Get And Set The System Date And Time using c#

Have you want to get your current system date and time as well as set the system date and time using c# code.
here it is, C# code snippet that uses unmanaged code to retrieve the current date and time of the Windows operating system, and also sets it to the specified values.

1. using System;
2. using System.Collections.Generic;
3. using System.ComponentModel;
4. using System.Data;
5. using System.Windows.Forms;
6. using System.Runtime.InteropServices;

35. private void button1_Click(object sender, EventArgs e)
36. {
37. // Set system date and time
38. SystemTime updatedTime = new SystemTime();
39. updatedTime.Year = (ushort)2008;
40. updatedTime.Month = (ushort)4;
41. updatedTime.Day = (ushort)23;
42. // UTC time; it will be modified according to the regional settings of the target computer so the actual hour might differ
43. updatedTime.Hour = (ushort)10;
44. updatedTime.Minute = (ushort)0;
45. updatedTime.Second = (ushort)0;
46. // Call the unmanaged function that sets the new date and time instantly
47. Win32SetSystemTime(ref updatedTime);
49. // Retrieve the current system date and time
50. SystemTime currTime = new SystemTime();
51. Win32GetSystemTime(ref currTime);
52. // You can now use the struct to retrieve the date and time
53. MessageBox.Show("It's " + currTime.Hour + " o'clock. Do you know where your C# code is?");

Resolving w3c validation issues details...

For those who are wondering why should one bother with W3C Validations,
please read Why should we Validate our WebSites?

When validating your website using W3C some weird errors might occur

An Example is

there is no attribute "border".

even if you haven't given the border attribute

The Reason

The ASP.NET engines sees the W3C validator as down-level browser and renders
non-XHTML compliant code. Your code is most likely fine. The problem is with
ASP.NET.

The Solution(Step Wise)


1.Right Click on your Solution Explorer
2.Click on Add ASP.NET Folder ---> App_Browsers
3.Now Click on App_Browsers ---> Add New Item
4.A dialog Box now pops up with some Visual Studio Installed Templates.
Select the Browser File Template from there, change the name as W3CValidations.browser(any other convenient name also) and Click on the Add Button
5.Delete the whole XML MarkUp code inside the W3CValidations.browser
6.Place the following code instead

7.Now upload this Folder nad File to your Hosting Service
8.Re Validate using W3C Validator
9.Bingo! You got a Clean Validation Certificate.
10. Show off the Validation Certificate to all those who cares [:)]

Msgbox for ASP.Net

Messsagebox function for ASP.Net.
Call this function from the server side, and a msgbox will appear on the client browser. As a bonus, the msgbox javascript is added after the rest of the form, so the browser displays the html for the page and then the msgbox.


Declaration:

Error - GetTypeHashCode() : no suitable method found to override

I found it very useful so I want to it here. I found a need for it while transferring my site from vb.net to C#.

After creating an ASP.NET web form using Microsoft Visual Studio 2005 or Microsoft Visual Studio 2005 Team Suite, I renamed the form from it's default name "Default.aspx" to a more user-friendly name "Order.aspx" within MS VS. After adding more code to the C# code-behind page, I discovered the following line: "public partial class _Default"

Being new to the ASP.NET programming language, I changed the "_Default" to "Order" thinking MS VS had failed to rename items within the code it generates. This caused the following error to display at debug/run time: "GetTypeHashCode() : no suitable method found to override"

There were several other errors displayed as well.

The class names must match between the .aspx and .aspx.cs web pages. Here is what the lines in each file should look like:

In the ASPX source file: %@ Page Language="C#" codefile="FormName.aspx.cs" Inherits="FormName_aspx" %

In the ASPX.CS source file: public partial class FormName_aspx : Page

Once I changed the .ASPX file to match the class name in the .ASPX.CS file, the errors were resolved.

Tricks with Server.MapPath

The Server.MapPath method can be used to retrieve several interesting properties about the running ASP.NET application, for example:

' the current directory
currDir = Server.MapPath(".")

' the parent directory
parentDir = Server.MapPath("..")

' the application's root directory
rootDir = Server.MapPath("/")

For example, you can store the application's root directory in an Application variable, and use it to dynamically build physical paths to other files and directories.

ASP.NET: How To Name A Variable Or Property Using .NET’s “Reserved” Words

Let’s say you want to give your class a boolean property named Error that gets turned on or off if something goes awry in your code. You would think that you can’t do this because the word “Error” is reserved by .NET. However, there is a way. All you have to do is put Square Brackets around the word! For instance:

Visual Studio.NET: How To Comment/Uncomment Large Blocks of Code

Hello .Net Coders,
This One is for you,
To comment a large block of code (VS.NET), highlight the area you want to comment out and hold Ctrl and press K and then C.
To uncomment, highlight the commented area and hit Ctrl + K + U.
The mass uncommenting merely removes the forward-most apostrophe, so if you have actual comments in your commented code that were included in your initial highlighted region, they will remain comments upon uncommenting.

This tips is using at debugging time is most used by me.

