Recently on the Ozgrid I was involved in a discussion about adding data to an Array after it has been filtered. If I use the current region as the Array's contents, Excel will include all of the data including the hidden data in the Array. Dim temporaryVariant () As Variant it will automatically pick up the cells as a 2-d array, without needing any funny business to avoid picking up the Range object. That should make it a lot easier to make your String () later. You should also cache the LBound () and UBound () results; it's faster (and less code) Q #3) How to convert Range to Array?
The size of the range/array is determined by the user through the arguments, therefore the easiest option for this is to use the Variant data type. A reasonable understanding of VBA arrays is required to change the UDF into a dynamic array compatible function. Check out my post about VBA arrays for further reading. Here is the updated UDF. 2012-01-31 · This post looks at a more general (and simpler) usage to return unique values from a worksheet range or VBA array.

For example, if you have the names of 100 employees, then instead of creating 100 variables of data type string, you can just create one array variable of type string and assign 100 values to the same array variable. You can use Data = VBA.Array(1, 2, 3) instead of Data = Array(1, 2, 3) to ensure that the array will always be zero-based (Option Base related). Is there a reason behind using Dim rg As Excel.Range instead of Dim rg As Range? Dim arShapes() As Variant Dim objRange As Object arShapes = Array("Oval 4", "Rectangle 5") Set objRange = ActiveSheet.Shapes.Range(arShapes) In Microsoft Excel, you cannot use this property to return a ShapeRange object containing all the Shape objects on a worksheet.
