  • Visual Studio 2010

Reproducing the Issue

  1. Using Crystal Reports for Visual Studio 2010 (CRVS2010)
  2. Use the code as described below
  3. Compile application as 64 bit or "Any CPU"
  4. Deploy the application using CRVS2010 64 bit runtime to a 64 bit Operating System with 64 bit Microsoft Outlook 64 bit installed
  5. Code:

private void Export_Click(object sender, EventArgs e)
CrystalDecisions.Shared.MicrosoftMailDestinationOptions mailOpts = CrystalDecisions.Shared.ExportOptions.CreateMicrosoftMailDestinationOptions();
CrystalDecisions.Shared.DiskFileDestinationOptions diskOpts = CrystalDecisions.Shared.ExportOptions.CreateDiskFileDestinationOptions();
CrystalDecisions.Shared.ExportOptions exportOpts = new CrystalDecisions.Shared.ExportOptions();
CrystalDecisions.Shared.PdfFormatOptions PDFExpOpts = new CrystalDecisions.Shared.PdfFormatOptions();
rpt.Load(@"c:\reports\World Sales Report.rpt");
PDFExpOpts.CreateBookmarksFromGroupTree = true;
PDFExpOpts.FirstPageNumber = 1;
PDFExpOpts.LastPageNumber = 1;
PDFExpOpts.UsePageRange = true;
// this gets the report name and sets the export name to be the same less the extension
string MyRptName = rpt.FileName.ToString();
MyRptName = MyRptName.Substring(MyRptName.LastIndexOf(@"\") + 1, (rpt.FileName.Length - 3) - (MyRptName.LastIndexOf(@"\") + 1)) + "pdf";
diskOpts.DiskFileName = MyRptName;
mailOpts.MailMessage = "See attached Action Plan";
mailOpts.MailSubject = "Action Plan";
mailOpts.MailToList = "";
mailOpts.Password = "YourMSNPassword";
exportOpts.ExportDestinationOptions = mailOpts;
exportOpts.ExportDestinationType = CrystalDecisions.Shared.ExportDestinationType.MicrosoftMail;
exportOpts.ExportFormatOptions = PDFExpOpts;
exportOpts.ExportFormatType = CrystalDecisions.Shared.ExportFormatType.PortableDocFormat;
