Hi Omar,
Loose Coupling it isn't a pattern, but a programming best practice. You are talking about Inversion of Control and Dependency Injection topics. I suggest you to read the following article to introduce yourself in the question : http://www.codeproject.com/Articles/25733/Dependency-Injection-Pattern-Loose-Coupling

Hi,
I have asked "Which Software Patterns makes your libs/apps testable?"
here[^]
At the bottom you will find a nice short list of patterns/principles to use.
Kind Regards,

Hallo,
im a writing a quite bigger than usually project, and I am dealing with some questions considering architecture and security.
To make it short, I have a Windows server with a WCF installed, which is waiting for an outside question from a client that needs some updates.
The updates have to be created from a dll, which accesses a Database, runs sql scripts and provides a zip file in the end.
Is it ok to call the dll from a function inside the WCF? That function should then pass a string which needs the library.
Would it be better to call a programm that consequently calls the dll, thus having a separated instance between WCF Service and the library, which accesses the database?
Or maybe there is a better solution?
Thanks in advance.

How many levels of separation do you want. Your WCF should be enough separation, I would have it call the DLL (which IS another program after all). There may be some security issues around you web server and the WCF communications that you may need to address.

Some reasons for using a separate program.
- The dll is unstable and because of that it can cause an application exit.
- The dll is already encapsulated in an executable and in fact is easier to use that way or even can only be used that way.
- The dll is not structured for multi-threading and you want to use it in more than one thread.

1. Is the DLL a .NET Assembly?
2. Do you own the DLL?
Since it is a DLL, it is going to be loaded in the same process as your WCF service. If you are the author of the DLL or you trust the source, you should be able to safely use the DLL directly from the WCF service. However, if you don't own it or you're not sure of the source, then you can load the DLL in a separate AppDomain and access it from there, mind that it there will be a overhead though.

Hii
I have a doubt in web browser related to web designing.Why html image alt text doesn't work in Firefox and IE.Could you tell me the reason?

I'm sorry, but you have picked the wrong forum for this question. Please try the web development forum, and when you do, post some code to demonstrate the problem.

The "alt" tag is meant to show text when the image isn't loaded, the "title" tag is meant for a description of an image on cursor hover. IE has been doing that wrong for many years, where Firefox follows W3C standards. A properly coded webpage should have both "alt" and "title" tags. So you can use Title For that Purpose

Open Visual Studio, select the project type that you are after and then give your project a name?
You have given too little information for any serious answer

Well, it's very outrageous comment I think.
|
|
|
|
|
|
|
Requirements?
What it means?
|
|
|
|
|
|
1) Do you have the requirments or Problem statement?
2) Is the technology defined?
3) Are you well versed in the corresponding technolgy?
"Implement a project" is a very broad term, so any more details is welcome
cheers,
Super

First, You have to design architecture and algorithms.
Second, gather information of input and output and open sources and components which will will be used on your project.
Last, implement your architecture and algorithms by your hands.

Hi there,
I'm a graphic designer working in CS6. I have a low experience doing code but I would like to start learning more.
Could someone help me come up with my first practice project and provide me a few key words to search in google to get started?
I guess what I want to do is get into UX / UI front end design. I think?
I was thinking of going with an e-mail signature or maybe something for the web.
Hmm... I really don't know where to start?
Thank you

You know what subjects you are interested in, so try those keywords.

Cool thanks - Yeah - wasn't sure if that was the right terminology ... I have done some reading and seem to think those are related ( UI, UX, and Front end) - thanks for the encouragement - Ill google it up.
