Controls Based Security in a Windows Forms Application
From Comments :
The download is just above the author bio, at the foot of the article.
would like some help on how could this idea be applied after the user logs in? meaning how would you actually disable a control for the selected role. With this application all we have done is get a list of controls, user and role, however, how would one actually apply the settings selected after the user is logged in?

ERROR NetBeans : diamond operator is not supported in -source 1.5 (use -source 7 or higher to enable diamond operator)
Using the equals() method with String and Object in Java
equals() for String compares the content, not the object itself.
10 Examples of using ArrayList in Java - Tutorial
ArrayList represents an automatic re-sizeable array and used in place of array. Since we can not modify size of an array after creating it, we prefer to use ArrayList in Java which re-size itself automatically once it gets full
How to loop ArrayList in Java - List Itrator Traversal Code Example
Which Java (32 or 64 bit) should be selected when installing Netbeans?
NetBeans 64bit Edition
the download for 64 and 32 bit versions of the IDE is the same, the difference lies in which Java Runtime Environment the install is pointed to. You have to point it to the 64 bit JRE to have it work in 64 bit
from Eclipse message saying List cannot be resolved to a type
You can press SHIFT+CTRL+O for auto importing [packages containing classes needed]

from Eclipse IDE - Tutorial
Java can be downloaded in two flavors: a JRE (Java Runtime Environment) and a JDK (Java Development Kit) version.
The Eclipse IDE contains its own Java compiler hence a JRE is sufficient for most tasks with Eclipse.
The JDK version of Java is required if you compile Java source code on the command line and for advanced development scenarios, for example, if you use automatic builds or if you develop Java web applications.
You can define in Eclipse that a project is dependent on another project. To do this select your project, right-click on it and select Properties.
Select Java Build Path and the Projects tab.
If you add a project to the build path of another project, you can use its classes in Eclipse
Manual installation of plug-ins (dropins folder):
You should not modify the content of the Eclipse plugins directory directly. If you want to install plug-ins, put them into the dropins folder. If you want to remove it, delete the JAR from this folder

Use existing workspace with newer version of Eclipse?
In theory, new versions of Eclipse should update your workspace and project files just fine. In practice, they can become corrupted. My new rule is to create a new workspace for every major version upgrade of Eclipse (maybe more often if you’re cautious). Then I copy those projects and import the copy. This ensures I have a backup plan should something go awry. You may need to reimport your project(s) if there’s a problem that won’t go away after an upgrade.
(from ECLIPSE “CANNOT BE RESOLVED TO A TYPE” ERROR)
How to find out if an installed Eclipse is 32 or 64 bit version?
Hit Ctrl+Alt+Del to open the Windows Task manager and switch to the processes tab, OR
Open eclipse.ini in the installation directory, and observe the 4th line
32-bit programs should be marked with *32
Running 32 bit applicayion on 64 bit Eclipse
Using a 32-bit JRE with a 64-bit eclipse:
Just include the 32bit JRE as an additional Java runtime in the configuration and use it for your project.
How?

What does href="#" mean?
Post #2:
This is just a ''null'' value - which means the anchor will be seen as live (and would also enable use of the "title " tag), and should produce a hand pointer on hover - but it's use will take the user back to the same page he is on. Sometimes a better option for a ''live'' link but one which goes nowhere is -

With most browsers if you don't specify a value following it defaults to the top of the page.
