ASP.NET – Code Snippets and Tutorials

May this Christmas be bright and cheerful and may the New Year begin on a prosperous note! To all ASP.NET developers and their families! Cheers!!!

Hello Guys,

Recently i had very bad experience begging a bloody company for my own money.
Finally i want to tell you to stay away from this company and their site www.getafreelancer.com.
You should always deal with people whose addresses are real, customer service real and you can get a live person on the phone.
Yeah, that’s true that GAF has not phone number to be called. It sucks, isn’t it?
They have a LIVE SUPPORT button on their site but all it does is take you to their email form so their support is not live particularly when they take days on end to answer, if they bother to answer at all.

In addition, www.getafreelancer.com is in the habit of suspending members when their accounts have money in them. This has recently happened to me and I am aware of others that have gone through the same problem. In addition to this they will ask for ID of proof of Country. When you provide them with the pertinent information where they can see the ID. clearly but not to the point where it can be duplicated they want more. This doesn’t make any sense if its just for proof of country.
This is obviously something that this Company has been getting away with for some time. They are holding money not only in peoples personal accounts of money they have earned, but also in escrow.
Its time people took legal action. You can start by laying a complaint with the internet crime complaint center. There are also other legal sites listed on the internet as well that you can lodge a complaint with.

Strongly recommended!

I’ve read many different suggestions for the Invalid postback or callback argument exception but, most of them do not work.
Some people will suggest to add your code inside If Not Page.IsPostBack Then block, other will tell you to set EnableEventValidation to false which is not serious at all. Even the compiler suggests ClientScriptManager.RegisterForEventValidation method but in most of the situations these will not work.

One is for certain: This specific exception is mostly thrown when you use a Master page!!!

Add the same javascript attributes to the very same server control out of the master page and you’ll see that it is working just fine.

This is going to be pretty easy so i will not bother you explaining things.
Just Download the Code Sample (sample images included) and you will figure out the rest of it, analyzing the code.
Generally speaking, it gets all *.jpg images from the given folder and display in the DataList control.

Live Example For Binding DataList Without Database (List of Images)

The Source Code Can be Downloaded From Here

Sometimes we want to provide encryption and secure identification of the server creating a secure channel over an insecure network.
In that case we need HTTPS connection which ensures reasonable protection e.g. for payment transactions.

 

Ok let’s see how this thing works.

Say that your page is as follows: http://www.domain.com/yourpage.aspx
Ok, just add this code inside Load Event Handler and voila! That’s it!

 

If Not Request.IsSecureConnection Then
   Response.Redirect("https://www.domain.com/yourpage.aspx ")
End If

 

I just ran my MSN Live Messenger and i was offered to download a free themes for its 10th Birthday.

Ok althrough i never believed in a free stuff this time i said what a hell.

As soon as i clicked the Download button i was offered to download Internet Explorer 8 and immediately after that i received another dialog which was suggesting me to use Bing as my default browser and to make MSN my homepage.

I mean it’s a pretty bad trade. I get only few themes that most probably i will never use and in return they want me to to use IE8 (instead firefox), Bing (instead google) and to make MSN my homepage (instead google as well).

Well thanks for the generous offer but, i really don’t need your FREE things.

Although this is a very basic example (Hello World) of Web Service,  it should be enough to get an idea about how it works.

A picture is worth a thousand words!

Please send your comments if my WebService video tutorial is sort of blurred or something. Thanks

This is where i am drinking my first cup of morning coffee. It is a coffee bar located near me. Just 100 m from my apartment.

Btw, i do not smoke. It is the guy behind me!

As you know Google announced a new OS called Chrome which is primarily intended and targeted for the netbooks.

However, i want to notice that if Google doesn’t find a way to run ALL (literally all) windows software applications on the new operating system it is going to be just one more Linux distribution.

If the new Chrome OS is able to run MS Office, Visual Studio and SQL Server it will become a serious competition to the Windows. Otherwise as mentioned it will end up as one more Linux distro.

1. I hate VB.NET because it doesn’t support block comments. Block comments are very useful for comment out large sections of code. Even T-SQL support block comments! It’s so sad and i need it on daily basis when i am testing something and large section of code should be commented out. I have to use Comment Selection Ctrl+c, Ctrl+k instead.

