We have already demonstrated how to using Spire.XLS hide excel columns and rows in C#. Sometimes we don't want to show the data on a certain cell to others but not hide the whole row or column. Then we can only hide the data on this cell by setting the number format for it. This article will focus on showing how to hide the content on a certain cell by setting the number format as ";;;" to hide the content to others.
Step 1: Initialize an instance of Workbook and load the document from file.
Workbook workbook = new Workbook();
workbook.LoadFromFile("Sample.xlsx");
Step 2: Get the first worksheet from the workbook.
Worksheet worksheet = workbook.Worksheets[0];
Step 3: Hide the area by setting the number format as ";;;".
worksheet.Range["E2"].NumberFormat = ";;;";
Step 4: Save the document to file.
workbook.SaveToFile("Result.xlsx", FileFormat.Version2010);
Effective screenshot of hide the content on Excel cell by setting the number format:

Lock Specified Sections of Word Documents in C#, VB.NET
2017-03-15 08:04:50 Written by AdministratorSection protection allows users to be able to edit only the forms (if any) rather than any other content within it. When we protect a document, we can specify that the specific sections of the document be protected. This is useful in case we want to protect parts of a Word document.
Following code snippets demonstrate the same.
Step 1: Initialize an instance of Document class.
Document doc = new Document();
Step 2: Add two sections to the document.
Section s1 = doc.AddSection(); Section s2 = doc.AddSection();
Step 3: Append some text to section 1 and section 2.
s1.AddParagraph().AppendText("section 1");
s2.AddParagraph().AppendText("section 2");
Step 4: Protect the document with AllowOnlyFormFields protection type.
doc.Protect(ProtectionType.AllowOnlyFormFields, "123");
Step 5: Unprotect section 2.
s2.ProtectForm = false;
Step 6: Save the document.
doc.SaveToFile("Protect_Section.docx");
Result:
Run the program, we should get the file in which section 1 is protected to allow only editing in form fields while section 2 can be edited freely.
Full Code:
using Spire.Doc;
namespace LockSection
{
class Program
{
static void Main(string[] args)
{
Document doc = new Document();
Section s1 = doc.AddSection();
Section s2 = doc.AddSection();
s1.AddParagraph().AppendText("section 1");
s2.AddParagraph().AppendText("section 2");
//protect all sections
doc.Protect(ProtectionType.AllowOnlyFormFields, "123");
//unprotect section 2
s2.ProtectForm = false;
doc.SaveToFile("Protect_Section.docx");
}
}

A Sound action is used to embed and play a sound file in PDF document. In Spire.PDF, we can create a sound action by using the PdfSoundAction class. Attributes like sound, volume and repeat can be specified for the sound action.
Refer below code example:
Step 1: Create a new PDF document and add a page to it.
PdfDocument document = new PdfDocument(); PdfPageBase page = document.Pages.Add();
Step 2: Create a sound action and set its attributes.
PdfSoundAction soundAction = new PdfSoundAction(@"C:\Users\Administrator\Desktop\because of you.wav"); soundAction.Sound.Bits = 15; soundAction.Sound.Channels = PdfSoundChannels.Stereo; soundAction.Sound.Encoding = PdfSoundEncoding.Signed; soundAction.Volume = 0.8f; soundAction.Repeat = true;
Step 3: Set the sound action to be executed when the PDF document is opened.
document.AfterOpenAction = soundAction;
Step 4: Save and close the PDF document.
document.SaveToFile("Output.pdf");
document.Close();
Full code:
using Spire.Pdf;
using Spire.Pdf.Actions;
using Spire.Pdf.General;
namespace PDF_Sound_Action

{
static void Main(string[] args)
{
//Create a new PDF document
PdfDocument document = new PdfDocument();
//Add a page
PdfPageBase page = document.Pages.Add();
//Create a sound action
PdfSoundAction soundAction = new PdfSoundAction(@"C:\Users\Administrator\Desktop\because of you.wav");
soundAction.Sound.Bits = 15;
soundAction.Sound.Channels = PdfSoundChannels.Stereo;
soundAction.Sound.Encoding = PdfSoundEncoding.Signed;
soundAction.Volume = 0.8f;
soundAction.Repeat = true;
// Set the sound action to be executed when the PDF document is opened
document.AfterOpenAction = soundAction;
//Save and close the PDF document
