I am writing a BHO for customizing IE7. For zooming facility, since I couldn't find any Zoom API I am trying to achieve this with IHTMLStyle3::Zoom. To get the pointer to IHTMLStyle3 interface I called IHTMLElement::get_style method but the problem is that "get_style" method returns pointer to IHTMLStyle interface whereas I need IHTMLStyle3 interface pointer because this has the "Zoom" method. Can any one suggest me a solution ? or any other better approach for zooming? any ideas/snippets on this will be helpful Other details: Language: C++, visual studio 2005 IE : IE7

@Anthony Yes I tried queryinterface earlier but it didn't work.Now its working :). Actually earlier I was using IID_IHTMLSTYLE3 instead of IID_IHTMLStyle3 . But the bad news is I am still unable to zoom my IE :( Anyway thanks for your help. @Igor Yes I have tried OLECMDID_OPTICAL_ZOOM, OLECMDID_OPTICAL_GETZOOMRANGE but I am getting a compilation error " OLECMDID_OPTICAL_ZOOM : undeclared identifier". I couldn't find which header file to include for this. Thanks, Yogesh.

You need to download and install the latest Platform SDK. Or define your own constants: OLECMDID_OPTICAL_ZOOM has a numeric value 63, OLECMDID_OPTICAL_GETZOOMRANGE is 64. -- With best wishes, Igor Tandetnik With sufficient thrust, pigs fly just fine.
