Per aprire un file esistente di Microsoft Excel, proteggere il libro con attributi di struttura e finestre e salvare il file.
Di seguito sono riportati frammenti di codice paralleli per VSTO (C#) e Aspose.Cells for .NET (C#) che mostrano come proteggere un workbook.
VSTO
Proteggere Workbook
//Instantiate the Application object.
Excel.Application excelApp = Application;
//Excel.Application excelApp = Application;
//Specify the template excel file path.
string myPath = "MyBook.xls";
//Open the excel file.
excelApp.Workbooks.Open(myPath, Missing.Value, Missing.Value,
Missing.Value, Missing.Value,
Missing.Value, Missing.Value,
Missing.Value, Missing.Value,
Missing.Value, Missing.Value,
Missing.Value, Missing.Value,
Missing.Value, Missing.Value);
//Protect the workbook specifying a password with Structure and Windows attributes.
excelApp.ActiveWorkbook.Protect("007", true, true);
//Save the file.
excelApp.ActiveWorkbook.Save();
//Quit the Application.
excelApp.Quit();
Disproteggere Workbook
//Unprotect the workbook specifying its password.
excelApp.ActiveWorkbook.Unprotect("007");
Aspose.Cells
Proteggere Workbook
//Specify the template excel file path.
string myPath = "Book1.xls";
//Instantiate a new Workbook.
//Open the excel file.
Workbook workbook = new Workbook(myPath);
//Protect the workbook specifying a password with Structure and Windows attributes.
workbook.Protect(ProtectionType.All, "007");
//Save As the excel file.
workbook.Save("MyBook.xls");
Disproteggere Workbook
//Unprotect the workbook specifying its password.
workbook.Unprotect("007");
