Spire.Doc supports to insert any type of file such as Excel, PDF, PowerPoint and etc, as OLE object into a Word document. In this article, you'll learn how to add a media file (audio or video) to a Word document using Spire.Doc in C#, VB.NET.
In the class of DocOleObject, a method named AppendOleObject(Stream oleStream, DocPicture olePicture, string fileExtension) is available for users to insert media file with the extension of mp3, mp4, avi or any other format into a Word document. The three parameters in this method represent:
- oleStream: The OLE file stream.
- olePicture: The image (icon) that is displayed in Word to show the OLE object.
- fileExtension: The file extension.
Code Snippet:
Step 1: Initialize a new instance of Document class and add a new section.
Document doc = new Document(); Section section = doc.AddSection();
Step 2: Add a new paragraph, append some formatted text into the paragraph.
Paragraph para1 = section.AddParagraph();
para1.AppendText("Double click the PLAY button to view the video file");
ParagraphStyle style1 = new ParagraphStyle(doc);
style1.Name = "Style";
style1.CharacterFormat.FontName = "Calibri";
style1.CharacterFormat.FontSize = 15;
style1.CharacterFormat.Bold = true;
style1.CharacterFormat.TextColor = Color.Red;
doc.Styles.Add(style1);
para1.ApplyStyle(style1.Name);
Step 3: Add another paragraph, append a video file as OLE object into the paragraph.
Paragraph para2 = section.AddParagraph();
Stream s = File.OpenRead("media.mp4");
DocPicture pic = new DocPicture(doc);
pic.LoadImage(Image.FromFile("button.png"));
para2.AppendOleObject(s, pic, "mp4");
Step 4: Save the view the file.
doc.SaveToFile("Result.docx", FileFormat.Docx2010);
System.Diagnostics.Process.Start("Result.docx");

How to Mark a Presentation as Final using Spire.Presentation in C#, VB.NET
2015-08-06 05:54:52 Written by KoohjiThe Mark as Final command makes a presentation read-only and prevents changes to the document. When you share a presentation that is marked as final, you're telling viewers the presentation is final and no changes on it are wanted. In this article, I'll make a brief introduction about how to mark a presentation as final using Spire.Presentation in C#, VB.NET.
In Spire.Presentation, the presentation class contains a property of DocumentProperty which enables developers to set document properties easily. Here in this case, you are able to mark a presentation as final by setting the Boolean value of MarkAsFinal as true.
Code Snippet:
Step 1: Initialize a new instance of presentation class and load the sample file.
Presentation ppt = new Presentation();
ppt.LoadFromFile("sample.pptx",FileFormat.Pptx2010);
Step 2: Set the value of MarkAsFinal property as true.
ppt.DocumentProperty["_MarkAsFinal"] =true;
Step 3: Save and launch the file.
ppt.SaveToFile("result.pptx",FileFormat.Pptx2010);
System.Diagnostics.Process.Start("result.pptx");
Effect:
Full Code:
using Spire.Presentation;
namespace MarkPPT
{
class Program
{
static void Main(string[] args)
{
Presentation ppt = new Presentation();
ppt.LoadFromFile("sample.pptx", FileFormat.Pptx2010);
ppt.DocumentProperty["_MarkAsFinal"] = true;
ppt.SaveToFile("result.pptx", FileFormat.Pptx2010);
System.Diagnostics.Process.Start("result.pptx");
System.Diagnostics.Process.Start("result.pptx");
}
}
}
Imports Spire.Presentation
Namespace MarkPPT
Class Program
Private Shared Sub Main(args As String())
Dim ppt As New Presentation()
ppt.LoadFromFile("sample.pptx", FileFormat.Pptx2010)
ppt.DocumentProperty("_MarkAsFinal") = True
ppt.SaveToFile("result.pptx", FileFormat.Pptx2010)
System.Diagnostics.Process.Start("result.pptx")
System.Diagnostics.Process.Start("result.pptx")

Inserting paragraphs in Word is a fundamental skill for creating well-structured and organized documents. Paragraphs can break down large blocks of text, making it easier for readers to follow the flow of ideas and find specific information. In Word, you can add new paragraphs to represent new ideas or add additional information. This article will demonstrate how to insert a new paragraph in Word in C# using Spire.Doc for .NET.
