An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

The database project requires an active database connection to load at design time. Probably it uses that to compile/verify scripts. The problem here is Visual Studio is not able to connect to any such instance. Following are few solutions (these worked for me)

1. Make sure the instance to which you want to connect is running and allows remote connections.
2. After performing step 1, if it is still not loading then you may need to start the SQL Browser Service. Make sure it’s running.
3. If the problem is still there, it has to be fixed from Visual Studio itself. Actually database project do not store to which instance it can connect. It’s a Visual Studio setting. In VS2008 go to Tool > Options > Database Tools > Design-time Validation Database > Connection Options. Specify your instance name here like “.\SQLEXPRESS”

If the problem is still there post it to MSDN forums

In addition to those common features, this phone features something new. In this post I’m going to write those specifications which you won’t be able to know unless you buy the phone. Here are a few…

1. Bright display! I can read text even in sun light. The phone comes with preloaded high contrast images, watching those you can see how much color contrast it delivers !!! - far from any other manufacturer in the same prize range.
2. 3.5mm jack support. This allows any kind of head phones to be used with the phone.
3. Text Copy/Paste feature. Handy for coping/writing SMS.
4. J2ME with support of - Internet access, File system read/write access API, camera API, Messaging APIs, automatic start, local connectivity API, running Java apps in background.
5. You can have at max 1000 Contacts, 1000 SMS memory and 380 events/tasks. (~26MB internal memory)
6. 5 alarms, and you can also set FM alarm.
7. Two kind of keypad lights. White for normal purpose and Orange when Walkman is running. The orange light blinks on the beats of the song.
8. USB charging: When you connect this phone to PC it start charging from the USB cable.
9. Flash Menu: The main menu in this phone is built using Flash Lite. You can switch the orientation and look of the menu. Menu items can be tiled, horizontally or vertical aligned, and can have cool animations.
10. Synchronization is one of the most important service that we should use. In short taking backup of the phone data. I sync my phone regularly with PC. The phone supports synchronization via USB data cable, Bluetooth, or internet server.
11. Stereo Bluetooth, Picture Blogging, Voice Dial + Playing Caller’s name, Big Fonts, Video Ringtone, etc;

Go and get the phone… it’s a worth buy cellphone.

Note: The camera is not good as compared to ‘K’ series (remember it’s Walkman phone, and this is acceptable). Still it supports EXIF, Night Mode, Effects, Self Timer, Low shutter sound, etc;

a. Limit the code block. Attempt to wrap one or two statements within try.

b. If an exception is eaten, log details to some logging mechanism. In short never write empty catch catch(Exception) {}.

c. Never eat exception that indicates some bad behavior of code execution like - ArgumentNullException,

NullReferenceException,

ArgumentNullException,

InvalidCastException,

InvalidOperationException,

AccessViolationException, etc;

d. There is a big difference between throw and throw exeception statements. This is in terms of resetting stack trace which the later does. If you are writing a framework or want to hide your internal implementation use throw exception, otherwise use throw only.

Tiles: The very first observation is – not whole map is fetched at once. Instead the entire map is divided into tiles and a series of Ajax requests are fired to retrieve some part of the actually map. As soon as a tile is fetched it is displayed at its position. Their position is well calculated no matter user drags the maps while requests are on the way. The benefit here is, the user interface remains responsive and it makes user eager to analyze an area of map as soon as it’s available.

Overlaying: The tiles can be considered basic unit of mapping applications. They are atomic and have minimal required information. The DHTML allows overlapping one tile (image) over another and makes development easier. Here is how.

For each type of data there exists an independent tile. The Ajax application retrieves these tiles and overlaps one above another. For example - the user requests to see map and satellite image together, and here is how the rendered image is showed.

Tiles are Independent: Each tile is an independent unit and its request can be customized from client browser itself. For example making a request of http://kh2.google.com/kh?n=415&v=22&hl=en&t=trtssqrtqsqqtqq returns -

This is a newer image. While the request for http://kh2.google.com/kh?n=415&v=21&hl=en&t=trtssqrtqsqqtqq yields and older image for the same area.

Here the difference in the requests is of a single parameter ‘v’ and as per my guess its ‘version’. The next parameter ‘t’ seems a combination of zoom index, and the corner coordinates. For tiles of type map having some text, their language can be controlled using ‘hl=en’. Try using ‘hl=ru’ and you can see difference. So, the JavaScript executing in the client’s browser has complete control over what to display.

I’m {PREF=”ID=cfd6bd57439bc4a9:TM=1205732323:LM=1205732323:S=tT1f1NaLxjumQJbv”}. I’m a regular Internet surfer. On an average I’m online for more than 8 hours a day and that makes me to think of a new phrase - ‘my online presence’, and somewhere it may hurt my privacy.

In Web 2.0 big companies are competing to gain as much as information about Internet users that they can show targeted contents especially ads.

