C# Learning: interface and abstract class


Interface names start with I Whenever you create an interface, you should make its name start with an uppercase I. There’s no rule that says you need to do it, but it makes your code a lot easier to understand. You can see for yourself just how much easier that can make your life. Just go into the IDE to any blank line inside any method
and type “I”—IntelliSense shows .NET interfaces.


interface IStingPatrol
{
int AlertLevel { get;}
int StingerLength { get; set;}
bool LookForEnemies();
int SharpenStinger(int length);
}


When you mark a class abstract, C# won’t let you write
code to instantiate it. It’s a lot like an interface—it acts like a
template for the classes that inherit from it.
abstract class abc{}

Stretch a row if data overflows in jasper reports

It is very common that some columns of the report need to stretch to show all the content in that column. But  if you just specify the property " stretch with overflow' to that column(we called text field in jasper report world) , it will just stretch that column and won't change other columns, so the row could be ridiculous. Haven't find the solution from internet yet. So I just review the properties in iReport one by one and find two useful properties(the bold  highlighted in example below) which resolve the problems.   example: <band height="20" splitType="Stretch" > <textField isStretchWithOverflow="true" pa...

Live - solving the jasper report out of memory and high cpu usage problems

I still can not find the solution. So I summary all the things and tell my boss about it. If any one knows the solution, please let me know. Symptom: 1.        The JVM became Out of memory when creating big consumption report 2.        Those JRTemplateElement-instances is still there occupied even if I logged out the system Reason:         1. There is a large number of JRTemplateElement-instances cached in the memory 2.     The clearobjects() method in ReportThread class has not been triggered when logging out Action I tried:      About the Virtualizer: 1.     Replacing the JRSwapFileVirtualizer with JRFileVirtualizer 2.     Not use any FileVirtualizer for c...
