implement these things, but these things are unclear in just a few words, so after a long delay, I am sorry again. I plan to write it out so that anyone who needs to learn can get reference materials;Let's first analyze the general implementation ideas. First, we need to understand that to capture the data on the page, we actually need to take the HTML code for analysis and then read the data in it, A friend who has worked on the winform program may easily understand that there is a

in general, when the ReadyState property becomes Readystate_complete, the WebBrowser control instructs the Web page to load by triggering the DocumentCompleted event. However, when the loaded Web page contains a frame, the event may be triggered more than once, so it is not easy to judge that the page is loaded.From the official website of Microsoft, not every frame corresponds to a documentcompleted event, and only the frame that triggered the Downlo

When IE browser encountered a script error, in the bottom left corner of the browser will appear a yellow icon, click to view the details of the script error, there will be no pop-up error message box.
