How to add QR code to word using C#, VB.NET.docx
Syncfusion® Essential® DocIO is a .NET Word library used to create, read, and edit Word documents programmatically without Microsoft Word or interop dependencies.
Using this library, you can add a QR code to a Word document in C# and VB.NET. Below steps should be followed:
- Design your template Word document with the required layout and merge fields using Microsoft Word
- Using Syncfusion PDF library you can generate a QR code.
- Insert the generated QR code as an image into the Word document with MergeImageField event using Essential® DocIO.
Steps to add a QR code to a Word document using C# and VB.NET:
- Create a new C# console application project.
- Install the Syncfusion.DocIO.WinForms NuGet package as a reference to your .NET Framework applications from the NuGet.org.
- Include the following namespaces in the Program.cs file.
C#
using Syncfusion.DocIO; using Syncfusion.DocIO.DLS; using Syncfusion.Pdf.Barcode; using Syncfusion.Pdf.Graphics;
VB
Imports Syncfusion.DocIO Imports Syncfusion.DocIO.DLS Imports Syncfusion.Pdf.Barcode Imports Syncfusion.Pdf.Graphics
- Use the following code to add a QR code to a Word document.
C#
// Open an existing document.
using (WordDocument document = new WordDocument(Path.GetFullPath(@"../../Template.docx"), FormatType.Automatic))
{
// Create mail merge events handler for image fields
document.MailMerge.MergeImageField += new MergeImageFieldEventHandler(InsertQRBarcode);
// Get data to perform mail merge
DataTable table = GetDataTable();
// Perform the mail merge
document.MailMerge.ExecuteGroup(table);
// Save and close the Word document instance
document.Save("Result.docx", FormatType.Docx);
}
System.Diagnostics.Process.Start("Result.docx");
VB
' Open an existing document.
Using document As WordDocument = New WordDocument(Path.GetFullPath("../../Template.docx"), Syncfusion.DocIO.FormatType.Automatic)
' Create mail merge events handler for image fields
AddHandler document.MailMerge.MergeImageField, AddressOf InsertQRBarcode
Dim table As DataTable = GetDataTable()
' Perform the mail merge
document.MailMerge.ExecuteGroup(table)
' Save and close the Word document instance
document.Save("Result.docx", Syncfusion.DocIO.FormatType.Docx)
End Using
System.Diagnostics.Process.Start("Result.docx")
- Include the following helper method to insert QR code image using MergeImageField event.
C#
private static void InsertQRBarcode(object sender, MergeImageFieldEventArgs args)
{
WParagraph paragraph = new WParagraph(args.Document);
if (args.FieldName == "QRBarcode")
{
// Generate barcode image for field value.
Image barcodeImage = GenerateQRBarcodeImage(args.FieldValue.ToString());
// Set barcode image for merge field
args.Image = barcodeImage;
}
}
VB
Private Sub InsertQRBarcode(ByVal sender As Object, ByVal args As MergeImageFieldEventArgs)
Dim paragraph As WParagraph = New WParagraph(args.Document)
If (args.FieldName = "QRBarcode") Then
' Generate barcode image for field value.
Dim barcodeImage As Image = GenerateQRBarcodeImage(args.FieldValue.ToString)
' Set barcode image for merge field
args.Image = barcodeImage
End If
End Sub
- Include the following helper method to generate a QR code image using the Syncfusion PDF library.
C#
private static Image GenerateQRBarcodeImage(string qrBarcodeText)
{
// Drawing QR Barcode
PdfQRBarcode barcode = new PdfQRBarcode();
// Set Error Correction Level
barcode.ErrorCorrectionLevel = PdfErrorCorrectionLevel.High;
// Set XDimension
barcode.XDimension = 3;
barcode.Text = qrBarcodeText;
// Convert the barcode to image
Image barcodeImage = barcode.ToImage(new SizeF(125.5f, 135.5f));
return barcodeImage;
}
VB
Private Function GenerateQRBarcodeImage(ByVal qrBarcodeText As String) As Image
' Drawing QR Barcode
Dim barcode As PdfQRBarcode = New PdfQRBarcode
' Set Error Correction Level
barcode.ErrorCorrectionLevel = PdfErrorCorrectionLevel.High
' Set XDimension
barcode.XDimension = 3
barcode.Text = qrBarcodeText
' Convert the barcode to image
Dim barcodeImage As Image = barcode.ToImage(New SizeF(125.5F, 135.5F))
Return barcodeImage
End Function
- Include the following helper method to get data for Mail merge execution process.
C#
private static DataTable GetDataTable()
{
// List of product names.
string[] products = { "Apple Juice", "Grape Juice", "Hot Soup", "Tender Coconut", "Vennila", "Strawberry", "Cherry", "Cone",
