I am trying to run a crystal report from a DOS Shell command. It errors with a Crystal Reports Windows Forms Viewer message box that states
"Value cannot be null."
"Parameter name: path1"
This message box is not generated by the report viewer program.
The report is executed with a program made using a "Visual Studios 2008 Report Viewer Control" and we called the app 'RVeiwer.exe". The report works perfectly fine when it is called in cmd.exe but errors using command.com. My 16-Bit application executes this command line: "rviewer.exe daysales.rpt"
Any advice or direction will be greatly appreciated.
