VBScript VarType Function

The VarType function returns a value that indicates the subtype of a specified variable.

The VarType function can return one of the following values:

0 = vbEmpty - Indicates Empty (uninitialized)
1 = vbNull - Indicates Null (no valid data)
2 = vbInteger - Indicates an integer
3 = vbLong - Indicates a long integer
4 = vbSingle - Indicates a single-precision floating-point number
5 = vbDouble - Indicates a double-precision floating-point number
6 = vbCurrency - Indicates a currency
7 = vbDate - Indicates a date
8 = vbString - Indicates a string
9 = vbObject - Indicates an automation object
10 = vbError - Indicates an error
11 = vbBoolean - Indicates a boolean
12 = vbVariant - Indicates a variant (used only with arrays of Variants)
13 = vbDataObject - Indicates a data-access object
14 = vbDecimal - Indicates a decimal
17 = vbByte - Indicates a byte
20 = vbLongLong - Indicates a LongLong integer (valid on 64-bit platforms only)
36 = vbUserDefinedType - Indicates variants that contain user-defined types
8192 = vbArray - Indicates an array

Note: If the variable is an array VarType() returns 8192 + VarType(array_element). Example: for an array of integer VarType() will return 8192 + 2 = 8194.
