Type | OLE Automation Type | Description |
---|---|---|
Boolean | VARIANT_BOOL | Has the value True (-1) or False (0). |
Byte Array | SAFEARRAY(unsigned char) | An array of bytes. |
Color | OLE_COLOR | A color. Many containers treat colors as 32-bit integers. |
Date | DATE | DATE is a variant time that is stored as an 8-byte real value (double) and represents a date between January 1, 100 and December 31, 9999, inclusive. The value 0 represents December 30, 1899. Adding 1 to the value increments the date by a day. The fractional part of the value represents the time of day. Negative numbers represent the dates before December 30, 1899. LabWindows/CVI users can use the VariantTimeToSystemTime Microsoft Windows Software Development Kit (SDK) function to convert the variant date to a system time value and then use the GetDateFormat and GetTimeFormat Windows SDK functions to generate display strings. LabVIEW automatically converts the DATE data type to a timestamp. |
