Hi

With PowerBuilder 2019 R2, can we transform the new web browser control into an HTML editor (like Internet Explorer?)

Regards

Thierry

Currently not. Some APIs not there in this "release 1" of PowerBuilder's native WebBrowser control.

I researched this recently - Chromium definitely has a DesignMode. You can even turn it on using the Console in Developer Tools (I tested it). However, I have no idea what its behaviour is like compared to the MS WebBrowser control's DesignMode, which we use for our HTML editor for mail-merge documents in our application, which works quite well.

Hi Armeen,

I did a similar request already on 24th of Jan last year: https://www.appeon.com/standardsupport/track/view?id=2205

I think the big issue for those of us distributing software via downloads is the installed size needed for a Chromium-based browser. The commercial ActiveX version that is available, WebKitX, says its redistributable is 75MB. (And our whole app's download is currently only about 30MB!) Whereas using the MS WebBrowser control needs no redistributable, because it is always included in Windows.

Yes I think we probably do, Armeen, or at least on quite slow Internet. And we have a lot of customers who choose not to have Internet access at all on their church computers (presumably because they are worried about malware) so they have to download elsewhere, copy to a USB, and bring that to the church to install. We want installs for our customers (many of home are not at all expert with computers) to be fast, easy, and painless, and the bigger the install, the less that is true.

And more to the point, our solution with the MS WebBrowser control for mail-merge editing and merging is working well. There would have to be a huge "win" in switching to a Chromium-based browser control for us to be willing to more than triple the size of our installers for that one feature.

I see. Well the old MS WebBrowser control is still in the product and we do not plan to remove it in the foreseeable future.

Armeen, are we talking about the same thing? I'm taking about including the WebBrowser as an ActiveX control on a window, as in Roland Smith's good free example. That isn't part of the product, it's part of Windows.

As follow up to this and several other browser related Q&A discussions in recent weeks. Today I rechecked Microsoft docs for WebView2 - the upcoming Chromium-based Edge browser component:

  1. As of 15-Jan-2020 (latest release notes) this component is still Developer Preview.

  2. This component is not plug-and-play replacement for the existing IE-Chakra based WebBrowser control.

    1. WebBrowser control is wrapped as ActiveX (or whatever the name is these days) and therefore accessible as OLECustomControl in PowerBuilder.

    2. The new component has no such OLE-accessible wrapper. You can add it to a C++ win32 app but you need to install a WebView2 SDK before you can develop software to interact with it.

TO-DO LIST BEFORE AVAILABLE

First, the WebView2 component needs to become generally available

Second, someone (Microsoft or someone else) needs to wrap it for OLE-access before we can use it in PowerBuilder user interfaces.

Sounds like a good candidate for a visual PBNI extension.

Does Chromium even support a Design Mode?

Good question. Honestly, I haven't looked.

Some HTML will currently not render either in my testing.

Especially more advanced HTML like HTML5 (depending on the feature used)
