Index1(1) = 1

Index1(2) = 1

Index2(1) = 3

Index2(2) = 2

x(Index1, Index2, 2, "red") = 0.5

The last statement resolves to:

x(1, 1, 3, 2, 2, "red") = 0.5

• The field name must be the last index in the list. The following statement

produces an error:

y = x("blue", 1, 2)

• Field names are case sensitive.

Property NumberOfFields As Long

The read-only NumberOfFields property returns the number of fields in the

structure array.

Property NumberOfDims As Long

The read-only NumberOfDims property returns the number of dimensions in the

struct array.

Property Dims As Variant

The read-only Dims property returns an array of length NumberOfDims that

contains the size of each dimension of the struct array.

Property FieldNames As Variant

The read-only FieldNames property returns an array of length NumberOfFields

that contains the field names of the elements of the structure array.

Example. The next Visual Basic code sample illustrates how to access a

two-dimensional structure array’s fields when the field names and dimension

sizes are not known in advance.

Sub foo ()

Dim x As MWStruct

Dim Dims as Variant

Dim FieldNames As Variant

1 2 ... 159 160 161 162 163 164 165 166 167 168 169 ... 181 182
