copied from .Net-forum *** Hello we have one strange problem on one client where we use crystal reports.We have one application written in C# in VS2005 where we use some reports to that embed graphics generated from ZedGraph.The application works very fine on all clients except one.The
report is prety simple. There are only 3 image items on the detail
section and we pass the image data as a byte[] array to the report
inside our dataset. For every image on the report we get the following
error:"Crysytal Report Windows Forms Viewer"-"Der Wert darf nicht NULL sein.Parametername:path1"Which means "The value must not be NULL. Parametername: path1" We get the same errormessage for every image on the report.We
allready checked the data inside the dataset and it is filled of course
(also the same report works with the same data on other clients).Also other reports work fine on that client. Olny the once where image-data is passed from code is not working.  Here is some additional data:OS: Windows XP ProfessionalCR-Files from: CrystalReportsRedist2005_x86.msm (27. Januar 2006)Language  C# VS2005 Setup-Type: Install-Shield 12 (CR via merge-module) Here is some democode that produces the error (sorry i don't have permission to upload the project...)            ZedGraph.ZedGraphControl zgc = new ZedGraphControl();            zgc.Size = new Size(950, 500);            CreateChart(zgc);            Bitmap bmp;            MemoryStream ms;                        bmp = zgc.GraphPane.GetImage();                        ms = new MemoryStream();                        bmp.Save(ms, ImageFormat.Bmp);                        byte[] myImg = ms.GetBuffer();            ms.Close();            dsImage1.DataTable1.Rows.Add(myImg);            MessageBox.Show("Len of image in DS:" + ((byte[])dsImage1.DataTable1.Rows[0]["Img"]).Length);            rpt.SetDataSource(dsImage1);    //here comes the error            crystalReportViewer1.ReportSource = rpt; The dataset consists of oly on Img tag. Any suggestions? Thanks in advance rene.

Hi,
CL_MAPPING_XMS_PLSRV3-ENTER_PLSRV Interface Mapping http://hsbc.com
IM_PAYEXT_PEXR2002_To_PEXR2002_BPM The value for the input paramter
DIRECTORYNAME must not be null
This is your error...make sure that when the mapping IM_PAYEXT_PEXR2002_To_PEXR2002_BPM is executed the element DIRECTORYNAME is present and is always containin some value...sort of mandatory field.
Regards,
Abhishek.
