* VARIANT
|
|
*
|
|
* Copyright 1998 Jean-Claude Cote
|
|
*
|
|
* NOTES
|
|
* This implements the low-level and hi-level APIs for manipulating VARIANTs.
|
|
* The low-level APIs are used to do data coercion between different data types.
|
|
* The hi-level APIs are built on top of these low-level APIs and handle
|
|
* initialization, copying, destroying and changing the type of VARIANTs.
|
|
*
|
|
* TODO:
|
|
* - The Variant APIs do not support international languages, currency
|
|
* types, number formating and calendar. They only support U.S. English format.
|
|
* - The Variant APIs do not the following types: IUknown, IDispatch, DECIMAL and SafeArray.
|
|
* The prototypes for these are commented out in the oleauto.h file. They need
|
|
* to be implemented and cases need to be added to the switches of the existing APIs.
|
|
* - The parsing of date for the VarDateFromStr is not complete.
|
|
* - The date manipulations do not support dates prior to 1900.
|
|
* - The parsing does not accept as many formats as the Windows implementation.
