Find total number of vowels in a string in JavaScript:

This article explain how to find Vowels in a String and how to find total number of vowels in a string in JavaScript. I have written simple script for checking vowels in a string in JavaScript. I have used regular expression.

<html>
<head>

    <script>
function findVowels() {

var str=document.getElementById('name').value;  

   var vowelC = 0;
var total_findVowels="";
     for (var i = 0; i < str.length; i++) {

     if (str.charAt(i).match(/[a-zA-Z]/) != null) {

        // findVowels

        if (str.charAt(i).match(/[aeiouAEIOU]/))
  {

 total_findVowels=total_findVowels+str.charAt(i);            
 vowelC++;

        }

     }
   }
    document.getElementById('findVowels').value=total_findVowels;
 document.getElementById('findVowels_count').value=vowelC;
   alert("Total Number of findVowels: " + vowelC);
 

}
    </script>

</head>
<body>
<div style="background-color: skyblue; padding:20px">
    <table border="0" cellpadding=3" cellspacing="3">

c# - how to delete all files and folders in a directory?:
This examples shows how to delete all files (*.*) from a folder in C#.
First, you need to get the list of file names from the specified directory (using static method Directory.GetFiles. Then delete all files from the list.
Delete all files
C# code

using System.IO;

string[] filePaths = Directory.GetFiles(@"d:\Images\");
foreach (string filePath in filePaths)
  File.Delete(filePath);

Delete all files (one-row example)
To delete all files using one code line, you can use Array.ForEach with combination of anonymous method.
C# code

Array.ForEach(Directory.GetFiles(@"d:\Images\"),
              delegate(string path) { File.Delete(path); });

C# Get All Files from a Folder:
This post shows how to get list of file names from a directory (including subdirectories). You can filter the list by specific extension.
To get file names from the specified directory, use static method Directory.GetFiles. Lets have these files and subfolders in "d:\YourDir" folder:

Get files from directory
Method Directory.GetFiles returns string array with files names (full paths).

C# Code

using System.IO;

string[] filePaths = Directory.GetFiles(@"d:\Images\");
// returns:
// "d:\Images\dotnetcluster.png"
// "d:\Images\home.jpg"

Get files from directory (with specified extension)
You can specify search pattern. You can use wildcard specifiers in the search pattern, e.g. „*.png“ to select files with the extension or „a*“ to select files beginning with letter, a“.

C# Code

string[] filePaths = Directory.GetFiles(@"d:\Images\", "*.png");

// returns:
// "c:\Images\dotnetcluster.png"

Get files from directory (including all subdirectories)
If you want to search also in subfolders use parameter Search Option. All Directories.

C# Code

string[] filePaths = Directory.GetFiles(@"d:\Images\", "*.png",

                                         SearchOption.AllDirectories);
// returns:
// "d:\Images\dotnetcluster.png"
// "d:\Images\Posts\header.png"

Sending Email With an Attachment in asp.net using c#

sending mail with attachment in asp.net,c#:
In this tutorial you will learn how to send attachment with email in asp.net using c#. To send an email with attachments, the ASP.NET process (or the ASP.NET impersonated account) will need permission to read the file, and attach it to the MailMessage class. You can attach a file using FileUpload Control and put the file in memory stream. In this example I'm using smtp.gmail.com as my SMTP server. You can put your gmail login credentials and send mail with attachment.

In .aspx file

 <table style="padding-left: 10px; background-color: #4B8DF8; color: #fff; font-weight: bold;">
        <tr>
            <td colspan="2">
                <span class="primary"><b>Mail With Attachment:</b></span>
