I wish to create a browser on a tabbed page at runtime, depending on the 
configuration of the system. I am worried that the IDE uses the ControlData 
property for something when it is not dynamically created, this data appears 
in the DFM file.

Should I be doing something to set this property when I create it 
dynamically and how is the property set, is it passed the address of a 
structure or array containing the bit pattern.

I examined the ControlData structure in olectnrs.hpp but the pattern in the 
DFM file does not seem to correspond in size.

TIA
Joyce

Do you mean an instance of TCppWebBrowser on a TTabSheet of a TPageContol ?

That leaves me puzzled.

Don't understand that. As far as I know you don't have to bother with
ControlData. Just create the CppWebBrowser. If you tried already, what
where the actual problems ?

On trying to create the control without using the ControlData, I do not 
think the Control is shown, the background is the TTabSheet color and not 
the white when created at designtime. The control must be created as it 
accesses the internet, but is not shown.

No. Please show your code. Don't forget to set the parent.

This works for me:

void __fastcall TForm1::Button1Click(TObject *Sender)
{
   TCppWebBrowser *CppWebBrowser = new TCppWebBrowser ( this );

   CppWebBrowser->TOleControl::Parent = TabSheet2;
   CppWebBrowser->Align = alClient;

   CppWebBrowser->Navigate ( WideString (
	"http://kb.lv.ukrtel.net/foto/albums/userpics/10005/12526_2.jpg"
	) );

   /*
   CppWebBrowser->Navigate ( WideString (
	"http://kb.lv.ukrtel.net/foto/displayimage.php?album=41&pos=0"
	) );
   */
}


Don't take to much luggage ...

I did try to set the Patent for CppWebBrowser but of course this did not 
exist.

By using CppWebBrowser->TOleControl::Parent everything now works.

Many Thanks,
Joyce

I wouldn't worry about setting ControlData.  I think it stores 
information if you drag@drop content into the TCppWebBrowswer control 
during design time.  I accidentally dragged a URL link from an open IE 
window into a TCppWebBrowser control of a Form I was creating and the 
resulting web page kept appearing in the TCppWebBrowser control during 
both design/run-time.
