Difference between abstract class and interface
Answer Posted / niraj kumar
)We define an Interface in the Java application with a
set of abstract methods without any implementation. Which
means all the methods of an interface are by default
abstract methods and public methods.
2)Once an Interface is defined in the application then any
class can implement that interface, in such case the class
must be implemented with all the mehtods of the respective
Interface otherwise the class will become as abstract class.
3)A class can implement any no. of interfaces, in such case
the class must be implimented with all the methods of those
interfaces otherwise the class will become as abstract class

I am working with asp.net 2005 and Crystal report 10. I have an image field on my dataset to show on Crystal report.And the image is shows dynamically from database in image field of CR. The image field is showing well on my Crystal report on its first page with all other data but when i click to open second page of CR,it does not show any data on that.I found that this is because of adding the image field on crystal report. Because when i remove the image field from the CR then it will run both the pages of CR. I am using the Page Load event to bind CR data with Database. And i have already check with the Init event to bind CR , but it still not shows the data on second page when i use image field on that. Please give solution for that.....
