Passing variable from code behind to HTML tag in ASP.NET

Some how in some case, we want to directly passing variable that we already declare in ASP.NET with code behind to the HTML tag, like <input type = “TEXT”> tag in HTML, we can do that just with the simple code, here is the way:

Declare test as a property (at the class level) instead of a local variable, then refer to it as you currently do in your markup (aspx).

VB.NET 10 (automatic properties):

Protected Property test As String = "Test" 

---------------------------------------------

Pre-VB.NET 10 (no support for automatic properties)

Private _test As String
Protected Property Test As String
Get
     Return _test
End Get
Set(value As String)
     _test = value
End Set
End Property

——————————————————–

place that variable in HTML tag that you want to place, such as :

<input type=”TEXT” name=”SomeThing” size=”50″ maxlength=”250″ value = “<%= test %>”>

 

that’s all, hope this helpful

The DATEPART function on SQL Server

The DATEPART function.

This function will take a date/time expression and return a single part of the date, such as hour, minute, month, day, etc. The syntax for using DATEPART is:

Quote

DATEPART(datepart, date)

Where the datepart is one of the following:

  • Year: yy, yyyy
  • Quarter: qq, q
  • Month: mm, m
  • dayofyear: dy, y
  • Day: dd, d
  • Week: wk, ww
  • Weekday: dw
  • Hour: hh
  • Minute: mi, n
  • Second: ss, s
  • Millisecond: ms.

let say the date right now is 23-03-2012

if we want to display the day, use :

DECLARE @date DATETIME
SET @date = '2012-03-23 10:31 PM'
SELECT DATEPART(dd,@date)
--- the query will return = 23
---------------------------------------

if we want to display the Month, use :

DECLARE @date DATETIME
SET @date = '2012-03-23 10:31 PM'
SELECT DATEPART(mm,@date)
--- the query will return = 03
---------------------------------------

if we want to display the Year, use :

DECLARE @date DATETIME
SET @date = '2012-03-23 10:31 PM'
SELECT DATPART(yyyy,@date)
--- the query will return = 2012
ETC

SQL Server Date Formats

One of the most frequently asked questions in SQL Server forums is how to format a datetime value or column into a specific date format.  Here’s a summary of the different date formats that come standard in SQL Server as part of the CONVERT function.  Following the standard date formats are some extended date formats that are often asked by SQL Server developers.

It is worth to note that the output of these date formats are of VARCHAR data types already and not of DATETIME data type.  With this in mind, any date comparisons performed after the datetime value has been formatted are using the VARCHAR value of the date and time and not its original DATETIME value.

Enable content expiration under IIS 7

In IIS6, it was with the website properties –> HTTP Headers. Here in IIS7, you can do this on the “HTTP Response Headers” feature on the website.

  • Select the website in the Connections pane.
  • Double click on the “HTTP Response Headers” feature in the features pane
  • In the action pane, click on the “Set Common Headers…”

Now, you know what to select. You should enable the HTTP Keep-Alive on this popup only.

Run CGI program under IIS 7.0

Looking around I didn’t find a good documentation on how to get good old CGI’s running on IIS 7 or 7.5. Here is a quick walkthrough:

1. Let’s write a quick CGI:
Take the following code and save it as simplecgi.cs in the directory c:\inetpub\wwwroot\cgi

using System;
using System.Collections;

class SimpleCGI
{
    static void Main(string[] args)
    {
        Console.WriteLine("\r\n\r\n");
        Console.WriteLine("<h1>Environment Variables</h1>");
        foreach (DictionaryEntry var in Environment.GetEnvironmentVariables())
            Console.WriteLine("<hr><b>{0}</b>: {1}", var.Key, var.Value);
    }
}

2. Change into the C:\inetpub\wwwroot\cgi directory and compile the source by using the following command-line:

%windir%\Microsoft.NET\Framework\v2.0.50727\csc.exe SimpleCGI.cs
