Query Engine Error.

[chinhow]

I have written an application using VB.net using Windows XP. The application has several reports and they worked well on my computer. Upon installing the application on another computer, some of the reports failed to generate. One report that works access a data table directly while those that failed are accessing a dataset with SQL statements. The error message : "Query Engine Error : c:\docu~1\*************" will appear.

Each of data connections in your application is based on a connection string. When you develop your application locally the database path points to your local hard disk which is not necessarily the same on target machine. One way to overcome this problem is to map that property of connection(connectionstring) to a key in configuration file using dynamicproperties of the connection.

This is not the answer what i want, anywhere, i found the answer in the CrystalDecision web site. The solution is to copy one of the msvcp70.dll to the target machine c:\Windows\System32

below web address maybe useful for those who faced this problem.

Most of the time i faced such an error was due to malformed relationships between database tables.
