ActiveX ClassID

Hi

we are using CVI 2012 and we want to register a Microsoft Internet Webbrowser by activeX. We want to use the following Cmd

int NewActiveXCtrl (int Panel_Handle, char Control_Label[], int Control_Top, int Control_Left, const GUID *Class_ID, const IID *Interface_ID, char License[], HRESULT *ActiveX_Error);

but we do not know what the GUID and ClassID is.

How can we create an ActiveX Microsoft Internet Webbrowser in a Panel?

Can anybody help us?

thanks in advance

Oliver
