Removes protection from a ChartSheetBase. This method has no effect if the sheet or workbook is not protected.

public void Unprotect (object password);

member this.Unprotect : obj -> unit

Public Sub Unprotect (Optional password As Object)

Parameters

password: Object

The case-sensitive password to use to unprotect the sheet or workbook. If the sheet or workbook is not protected with a password, this argument is ignored. If you omit this argument for a sheet that is protected with a password, you will be prompted for the password. If you omit this argument for a workbook that is protected with a password, the method fails.

Examples

The following code example uses the Protect method to protect all contents of the current Microsoft.Office.Tools.Excel.ChartSheetBase. The example then uses the ProtectContents property to verify that the chart sheet is protected, and then prompts the user to remove protection from the chart sheet by using the Unprotect method.

private void ChartSheetProtection()
{
    Globals.Sheet1.Range["A1", "A5"].Value2 = 22;
    Globals.Sheet1.Range["B1", "B5"].Value2 = 55;

    this.SetSourceData(Globals.Sheet1.Range["A1", "B5"],
        Excel.XlRowCol.xlColumns);
    this.ChartType = Excel.XlChartType.xl3DColumn;

    this.Protect(true, true, true, false);

    if (this.ProtectContents)
    {
        if (DialogResult.Yes ==
            MessageBox.Show("The chart sheet is protected. " +
            "Unprotect the chart sheet?", "Example", 
            MessageBoxButtons.YesNo))
        {
            this.Unprotect();
        }
    }
}

Private Sub ChartSheetProtection()
    Globals.Sheet1.Range("A1", "A5").Value2 = 22
    Globals.Sheet1.Range("B1", "B5").Value2 = 55

    Me.SetSourceData(Globals.Sheet1.Range("A1", "B5"), _
        Excel.XlRowCol.xlColumns)
    Me.ChartType = Excel.XlChartType.xl3DColumn

    Me.Protect(DrawingObjects:=True, Contents:=True, _
        Scenarios:=True, UserInterfaceOnly:=False)

    If Me.ProtectContents Then
        If DialogResult.Yes = MessageBox.Show("The chart sheet" & _
            " is protected. Unprotect the chart sheet?", _
            "Example", MessageBoxButtons.YesNo) Then
            Me.Unprotect()
        End If
    End If
End Sub

Remarks

If you forget the password, you cannot unprotect the Microsoft.Office.Tools.Excel.ChartSheetBase. It is a good idea to keep a list of your passwords and their corresponding document names in a safe place.
