Crystal Delivery 8.0.0.2 'Value cannot be null' Error
I have tried to search the forum without any results. I have also tried to find an older verion of the program to test before submitting to the forum, but again was out of luck. I really hope you can help. I have been using CD 8.0.0.1 with success for various reports, all created using Crystal v9. However I have some new reports which fail every time. I have now upgraded to CD 8.0.0.2 hoping to overcome this error. The error I have is: Value cannot be null. Parameter name: fileName I schedule the report, complete each tab, there are no parameters. The command line looks like: "C:\Program Files\Groff Automation\Crystal Delivery\CrystalCMD.exe" "SOURCEREPORT" "O:\GoldMine\Reports\Daily Figures\Order Intake Report.rpt" "CONNECTION" "MIAD" "MIAD" "TIe7ehNTfGgh01xld3txrg==" "TIe7ehNTfGgh01xld3txrg==" "EXPORTDIRECTORY" "D:\Crystal Delivery Reports\Order Intake Report.pdf" The report is scheduled to run every 1 Days, Mon-Fri I have an ODBC Source setup up to the SQL server which is the source data for the report. This is tested and working fine. I am able to View the report within Crystal Delivery and the report outputs correctly with current data. At this stage the system is in Manual Mode and once the report is scheduled, I am clicking the Export button to force an export which generates the error. I get the same results if the system is in Auto Mode. The debugging info is: See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. ************** Exception Text ************** System.ArgumentNullException: Value cannot be null.

I have tried to turn off the Email File option under Export Directory and then click Export and it seems to complete, I don't get any errors, a blank email is sent to me, but no PDF file is created. There's no PDF file created in either instance. I have also tried different output formats and non work - giving the same results. I have also tried different output folders on the local drive. Fingers crossed you can help. I will install an older version if that would fix the problem.

I am having a similar problem. It works for the first time logged in. Then it locks the file and brings up this error on the second running.

solution
I have got a solution - th file locks so - give the file a new anme everytime. Do this by putting <#> in the filename.

I have been suffering this problem since version 8.0.0.1 and was hoping for a fix in 8.0.0.2. Reading the posts above, I was able to work out that two of my report entries were set to use the same export file name and were configured to run at similar times. This will obviously create a file lock issue when the first report runs and generates the export file followed by the second report trying to open the same file in read/write mode. The locked file is enough to crash the program and spit the misleading "filename cannot be null" message. So, I have now given each report a unique export file name and will know tommorow whether this has cured the issue as it is always on Tuesday that this happens for me. Looking back to the original post, if you look at the file path for the export file, it appears to be missing a backslash after D: Also, I always use underscores to separate names within filenames as not all software supports spaces within filenames.
