Hi,
I found how to set the HTMLViewer.UserAgent, but what I want is to get it.
Ideas ?

From what I can see, HTMLViewer has no UserAgent default value.
Otherwise, when it has been set, you get it by HTMLViewer.UserAgent as string

Hi Michel,
as far as I can see, Safari (last for 10.8.5) have one. It also can be modified (in the development menu).
BTW: the [HTMLViewer.UserAgent](http://documentation.xojo.com/index.php/HTMLViewer.UserAgent) page displays a used OS X
that is 10.5.8.
We all know that Xojo does not runs anymore below 10.7.
That was the Sunday joke.

I do not had internet while I was working with USerAgent, yesterday. Now, with Michel answer and SubWay Wifi, I get two entries in wikipedia:
[User-Agent (US)](http://en.wikipedia.org/wiki/User-Agent) and [User-Agent](http://fr.wikipedia.org/wiki/User-Agent) more complete because it gives now to get the user agent for a lot of development environments (VB6 for example).

Apparently, in Native mode, the HTMLViewer reports the same as the default browser.
I built a WE app and monitored the user agent the HTTPViewer sent : Mozilla/5.0 (Macintosh; Intel Mac OS X 10\_9\_3) AppleWebKit/537.75.14 (KHTML, like Gecko)
Now, it would make sense that the default property reported by HTMLViewer.UserAgent be the same. Instead, it is empty. Could be considered a bug, as the LR just says nothing about that incongruity.

HTMLViewer on Mac, Win or Linux? With(out) WebKit?

HTMLViewer.UserAgent is said by the LR to work only on Mac. And I checked on Mac.

What about WebKit on Windows? The built-in Xojo UserAgent only works on Mac OS X and is ignored in Windows.
