Create A New SQL Server Database Basing From A Renamed DB (mdf/ldf) Files

I recently created a copy of Northwind database and called it NorthwindBootstrap. This database has a built-in membership tables added to it. The copy includes both of mdf and ldf files. My next step is to create a new database based from the recently copied/renamed files in which I have no idea on how to do it. After doing some research, I stumbled upon a t-sql script based from my requirement. USE [master] GO CREATE DATABASE [NorthwindBootstrap] ON ( FILENAME = N 'C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\NorthwindBootstrap.mdf' ), ( FILENAME = N 'C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\NorthwindBootstrap.ldf' ) FOR ATTACH GO Cheers! :)

The specified cast from a materialized 'System.Int16' type to a nullable 'System.Int32' type is not valid In C#

Based from the issue, the fix is to check the database field against the view model class. In my case, the database field is smallint (nullable). So, the fix is to change the model code from int datatype: public int? StockOnHand { get ; set ; } To Int16 datatype: public Int16? UnitsInStock { get ; set ; } :-)

jQuery Intellisense Not Working In External Javascript File Using Visual Studio 2013

Image
Hello, In order for the jQuery intellisense to work in Visual Studio 2013, perform the following steps. 1. Proceed by clicking Tools -> Options -> Text Editor -> JavaScript -> Intellisense -> References. 2. Change Reference Group to Implicit (Web)   By default a reference has been added to _references.js. If not, add a new reference file under Scripts folder. 3. Open _references.js file using your Visual Studio IDE or any text editor software. 4. Add reference path to jquery files (.js, .min.js, and .intellisense.js). 5. Close Visual Studio and Open it again. (I was struggling for hours as to why performing steps 1 through 4 didn't work. This step fixed the issue) Reference: jQuery intellisense not working in VS 2012 Regards, :)
