Iterating through all the cells in Excel VBA or VSTO 2005

Question

I need to simply go through all the cells in a Excel Spreadsheet and check the values in the cells. The cells may contain text, numbers or be blank. I am not very familiar

Answer 1

Sub CheckValues1()
    Dim rwIndex As Integer
    Dim colIndex As Integer
    For rwIndex = 1 To 10
            For colIndex = 1 To 5
                If Cells(rwIndex, colIndex).Value <> 0 Then _
                    Cells(rwIndex, colIndex).Value = 0
            Next colIndex
    Next rwIndex
End Sub

Found this snippet on http://www.java2s.com/Code/VBA-Excel-Access-Word/Excel/Checksvaluesinarange10rowsby5columns.htm It seems to be quite useful as a function to illustrate the means to check values in cells in an ordered fashion.

Just imagine it as being a 2d Array of sorts and apply the same logic to loop through cells.
