VBScript VarType Function
Definition and Usage
The VarType function can return a value indicating the sub-type of the specified variable.
Values that the VarType function can return:
| Constant | Value | Description |
|---|---|---|
| vbEmpty | 0 | Not initialized (default) |
| vbNull | 1 | Does not contain any valid data |
| vbInteger | 2 | Integer sub-type |
| vbLong | 3 | Long integer sub-type |
| vbSingle | 4 | Single precision sub-type |
| vbDouble | 5 | Double precision sub-type |
| vbCurrency | 6 | Currency sub-type |
| vbDate | 7 | Date or Time value |
| vbString | 8 | String Value |
| vbObject | 9 | String Subtype |
| vbError | 10 | Error Subtype |
| vbBoolean | 11 | Boolean Subtype |
| vbVariant | 12 | Variant (only for variable arrays) |
| vbDataObject | 13 | Data Access Object |
| vbDecimal | 14 | Decimal Subtype |
| vbByte | 17 | Byte Subtype |
| vbArray | 8192 | Array |
Note:These constants are specified by VBScript. Therefore, these names can be used anywhere in the code to represent actual values.
Note:If the variable is an array, VarType() will return 8192 + VarType(array element). For example, the VarType() of an integer array will return 8192 + 2 = 8194.