SQL Server 2005 Paging Performance Tip

This quick tip demonstrates how to get the total rows as part of the paging query as well as how avoid a common coding error with joins that can harm performance.
I've seen the following technique in several beginner code samples for demonstrating SQL Server 2005's ability to return paged results.
I've added the TotalRows = Count(*) OVER() line to demonstrate how return the total rows returned above and beyond the row count for the paged set. This removes the need for a second query to get the total rows available for paging techniques in your application. In your application, just check to make sure your resultset has records, then just grab the first record and retrieve its TotalRows column value.
Notice that in this query, the JOIN between the Orders table and the Users table is being run across all records that are found NOT just the records returned in the paged set.
declare @StartRow int
declare @MaxRows int
select @StartRow = 1
select @MaxRows = 10
select * from
(select o.*,u.FirstName,u.LastName,
TotalRows=Count(*) OVER(),
ROW_NUMBER() OVER(ORDER BY o.CreateDateTime desc) as RowNum
from Orders o , Users u
WHERE o.CreateDateTime > getdate() -30
AND (o.UserID = u.UserID) )
WHERE RowNum BETWEEN @StartRow AND (@StartRow + @MaxRows) -1

If you adjust your query as follows, you will see a substantial boost in performance. Notice this query only performs the join on the returned resultset which is much, much smaller.

SELECT MyTable.*,u.FirstName,u.LastName
FROM
(SELECT o.*, TotalRows=Count(*) OVER(),
ROW_NUMBER() OVER(ORDER BY o.CreateDateTime desc) as RowNum
FROM Orders o
WHERE o.CreateDateTime > getdate() -30
) as MyTable, Users u
WHERE RowNum BETWEEN @StartRow AND (@StartRow + @MaxRows) -1
and (MyTable.UserID = u.UserID)

UTF8 encoded php mail function

create a php mail function that can handle UTF8 characters across most email readers.

The problem with the php mail is that it does not encode the names and subjects and they could get lost in the transport or be misinterpreted from the email readers. This function actually does the proper encoding and overcomes the php mail deficiency.
—————————–
function UTF8_mail($from,$to,$subject,$message,$cc=”",$bcc=”"){
$from = explode(”<”,$from );
$headers =“From: =?UTF-8?B?”.base64_encode($from[0]).”?= <”. $from[1] . “\r\n”;
$to = explode(”<”,$to );$to = “=?UTF-8?B?”.base64_encode($to[0]).”?= <”. $to[1] ;
$subject=”=?UTF-8?B?”.base64_encode($subject).”?=\n”;
if($cc!=”"){$cc = explode(”<”,$cc );$headers .= “Cc: =?UTF-8?B?”.base64_encode($cc[0]).”?= <”. $cc[1] . “\r\n”;}
if($bcc!=”"){$bcc = explode(”<”,$bcc );$headers .= “Bcc: =?UTF-8?B?”.base64_encode($bcc[0]).”?= <”. $bcc[1] . “\r\n”;}
$headers .=“Content-Type: text/plain; ”. “charset=UTF-8; format=flowed\n”. “MIME-Version: 1.0\n”. “Content-Transfer-Encoding: 8bit\n”. “X-Mailer: PHP\n”;
return mail($to, $subject, $message, $headers);
}
UTF8_mail(“Γιω�?γος Κοντοπουλος ”,“First Last ”,“Θέμα Subject”,“Κείμενο Text”,“”,“Κ�?υφός Φίλοςhidden_friend@email.com”);
—————————–
All this function is accomplishing is to encode each
Name
to
=?UTF-8?B?zpzOuc+HzrHOu863z4I=?= email@domain.com

The emails themselves don’t need to be encoded since an email conventionally can only consist of of latin characters but, we could also confuse the mail server if we did encode them.

Sending E-Mail(s) in PHP

PHP mail() function
E-mails in PHP can be easily sent using the library function 'mail'. This function takes four arguments to send E-mails from a PHP web page and returns 'true' upon successful delivery of Email. The parameters of this function are as follows:
-Recipient E-mail address
-E-mail Subject
-E-mail message (body)
-Headers and additional parameters like the Sender E-mail address
Syntax:
mail( string to, string subject, string message [, string additional_headers [, string additional_parameters]] )

This function returns the boolean value 'True' if the mail is sent successfully, otherwise it returns 'False'.

Example:
To : textbox
From : textbox
Subject : textbox
Message(body) : textbox or textarea
Send : button
Above forms shows how to send email through PHP. And code for the above examples given below, use this code and try it.

Sample PHP Code
//Check whether the submission is made
if(isset($hidSubmit)){
//Declarate the necessary variables
$mail_to=$txtEmailto;
$mail_from=$txtEmailfrm;
$mail_sub=$txtSub;
$mail_mesg=$txtMsg;
//Check for success/failure of delivery
if(mail($mail_to,$mail_sub,$mail_mesg,"From:$mail_from/r/nReply-to:$mail_from"))
echo "E-mail has been sent successfully from $mail_sub to $mail_to";
else
echo "Failed to send the E-mail from $mail_sub to $mail_to";
}
?>
