Reporting and external images
-
Hi all... I'm working on a report (Reporting Services) with an external image. The problem is it's not showing up. I'm passing the image through as a base64 string to the report and converting it back to bytes using the Convert.FromBase64String function. The code is as follows
Dim location As String = Configuration.ConfigurationSettings.AppSettings("location")
Dim reader1 As New System.IO.StreamReader(location)
Dim base64 As String
Dim BinRead As New BinaryReader(reader1.BaseStream)
Dim file1 As New FileInfo(location)
base64 = Convert.ToBase64String(BinRead.ReadBytes(CType(file1.Length, Integer)))
Dim param As New Microsoft.Reporting.WinForms.ReportParameter("Image", base64, False)
Dim al As New List(Of Microsoft.Reporting.WinForms.ReportParameter)
al.Add(param)
ReportViewer1.LocalReport.EnableExternalImages = True
ReportViewer1.LocalReport.SetParameters(al)
ReportViewer1.RefreshReport()
.
.
.Please ignore the BinReader / Reader bit. I havn't fixed that up yet. If someone can please tell me why this thing is not showing an image. I would be very greatful.
