Description
This method deletes count columns from an XArrayDB object starting at column index and returns the number of columns successfully deleted.
Example
The following example initializes an XArrayDB object with 10 rows and 6 columns, then removes the fourth and fifth columns:
MyArray.ReDim 1, 10, 1, 6
Dim i, j As Integer
For i = 1 To 10
For j = 1 To 6
MyArray(i, j) = "Row " & i & ", Col " & j
Next j
Next i
Debug.Print MyArray(1, 4) ' prints Row 1, Col 4
Debug.Print MyArray(1, 5) ' prints Row 1, Col 5
' remove two columns starting at index 4
Dim result As Long
result = MyArray.DeleteColumns(4, 2)
Debug.Print result ' prints 2
Debug.Print MyArray.Count(2) ' prints 4
Debug.Print MyArray(1, 4) ' prints Row 1, Col 6
' the next line now gives a "Subscript out of range" error
Debug.Print MyArray(1, 5)
