Real Quick JSON Example

JSON is better to handle than XML. Was using it in a project so thought to post here,

<div id="dvResult">Loading...</div>

<script>
var data = [
    {"firstName":"Michael","lastName":"Jackson","SSN":"123456789"}, 
    {"firstName":"Barack","Obama":"Smith","SSN":"124456789"},
    {"firstName":"Peter","lastName":"Jackson","SSN":"125456789"}
];

var x = '';

for (i = 0; i < data.length; i++)
{
    x = x + data[i].firstName + " " + data[i].lastName + " " + data[i].SSN + "<br/>";
}

document.getElementById("dvResult").innerHTML = x;

</script>

Bulk Site Collection Deletion using PowerShell

Description:
Following powershell reads the list of site collections from the file and deleted them:

Add-PSSnapin "Microsoft.SharePoint.PowerShell"

function WriteLog
{
    Param([string]$message, [string]$logFilePath)
    Add-Content -Path $logFilePath -Value $message
}

$LogFile = "G:\DeletedSites.log"
$ListFile = "G:\List.csv"

$Sites = Import-CSV $ListFile

ForEach ($S in $Sites) 
{
    
    try
    {  

        $URL = $S.URL

        $Now = [System.DateTime]::Now
        $MSG = $Now.ToString() +  " | Deleting site: " + $URL
        write-host $MSG
        WriteLog $MSG $LogFile
        
        Remove-SPSite -Identity $URL -GradualDelete -Confirm:$false


    }
    catch [system.exception]
    {
        $Now = [System.DateTime]::Now
        $MSG = $Now.ToString() + "Exp: " + $_.Exception.Message
        write-host -f red $MSG
        WriteLog $MSG $LogFile
    }

    $Site = $Null
}

write-host "Done."

Get Claims Programmatically

And that's how you get all the claims for a user programmatically in .NET. Almost similar to my older post:

public void GetClaims()
{

    System.Security.Principal.IPrincipal ipl = System.Web.HttpContext.Current.User;
    System.Security.Claims.ClaimsIdentity claimsIdentity = (System.Security.Claims.ClaimsIdentity)ipl.Identity;
    foreach (System.Security.Claims.Claim oClaim in claimsIdentity.Claims)
    {
        Response.Write("ClaimType [" + oClaim.Type.ToLower() + "] has value [" + oClaim.Value + "]");
    }

}

Get Query String from JavaScript

I use this javascript function in every other project and every time I have to go to the internet and search for it. I am just too lazy to look and copy it from the old projects. So I am copying it from the internet to save it in my personal source code repository.

function getParameterByName(name) {
    name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
    var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
        results = regex.exec(location.search);
    return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}

var strValue = getParameterByName('Value');

document.write(strValue);
