consulting- How to Access iWebBrowser2 property ScriptErrorsSuppressed from C++

IWebBrowser2 *nav; nav->ScriptErrorsSuppressed = true; yields error C2039: 'ScriptErrorsSuppressed' : is not a member of 'IWebBrowser2' C:\Program Files\Microsoft SDKs\Windows\v7.1\\include\exdisp.h(1310) : see declaration of 'IWebBrowser2' Microsoft .NET documentation says iWebBrowser , including properties, is available from C++, and that Visual Studio is the development environment to build .NET applications. ========================================= The project is simply to tell me how to set the property ScriptErrorsSuppressed(a flag to suppress Script error pop-up dialogs), or achieve the same effect. If you know how, this is a really short project. IF YOU DO NOT ALREADY KNOW HOW DON'T BID. I am not expecting code, but it may be simplest to send a short code fragment, showing an [login to view URL] which compiles. I have latest Microsoft sdk (according to download page) It says 7.1 This feature is documented as available since .Net 2.x, but NONE of the documented properties compile, as they are missing from MS 7.1 SDK header files. I will accept multiple bids, up to $50, and pay for all working solutions. ====== below is copy of post to microsoft .net forum, which explains problem========== According to [login to view URL] Every WebBrowser and IWebBrowser2 has a public property, which in C++ looks like public: property bool ScriptErrorsSuppressed { bool get (); void set (bool value); } ============================================== According to [login to view URL] .NET Framework .NET Framework Highlights Download Visual Studio 2012 Install and try Visual Studio 2012 today.<<<<<< .NET Framework 4.5 Download the NET Framework 4.5 today.<<<<<< The way to develop a .NET 4.5 is to use Visua Studio and the Downloaded .NET. Oddly, the .Net download listed below Visual Studio appears to have no developer SDK at all (so is useless to Visual Studio). In any case, I installed this .NET update. ===================================== This page says it has the .NET SDK for Visual Studio, 2005, 2008 and 2010 [login to view URL] After install, I have an SDK version 7.x, newer than the version 6.x that came with my Visual Studio 2008, and according to this page, the "latest" SDK but nav->ScriptErrorsSuppressed = true; gives error error C2039: 'ScriptErrorsSuppressed' : is not a member of 'IWebBrowser2' C:\Program Files\Microsoft SDKs\Windows\v7.1\\include\exdisp.h(1310) : see declaration of 'IWebBrowser2' And SDK 7.x exDisp.h does indeed have a declaration of iWebBrowser2, and it and its parent classes iWebBrrowser and WebBrowser also do not have it, nor do they have the bulk of the properties listed in the documentation at top of this post. A search of the SDK shows no other definitions for iWebBrowser2 except this one in v7.1\include\exdisp.h. So, is the documentation really that broken that it has dozens of properties and methods never implemented, Or is the page that says its the SDK for .NET wrong, Or am I just missing something really basic here?
