When IE browser encounters a script error, a yellow icon appears in the lower left corner of the browser, click to view the details of the script error, and there will be no pop-up error message box. We are writing in the WebBrowser program to open the Web page, encountered a script problem is, will pop up an error box, need to be confirmed before the execution. If the program we are designing is used to automate the processing of Web pages, then when
it. My colleague was very calm along the way, in the back to the daughter-in-law called, silently waiting for the arrival of late. Alas, in the future must be in the bell rang on the wake up, because perhaps will encounter delays in the event, to set aside the time to solve the problem.Well, it's not bothering me now. The first article can not just grumble, write something useful. I've been working on WinForm and Android for a while, and I'm going to make sure that my skills are improved before

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
AProgramThe main interface of the program is designed on a webpage. The effect is very good. html + CSS can be used to achieve richer interface effects, which is easier than using Delphi directly.
The implementation method is very simple. Add a webbrowser component in the form, and then execute the followingCode:
Webbrowser1.navigate ('d: \ soft \ homepage.html ');
However, a problem arises: The webbrowser
Due to project requirements, I recently studied the use of webbrowser components and mshtml in Delphi, sorted out the results of this study, and wrote them down for your convenience, 2. It can also deepen my memory. hope to help you ..., At the same time, if you have a better solution or problems that I have not mentioned, please let me know. Let's make progress together ..., some of them are information I collected from the Internet. Thank you guys..

You are executing a method of twebbrowser to perform the expected operation, for example, execwb may encounter errors such as "trying to activate unregistered lost targets" or "OLE object not registered", or no errors but no expected results, for example, you cannot copy the selected webpage content to the clipboard. When I used it for programming, I found that execwb sometimes works but sometimes does not work. I added twebbrowser to the default Project Main Wind
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
