And based on your html page, I tried to test by using WebBrowser control. I suggest you could set "window. Please check the following:. If so, can you please suggest me a good JavaScript course. What you should do is stop using the Webbroswer crutch thing from a Windows form, and learn how to do real Web development. So basically give me a list of Programming languages that do real Web Dev. It is often used when uploading a file or submitting a completed web form.
Okay, let get this clear. I can't tell you anything about the Webbroswer control. I have never used it and never ever plan to either. I realized that it was giving me errors saying that Runtime errors might occur when converting ' System.
HtmlDocument' to ' mshtml. You mean you are unable to figure out why the code quit working after you altered the code? Why don't you alter it back to what it was before you altered it. Then alter a single line that you altered to cause it to quit working till it quits working again. Then you will know what line that you altered that the code quit working at. Well considering Neda Zhangs code is still in this thread I don't see how you can't alter it back.
After all you said all you did was alter it to have System. And then you said the code quit working. In the future if you really don't know what caused the code to quit working then don't say what you did caused it to quit working.
WebBrowser is not really efficient to do that job as it relies on IE that is a wreck like many other in this Forum keep saying and that's true.
Anyway, I'm gonna finish that version that uses webBrowser control and start a new one with HttpClient or Net. So which one should I use??? So confused!!! Clearing cache where you have have made changes to the HTML or to JavaScript code where you don't have to restart the browser session is ctrl-ley and Refresh F5 or Refresh Icon on browser's address line. What you are talking about has no affect on any browser session currently running that you are doing some kind of development work and running the browser solution.
No not really, the wreck is the Webbrowser control crutch and using it from a desktop solution. That's the tragedy in its own rights. I am glad your issue has been resolved, I would suggest you mark the solution as answer, and then others could find the solution easily. For new issues, I would suggest you post a new thread, and then we could focus on new issues.

However on IE 8 on Windows 7, it always shows the onBeforeUnload notification, specifically if there are no unsaved changes, it would just say "null".
How can I prevent IE from showing onBeforeUnload notification when user has saved everything and wants to navigate away? Remove the return null line and it should be fine in Javascript null and undefined are different things.

Why dont you use another event handler called onbeforeunload instead. It should work. Onbeforeunload will execute first before the window closes, so that should solve your problem.
This is handy if, for instance you're working with SharedWorkers and you need to tell the worker that there is one less port to manage -- otherwise, you could end up refreshing one browser tab and get something like a "Successfully connected with: 10 other tabs" because the one tab is keeping the worker alive while the other tab's refreshes keep pushing new port connections to you array.
