66 * Variant-Formats {OLEAUT32}
67 *
68 * NOTES
69 * When formatting a variant a variety of format strings may be used to generate
70 * different kinds of formatted output. A format string consists of either a named
71 * format, or a user-defined format.
72 *
73 * The following named formats are defined:
74 *| Name Description
75 *| ---- -----------
76 *| General Date Display Date, and time for non-integer values
77 *| Short Date Short date format as defined by locale settings
78 *| Medium Date Medium date format as defined by locale settings
79 *| Long Date Long date format as defined by locale settings
80 *| Short Time Short Time format as defined by locale settings
81 *| Medium Time Medium time format as defined by locale settings
82 *| Long Time Long time format as defined by locale settings
83 *| True/False Localised text of "True" or "False"
84 *| Yes/No Localised text of "Yes" or "No"
85 *| On/Off Localised text of "On" or "Off"
86 *| General Number No thousands separator. No decimal points for integers
87 *| Currency General currency format using localised characters
88 *| Fixed At least one whole and two fractional digits
89 *| Standard Same as 'Fixed', but including decimal separators
90 *| Percent Multiply by 100 and display a trailing '%' character
91 *| Scientific Display with exponent
92 *
93 * User-defined formats consist of a combination of tokens and literal
94 * characters. Literal characters are copied unmodified to the formatted
95 * output at the position they occupy in the format string. Any character
96 * that is not recognised as a token is treated as a literal. A literal can
97 * also be specified by preceeding it with a backslash character
98 * (e.g. "\L\i\t\e\r\a\l") or enclosing it in double quotes.
99 *
100 * A user-defined format can have up to 4 sections, depending on the type of
101 * format. The following table lists sections and their meaning:
102 *| Format Type Sections Meaning
103 *| ----------- -------- -------
104 *| Number 1 Use the same format for all numbers
105 *| Number 2 Use format 1 for positive and 2 for negative numbers
106 *| Number 3 Use format 1 for positive, 2 for zero, and 3
107 *| for negative numbers.
108 *| Number 4 Use format 1 for positive, 2 for zero, 3 for
109 *| negative, and 4 for null numbers.
110 *| String 1 Use the same format for all strings
111 *| String 2 Use format 2 for null and empty strings, otherwise
112 *| use format 1.
113 *| Date 1 Use the same format for all dates
114 *
115 * The formatting tokens fall into several categories depending on the type
116 * of formatted output. For more information on each type, see
117 * VarFormat-Dates(), VarFormat-Strings() and VarFormat-Numbers().
118 *
119 * SEE ALSO
120 * VarTokenizeFormatString(), VarFormatFromTokens(), VarFormat(),
121 * VarFormatDateTime(), VarFormatNumber(), VarFormatCurrency().

124 /******************************************************************************
125 * VarFormat-Strings {OLEAUT32}
126 *
127 * NOTES
128 * When formatting a variant as a string, it is first converted to a VT_BSTR.
129 * The user-format string defines which characters are copied into which
130 * positions in the output string. Literals may be inserted in the format
131 * string. When creating the formatted string, excess characters in the string
132 * (those not consumed by a token) are appended to the end of the output. If
133 * there are more tokens than characters in the string to format, spaces will
134 * be inserted at the start of the string if the '@' token was used.
135 *
136 * By default strings are converted to lowercase, or uppercase if the '>' token
137 * is encountered. This applies to the whole string: it is not possible to
138 * generate a mixed-case output string.
139 *
140 * In user-defined string formats, the following tokens are recognised:
141 *| Token Description
142 *| ----- -----------
143 *| '@' Copy a char from the source, or a space if no chars are left.
144 *| '&' Copy a char from the source, or write nothing if no chars are left.
145 *| '<' Output the whole string as lower-case (the default).
146 *| '>' Output the whole string as upper-case.
147 *| '!' MSDN indicates that this character should cause right-to-left
148 *| copying, however tests show that it is tokenised but not processed.
