I did a web browser facebook login form. I entered my password incorrectly or e-mail me
therefore form fails and closes form
How should I write a code to get off form?

for example
e-mail or password you entered is incorrect.
Please try again!

I want to be like . I do not want to close with an error of the form.

You could make/host an error HTML page and redirect (Navigate) to there when there's an error.

yup. but I don't know how to do

If it's a desktop application and you are embedding the web browser the html page can be in local folder. If it's hosted by you or online you need to add the page and navigate to the URL. If winform control use Navigate method; if hosted use JavaScript window.open or window.location.
