Question

Is there there any code in Excel 2010 VBA that I can use to hide row n (e.g. row 200) to the maximum row?

Btw the name of the sheet in particular is main.

Answer 1

Updated comment: To be clear I interpreted this question as hiding from row 200 to the used row with data (if that last used row exceeded 200)

Something like this

code

Sub HideEm()
    Dim rng1 As Range
    Set rng1 = ActiveSheet.Cells.Find("*", [a1], xlValues, , , xlPrevious)
    If Not rng1 Is Nothing Then
        If rng1.Row > 200 Then Rows("200:" & rng1.Row).Hidden = True
    End If
End Sub

to work on a specific sheet

Sub HideEm()
Dim ws As Worksheet
Dim rng1 As Range
Set ws = Sheets("main")
Set rng1 = ws.Cells.Find("*", ws.[a1], xlValues, , , xlPrevious)
If Not rng1 Is Nothing Then
    If rng1.Row > 200 Then ws.Rows("200:" & rng1.Row).Hidden = True
End If
End Sub
