you can download colorbox from

You can find jQuery Colorbox examples here

Step 2: Add the following inside < head > tag

Step 3: ASP.Net Listview using CommandArgument to delete the item

Password Encryption Using ASP.Net

Password Encryption can be used for encrypting password. Here in this article I am going to explain how you can create the hashed passwords. This method can be used for storing passwords in the credentials section of a database or inside an XML file.

Some of commonly used Hash Encryption Algorithms are ‘MD5‘ and ‘SHA-1

SHA-1 (Secure Hash Algorithm 1) is slower than MD5 but the message digest is larger, which makes it more resistant to brute force attacks. Therefore, it is recommended that Secure Hash Algorithm is preferred to MD5 for all of your digest needs.

Creating Hashed Passwords Using “SHA-1” (Secure Hash Algoritham)

  • Source Code “VB.NET”

    Dim strEncryptPassword As String
    strEncryptPassword = FormsAuthentication.HashPasswordForStoringInConfigFile(txtPassword.Text, “sha1”)

  • Source Code “C#”

    string strEncryptPassword;
    strEncryptPassword = FormsAuthentication.HashPasswordForStoringInConfigFile(txtPassword.Text, “sha1”);

ASP.Net FileSystem Using GridView

To access directory information, we can use either the “Directory” or the “DirectoryInfo” class; in case if we need to access file information, we have to use either the “File” class or the “FileInfo” class.

To display a directory files in a DataGrid ; we have to assign the string array to the DataSource Property and then call the DataGrid using DataBind() Method. We are using DirectoryInfo for listing directory files, however we can also display other attributes like file size etc…

The main cause of this type of error is may be you wrote the connection string inside the quotes like this

Dim myConn As New SqlConnection(“strConnectionString”)

Modify your code like this and try again

Dim myConn As New SqlConnection(strConnectionString)
