IE9 and console.log problems

2013-05-17T15:19:00.001+03:00

Hello everyone,

I have found that Internet Explorer 9 has some problems when you want to use console.log in your sites.
If you have for example:

Code:

console.log('www.extremedev.blogspot.com');

then in IE9 without the Developer Tools open it will throw an exception (but you will not be able to see it because the Developer tools is not opened).
This happens because IE does not find the console object.

There is a small fix for this - you have to

Visual Studio 2012

2012-12-06T19:32:00.000+02:00

Hello,

Well, as everybody know Microsoft Visual Studio is an integrated development environment (IDE) from Microsoft.

I've started from using the Visual Studio 2003, this was many years ago and at that time it seemed amazing. But the technologies are developing very fast and we have to keep the pace together with it, by at least having the latest IDE.

At a first look at any new IDE it is hard to use it, and as I noticed - especially for Senior Developers with more than 5 years of experience. They seem very hard to be convince to use a new technology, application and IDE.

HTML5: audio tag

2012-11-13T19:21:00.003+02:00

Hello everybody,

We will discuss about the audio tag in this post.
This tag is available in HTML 5.
You can play an audio file right in browser, and you can do that without using flash.

A note that I did not find anywhere is that not all browsers support mp3 files and not all browsers support wav files. This is why you need to have both mp3 and wav files.

So a cross browser solution - that will work on IE, Chrome, Firefox and Safari will be something like this:

Orchard: Change Page Title

2012-11-13T18:48:00.000+02:00

Hello,

Open the View (.cshtml) file that you want with a custom title and add this code at the top of the file:

Code:

@{
    Layout.Title = T("Custom Title | EXTREMEDEV").Text;

Orchard: Change favicon

2012-10-29T21:51:00.003+02:00

Hello,

As you all probably know Orchard is a free, open source, community-focused project aimed at delivering applications and reusable components on the ASP.NET MVC platform.

So, now about the favicon, to change the default Orchard's favicon you need either to install the Favicon module, which I think is too complicated for this case, or to override the location of the favicon by overriding the default Document.cshtml template - just copy/paste to your theme.

You will find something like below in Document.cshtml:

Code:

RegisterLink(new LinkEntry {Type = "image/x-icon", Rel = "shortcut icon", Href = Url.Content("~/.../FavIcon.ico")});

Change the path of the href attribute to where your favicon is, and here it is you have your own favicon.

Happy coding!!!

SSIS on SQL Server 2008 R2

2012-05-21T23:18:00.001+03:00

Hi all,

These days I had a chance to take a look at SQL Server Integration Service 2008 R2 (SSIS) and do you know what? it is a really good thing when you need to Extract, Transform and Load (ETL) data from a DataBase to another.

However, unfortunately it is very buggy and is still like something that is not fully implemented, like not all the functionality was implemented till the end.
What I've found during several days of investigations on SSIS is:
1) it is very hard to maintain;

After several days, I have found on the internet how to remove this worm. Read below:

Try locate in processlist file called mdm.exe, and kill the process, Then download any startup program management utilities - for example Nirsoft Startup.cpl and look for "Windows Firevall engine" that references the "c:/windows/mdm.exe". Delete or disable those in startup and delete the file itself under c:/windows/mdm.exe

Transaction count after EXECUTE indicates that a COMMIT or ROLLBACK TRAN is missing. Previous count = %ld, Current count = %ld

2012-02-17T16:13:00.001+02:00

Such an error has appeared these days to me in SQL using SPROC in another SPROC where these are using transactions:

Msg 266, Level 16, State 2, Procedure SPROC_NAME2, Line 0
Transaction count after EXECUTE indicates that a COMMIT or ROLLBACK TRANSACTION statement is missing. Previous count = 1, current count = 2.

So what is that???
I will explain.

Carousel with variable item-sizes

2012-02-13T10:43:00.002+02:00

Carousel with variable item-sizes

I have implemented a Javascript / jQuery + CSS Carousel which is auto-scroll-able, but also has the possibility to manually scroll the items.

The biggest advantage of this carousel is that you can have items of different size and the carousel is not changing its size.

Here is the how you define the items that will be displayed in the Carousel:

Code:

<li><a href="#"><img src="./img/item5.png"></a></li>
<li><a href="#"><img src="./img/item3.png"></a></li>

To configure the speed of scrolling when auto-scrolling you need to amend this line of code:

Skype haha foto http://goo.gl/...?Facebook.com-IMG....JPG

2012-02-12T18:18:00.000+02:00

Many of my friends have sent me some "photos". Something like: haha foto http://goo.gl/...?Facebook.com-IMG....JPG

All these messages were sent through skype groups.
This of course is something like virus.

Because when you click on that link it is being opened in browser and there is no photo in it, however it looks like it is installing something on your computer and from now and on you are also sending group messages through skype :) with the message: haha foto http://goo.gl/...?Facebook.com-IMG....JPG

I very much believe that it's purpose is not only to send that link, but it should also do something in the background, I still don't know what, maybe some key logging of your credentials to email/skype/facebook and others.

