Using Package Manager Console

Run the following command in the Package Manager Console:

Install-Package IronWord

Creating a Word Document in VB.NET

Let's go through a simple example to demonstrate how to create a Word document using IronWord in VB.NET:

Imports IronWord
Imports IronWord.Models
Module Program
    Sub Main()
        ' Create a textrun
        Dim textRun As New TextRun("Sample text")
        ' Create a paragraph and add the textrun
        Dim paragraph As New Paragraph()
        paragraph.AddTextRun(textRun)
        ' Create a new Word document using the paragraph
        Dim document As New WordDocument(paragraph)
        ' Export the document as a docx file
        document.SaveAs("document.docx")
    End Sub
End Module

Imports IronWord
Imports IronWord.Models
Module Program
    Sub Main()
        ' Create a textrun
        Dim textRun As New TextRun("Sample text")
        ' Create a paragraph and add the textrun
        Dim paragraph As New Paragraph()
        paragraph.AddTextRun(textRun)
        ' Create a new Word document using the paragraph
        Dim document As New WordDocument(paragraph)
        ' Export the document as a docx file
        document.SaveAs("document.docx")
    End Sub
End Module

'INSTANT VB TODO TASK: The following line uses invalid syntax:
'@Imports IronWord @Imports IronWord.Models Module Program @Sub Main() ' Create a textrun @Dim textRun @As @New TextRun("Sample text") ' Create a paragraph @and add the textrun @Dim paragraph @As @New Paragraph() paragraph.AddTextRun(textRun) ' Create a New Word document using the paragraph @Dim document @As @New WordDocument(paragraph) ' Export the TryCast(document, a) docx file document.SaveAs("document.docx") @End @Sub @End Module

Code Explanation

Let's break down the key components of this VB.NET code for creating a Word Document:

Importing the IronWord Namespace:

Imports IronWord
Imports IronWord.Models

Imports IronWord
Imports IronWord.Models

'INSTANT VB TODO TASK: The following line uses invalid syntax:
'@Imports IronWord @Imports IronWord.Models

These lines import the necessary namespaces from the IronWord library to use the classes and Word document model in your VB.NET code.

Creating a TextRun and Paragraph:

Dim textRun As New TextRun("Sample text")
Dim paragraph As New Paragraph()
paragraph.AddTextRun(textRun)

Dim textRun As New TextRun("Sample text")
Dim paragraph As New Paragraph()
paragraph.AddTextRun(textRun)

'INSTANT VB TODO TASK: The following line uses invalid syntax:
'@Dim textRun @As @New TextRun("Sample text") @Dim paragraph @As @New Paragraph() paragraph.AddTextRun(textRun)

Here, a TextRun is created with the content "Sample text," and a Paragraph is created to hold the TextRun. This sets up the template document with the content structure of the Word document.

Creating a Word Document:

The following code creates a new document object and adds a text paragraph to it:

Dim document As New WordDocument(paragraph)

Dim document As New WordDocument(paragraph)

'INSTANT VB TODO TASK: The following line uses invalid syntax:
'@Dim document @As @New WordDocument(paragraph)

An instance of the WordDocument class is created, and the Paragraph is passed to its constructor. This initializes the Word document with the specified content.

Exporting the Document:

document.SaveAs("document.docx")

document.SaveAs("document.docx")

'INSTANT VB TODO TASK: The following line uses invalid syntax:
'document.SaveAs("document.docx")

Finally, the SaveAs method is used to export the Word document as a DOCX file with the filename "document.docx."

Output:

Upon running the program, a Word File named "output.docx" will be generated in the project directory. Open this document to view the added content.
