twebbrowser

问题 I'm using Firmonkey (Rad Studio) for an IOS app. I'm using a TWebBrowser object but this seems to stay above all objects. I tried to right-click the TWebBrowser object and click Send to Back, but it did not. Does anyone know any solution? 回答1: Unfortunately, There are no solution for it. Because TWebBrowser is a native component, which is always on top of all controls.

问题 The TWebBrowser component has an error as described here [IE9] 'Floating point division by zero' occurs with WebBrowser. The solution is to call a procedure that will disable all division by zero exceptions. I am trying to fix this problem without having to call this procedure. So far, the best idea I had was to disable TWebBrowser scroll bars and try to simulate the same functionality using a TScrollBar . So far, it is working but that is the question: How can I synchronize the navigation in

问题 I am thinking about using the TWebBrowser component that comes within Delphi's default pallet of components in a project, but I wonder if it uses the IE version installed on the client machine? If yes: then I guess it would share its history, cookies, workoffline and stuff like that? Can I separate them somehow? Is there any webbrowser component that is free and is not shared with Internet Explorer on the client? 回答1: The current answer is not quite correct. It appears for compatibility

问题 I've currently implemented this demo code for an APP sucessfully, http://www.jasontpenny.com/blog/2010/03/23/custom-protocol-handler-in-delphi/, However it seems to only work if the application is a single form application. What I have found is that no Factory is returned for CoGetClassObject in: procedure NewProtocolHandler(const aProtocolName: String; aProtocolCallback: TProtocolCallback; aProtocollType: TGUID); var error : HRESULT; begin if _protocol <> '' then raise Exception.Create(

问题 I have a simple code: WebBrowser1.Navigate('www.foo.com'); But of course sometimes the browsing fails and the browser displays the error message. How can I catch when this happens? I want this so that I can make a some sort of a custom log. 回答1: I assume that the the OnNavigateError event handler is called when there is a problem. 来源： https://stackoverflow.com/questions/11568605/delphi-how-to-check-if-webbrowser-has-successfully-loaded-the-page

问题 I have an Delphi application that uses TWebbrowser component to automate navigation to another web application we have. My problem is that sometimes IE shows the infamous 'Are you sure you want to leave this page' message and when this happens, my app can't navigate to another pages unless an user clicks on 'Leave this page' button. I can't edit the website code to remove this warning, unfortunately. This message is plaguing my app for weeks, and I could not reach to a proper solution anymore

问题 I have a Delphi program that creates HTML files. Later when a button is pressed a TWebBrowser is created and a WebBrowser.Navigate causes the html page to display. Is there anyway to set the WebBrowser "default directory" so it will always be the location of the Delphi executable not the HTML file? I do not want to set the Base value in the HTML to a hardcoded value because then when the HTML is ran from another Delphi exe they are not found. for example: if the exe is run from D:\data\delphi

问题 How can i get text / html from a webpage on Firemonkey platform (Android/iOS).

问题 We are using a TCppWebBrowser Component in our program as a kind of chatwindow, but since the TCppwebrowser is using the IExplorerengine all links that are clicked is opening in IExplorer. One idea I have is to cancel the navigation in Onbeforenavigate2 an do a Shell.execute, but where hoping for a more elegant solution like a windowsmessage i could handle or an event or something. 回答1: Assuming that TCppWebBrowser is like TWebBrowser in Delphi, something like the code below should get you