- Add a Paragraph at the End of a Word Document in C#
- Insert a Paragraph at a Specified Location in Word in C#
Install Spire.Doc for .NET
To begin with, you need to add the DLL files included in the Spire.Doc for .NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.
PM> Install-Package Spire.Doc
Add a Paragraph at the End of a Word Document in C#
To add a new paragraph at the end, you need to get the last section of the Word document through the Document.LastSection property, and then add a paragraph at the end of the section through the Section.AddParagraph() method. The following are the detailed steps:
- Create a Document instance.
- Load a Word document using Document.LoadFromFile() method.
- Get the last section of the document using Document.LastSection property.
- Add a paragraph at the end of the section using Section.AddParagraph() method, and then add text to it using Paragraph.AppendText() method.
- Create a ParagraphStyle object and set the font name, size, style of the paragraph text.
- Apply the paragraph style using Paragraph.ApplyStyle() method
- Save the result document using Document.SaveToFile() method.
- C#
using Spire.Doc;
using Spire.Doc.Documents;
using System.Drawing;
namespace AddParagraph
{
class Program
{
static void Main(string[] args)
{
//Create a Document object
Document doc = new Document();
//Load a Word document
doc.LoadFromFile("Test.docx");
//Get the last section
Section section = doc.LastSection;
//Add a paragraph at the end and set its text content
Paragraph para = section.AddParagraph();
para.AppendText("Add a paragraph to the end of the document.");
//Set the paragraph style
ParagraphStyle style = new ParagraphStyle(doc);
style.Name = "Style1";
style.CharacterFormat.FontName = "Times New Roman";
style.CharacterFormat.FontSize = 12;
style.CharacterFormat.TextColor = Color.Blue;
style.CharacterFormat.Bold = true;
doc.Styles.Add(style);
para.ApplyStyle("Style1");
para.Format.BeforeSpacing = 10;
//Save the result file
doc.SaveToFile("AddParagraph.docx", FileFormat.Docx2016);
}
}
}
Insert a Paragraph at a Specified Location in Word in C#
You can also add a paragraph and then insert it to a specified position through the Section.Paragraphs.Insert(int index, IParagraph paragraph) method. The following are the detailed steps:
- Create a Document instance.
- Load a Word document using Document.LoadFromFile() method.
- Get a specified section using Document.Sections[] property.
- Add a paragraph using Section.AddParagraph() method, and then add text to it using Paragraph.AppendText() method.
- Set the font name, size, style of the paragraph text.
- Insert the newly added paragraph at a specified index using Section.Paragraphs.Insert(int index, IParagraph paragraph) method.
- Save the result document using Document.SaveToFile() method.
- C#
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
using System.Drawing;
namespace InsertParagraph
{
class Program
{
static void Main(string[] args)
{
//Create a Document object
Document doc = new Document();
//Load a Word document
doc.LoadFromFile("Test.docx");
//Get the first section
Section section = doc.Sections[0];
//Add a paragraph and set its text content
Paragraph para = section.AddParagraph();
TextRange textRange = para.AppendText("Insert a paragraph at a specified location in the Word document.");
//Set the font name, size, color and style
textRange.CharacterFormat.TextColor = Color.Blue;
textRange.CharacterFormat.FontName = "Times New Roman";
textRange.CharacterFormat.FontSize = 14;
textRange.CharacterFormat.UnderlineStyle = UnderlineStyle.Single;
//Insert the paragraph as the third paragraph
section.Paragraphs.Insert(2, para);
//Set spacing after the paragraph
para.Format.AfterSpacing = 10;
//Save the result file
doc.SaveToFile("InsertParagraph.docx", FileFormat.Docx2016);
}
}
}
