WebBrowser control
-
I am using WebBrowser control in VC++ project. WebBrowser loads page form Intranet Server. I don't want to show message like "The page cannot be displayed" in case server is down. I want to show some local html page which will be stored on client computer. Does anyone know how to catch event when page is not successfully loaded from server? Thanks Sanjeev.
You could trap the NavigateComplete event and check the url. If it is not what you where looking for, redirect to the local page.

Like Mark said but I'd use the DocumentComplete Event in case frames are being used instead. I actually like to verify with the changing Title text as well, for more specific errors. Regardz Colin J Davies

The page cannot be displayed message is a resource in IE, so you can't change it directly. I'm not sure DownloadComplete or DocumentComplete would be fired until after the error page is loaded. You may have to send an http request to the server first to see if it returns an error, then show your page. Like it or not, I'm right.

From MSDN: DocumentComplete event when the document has completely loaded and the READYSTATE property has changed to READYSTATE_COMPLETE. NavigateComplete2 The document might still be downloading (and in the case of HTML, images might still be downloading), but at least part of the document has been received from the server, and the viewer for the document has been created. The latter method would allow you to determine if the correct page were loaded(or loading) without having to wait for the READY_STATE to be set. You'll also note from the documentation that NavigateComplete2 is used for frames also.

In my opinion that would be a very poor technique. Depending on the server configuration, error messages can be changed so it is possible from that end to change the 404 error page.

NavigateComplete2 method is called after the document is loaded (and displayed). I don't want the "error page" to be displayed at all.

Read the above reply when the NavigateComplete event is recieved the page can still be downloading elements.
