// Purpose: C++ wrapper for PROPVARIANT
|
|
//
|
|
// History: 01-Aug-94 KyleP Created
|
|
//
|
|
// Notes: A couple of variant arms are not implemented below.
|
|
// VT_BSTR because its type signature is identical to that of
|
|
// VT_LPSTR. VT_SAFEARRAY because I don't fully understand the
|
|
// structure.
|
|
//
|
|
// Some types are duplicate base types with a different variant
|
|
// tag. These include:
|
|
// VARIANT_BOOL (short)
|
|
// SCODE (long)
|
|
// DATE (double)
|
|
// We cannot create trivial constructors for the above because
|
|
// of the type collision. You must use the Set methods.
|
|
//
|
|
// Some types will automatically coerce and cause confusion,
|
|
// so they don't have constructors. You must use the Set
|
|
// method. These include:
|
|
// VT_UI2
|
|
// VT_UI4
|
|
// VT_UI8
