Event Recurrence like Outlook ~ Sample DB design

Hi

i am creating custom form for creating new Event( of Event List). How can i include reccurence event UI and functionlaity in my custom  form?

 

Thanks and Regards,

Provide an interface for creating families of related or dependent objects without specifying their concrete classes

Specify the kind of objects to create using a prototypical instance, and create new objects by copying this prototype

Convert the interface of a class into another interface clients expect. Adapter lets classes work together that couldn't otherwise because of incompatible interfaces.

Ensure a class has only one instance and provide a global point of access to it.

design pattern can solve many problems by providing a framework for building an application. Design patterns, which make the design process cleaner and more efficient, are especially well-suited for use in C# development because it is an object-oriented language. Existing design patterns make good templates for your objects, allowing you to build software faster. This article describes several popular design patterns you can use in your own applications, including the singleton, the decorator, the composite, and the state classes, which can improve the extensibility of your applications and the reuse of your objects.

Software professionals may be familiar with the term "Design Patterns," but many have no idea of where they come from and what they truly are. Consequently, some do not see the value and benefits design patterns bring to the software development process, especially in the areas of maintenance and code reuse.

It is not the intent of the Design Pattern Series to focus on providing a theoretical knowledge dump of all there is to know about design patterns. There are many books that do that already. Instead, this series will focus on providing lots of practical examples. However, there will be some theory to help address important points concerning design patterns. I use the theory of design patterns mostly as a guide and instead make references to good design pattern books for more detail explanation.

When we want to make a only one instance of a class and also making sure that there is a global access point to that object then the design pattern we user is called Singleton. The pattern ensures that the class is instantiated only once and that all requests are directed to that one and only object.

Software architects generally think in terms of high-level abstractions rather than low-level programming details. Representing a system in terms of high-level abstractions promotes understanding of the system and reduces its perceived complexity. One such set of abstractions is software design patterns. They have been successfully applied in the past to simplify and solve recurring problems in software design.

The GOF design patterns help address the following challenges :

design ready to accommodate change & growth

design flexible systems which come ready to handle reconfiguration and run time tailoring

code in manner to facilitate reuse during the development and extension phases ... ie. both external and internal reuse, so that we are rewarded by efficiencies as the project progresses, coming from investments made earlier in the project.

implement change in a way that doesn't overly shorten the system's useful lifespan

What is the State Pattern?

The State Pattern is a behavioral pattern that can be used to alter the behavior of an object at run time. As the state of an object changes, the functionality of the object can change drastically. This change of behavior is hidden from the Client and the Client interfaces with a wrapper object known as the Context. The State Pattern is a dynamic version of the Strategy Pattern.

Here I have explained the events of radio button with javascript.
Let me explain the scenarion first,
We are having two radio button say radioobtn1 and radiobtn2. If I click on the button 1 then I need to show one DIVor FORM. same as when I click on radiobtn 2. I have given the code for the above scenarion.

We have a Windows 2003 server running IIS6 1.1 Framework. We have also installed a DNS and Active Directory in the same machine.

We're randomly getting the error you can see below. Sometimes it causes the recycling of process w3wp.exe (which on my understanding represents the application pool worker processd) and other times results on this process hanging and not responding to any request. To do iisrest temporarly solves the problem.

We were pointed to a possible permissions problem between the user we were runnig the DefaultAppPool with and registry entries used by the iis. We noticed the default predifined user we used, Network Service, wasn't found in the Active Directory, so we changed it by the default configurable user, IWAM_MACHINE_NAME, which is under the IIS_WPG Active Directory Grupo, which, in theory has the correct permissions to run the application pool.

Well, none of this worked and we are still getting this error.

This is driving us crazy and think the problem might have to do with having the Domain Controller/Active Directory and the IIS6 running on the same machine. We'll try now uninstalling this DC pointing to another one to see what happens.

Any help would be appreciated.

Thanks in advance,

Gabriel.
