Question

I have the following code, Some times ArchiveFiles() take more time to complete its execution.

When user clicks exit option more than one time from context menu, Application becomes non responding if ArchiveFiles() takes more time. How can I show a wait message when he clicks the exit option again?

private void exitToolStripMenuItem_Click(object sender, EventArgs e)
{
    ArchiveFiles(); 
    Application.Exit();
}

Thanks

You can use BackgroundWorker.

Using BackgroundWorker, you will be able to execute time consuming tasks such as the one you have on another thread so that the UI doesn’t freeze. You will be able to report the progress of that task, then report it accomplishement and executing what ever logic you need after its completion.

Handle the BackgroundWorker.DoWork event to start the operation that performs the potentially time-consuming work.

Handle BackgroundWorker.ProgressChanged event to report the progress of an asynchronous operation to the user.

Finaly, handle BackgroundWorker.RunWorkerCompleted event to implement whatever logic you want to be implemented after the task has been completed.
