99% of the trouble that you are having with your "application" is that you are using your event handlers to try and do things that you should not be doing. You are NOT going to click a button have some for loop in another button event handler stop running. You need to get a basic book on programming and work through it instead of asking this same "question" over and over.

There is an easiest way:

first define a bool field:

C#

private bool StopLoop = true;

then add this condition to your loop:

C#

for (int i = 0; i < 30; i++)
{
    if (!StopLoop)
        // Your actions
}

C#

private void Button_Click(object sender, EventArgs e)
{
    StopLoop = false;
}

My vote of 1: Philip's solution 1 is the correct analysis of the situation. The problem is that the loop itself is locking down the UI because they run on the same thread.

Solution 1

You have to move the copy loop to its own thread.
The easiest way to do that is using the backgroundworker.
There is an example here on the code project :
