VBScript Constants
VBScript also presents a list of its own type constants, with values that you can use but will be unable to change. These constants correspond to the list of subtypes that we looked at earlier:
|
Constant |

VbNull |

VbInteger |
2 |

VbLong |
3 |
|
VbSingle |
4 |
|
VbDouble |
5 |
|
VbCurrency |
6 |
|
VbDate |
7 |
|
VbString |
8 |
|
VbObject |
9 |
|
VbError |
10 |
|
VbBoolean |
11 |
|
VbVariant |
12 |
|
VbDataObject |
13 |
|
VbByte |
17 |
|
VbArray |
8192 |
You can use these constants in the same way that you use variants; each of them represents the particular constant value indicated, although you cannot alter their values in any way.
There are literally hundreds of constants, which we can't cover here, and commonly they are stored in a separate file and then included in a page when needed. We look at the concept of using included information in chapter 10 .
