Description
The CsvFieldDef property is the most important property in the CSVDataSet. You MUST set it up (using the property editor or by typing a valid CsvFieldDef string) before you can use the CSV Data Set.
A CsvFieldDef string is a comma separated list of field names. After each field name, an optional colon may be used to separate the field name from field options, which are described below.
- Fieldname must start with a Letter (A-Z) and can contain Letters, Numbers and Underscores.
- Field Types are described below. $ is a string. Other punctuation indicates other types.
- Length ONLY applies to string fields.
| Field Types Meaning ----------- |
| $ string (ftString) - also used if no character is given. May be followed by the length, a length of 80 is assumed if "$" is used without a specific length (For example, ABC:$100 is a field named ABC, type string, string length 100). |
| % whole integer value (ftInteger) & floating point value (ftFloat) @ Ascii datetime value (ftDateTime) as YYYY/MM/DD HH:MM:SS (Component Specific) # |
| Hex-Ascii Timestamp (A93F38C9) seconds since Jan 1, 1970 GMT (Component Specific) ^ Hex-Ascii Timestamp (A93F38CP) corrected to local timezone |
| (Component Specific) ! Boolean Field (0 in csv file=false, not 0 = true, blank = |
| NULL) |
CsvFieldDef string Example: NAME:$80,ADDRESS:$140,AGE:%,BIRTHDAY:@
