Last change on this file since 10629 was 10629, checked in by cinc, 21 years ago

Cinc:
o Rewrote VarNumFromParseNum()
o Added VarDecFromStr() from Wine.
o VarParseNumFromStr() updated with Wine code
o Updated DECIMAL struct (include\win\windef.h) to Wine level.

20 * NOTES
21 * This implements the low-level and hi-level APIs for manipulating VARIANTs.
22 * The low-level APIs are used to do data coercion between different data types.
23 * The hi-level APIs are built on top of these low-level APIs and handle
24 * initialization, copying, destroying and changing the type of VARIANTs.
25 *
26 * TODO:
27 * - The Variant APIs do not support international languages, currency
28 * types, number formating and calendar. They only support U.S. English format.
29 * - The Variant APIs do not the following types: IUknown, IDispatch, DECIMAL and SafeArray.
30 * The prototypes for these are commented out in the oleauto.h file. They need
31 * to be implemented and cases need to be added to the switches of the existing APIs.
32 * - The parsing of date for the VarDateFromStr is not complete.
33 * - The date manipulations do not support dates prior to 1900.
34 * - The parsing does not accept as many formats as the Windows implementation.
