Please tell me where is the problem.

Dim builder As New Aspose.Words.DocumentBuilder(m_document)

Dim objsection As Aspose.Words.Section


builder.Font.Name = PrpFontName

builder.Font.NameBi = PrpFontName

builder.Font.Size = PrpFontSize

builder.Font.SizeBi = PrpFontSize

If PrpFontStyle = "Bold" Then

builder.Font.Bold = True

builder.Font.Italic = False

ElseIf PrpFontStyle = "Italic" Then

builder.Font.Italic = True

builder.Font.Bold = False

End If


Hi<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Thanks for your inquiry. It is not enough to change font of whole section. If you need to change font of whole section then you should change font of each node in this section. For example see the following code:

Dim doc As Document = New Document("in.doc")

'Get collection of Runs

Dim nodes As NodeCollection = doc.Sections(1).GetChildNodes(NodeType.Run, True)

'Change font of aech run in the section

For Each currentRun As Run In nodes

currentRun.Font.Size = 14

currentRun.Font.Bold = True


'Change font of each formfield in the section

For Each field As FormField In doc.Sections(1).Range.FormFields

field.Font.Size = 14

field.Font.Bold = True



Hope this helps.

Best regards.

I have used this code to change the font of the document as well, however I have noticed that spurious font information is left behind immediately following any fields in the source document. Here is my sample code.

using System;
using System.Collections.Generic;
using System.Text;
using Aspose.Words;
using Aspose.Words.Fields;

namespace ConsoleApplication1
public class AsposeHandler
public void DoStuff()
Document sourceDoc = new Document(“c:\TestFolder\TestDoc.doc”);
NodeCollection runs = sourceDoc.GetChildNodes(NodeType.Run, true);
foreach (Run run in runs)
run.Font.Name = “Arial”;
run.Font.Size = 12;

foreach (Section section in sourceDoc.Sections)
foreach (FormField field in section.Range.FormFields)
field.Font.Name = “Arial”;
field.Font.Size = 12;


class Program
static void Main(string[] args)
AsposeHandler handler = new AsposeHandler();

The original document (TestDoc.doc) is in the Lucida font, I run this code over it to produce the output document (TestOutput.doc), changing all font information in the process, however if i use the cursor keys to move through the document I note that after every field there is still Lucida font information left behind. This would not normally be much of an issue but we then do something extra to those fields which then changes the font of the field back to Lucida. I have attached both the source document and the output document for you to have a look at.

(We use version of Aspose.Words)

Hi<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Thanks for your request. It is better to use DocumentVisitor to achieve this. Here is code:

//Open document

Document sourceDoc = new Document(@"Test123\in.doc");

// Create an object that inherits from the DocumentVisitor class.

FontChanger changer = new FontChanger("Arial");

//Get the model to accept a visitor.

// The model will iterate through itself by calling the corresponding methods

// on the visitor object (this is called visiting).


//Save output document


FontChanger class is attached.

Best regards.

Thanks for that, works a treat!

Okay, but is it also possible to find and replace (for example) all text with font "Arial size 10" by "Times New Roman size 12"?

No matter if the text is in a textbox, header or footer?

Do you have an example of this?

Thanks for your request. Of course, you can achieve this. Here you can find another version of FontChanger class, which allows also changing font size:


In FontChanger, you can also check the font of the original node.

Hope this helps. Please let me know if you need more assistance, I will be glad to help you.

Best regards.
