How to get the range of the visible rows after applying an advanced filter in Excel (VBA)

Question

Here is the code that applies an advanced filter to the column A on the Sheet1 worksheet (List range) by using the range of values on the Sheet2 (criteria range):

Answer 1

You can use the following code to get the visible range of cells:

Excel.Range visibleRange = Excel.Application.ActiveWindow.VisibleRange

Hope this helps.

Answer 2

Lance's solution will work in the majority of situations.

But if you deal with large/complex spreadsheets you might run into the "SpecialCells Problem". In a nutshell, if the range created causes greater than 8192 non-contiguous areas (and it can happen) then Excel will throw an error when you attempt to access SpecialCells and your code won't run. If your worksheets are complex enough you expect to encounter this problem, then it is recommended you stick with the looping approach.

It's worth noting that this problem is not with the SpecialCells property itself, rather it is with the Range object. This means that anytime that you attempt to obtain a range object that could be very complex you should either employee an error handler, or do as you already have done, which is to cause your program to work on each element of the range (split the range up).

Another possible approach would be to return an array of Range Objects and then loop through the array. I have posted some example code to play around with. However it should be noted that you really should only bother with this if you expect to have the problem described or you just want to feel assured your code is robust. Otherwise it's just needless complexity.

Answer 3

ActiveSheet.Range("A1:A100").Rows.SpecialCells(xlCellTypeVisible)

This yields a Range object.
