TypeName
Description Returns a string that provides Variant subtype information about a variable.
Usage TypeName(varname)
Arguments varname
The required varname argument can be any variable.
Return A String. The TypeName function has the following return values:
Value Description
Byte Byte value
Integer Integer value
Long Long integer value
Single Single-precision floating-point value
Double Double-precision floating-point value
Currency Currency value
Decimal Decimal value
Date Date or time value
String Character string value
Boolean Boolean value; True or False
Empty Uninitialized
Null No valid data
Actual type name of an object
Object Generic object
Unknown Unknown object type
Nothing Object variable that doesn't yet refer to an object instance
Error Error
See Also IsArray, IsDate, IsEmpty, IsNull, IsNumeric, IsObject, VarType
Example The following example uses the TypeName function to return information about a variable:
Dim ArrayVar(4), MyType
NullVar = Null ' Assign Null value.
MyType = TypeName("VBScript") ' Returns "String".
MyType = TypeName(4) ' Returns "Integer".
MyType = TypeName(37.50) ' Returns "Double".
MyType = TypeName(NullVar) ' Returns "Null".
MyType = TypeName(ArrayVar) ' Returns "Variant()".
UBound
Description Returns the largest available subscript for the indicated dimension of an array.
Usage IntVal = UBound(arrayname[, dimension])
Arguments arrayname
Name of the array variable; follows standard variable naming conventions.
dimension
Optional whole (integer) number indicating which dimension's upper bound is returned. Use 1
for the first dimension, 2 for the second, and so on. If dimension is omitted, 1 is assumed.
Returns Returns the largest available subscript for the indicated dimension of an array. If the array is
empty, -1 is returned. If the array has not been initialized, a runtime error will occur.
Remarks The UBound function is used with the LBound function to determine the size of an array. Use
the LBound function to find the lower limit of an array dimension. The lower bound for any
dimension is always 0.
See also Dim, LBound, ReDim
Example Dim A(100,3,4)
Dim B(3)
myVal = UBound(A,1) ‘ Return value = 100
myVal = UBound(A,2) ‘ Return value = 3
myVal = UBound(A,3) ‘ Return value = 4
myVal = UBound(B) ‘ Return value = 3
