The device vendor has chosen Opera Mobile as the browser and implemented the
WebBrowser control interface (see my other message), in terms of Opera, not
Internet Explorer Mobile. As a result, different things happen when you do
operations. As you see, Opera opens, presumably because it runs only as a
separate application, not as an embeddable control. The device vendor may
have provided some way to switch the default browser, which might work for
you, if you can live with changing a global setting on the device...

Webbrowser, DocumentText and local image
Hi,

I have new problem with WebBrowser :)
I generate html document at runtime and display it in webbrowser using
code:
WebBrowser webbrowser;
String myHtmlDoc;
webbrowser = new WebBrowser();
myHtmlDoc = @"<html>message to display <img='\temp\image.png' \></
html>";
webbrowser.DocumentText = myHtmlDoc;

the result is:
I see text 'message to display' but instead of image I see 'red X' -
you know, the image which is shown when browser cannot find the image
to display.
Ofcourse path \temp\image.png is valid, this file exists.
If I create a document on the device with mentioned content and load
it to webbrowser (using Navigate()) than image is displayed.
If I use image from network:
myHtmlDoc = @"<html>message to display <img='http://server/image.png'
\></html>";
than the image is displayed.
Seems that in DocumentText cannot contain reference to image on the
device. Does anybody know how to solve that problem?

Wouldn't that need to be "file://temp/image.png" or something like that? The
problem is likely to be that the WebBrowser does not know what the root path
from which the HTML was loaded is, so it cannot interpret \temp\image.png.
That is \ related to where? What server? There might be some way to tell
the WebBrowser object that information before you set up the document text, I
suppose...

I guess that, if you have checked everything that could work for the case of
setting the document text explicitly, maybe you should look at other methods
of getting the browser object to load your generated page (generate it to
disk and point the browser to it, etc.)

Another question - does WebBrowser support javascript? If yes, than is
any event called when <img /> element got focus?
I have checked with onfocus and onactivate - does not work.
I use smartphone so focus in html page is changed by cursors. I'd like
to change source image when <img /> is selected.

Yeah, I have solved that problem by writing html on the device and load
it from local storage. Hope that client'll accept creating temporary

But if anybody solve that problem another way, I'd be greatful

Something strange.. this solution works fine on emulator.
On SPV e650 browser does not show page loaded from local storage.
Display is empty. I load:
browser.Navigate(new Uri("\\temp\\page.html"))
path is valid because if I use incorrect filename than webbrowser
shows error 'not found'
If I load page from internet - that is ok.

The browser is permanently linked to the OS version. If you have Windows
Mobile 5, you can never add to that the browser from Windows Mobile 6.1, say.

The WebBrowser control in .NET CF is just a thin wrapper around the actual
WebBrowser control used in Internet Explorer Mobile on the device. It has no
significant functionality of its own. There should be at least some
JavaScript support in the WM6.1 version of the browser. You may be able to
find a list of supported script statements online...
