I have Visual Studio 2015 professional version. I have downloaded and installed Crystal report 13.0.19.2312
When I run my ASP.NET application and try to view report it gives me below error.
Unable to cast object of type 'FileStreamDeleteOnClose' to type 'System.IO.MemoryStream
Use Google and search for this KBA:
2105311 - ExportToStream throws exception in SP 12 in Crystal Reports for Visual Studio
Not supported, use
System.IO.Stream stream = reportDocument.ExportToStream (CrystalDecisions.Shared.ExportFormatType.PortableDocFormat)
Don
Use Fiddler and/or ProcessMonitor and or Hit F12 in Browsers and see what is generating the error.
Don
Dim report As CrystalDecisions.CrystalReports.Engine.ReportDocument
Dim oStream As System.IO.MemoryStreamreport = New CrystalDecisions.CrystalReports.Engine.ReportDocument()
report.FileName = "MyReport.rpt"
report.SetDataSource(TableData)
report.PrintOptions.PaperSize = CrystalDecisions.Shared.PaperSize.PaperLetter
oStream = report.ExportToStream (CrystalDecisions.Shared.ExportFormatType.WordForWindows)
Above line generates error. This line works fine on visual studio 2013 and windows 7 pc.
