Hello, I am working on WinCE 5 with latest QFE patched, I found when
CE desktop is shown, send a VK_BACK key board event will cause the IE
launched. Is this a built in behavior of WinCE 5?
if yes, who defined this shortcut key? How can I remove it?

Thanks

I don't see how this could be true. Show us the code that you're using to
send the key. Maybe you're sending a character, not a key or something. If
what you are saying were true, it seems that pressing the Backspace key on
the keyboard would do the same; does it?

Dear Paul,
thanks for the reply, Just like you said, pressing Backspace key on
keyboard will also launch the IE.
(I am using a USB keyboard connected to my CE device)

Any idea what is happening?

Thanks

No, not really. I suppose that some application might have called
RegisterHotKey() and set up for that to happen, but I'd be surprised if it
didn't turn out to be unique to your device. You might register a low-level
keyboard hook using SetWindowsHookEx() and see what characters might be
coming in -- it's not documented for CE, but there are tons of references in
the newsgroup archives; search using GoogleGroups and look in just
microsoft.public.windowsce.*.

It's possible, I suppose, that your keyboard driver is mismapping the
backspace key to one of the hotkeys that do other things and it just happens
that your registry has that hot key set for IE.

If none of those things are revealing, you'll have to build a debug OS and
try to spot what's going on based on the debug messages and then trace back
to who is responsible. I don't suppose you're set up for a browser-based
shell or something...

Hi Paul,
I am also finding the same problem. In one of the Microsoft earlier
QFE mentioned that Backspace key closes IE.
Does this problem is a sideeffect to the same?

Karthik

I can't say. As I mentioned, I've been doing this for a while and I've
never (including right now with a CE5 box on my workbench), seen this.
Backspace, generally, in IE would go Back. Perhaps there was a bug in IE
that caused that to generate an exception and exit IE. Without knowing what
the bug was, there's no way to tell if it's the same situation. There's a
Windows CE chat tomorrow; you could attend and ask the actual Microsoft guys
if they know anything about it (I'd tell them, "When I hit the backspace key
on my <insert keyboard type here> on my Windows CE 5.0 device, while <insert
program name here> is running and the frontmost application, instead of
doing a backspace, IE is started. What gives?"

Hi Paul,
Thanks for your reply. As I have seen that Backspace and IE both
involved in the previous issue, So I felt that fix might have caused
regression. VK_BACK does launch IE on WinCE 4.2 , WM5 devices... only
on WinCE 5.0 devices it causes the same. I have a question is there
any shortcut key to launch IE in WinCE Device.

And I am soory to miss the chat session, If you have attended did you
have discussion on the issue?

Regards,
Karthik

There's no shortcut key unless you define one, as far as I know.

No, I'm not qualified to have any discussion on the topic, since I don't see
the problem. You could use one of your Platform Builder support incidents
to try to get direct support from MS.
