55  * Variant-Formats {OLEAUT32}
56  *
57  * NOTES
58  * When formatting a variant a variety of format strings may be used to generate
59  * different kinds of formatted output. A format string consists of either a named
60  * format, or a user-defined format.
61  *
62  * The following named formats are defined:
63  *| Name Description
64  *| ---- -----------
65  *| General Date Display Date, and time for non-integer values
66  *| Short Date Short date format as defined by locale settings
67  *| Medium Date Medium date format as defined by locale settings
68  *| Long Date Long date format as defined by locale settings
69  *| Short Time Short Time format as defined by locale settings
70  *| Medium Time Medium time format as defined by locale settings
71  *| Long Time Long time format as defined by locale settings
72  *| True/False Localised text of "True" or "False"
73  *| Yes/No Localised text of "Yes" or "No"
74  *| On/Off Localised text of "On" or "Off"
75  *| General Number No thousands separator. No decimal points for integers
76  *| Currency General currency format using localised characters
77  *| Fixed At least one whole and two fractional digits
78  *| Standard Same as 'Fixed', but including decimal separators
79  *| Percent Multiply by 100 and display a trailing '%' character
80  *| Scientific Display with exponent
81  *
82  * User-defined formats consist of a combination of tokens and literal
83  * characters. Literal characters are copied unmodified to the formatted
84  * output at the position they occupy in the format string. Any character
85  * that is not recognised as a token is treated as a literal. A literal can
86  * also be specified by preceding it with a backslash character
87  * (e.g. "\L\i\t\e\r\a\l") or enclosing it in double quotes.
88  *
89  * A user-defined format can have up to 4 sections, depending on the type of
90  * format. The following table lists sections and their meaning:
91  *| Format Type Sections Meaning
92  *| ----------- -------- -------
93  *| Number 1 Use the same format for all numbers
94  *| Number 2 Use format 1 for positive and 2 for negative numbers
95  *| Number 3 Use format 1 for positive, 2 for zero, and 3
96  *| for negative numbers.
97  *| Number 4 Use format 1 for positive, 2 for zero, 3 for
98  *| negative, and 4 for null numbers.
99  *| String 1 Use the same format for all strings
100  *| String 2 Use format 2 for null and empty strings, otherwise
101  *| use format 1.
102  *| Date 1 Use the same format for all dates
103  *
104  * The formatting tokens fall into several categories depending on the type
105  * of formatted output. For more information on each type, see
106  * VarFormat-Dates(), VarFormat-Strings() and VarFormat-Numbers().
107  *

113 /******************************************************************************
114  * VarFormat-Strings {OLEAUT32}
115  *
116  * NOTES
117  * When formatting a variant as a string, it is first converted to a VT_BSTR.
118  * The user-format string defines which characters are copied into which
119  * positions in the output string. Literals may be inserted in the format
120  * string. When creating the formatted string, excess characters in the string
121  * (those not consumed by a token) are appended to the end of the output. If
122  * there are more tokens than characters in the string to format, spaces will
123  * be inserted at the start of the string if the '@' token was used.
124  *
125  * By default strings are converted to lowercase, or uppercase if the '>' token
126  * is encountered. This applies to the whole string: it is not possible to
127  * generate a mixed-case output string.
128  *
129  * In user-defined string formats, the following tokens are recognised:
130  *| Token Description
131  *| ----- -----------
132  *| '@' Copy a char from the source, or a space if no chars are left.
133  *| '&' Copy a char from the source, or write nothing if no chars are left.
134  *| '<' Output the whole string as lower-case (the default).
135  *| '>' Output the whole string as upper-case.
136  *| '!' MSDN indicates that this character should cause right-to-left
137  *| copying, however tests show that it is tokenised but not processed.
