TypeName Function
Description
Returns a String that provides information about a variable.
Syntax
TypeName(varname)
The required varname argument is a Variant containing any variable except a variable of a user-defined type.
Remarks
The string returned by TypeName can be any one of the following:
String returned | Variable |
|
object type | An object whose type is objecttype |
Byte | Byte value |
Integer | Integer |
Long | Long integer |
Single | Single-precision floating-point number |
Double | Double-precision floating-point number |
Currency | Currency value |
Decimal | Decimal value |
Date | Date value |
String | String |
Boolean | Boolean value |
Error | An error value |
Empty | Uninitialized |
Null | No valid data |
Object | An object |
Unknown | An object whose type is unknown |
Nothing | Object variable that doesn't refer to an object |
If varname is an array, the returned string can be any one of the possible returned strings (or Variant) with empty parentheses appended. For example, if varname is an array of integers, TypeName returns "Integer()".

Example
This example uses the TypeName function to return information about a variable.
' Declare variables.
Dim NullVar, MyType, StrVar As String, IntVar As Integer, CurVar As Currency
Dim ArrayVar (1 To 5) As Integer
NullVar = Null ' Assign Null value.
MyType = TypeName(StrVar) ' Returns "String".
MyType = TypeName(IntVar) ' Returns "Integer".
MyType = TypeName(CurVar) ' Returns "Currency".
MyType = TypeName(NullVar) ' Returns "Null".
MyType = TypeName(ArrayVar) ' Returns "Integer()".
Example (Microsoft Access)
The following example creates several object variables and passes them to the TypeName function.
Sub ObjectTypes()
Dim dbs As Database, tdf As TableDef
Dim fld As Field
' Get current database.
Set dbs = CurrentDb
' Return TableDef object pointing to Orders table.
Set tdf = dbs.TableDefs("Orders")
' Return Field object pointing to OrderDate field.
Set fld = tdf.Fields("OrderDate")
' Print value returned by TypeName for each object.
Debug.Print TypeName(dbs)
Debug.Print TypeName(tdf)
Debug.Print TypeName(fld)
End Sub
Example (Microsoft Excel)
This example displays the Visual Basic object type of the selection. You can run this example with cells selected, with a single oval selected, or with several different graphic objects selected.
Worksheets("Sheet1").Activate
MsgBox "The selection object type is " & TypeName(Selection)
