Using the webbrowser control is there a way to load a url then prevent the user from navigating to any links other than ones in a list of approved urls ?

Which events should I be looking at to code

I looked at scripting in 'addresschange' and 'navigationstart' events

in addresschange event i found i could evaluate the uri variable in addresschange and using wb_1.StopNavigation()

is this the right approach?

Frank.

Hi Frank;

  The 2022 R3 release introduced the WebView2 engine "under the hood" to drive the built-in Web Browser control as the new standard.

AFAIK, there is no way to prevent this from happening. I think that this would be an enhancement request.

Regards .. Chris

For a question such as this, I believe it would be helpful for us to know which version, release and build of PowerBuilder you are using and which browser (chromium or webview2) are you using.

Best regards, John

Appeon changed the underlying web browser "engine" used by the PowerBuilder web browser control beginning in PB 2022 R2. Because of this recent change, it was important to know the version, release and build of PB that you are using. We have no way of knowing what version of PB you are using, so regardless of the particulars of the question it is ALWAYS a good idea to mention the version, release and build in your question.

I see from your separate response that you are running PB 2022 R3. The solution you have proposed sounds reasonable, but I'm unable to judge whether this is the only or best approach. Have you tried it? If not, please do so, and update this thread with the results. Perhaps others in the Community will offer their insight and experience, but I would not wait in the hopes of hearing from them. Good luck!
