Select increasing number



I need to create a select statement in which one of the columns is a running count starting from a number of my choosing. So like this:


Col1 Col2 Num
Row  Row  1
Row  Row  2
Row  Row  3
Row  Row  4
How can I do that without using variables or a loop etc?

Edit: What I mean is something similar to IDENTITY-function without having to use it with INTO.

Linq: how to share parameters between lambda expressions ?

When using Linq to objects, you will quickly feel the need to pass some parameters from a method to another but it's not so easy because each Linq method is not calling the following one. In a Linq sequence, each method is using the result computed by the previous one. So, local contexts are not visible from one method to another.
The compiler is using two technical different ways to let parameters go out of a method.

Various SQL Expressions

A comparison is a Boolean operation that produces a true or a false result, depending on the values on which the comparison is performed. A comparison is performed between two values of the same type; for example, you can compare two numbers, two characters, or the names of two cities. To support comparisons, Transact-SQL provides all necessary operators.

What is Lambda Expressions In LINQ

A lambda expression is an anonymous function that can contain expressions and statements, and can be used to create delegates or expression tree types.

All lambda expressions use the lambda operator =>, which is read as "goes to". The left side of the lambda operator specifies the input parameters (if any) and the right side holds the expression or statement block. The lambda expression x => x * x is read "x goes to x times x." This expression can be assigned to a delegate type as follows:

dynamically adding sql server columns based on number of files in fileuploader


I want to create a new table to sql database at runtime.  The column names would be "Name", "Date", "Event".  I would also like to have one more column name "Image" but the problem is that since the amount of images will vary, I want the application to count the amount of files in the Multiple fileuploader and then add a image column to the table for the respected amount of files. 

For example if i am uploading 3 files in the multiple fileuploader, the names should be "Name", "Date", "Event", "Image1", "image2", Image3"

I also would like that table name to be name dynamically from the textbox Name when the user enters the information.


I have the following code to make a new table, but I dont know how to name the fields at runtime like previously asked please help!!!

Embeb a variable number of videos


I need to provide some alternate content for my non-Flash users.

I have a directory of video files that is scanned using the DirectoryInfo() function, and I want to use the results to embed all files ending in ".mov" in QuickTime players on a web form.

How would you approach this? Right now I am using the count on the array of videos to determine how many times to repeat the embed code.  But this seems inelegant.

Is there a way to have a single QuickTime player.ascx control that gets duplicated according to the number of videos available for display?

Article commenting by line number


I'm wondering what's the best way to approach an online article system that allows users to comment by clicking on the line they are commenting about? Essentially the same way Adobe Acrobat works with comments where you can click anywhere and the text is saved for that location.

I'm assuming a mix of jQuery would be the crux of the interface. The system would need to save comments so that when another user logs in, they will also see the other comments but they can´t edit them - only add their own.

Any suggestions would be great.
