VarType function
Returns an Integer indicating the subtype of a variable, or the type of an object's default property.
Syntax
VarType(varname)
The required varname argument is a Variant containing any variable except a variable of a user-defined type.
Return values
Either one of the following constants or the summation of a number of them is returned.
| Constant | Value | Description |
|---|---|---|
| vbEmpty | 0 | Empty (uninitialized) |
| vbNull | 1 | Null (no valid data) |
| vbInteger | 2 | Integer |
| vbLong | 3 | Long integer |
| vbSingle | 4 | Single-precision floating-point number |
| vbDouble | 5 | Double-precision floating-point number |
| vbCurrency | 6 | Currency value |
| vbDate | 7 | Date value |
| vbString | 8 | String |
| vbObject | 9 | Object |
| vbError | 10 | Error value |
| vbBoolean | 11 | Boolean value |
| vbVariant | 12 | Variant (used only with arrays of variants) |
| vbDataObject | 13 | A data access object |
| vbDecimal | 14 | Decimal value |
| vbByte | 17 | Byte value |
| vbLongLong | 20 | LongLong integer (valid on 64-bit platforms only) |
| vbUserDefinedType | 36 | Variants that contain user-defined types |
| vbArray | 8192 | Array (always added to another constant when returned by this function) |
Note
These constants are specified by Visual Basic for Applications. The names can be used anywhere in your code in place of the actual values.
Remarks
If an object is passed and has a default property, VarType(object) returns the type of the object's default property.
The VarType function never returns the value for vbArray by itself. It's always added to some other value to indicate an array of a particular type. For example, the value returned for an array of integers is calculated as vbInteger + vbArray, or 8194.
The constant vbVariant is only returned in conjunction with vbArray to indicate that the argument to the VarType function is an array of type Variant.
Example
This example uses the VarType function to determine the subtypes of different variables, and in one case, the type of an object's default property.
Dim MyCheck
Dim IntVar, StrVar, DateVar, AppVar, ArrayVar
' Initialize variables.
IntVar = 459: StrVar = "Hello World": DateVar = #2/12/1969#
Set AppVar = Excel.Application
ArrayVar = Array("1st Element", "2nd Element")
' Run VarType function on different types.
MyCheck = VarType(IntVar) ' Returns 2.
MyCheck = VarType(DateVar) ' Returns 7.
MyCheck = VarType(StrVar) ' Returns 8.
MyCheck = VarType(AppVar) ' Returns 8 (vbString)
' even though AppVar is an object.
MyCheck = VarType(ArrayVar) ' Returns 8204 which is
' `8192 + 12`, the computation of
' `vbArray + vbVariant`.
