Macro to loop in all sheets ...Please Help

Hiii Guys,,,

i need to run a macro in all the sheets in the workbook except the first sheet.

this is my macro

Sub DelDupRows()
    Dim rngSrc As Range
    Dim NumRows As Integer
    Dim ThisRow As Integer
    Dim ThatRow As Integer
    Dim ThisCol As Integer
    Dim RightCol As Integer
    Dim J As Integer, K As Integer
     
    Application.ScreenUpdating = False
    Set rngSrc = ActiveSheet.Range(ActiveWindow.Selection.Address)
     
    NumRows = rngSrc.Rows.Count
    ThisRow = rngSrc.Row
    ThatRow = ThisRow + NumRows - 1
    ThisCol = rngSrc.Column
    RightCol = ThisCol + rngSrc.Columns.Count - 1
     
     'Start wiping out duplicates
    For J = ThisRow To (ThatRow - 1)
        If Cells(J, ThisCol) > "" Then
            For K = (J + 1) To ThatRow
                If Cells(J, ThisCol) = Cells(K, ThisCol) Then
                    Cells(K, ThisCol) = ""
                End If
            Next K
        End If
    Next J
     
     'Remove rows with empty key cells
    For J = ThatRow To ThisRow Step -1
        If Cells(J, ThisCol) = "" Then
            Range(Cells(J, ThisCol), Cells(J, RightCol)).EntireRow.Delete xlShiftUp
        End If
    Next J
    Application.ScreenUpdating = True
End Sub

i tried so much...with for,count etc.. but its running only on the active sheet

kindly provide a solution
