Cryptography

Another boring weekend with just some billiard with my friends. I missed goin' to club saturday night, oh well.
Oh yea, and 2 courses at University of Bucharest. , Distributed Programming and Cryptography(which turns out to be more than useful, right now)

Send sms in WM

If you need to send a SMS via an application in Windows Mobile .NET
try
{
SmsMessage sms = new SmsMessage()
{
Body = text
};
sms.To.Add(new Recipient(HQPhoneNo));
sms.RequestDeliveryReport = true;
sms.Send();

// MessageBox.Show("Message sent!");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}

Social network sites, and code to post stuff on it

It's pretty easy to post messages on Twitter, Facebook, MySpace etc. They rely on
a REST server, and basically you make a HttpConnection and send POST or GET messages to an URL, which you can find on API description(e.g. http://api.twitter.com/1/statuses/user_timeline.json)


Twitter allows basic authentication(but in future, will no longer be supported), even though it's better to use oAuth.
On Facebook I'm pretty sure that all you can use it's oAuth

Here's some code for Twitter

public static String viewMyTimeline( String user, String pass)
{
String url ="http://api.twitter.com/1/statuses/user_timeline.json";
String responseM ="";
HttpConnection conn;
try {
//prepare a connection for the twitter API update method
conn = (HttpConnection)Connector.open(url);

conn.setRequestMethod("GET");
byte[] credentialsBytes = (user +":" + pass).getBytes();
String encoded= Base64OutputStream.encodeAsString(credentialsBytes,0,credentialsBytes.length,false,false);

conn.setRequestProperty("Authorization", "Basic " + encoded);
conn.setRequestProperty("Content-Type", "application/xml; charset=utf-8");
System.out.println("respond message=" +conn.getResponseMessage());
System.out.println("-----------------------------" + conn.getResponseCode());
//get the response
InputStream is = conn.openInputStream();
int c;
StringBuffer buffer= new StringBuffer();
while ((c = is.read()) != -1)
{
buffer.append((char)c);
}
System.out.println("user=" + user);
System.out.println("pass=" + pass);
is.close();
responseM = buffer.toString();
System.out.println("response="+responseM);
conn.close();
}
catch (Exception ex)
{ System.out.println("" + ex.getMessage());

}
return responseM;
}


For facebook here's a snapshot to post a message

CEBOOK SET STATUS
public static String sendRequestStatus( String method,String api_key, String uid, String status, String secret ) {
HttpConnection conn = null;
String username =usernameF;
String password =passwordF ;
String message =status;

String response = null;
try {
Hashtable data = new Hashtable();
data.put("method", method);
data.put("v", "1.0");
data.put("call_id", "1");
data.put("api_key",api_key);
data.put("uid",uid);
data.put("status",status);
data.put("format", "JSON");
data.put("sig", getSignature(data,secret));

URLEncodedPostData encoder = new URLEncodedPostData(null, false);
Enumeration keysEnum = data.keys();
String coded="";
while (keysEnum.hasMoreElements()) {
String key = (String)keysEnum.nextElement();
String val = (String)data.get(key);
coded = key+val;
encoder.append(key, val);
}

conn = (HttpConnection)Connector.open("http://api.facebook.com/restserver.php?");
conn.setRequestMethod(HttpConnection.POST);
conn.setRequestProperty(HttpProtocolConstants.HEADER_CONTENT_TYPE, HttpProtocolConstants.CONTENT_TYPE_APPLICATION_X_WWW_FORM_URLENCODED);
conn.setRequestProperty(HttpProtocolConstants.HEADER_CONTENT_LENGTH, String.valueOf(encoder.getBytes().length));

OutputStream os = conn.openOutputStream();
os.write(encoder.getBytes());

if (conn.getResponseCode() == HttpConnection.HTTP_OK)
{
StringBuffer buffer = new StringBuffer();
InputStream is = conn.openInputStream();
int c;

while ((c = is.read()) != -1)
{
buffer.append((char)c);
}

is.close();
response = buffer.toString();
}
} catch (Exception e) {
} finally {
if (conn != null) {
try { conn.close(); }
catch (IOException e) {}
}
}


Enough of this, I bored you enough:))

Android Developers Challenge 2,

For those interested in Android development and also a challenge and to compete:

http://code.google.com/android/adc/

First http://developer.android.com/sdk/index.html

For eclipse install the plugin, and an example of Java Android Application

package com.example.helloandroid;

import android.app.Activity;
import android.graphics.Canvas;
import android.os.Bundle;
import android.widget.*;
import android.view.*;
import android.view.ViewGroup.LayoutParams;



public class HelloAndroid extends Activity {
/** Called when the activity is first created. */


LinearLayout mLinearLayout;



public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

// Create a LinearLayout in which to add the ImageView
mLinearLayout = new LinearLayout(this);

// Instantiate an ImageView and define its properties
ImageView i = new ImageView(this);
i.setImageResource(R.drawable.guitar2_bg);

i.setAdjustViewBounds(true); // set the ImageView bounds to match the Drawable's dimensions
i.setLayoutParams(new Gallery.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

// Add the ImageView to the layout and set the layout as the content view
mLinearLayout.addView(i);


setContentView(mLinearLayout);
}
}



Also a nice breakthrough new in this area:
