Hi fellow scripters,

Can someone direct me to the documentation of the variant types in the XSI documentations (if any).

I can figure out these one:

VT_BOOL = Boolean
VT_I1 = Byte
VT_I2 = Integer (short, 2 bytes)
VT_I4 = Integer (Long, 4 bytes)
VT_R4 = Single (32 bits, floating point numbers, 4 bytes)
VT_R8 = Double (64 bits, floating point numbers, 8 bytes)


I am not sure about those one:

VT_CY = Currency
VT_DATE = Date / time
VT_ERROR = Error
VT_EMPTY = Empty
VT_NULL = Null
VT_SAFEARRAY = Array of type
VT_DISPATCH = Object

What is the Variant Type (VT_) for:

String (VT_BSTR ??)
Array of Variant (VT_SAFEARRAY ???)
OLE Automation Object
Data Access Object


Thank you for your help!

Hello Everyone, me again.

Really what I need is a confirmation that the VARENUM used by XSI are as per the win32 and COM specification below.

Your help is greatly appreciated. Cheers!

OK, I think I found the answer. This should allow me to understand the Variant Type (VT_xx) code used in SPDLs and the type used in VBScript / JS / C++ / C#.

Here is the condense version from the SDK for future reference.

Cheers!
