  On line 10, the exclamation mark is incorrect, it should be removed. We want to cancel the backgroundWorker when it is busy, otherwise there is no point to cancel something that does not run. Also, to avoid an error when pressing Start twice, we should put the condition if(!backgroundWorker1.IsBusy) { backgroundWorker1.RunWorkerAsync(2000); }

  I think something is wrong with the code you provided. If I click on Start button and the background worker starts and then I click on Stop, nothing happens. After the background worker completes operation, it will report its result, then another pop-up shows 0.

  Is there an exception handler missing in the code? By pressing the Stop button, the message "Invalid Operation Exception" appears showing the line "backgroundWorker1.CancelAsync()".

  Dear Mahesh Chand, I have read a few of your articles with fascination, thank you. I have a question regarding allowing the user to have multiple Forms ACTIVE simultaneously. I have read the ApplicationsContext and the Applications run which accomplishes this, however, I do not know whether it is possible to do this further down the hierarchy of calls. Let me explain, the initial form has calls to several other forms, in my case 12 (i.e. 12 menu options). One of the menu options shows a list of members with the member's basic details, just enough for the user to be able to select one, upon selection a more detailed form is presented to the user. So the user now can see both the members Form and the members detailed form. At this stage if the user finishes with the detailed form he/she has to close the members detailed form to gain access to the members form and then select a different member. What I would like to do is allow the user to be able to access both the members form and the members detailed form via the click of the mouse. So if the user after working on the members detailed form selects another member the details would be replaced automatically (programmatically) in the members detailed form. Can this be with ApplicationContext /Run or would multithreading be more appropriate for this type of application ? But that is not all ? what about all the other menu options ? Why can't they all be available as the user requires instead of forcing the closer of work (a form the user is working on) before selecting another task ?

    Dear Mahesh, It's still early days (I need to rework my project) but the MDI works a treat (perfectly). Thanks a million. I initially had issues where I was using the .Show() member. It wouldn't work when enclosed in a USING statement. So I've removed the USING statement and it now works fine. Passing of data between forms is via reference so should not be difficult to have an event check for changes and update individual forms respectively. Once more, thanks again.

    Thank you. I think your work just need a WinForms MDI application. MDI allows multiple Windows to be opened and available all the time. Forms data communication can be done via delegates and events. See here: https://www.c-sharpcorner.com/UploadFile/84c85b/building-mdi-winforms-application-using-C-Sharp/

  I have read most of the your article since my college day, I observed your code is always complex to understand even in the simple logic.

  Good example, Thread.Sleep(20000) is huge, interaction of application is very less.

  I think it would help to explain the realtionship of the arguments parameeter of the RunWorkerAsync Method and the Argument member of the DoWorkEventArgs Class.
