Once that is done, we need to add a reference to it by clicking Project->Add Reference->iTextSharp.dll. Mine looks like Figure 1 :īefore we can jump in and code, you need to make sure that you have downloaded the iTextSharp libraries. All we need is a progress bar and a button. Our project doesn’t have much of a design. Sound easy enough, yes, with the help of the iTextSharp library you will see how simple it is. Our project’s aim is to read from a PDF file, change some of the contents and then add a watermark to the PDF document’s pages. I cannot do everything for you, you need to have some input as well. I would suggest that you go through the documentation properly before proceeding with our project. As you can see, iTextSharp is mostly for C# and Java hence this Visual Basic.NET article. iTextSharpĪ detailed explanation, and download of iTextSharp can be found here. PDF filesĪ detailed explanation of PDF files can be found here. With this article I will demonstrate how to use iTextSharp with VB.NET to manipulate PDF files. From the moment I started using it, I fell in love with it. VB.NET unfortunately doesn’t have a built in PDF file reader object, so I had to make use of a third party’s product called iTextSharp. When you run this program you will get the PDF file (crystalExport.Recently, I had to make a VB.NET program that reads PDF file contents and replace it with customized text. So give the full path name of report here. The Crystal Report is in your project location, there you can see CrystalReport1.rpt. FormatOptions = CrFormatTypeOptions End With cryRpt.Export() Catch ex As Exception MsgBox(ex.ToString) End Try End SubEnd ClassĬryRpt.Load("PUT CRYSTAL REPORT PATH HERE\CrystalReport1.rpt") DestinationOptions = CrDiskFileDestinationOptions. ExportFormatType = ExportFormatType.PortableDocFormat. ExportDestinationType = ExportDestinationType.DiskFile. Imports CrystalDecisions.SharedPublic Class Form1 Dim cryRpt As New ReportDocument Private Sub Button1_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles Button1.Click cryRpt.Load("PUT CRYSTAL REPORT PATH HERE\CrystalReport1.rpt") CrystalReportViewer1.ReportSource = cryRpt CrystalReportViewer1.Refresh() End Sub Private Sub Button2_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles Button2.Click Try Dim CrExportOptions As ExportOptions Dim CrDiskFileDestinationOptions As New _ DiskFileDestinationOptions() Dim CrFormatTypeOptions As New PdfRtfWordFormatOptions() CrDiskFileDestinationOptions.DiskFileName = _ "c:\crystalExport.pdf" CrExportOptions = cryRpt.ExportOptions With CrExportOptions. Put the following source code in the button click events Select Form's source code view and import the following : Select the default form (Form1.vb) you created in VB.NET and drag two buttons (Button1, Button2 ) and CrystalReportViewer control to your form. In the step by step Crystal Report we pull all data from Product table, here now we are exporting that data to a PDF format file. Before we start this section take a look at the step by step Crystal Report in VB.NET. In this tutorial we are using our earlier program step by step Crystal Report for pull data from database to Crystal Reports. Please take a look at the database structure before you start this tutorial - Click here to see Database Structure. In the following example you can see how to export a Crystal Reports as a PDF format file.Īll Crystal Reports programming samples in this tutorials is based on the following database (crystaldb). Also we have to set PdfRtfWordFormatOptions and ExportFormatType.PortableDocFormat. Exporting from Crystal Reports to PDF format, we are using Crystal Reportss CrExportOptions.
