Import contact from mail service using asp.net with php

First Download openinviter from http://openinviter.com/download.php and edit example.php to adjust it for your needs

Just like, below php file (example).


include('openinviter.php');
$inviter=new OpenInviter();
$oi_services=$inviter->getPlugins();
if (isset($_POST['provider_box']))
{
if (isset($oi_services['email'][$_POST['provider_box']])) $plugType='email';
elseif (isset($oi_services['social'][$_POST['provider_box']])) $plugType='social';
else $plugType='';
}
else $plugType = '';
function ers($ers)
{
if (!empty($ers))
{
//$contents="
";
foreach ($ers as $key=>$error)
$contents.="{$error}
";
//$contents.="

";
return $contents;
}
}
function oks($oks)
{
if (!empty($oks))
{
$contents="
";
foreach ($oks as $key=>$msg)
$contents.="{$msg}
";
$contents.="

";

return $contents;
}
}

if (!empty($_POST['step'])) $step=$_POST['step'];
else $step='get_contacts';

$ers=array();$oks=array();$import_ok=false;$done=false;
if ($_SERVER['REQUEST_METHOD']=='GET')
{
$plugType='email';
if ($step=='get_contacts')
{
if (empty($_GET['email_box']))
$ers['email']="Email missing !";
if (empty($_GET['password_box']))
$ers['password']="Password missing !";
if (empty($_GET['provider_box']))
$ers['provider']="Provider missing !";
if (count($ers)==0)
{
$inviter->startPlugin($_GET['provider_box']);
$internal=$inviter->getInternalError();
if ($internal)
$ers['inviter']=$internal;
elseif (!$inviter->login($_GET['email_box'],$_GET['password_box']))
{
$internal=$inviter->getInternalError();
$ers['login']=($internal?$internal:"Login failed. Please check the email and password you have provided and try again later !");
}
elseif (false===$contacts=$inviter->getMyContacts())
$ers['contacts']="Unable to get contacts !";
else
{
$import_ok=true;
$step='send_invites';
$_GET['oi_session_id']=$inviter->plugin->getSessionID();
$_GET['message_box']='';
}
}
}
elseif ($step=='send_invites')
{
if (empty($_POST['provider_box'])) $ers['provider']='Provider missing !';
else
{
$inviter->startPlugin($_POST['provider_box']);
$internal=$inviter->getInternalError();
if ($internal) $ers['internal']=$internal;
else
{
if (empty($_POST['email_box'])) $ers['inviter']='Inviter information missing !';
if (empty($_POST['oi_session_id'])) $ers['session_id']='No active session !';
if (empty($_POST['message_box'])) $ers['message_body']='Message missing !';
else $_POST['message_box']=strip_tags($_POST['message_box']);
$selected_contacts=array();$contacts=array();
$message=array('subject'=>$inviter->settings['message_subject'],'body'=>$inviter->settings['message_body'],'attachment'=>"\n\rAttached message: \n\r".$_POST['message_box']);
if ($inviter->showContacts())
{
foreach ($_POST as $key=>$val)
if (strpos($key,'check_')!==false)
$selected_contacts[$_POST['email_'.$val]]=$_POST['name_'.$val];
elseif (strpos($key,'email_')!==false)
{
$temp=explode('_',$key);$counter=$temp[1];
if (is_numeric($temp[1])) $contacts[$val]=$_POST['name_'.$temp[1]];
}
if (count($selected_contacts)==0) $ers['contacts']="You haven't selected any contacts to invite !";
}
}
}
if (count($ers)==0)
{
$sendMessage=$inviter->sendMessage($_POST['oi_session_id'],$message,$selected_contacts);
$inviter->logout();
if ($sendMessage===-1)
{
$message_footer="\r\n\r\nThis invite was sent using OpenInviter technology.";
$message_subject=$_POST['email_box'].$message['subject'];
$message_body=$message['body'].$message['attachment'].$message_footer;
$headers="From: {$_POST['email_box']}";
foreach ($selected_contacts as $email=>$name)
mail($email,$message_subject,$message_body,$headers);
$oks['mails']="Mails sent successfully";
}
elseif ($sendMessage===false)
{
$internal=$inviter->getInternalError();
$ers['internal']=($internal?$internal:"There were errors while sending your invites.
Please try again later!");
}
else $oks['internal']="Invites sent successfully!";
$done=true;
}
}
}
else
{
$_POST['email_box']='';
$_POST['password_box']='';
$_POST['provider_box']='';
}


if (!$done)
{
if ($step=='get_contacts')
{
}
else{}
}
if (!$done)
{
if ($step=='send_invites')
{
if ($inviter->showContacts())
{

if (count($contacts)==0){}
else
{
$odd=true;$counter=0;
foreach ($contacts as $email=>$name)
{
$counter++;
if ($odd) {}
$contents.= "{$email}".",";
$odd=!$odd;
}