To be continued…

This is a very basic example to show that binding ListView is really easy.
For this tutorial i created a new table named Members:

Hi Ronan,

this should help you i hope.

Anyway, it shouldn’t be anything complicated so we could start with the code immediately.

Congratulations Roger! Keep up the good work

It was a very enjoyable match and I’m truly impressed with Andy Roddick.

He played the best match I’ve ever seen him play today.

Big Thanks to both of you guys!

Today is Independence Day also known as 4th of July which is the birthday of the United States of America.

On this day, people of United States celebrate their freedom commemorating the courage and faith of their founding fathers in their pursuit of liberty.

So happy Fourth of July to all  American ASP.NET and VB.NET developers including all My Friends in USA !!!

I refuse to believe that Madoff is the one and only who is responsible for the new world economic crisis.

Of course he has to fully take responsibility for what he has done but, sentencing only one man to 150 years is NOT a guarantee that it will not happen again?

Rather, we should find out, who endorsed Madoff … ?

I am aware that American justice works in strange ways but, this is too much already.

I am quite sure there must be some people that knew all the time about the Madoff’s tricks and that he was braking the law but none wanted to tell anything because they were probably all involved in.

Otherwise i have no explanation for it !!!

While the rest of the world is enjoying the era of Nanotechnology, Macedonia (Republic of) is living far behind the expansion of modern science and technology.
So, we cannot move forward because:

1. Our students are still studying Pascal and Java although the IT market demands technologies like ASP.NET, PHP, T-SQL, VB.NET, C# and such. As Macedonian University Professors do not want to upgrade their knowledge our students will stay “not competitive“, “not goal oriented,” and “not future-directed“. Period.

2. Macedonian companies are used to old fashion marketing using medias like Newspapers, Radio and TV. They do not pay attention to the internet marketing which is totally wrong. We need campaigns to constrain these companies to use the potential of the internet. This will cause more people to learn internet marketing, graphic design, program languages and technologies that would affect the unemployment additionally.

3. People in Macedonia use internet only for fun. Mainly they are focused on social networks like facebook and myspace, and also on several domestic portals. They are not aware that the internet is serious business tool/medium that deserves consideration in many, if not all, fields of commerce and it can offer remarkable advantages and opportunities to all of us. Someone needs to motivate and teach them to earn money on the internet.

I registered a few domains at godaddy a while back and also i bought new hosting plan from the same company.

The interesting thing is that prior to Checkout i reminded myself of the suggestion of my friend who actually told me about godaddy coupons.

I thought it is not big deal so i was always ignoring his appeals. lol

Well, this time i decided to follow his advice so i opened his email with the newest godaddy coupons.

As soon as i entered BTPS7 the grand total was drastically decreased by whole 20%.

Wow … i just saved about $40 which is not a low amount at all. I could buy some extra domains with this money. And i did so. I spent that money buying 6 extra domains. So cool!!!

From now i will always use the promo codes when i shop online!

So, here’s a list of a few codes for 2009

There are numerous techniques that allow a program to be launched automatically by Windows at startup but, let’s see if we can achieve that programatically using VB.NET.

You can automatically start programs whenever Windows launches modifying the registry.

First of, don’t forget to import the Microsoft.Win32 namespace

You must be wondering why i am writing about Wordpress and what it has to do with ASP.NET.

Ok i must say that i really love this platform and it is probably the only and the best open-source thing i have ever used in my life. Beside MySQL of course!

As my blog is built on Wordpress platform it is understandable that  i am concerned if it works efficiently. right?

Well then let me tell you something about that.

I have been very frustrated when i noticed that my blog is suffering from the so called slow motion. My blog readers was complaining that the blog is getting too slow and that connect time is high. Actually there was a one or two second delay when the page is loading (after it connects and before any graphic comes up).

I was asked some time ago to develop an application which involved sending multiple email messages. Later i realized that it is known as mass mail sender.

Means, if you launch an email marketing campaign sending a targeted newsletters and advertisements, you need a mass/bulk sender for that.

Although i have never used any, in fact i know how they work.  Hey – you’re talking to the email king here. I am just kidding … let’s move on!
