Method 1: Unprotect the Worksheet

If the SpecialCells method is used on a worksheet with the contents protected, the macro produces the error message described in the "Symptoms" section. To avoid this error message, unprotect the sheet before using the SpecialCells method. Reapply the protection after the cells have been selected. This sample macro unprotects the sheet, selects all blank cells in the used range, and then protects the sheet:
Sub Test3()
   ActiveSheet.Unprotect
   Selection.SpecialCells(xlCellTypeBlanks).Select
   ActiveSheet.Protect DrawingObjects:=True, Contents:=True, _
      Scenarios:=True
End Sub
				
NOTE: If the worksheet is protected by a password, you must supply the password as an argument for the Unprotect method.

Method 2: Use the SendKeys Statement

The SpecialCells constant xlCellTypeLastCell has a keyboard equivalent that can be selected by pressing a specific key combination. You can use this constant to select the last cell in the used range by using the SpecialCells method. This operation can be simulated on the worksheet by pressing CTRL+END. Using the SendKeys statement, a macro can simulate this key combination.

The following sample macro provides a simulation of pressing CTRL+END, and it operates when the worksheet contents are protected:
Sub Test1()
   Application.SendKeys "^{END}"
End Sub
