I made a httpwebrequest in a sub. The form on my program has a start button which calls the sub. I want to add a Stop button to it to stop the httwebrequest if the user so chooses.
How would I do this?

2Since you've tagged this with `C#`, I assume by "sub" you actually mean "function" or "method"? C# does not use any of those keywords, unlike VB.NET, which uses `sub` and `function`, but they are generally all called `functions` or `methods` in C# – Andrew Barber Feb 05 '12 at 16:20

Call Abort on the HttpWebRequest.
BEWARE that this might cause some strange behaviour... for example: depending on how you made the request and in what state it is this might lead to a deadlock.

How would I call it? Using an if statement saying if the button was clicked to abort? – user1017524 Feb 05 '12 at 16:20

@user1017524 to answer that you need to show your source code... otherwise I would just speculate... – Yahia Feb 05 '12 at 16:22

How would I set up an if statement inside my sub to check if the button was clicked? – user1017524 Feb 05 '12 at 16:29

@user1017524 I don't understand... you say you are using C# - in C# there is nothing called sub. you are talking about some `if`statement - why don't you use an event handler ? – Yahia Feb 05 '12 at 16:34

Nevermind I figured it out. I created an int, made it equal to 0. Then when the stop button is clicked the int = 1. So in my request I set up an if statement saying if the value of the int is greater than 0 to abort. Then I make the value of the int = to 0 again :) – user1017524 Feb 05 '12 at 16:37
