2. Create a new VB.NET project and Install IronPDF

Before we start writing the code we need to create a new Visual Studio project and install the IronPDF library to convert HTML to PDF using the VB programming language.

Create a New VB.NET Project:

Open Visual Studio and follow these steps to create a new VB.NET project:

Click on "File" > "New" > "Project..."

Choose a project template based on your application type (e.g., Windows Forms, Console Application, ASP.NET, etc.) and click on Next.

Enter a name and location for your project and click on the Next button.

Select the target framework and Click "Create" to create the project.

Install IronPDF:

After creating the project, you'll need to install the IronPDF library using NuGet. Here's how:

Right-click on your project in the Solution Explorer.

Select "Manage NuGet Packages..."

In the "NuGet Package Manager" window, make sure "Browse" is selected on the left.

In the search box, type "IronPDF".

Select the "IronPDF" package from the search results.

Click the "Install" button to install the package.

3. Convert HTML to PDF Document using IronPDF and VB Programming Language

The process of generating PDFs from HTML content and files is both intriguing and conveniently achievable with the utilization of IronPDF. In the forthcoming sections, we will delve into illustrative examples that demonstrate the seamless conversion of both HTML strings and HTML files into meticulously crafted PDF documents.

3.1. HTML String to PDF document

IronPDF provides the feature to convert HTML to PDF documents using VB programming language with just a few lines of code. Let's see how this works in the below sample code snippet.

Imports IronPdf
Module Module1
    Sub Main()
        Dim renderer = New IronPdf.HtmlToPdf()
        Dim document = renderer.RenderHtmlAsPdf("<h1> My First PDF in VB.NET</h1>")
        document.SaveAs("MyFirst.pdf")
    End Sub
End Module

Imports IronPdf
Module Module1
    Sub Main()
        Dim renderer = New IronPdf.HtmlToPdf()
        Dim document = renderer.RenderHtmlAsPdf("<h1> My First PDF in VB.NET</h1>")
        document.SaveAs("MyFirst.pdf")
    End Sub
End Module

This sample code snippet first imports the IronPDF namespace, which contains the classes and methods that are used to work with PDF documents. Then, it creates a new rendering engine object, which is used to convert HTML to PDF. The RenderHtmlAsPdf() method of the renderer object takes an HTML string as its input and returns a Document object that represents the PDF document. Finally, the SaveAs() method of the Document object is used to save the PDF new document to a file.

3.2. HTML File To PDF Document

In the following section, we will explore the process of converting an HTML page into a PDF format using the IronPDF library. To begin, you can either generate a new HTML file by writing HTML code or utilize an existing one as your starting point.

3.2.1. HTML Input File

Imports IronPdf
Module Module1
    Sub Main()
        Dim renderer = New ChromePdfRenderer()
        Dim document = renderer.RenderHtmlFileAsPdf("invoice.html")
        document.SaveAs("invoice.pdf")
    End Sub
End Module

Imports IronPdf
Module Module1
    Sub Main()
        Dim renderer = New ChromePdfRenderer()
        Dim document = renderer.RenderHtmlFileAsPdf("invoice.html")
        document.SaveAs("invoice.pdf")
    End Sub
End Module

The above source code first creates an HTML form renderer object using the "ChromePdfRenderer" method, then converts the HTML file to PDF using the "renderer.RenderHtmlFileAsPdf" method. In the end, save the PDF file using the "SaveAs" method.
