I have to set a property in an OCX object and this property is not avaiable from the properties menu in the resource file. The OCX exchange data with an object, m_addx, whose class is derived from CWnd via DDX_DODATAEXCHANGE(), so I thought I could use m_addx.SetProperty(), but It wasn't useful because I have to pass a LPCTSTR string to the method in order to set the property itself.
So I tried with:
InvokeHelper( propID, wFlags, vRet,pvRet, VT_BSTR, ...) where ... is the LPCTSTR string I have to pass to the method and that can assume one of two values ( I wonder something like "Unit" or "System"); the problem is that I don't know these values and I can't retrive them from any file because I was given the OCX like an unknown object, attacched to a CDialog object in the resource file, without source files .
Is there a way to retrive these informations (i.e. the two strings I have to pass) knowing only the ID of the Property? (Maybe with a COleControl object?)
