hi

i am hosting a webbrowser control in an vb app. if a page contains
javascript window.open position my webbrowser control resizes and moves.
How can i avoid this behaviour? IE6 Events like setwindowleft etc just
don't fire!

i already tried
- subclass the "Internet Explorer_Server" to get WM_poschanging
messages but none ever appeared
- setwindowleft etc events (webbrowser1.move 1,1 -> no effect)
- DOM : in NavigateComplete2() hook the
webbrowser.document.parentWindow.onresize event -> no effect

having no clue

I think accidentally your control has a name that is mentioned in
window.open as a target, so your control becomes target of a navigation.
Or IE is set to reuse browser windows, and your control just happens to
be the one chosen for reuse.

To avoid any such problems, set RegisterAsBrowser property to false.

thanks for your reply Igor,

the target for the new popup is on form2.webbrowser1, and i want to show
form2 with custom titlebar / no navbar / no rightclick etc. and no standard
webbrowser window.

my code is on form 1:

Private Sub WebBrowser1_NewWindow2(ppDisp As Object, Cancel As Boolean)
Dim popF As Form2 'contains a webbrowser control
Set popF = New Form2

popF.WebBrowser1.RegisterAsBrowser = True
Set ppDisp = popF.WebBrowser1.Object
popF.Visible = True
end sub

so on form2 i have

Private Sub WebBrowser1_WindowSetLeft(ByVal left As Long)
WebBrowser1.Move 1, 1
End Sub

which never fires when the popup contains someting like
<BODY onLoad="if (window.screen) { window.moveTo(5,
screen.availHeight/4);} ">

(check http://www.techno.de for this popup )

so when the window.moveTo method is called i need to get any event to deal
with.

I found only one way to handle moveTo, resizeTo and such. I subclass
browser window as obtained with IOleWindow::GetWindow call, and
intercept WM_WINDOWPOSCHANGING window message. The handler cancels
repositioning of the control, and instead uses the supplied coordinates
to reposition parent window (the form in VB parlance).

Unfortunately, I have not found a way to handle both moveTo and moveBy.
moveTo causes WM_WINDOWPOSCHANGING to be sent with new position
expressed in screen coordinates, and moveBy in client coordinates, and
no indication as to the cause of the move. So I assume that the
coordinates are screen, and document that moveBy behaves erratically and
is not supported.

Before you ask, I have no idea how to subclass a window in VB. I'm a C++
programmer.