}

}
}
}

print_r($contents);
?>


Then create one class like that.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.IO;
using System.Net;
using System.Text;
using System.Data;

///

/// Summary description for ImportsContacts
///
public class ImportsContacts
{
public ImportsContacts()
{
//
// TODO: Add constructor logic here
//
}

public static DataTable GetDataTableFromArray(string url, string provider, string email, string pass)
{

DataTable dt = new DataTable();
///get all contact from url as array format
///split into array
object[] array = TinyEAIPostRequest(+ url +"/example.php?step=get_contacts&provider_box=?step=get_contacts&provider_box=" + provider + "&email_box=" + email + "&password_box=" + pass , string.Empty).Split(',');
dt.Columns.Add(new DataColumn("EmailID"));

for (int i = 0; i <>
{
DataRow dr = dt.NewRow();
dr["EmailID"] = array[i];
dt.Rows.Add(dr);
}
return dt;

}
public static string TinyEAIPostRequest(string strURL, string strRequest)
{

HttpWebResponse objHttpWebResponse = null;
UTF8Encoding encoding;
string strResponse = "";

HttpWebRequest objHttpWebRequest;
objHttpWebRequest = (HttpWebRequest)WebRequest.Create(strURL);
objHttpWebRequest.ContentType = "application/x-www-form-urlencoded";
objHttpWebRequest.PreAuthenticate = true;

objHttpWebRequest.Method = "GET";

//Prepare the request stream
if (strRequest != null && strRequest != string.Empty)
{
encoding = new UTF8Encoding();
Stream objStream = objHttpWebRequest.GetRequestStream();
Byte[] Buffer = encoding.GetBytes(strRequest);
// Post the request
objStream.Write(Buffer, 0, Buffer.Length);
objStream.Close();
}
objHttpWebResponse = (HttpWebResponse)objHttpWebRequest.GetResponse();

encoding = new UTF8Encoding();
StreamReader objStreamReader = new StreamReader(objHttpWebResponse.GetResponseStream(), encoding);
strResponse = objStreamReader.ReadToEnd();
objHttpWebResponse.Close();

objHttpWebRequest = null;

return strResponse;
}
}

Then
Call example.php file from your aspx file.
see below code how to call php file using asp.net

DataTable dt = ImportsContacts.GetDataTableFromArray(url +"/example.php", ddlmailoption.SelectedValue, txtusername.Text, txtpass.Text);//GContactsImport.GetGmailContacts(App_Name, txtusername.Text, txtpass.Text);
repgooglecontact.DataSource = dt;
repgooglecontact.DataBind();


I hope you will get good result and help to you.

Export Data into CSV file using Asp.net

How to use below code.

First create one default.aspx page and add below code into code behind file.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string[] mylist = new string[5]; //Declaring the string array;

//Assigning values to each element in the array
mylist[0] = "Hello";
mylist[1] = "how";
mylist[2] = "are";
mylist[3] = "you";
mylist[4] = "?";

//Creating a new List of type
List StringtoList = new List(mylist.Length);

//AddRange is a method of List objects that enables the conversion.
//We just need to pass the reference to the array.
StringtoList.AddRange(mylist);

CSVExporter.WriteToCSV(StringtoList);
}
}


Then create one CSVExporter.cs file into app_code and add below code into class file.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Text;

///

/// Summary description for CSVExporter
///
public class CSVExporter
{
public static void WriteToCSV(List personList)
{
string attachment = "attachment; filename=PersonList.csv";
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.AddHeader("content-disposition", attachment);
HttpContext.Current.Response.ContentType = "text/csv";
HttpContext.Current.Response.AddHeader("Pragma", "public");
WriteColumnName();
foreach (String person in personList)
{
WriteUserInfo(person);
}
HttpContext.Current.Response.End();
}

private static void WriteUserInfo(String person)
{
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.Append(person);
//AddComma(person.Name, stringBuilder);
//AddComma(person.Family, stringBuilder);
//AddComma(person.Age.ToString(), stringBuilder);
//AddComma(string.Format("{0:C2}", person.Salary), stringBuilder);
HttpContext.Current.Response.Write(stringBuilder.ToString());
HttpContext.Current.Response.Write(Environment.NewLine);
}

private static void AddComma(string value, StringBuilder stringBuilder)
{
stringBuilder.Append(value.Replace(',', ' '));
stringBuilder.Append(", ");
}

private static void WriteColumnName()
{
string columnNames = "Name, Family, Age, Salary";
HttpContext.Current.Response.Write(columnNames);
HttpContext.Current.Response.Write(Environment.NewLine);
}
}

Then press f5 and you will get result.
