Missing parameter value Printed From: Crystal Reports Book Category: Crystal Reports .NET 2003 Forum Name: Data Connectivity Forum Discription: How to connect to data sources and export reports URL: http://www.crystalreportsbook.com/forum/forum_posts.asp?TID=4505 Printed Date: 03 Apr 2025 at 8:44am Topic: Missing parameter value Posted By: Rashi2008 Subject: Missing parameter value Date Posted: 10 Oct 2008 at 5:42am Hello , As my subject line is similar to many other threads, but i have found no help from all those threads. I have a working application in VS 2003 with SQL server. The application reads the parameters from the .aspx page and then generates the report and exports the report to specific format like PDF, EXCEL.. The application works fine. Now we want the same to be done from a Windows Services application. I have written the same code working on the Web Application in the service but the service does not produce the desired result. It gives "System.Runtime.InteropServices.COMException: Missing parameter values" exception for some reports while other reports exported very well. Can anybody help me in this? Also i was using CR 9 bundled with VS 2003, but now i have installed 8.5 and upgrade CR 10 for that. Thanks in advance. -Rashmi
