TWebBrowser - trap invalid URL

[AP81]

Hi,

Using a TWebBrowser control, it is possible to trap if a URL is invalid? It doesn't look as though a TWebBrowser component has this capability.

For example:

WebBrowser1.Navigate('[URL unfurl="true"]http://asdfasdfsadf');[/URL] //I need to trap that this failed.

Thanks.

I think I have code at home that addressed this. I'll look. In the meantime, have a look at OnNavigateComplete2 event (TWebBrowser) and the accompanying example in Help. Getting deep, but also look at GetStatusCode method (TWebResponse).

In procedure Navigate2(var URL: OleVariant; var Flags: OleVariant); overload;
You can assign "navAllowAutosearch" to Flags:

navAllowAutosearch (16) If the navigation fails, the Web browser attempts to navigate common root domains (.com, .edu, and so on). If this still fails, the URL is passed to a search engine.

There's no place like LocalHost? Just kidding, good one!

Thanks Roo,

using idHTTP I found that I can call idHTTP.GET and dump the URL into a file stream. If that fails,then I know whether it is a valid URL.

Kind of round-about, but if it works, what the heck!
