How to implement clicking URL "my://showAdialog" just showing a dialog without changing the current page content?

[nbuyer]

Hi,

I wish to implement clicking a custom URL (e.g. my://showmsg/abc) inside my page to call my Windows App to display a dialog box with "abc" information, and I want the page to remain unchanged after closing the dialog box.

Currently, I'm using js via ExtensionHandler.Execute() to do that, but can ICefResourceHandler be implemented directly to achieve a similar effect? Right now I only know how to use TCustomResourceHandler to return something like a jpg that returns a stream and can't return a “no data” response.


Thanks for your help.

Hi,

Try using TChromiumCore.OnBeforeBrowse to cancel the navigation with that URL and then send a Windows message to the form to show the dialog asynchronously.

That's a good idea, though not very elegant. :-p
I will try. Thanks.
