page helpful? Please rate your experience Yes No.

If you observe the above code, we used Exit statement to terminate the for loop whenever the variable i value equals to 3. If you observe the above result, whenever the variable i value equals to 3 , automatically the for loop execution has stopped.

This is how we can use the Exit statement in for loop to terminate the execution of for loop based on our requirements. In visual basic, we can exit or terminate the execution of while loop immediately by using Exit keyword. Following is the example of using Exit keyword in a while loop to terminate the execution of loop in a visual basic programming language. I am not able to get the exit window button to terminate once I click on it.

I am not sure what I am doing wrong. This is the code I am using for it: btnExitWindow. Everything else is working fine when I run the program. I would like to terminate a do until Actually my problem is to stop a loop when i click on stop button. However, the code continues merrily along its way until I get a 'null reference' error which I'm trying to avoid via Force Termination. My problem is that Application.

Exit doesn't work, and the program just continues along as normal. Now I have a sub to validate a bunch of textboxes and combo boxes. I previously used many IF statements to validate and pop up different messageboxes and Exit Sub in every IF statement. But I heard that too many Exits will decrease the efficiency and they were not recommended to use. Instead, nested IF is better because it will let the process naturally go to the end.

Then I found out that if I use nested IF,it will be hard to read, since messageboxes are all separated from conditions. How do I exit from the recursive loop from the code below. I would like to notify the end-user to select a checkbox in a msgBox before I exit the loop. I have a basic three form application. It doesn't seem to close after navigating through forms. If I were to open the application, and the main form is displayed.

If I press the X button, the application closes fine Goes from processes If I were to open the application, and then navigate from the main form to another form using me. I have this program and I want to put either a Quit button or Exit Button to quit the program besides using the 'x' at the upper right corner. When a user clicks on the little red "x" a. I want to be able to show a messagebox that asks if the user wants to exit the form or not.

Obviously if they click no, I want the form to stay open, how would I do this? I have recently implemented to following code on a good deal of my forms. However, when the user closes the program I now get an Application Crash screen. My application exits sometime without any exception. I am using loop in separate thread to read HID device.
