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 *

110 * VarFormatDateTime(), VarFormatNumber(), VarFormatCurrency().

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.
