| 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. In many containers, colors are treated as 32-bit integers. Refer to Color for more information. |
| Date | DATE | DATE is a variant time that is stored as an 8-byte real value (double), representing 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 Windows 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. |
| Double | double | 64-bit floating point number. |
| Float | float | 32-bit floating point number. |
| Font | IFontDisp | An OLE Automation Interface to a font. Refer to Font for more information. |
| Integer | short | 16-bit signed integer. |
| IUnknown | IUnknown | A generic OLE interface. |

| Long | Long | 32-bit signed integer. |
| long | OLE_XPOS_PIXELS | Position on the X-axis in pixels. |
| Long | LCID | A locale identifier. |
| Long Array | SAFEARRAY(long) | An array of longs. |
| Object | IDispatch | A generic OLE Automation interface. |
| Object Array | SAFEARRAY | An array of objects. |
| Picture | IPicture | An OLE Automation Interface to a picture or image. Refer to Picture for more information. |
| Picture | IPictureDisp | An OLE Automation Interface to a picture or image. Refer to Picture for more information. |

| String Array | SAFEARRAY(BSTR) | An array of strings. |
| Variant | VARIANT | A variant. |
| VARTYPE | VARTYPE | An enumeration type used to describe a data type of a VARIANT or safearray value. Refer to VARTYPE for more information. |