The game players have already begun their game. They know about what web pages I visit, they know my friends, they know what I prefer to buy online, then know which newspaper I read frequently, which mail account I use frequently, what do I search every day, what videos I watch online, where do I live, how much time I spend on Internet, what types of ads made me to click. They have my all photographs, my daily calendar/schedule, my mails (may be your credit card statements in form of emails), and all my chat conversations. They even know what music I listen, my attitude, my behavior, and even what I’m doing currently.

They say it’s all automatic, machines (computers) read and process information giving you personalized service and there is no human interference. But reality may be different. Is all that these sufficient to protect your privacy?

Here is a bigger fear, giving all of your information in the hands on one single body! A single mistake in handling such massive information can lead to world’s biggest controversy in user’s privacy.

In short, I don’t want anybody to know the fact that the wristwatch I have given to my girl-friend for her last birthday was of just 100 bucks!

But, now Ankit is back with cool and new articles to write. And one promise to the readers of my blog - such absence will not occur again. At least I’ll try to write something about my experiences, my passions, techie stuff.

1. Make sure the webpart class is inherited either from Microsoft.SharePoint.WebPartPages.WebPart or System.Web.UI.WebControls.WebParts.WebPart
2. The webpart class needs to be declared public.
3. Safe controls entry in web.config file.
4. If you are referring a webpart from GAC (i.e. assembly containing webpart class is placed in GAC) make sure the GAC version is the latest build and IIS is re-started.

My solution for this: Installed SSP (Shared Services Provider) and this problem is solved!
[ Edited:2008-03-24
I got this error while playing with stsadm.exe command
]

1. The Identity Selector dialog box is displayed only for SSL protected pages. Therefore you are required to deploy your application on a Web server and install a SSL Certificate.
2. Windows CardSpace does not work with Self Signed Certificates and will die horribly. These certificates do not have CRL field. It contains a URL that CardSpace will check for the revocation list.
3. For ASP.NET developers there is Toolbox control written by Christian Arnold. Add this to your Toolbox and you won’t need to write a single line of code. Watch demo.
4. When you use CardSpaceLogin controls you must run application over SSL. The application pool also need to be run under Local System’s identify; otherwise w3wp.exe process will not be able to retrieve server’s private key. In such case you may end up with error stating “Keyset does not exist”. Note: This is not advisory if the application pool is shared with other Web applications. [ Edited: Refer Barry Dorrans comment for more details.]
5. When using Information cards there is nothing like passwords.
6. CardSpaceLogin controls are integrated with your identify providers such as Forms Authentication. For example: If you use Information Card to register a user, his details are reflected in the identify source.

A text comment is associated with the change you made to the item. Some of the times you need to find a particular comment, but the View History tool available with Visual Studio/TFS is limited that you can’t make a search in the history results. Say you want to find all check-ins by a particular user

Here comes the purpose of this small add-in. It provides search within history comments and find a particular change-set instead of traversing the whole list. The plug-in goes one step forward and facilitates free text search in change-set fields. For example you can use change-set id, username or even date-time as search keywords!!!

The major steps involved in developing this add-in are:

1. Writing an add-in for Visual Studio 2005,
2. Getting file history from Team Foundation Server (TFS),
3. Look for the selected item in the Visual Studio IDE,
4. Free text search along with the tools to compare two files.

Visual Studio 2005 provides templates to build add-ins in few minutes. Refer www.devx.com for step-by-step guide for building Visual Studio app-ins. Additionally, you can download Visual Studio 2005 Automation Samples for detailed code illustrations with documentation.

Once you have completed the Visual Studio Add-in wizard the IDE generates Connect.cs file and dumps some code for basic functionality. The next step is to retrieve history from the TFS for selected file. Refer my previous post, Fetching file history from TFS to find out how to fetch file history objects from Version Control Server.

Moving forward we need to find out the currently selected item in the Visual Studio IDE. Visual Studio exposes various properties/objects allowing you to query almost any UI controls and get their status. The following code first finds the active window. If it is Source Control Explorer and then looks for the selected item within the same.

The following code is to compare two source code files and show visual difference. There is an API provided for the same.

Once the add-in is installed, it appears in the Tools menu within Visual Studio 2005. Open Source Control Explorer and select an item. Launch the add-in from Tools menu.

When you search for the history of a File, you can also compare it with the local version or the latest version in the source control. These option are avaiable as context menu.

Following steps are required only if you download the code and try to deploy the solution to have hands on with the code.

1. Copy the TFSHistorySearch.AddIn file to %userprofile%\My Documents\Visual Studio 2005\Addins\ directory.
2. Update the full path of the assembly TFSHistorySearch.dll under Extensibility/Addin/Assembly x-path.
3. Add reference of TFSHistorySearch.AddIn as link to the project.
