Hi,

I came over a portion of code like this (Delphi):
(FIE is a TWebBrowser - Embedded IE Control)

FIE.Navigate(Filename);
while (FIE.ReadyState <> ReadyState_Complete) do
   Application.ProcessMessages;

This does nothing else than loading a file/url into the Browser. So far
so good - it works if the MSHTML Window is visible. If the MSHTML Window
is NOT visible it remains in this state: ReadyState_Interactive
(According to MSDN this means: Object is interactive, but not all of its
data is available.) Why is MSHTML not proceeding? My app is ending in an
endless loop because of this :-/

TIA,

Hi Thomas

I suspect that this is 'by design'. The WebBrowser control is designed for
rendering html pages. If the control is not visible then the content is not
rendered, and if it is not rendered then the data is not available.

Hi!

That renders MSHTML to be useless to me :-/ I can live with the fact
that it is inactive but this also means that the Document Object has no
body elemtn (FDocument.body is nil) - so I can´t modify/load any HTML
into the control :-/

Any idea how to mimic the behavior of DHTML beside some dirty "OnShow"
event hacks?

Do you require the rendering features? If that is the case, and you will
never want to show the page, you don't need the full WebBrowser control.
Instead, just use mshtml. Note that the WebBrowser wraps mshtml and shdocvw.
The latter provides the rendering services whilst the former maintains the
DOM.

You can create and manipulate a page in memory using just mshtml. You will
need the IPersistStreamInit interface exposed by the document object.

Navigate to about:blank on a new HTMLDocument object and wait for complete.
Call InitNew on the IPersistStreamInit interface.
Call Load to load a string.
Wait for complete.

If you need to view the page can you not allow the control to be visible?

Hi!

More or less: yes.
Not really immediatly, but after I loaded/modified the HTML code it
should be displayed/editable.

Idea:

I create an IHTMLDocument2 object - fill and modify it. How can I now
attach the object to the Webbrowser object?
Maybe someone can provide me sample code? :)

I can - but in the same procedure I want load the HTML string into the
control.... so it might not matter if its visible or not :-/

Best regards,

I use the WebBrowser control in this way with no problems.  I use dirty
old Visual Basic, and my WebBrowser control is hidden and I wait until
it's finished loaded and then access the HTMLDocument interface.  Here
is the code I use:

     If ie.Offline = True Then
         pageTimer.Duration = 10000
     Else: pageTimer.Duration = 60000
     End If

     pageTimer.Enabled = True
     ie.Visible = False
     ie.Navigate strLocation

     Do While ie.ReadyState <> READYSTATE_COMPLETE
         DoEvents
         If pageTimer.TimeRemaining = 0 Then
             ie.Stop
             Exit Do
         End If
     Loop

     pageTimer.Enabled = False

     DoEvents
     Set thisIE = ie.Document
     DoEvents
     Set thisIEWindow = thisIE.parentWindow
     DoEvents

'ie' is the webBrowser and 'thisIE' is an HTMLDocument variable.
thisIEWindow is an HTMLWindow variable.
I have included a timer to abort the load if it seems to be in an
infinite loop.

This is quite basic but works well.