Override jQuery.val() and jQuery.val(value)

2012-01-23T15:49:00.001+02:00

Hi all,

Sometimes there are cases when you need to do something when $.val() and $.val(value) from jQuery is called, but then you still want the default behavior to be kept. Here is an example of how you could do that:

Code:

var originalVal = this.originalVal = $.fn.val;
$.fn.val = function(value) {
    if (typeof value == 'undefined') {
        alert('Getting the value');
        return originalVal.call(this);
    }
    else {
        alert('Setting the value');

        return originalVal.call(this, value);
    }
};

I for example have used it for a jQuery widget, I wanted to override the default behavior of the val() function when this is performed on the element for which a widget was used. So what I have done is I have added a custom attribute to the element for which I am using the widget and then in the val() I am checking the presence of that attribute - just like below:

SQL: Rename Column/Table Name

2012-01-11T12:35:00.001+02:00

Hi All,

We all sometimes need to rename a column/table from our database, however we do not want to drop all our records from the table where the column is renamed or the name of that table is changed.

For that there is such a nice SPROC in MS SQL: sp_rename.

This SPROC can be used to rename any user-created object in current DB.

However there is also a caution:

ANTS Memory Profiler 7.1 without license

2011-11-25T14:59:00.001+02:00

Hi All,

The trial period of 14 days of your ANTS Memory Profiler has passed.

You are now searching for a license for ANTS Memory Profiler?
Or are you searching for a crack for ANTS Memory Profiler?
Or are you searching for a keygen for ANTS Memory Profiler?

No need to do that anymore because there is an easy way to use it without having a license, crack or keygen (Note: the version that I am using is 7.1).

So what to do?

SQL Performance Tips 4

2011-11-23T16:59:00.000+02:00

Hi All,

Again me with some more SQL Performance Tips.

If you have a lot of tables with which you have to join and those tables are big then pay attention to the order of how you join those tables because the order matters.

Why the order of the tables in joins matters?

It is because even if the result of your query returns only a few of records, lets say 7 records, it doesn't mean that it will run fast, and it will not run fast because during the first joins your tables can "return" thousands, millions or even more records with which the SQL Server will be working further.

So the idea is that you have to use the Actual Execution Plan to see what is Estimated Number of Rows with which the SQL Server will be working with.

Try to filter the data using the joins, so that less data remains to be processed, and less time it takes to the SQL Server to return the result to you.

Good luck,
Roman

SQL Performance Tips 3

2011-11-18T06:00:00.000+02:00

Hi All,

Me again with another SQL Performance tip.

Another way to optimize a query is using the Actual Execution Plan.

Well, first of all by using it you will see what indexes are missing, what table or join is causing the performance issue, which join is returning a lot of rows and many more.

It worth learning how to use the Actual Execution Plan.

Now about indexes, you must keep in mind that not all indexes that are suggested to be created by Actual Execution Plan are good to be created, and this is for several reasons:

SQL Performance Tips 2

2011-11-17T06:00:00.000+02:00

Hi All,

Here are some more tips on SQL Performance.

SET NOCOUNT
So what is it useful for?
First of all what is it doing: Stops the message indicating the number of rows affected by a Transact-SQL statement from being returned as part of the results.

Which means that when you do not need the number of rows affected to be returned from the SPROC then write that at the beginning of the SPROC. Why? because it will reduce the traffic and the execution time of your SPROC.

SQL Performance Tips 1

2011-11-16T15:04:00.001+02:00

Hi All,

By working at some performance issues with SQL Stored Procedures, Views and Functions I had to make some investigations on SQL performace, how to do that, I've been searching a lot to find some tips.

So the first tip is: Avoid using CURSORS.

Yes, avoid cursors, do everything to avoid cursors.

Often time people say to me that for their case it is not possible to avoid cursors, and often times I prove them that it is possible.

When there is just a few things that you could do with a set of data then try to do that in some statements by joining the data, instead of going through each item.

It is not always clear that cursors could be avoided, this is why you have to think several times if it is really not possible to avoid them.

Migrating .wdproj From VS 2008 to VS 2010

2011-10-27T10:51:00.000+03:00

Hi All,

Do you want to work under Visual Studio 2010 and your project is currently working under VS 2008?
All you need to do is to to convert your projects into a VS 2010 Version.

However there could be a small problem that we are going to solve: not all projects can be converted, and I am speaking about Web Deployment Projects. In order to make those available for VS 2010 you will need to download and install the "Visual Studio® 2010 Web Deployment Projects - RTW".

Now if you want to migrate your project from a .Net 3.5 to .Net 4.0 then you can face an error like this:

"Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive."

Hi everyone,

Have you ever tried to use Visual Studio's Memory Profiler?
I have recently had a need to profile a .Net application and was searching for a memory Profiler tool, and that was the moment when I have found out that Visual Studio 2008 Development Edition has it's own memory Profiler.

I decided to search for a quick guide and have found several of those on the internet.

Unfortunately when I started my application using that profiler my computer showed me the Blue Screen of Death.

The problem when putting my own iframe behind a element that I want to position somewhere on the page with jQuery UI position function it throws the error. The error is thrown because jQuery UI position is automatically calling the bgiframe function if it exists. Here is the code:
