Yes.
The socket sends and receives messages - not data.
Messages a posted to a sychronized queue. The socket receiver packages the data and sends the message. The receiver gets a message, determines the type (file or chat) and then posts it to the appropriate place.
The file transfer itself has the highest impact but the chat has very low bandwidth needs so you set the chat to have a higher priority, such that waiting chat messages are always sent before file messages.
The file would be broken into chunks. perhaps 1meg or 100k.
There are variations on the above. The two socket situation could, with a bit of fuzziness, even said to be said to be a variation of this. In that case each socket is just acting like a queuing device.

What is the actual value of response on return from the call to CustomHttpClient.executeHttpPost? And why are you calling toString() on a String value?
Use the best guess
|
|
|
|
|
toString because un and pw are EditText
|
|
|
|
|
String response = null;
try {
response = CustomHttpClient.executeHttpPost("http://www.domain.com/Launcherloginaccount.php?username="+ userName +"&password="+ passWord +"", postParameters);
String res = response.toString();
response is already a String.

You really need to spend some more time writing down a detailed explanation of your problem. The listing of some XML on its own means absolutely nothing.

Hi,
i want to convert a cmyk type image into RGB Image.
if i use the below code the conversion happens but the image is not displaying properly.i can see block strike-through codes in my output image. any other way to convert CMYK to RGB.
java.util.Iterator<ImageReader> readers = ImageIO.getImageReadersByFormatName("JPEG");
ImageReader reader = null;
while(readers.hasNext()) {
reader = (ImageReader)readers.next();
if(reader.canReadRaster()) {
break;
}
}
ImageInputStream input = ImageIO.createImageInputStream(fromFile);
reader.setInput(input);
Raster raster = reader.readRaster(0, null);
BufferedImage bi = new BufferedImage(raster.getWidth(), raster.getHeight(),BufferedImage.TYPE_INT_RGB);
bi.getRaster().setRect(raster);
System.out.println("\n\n\n bi.getColorModel().getColorSpace().getType()\n\n "+bi.getColorModel().getColorSpace().getType());
int colorSpaceType = bi.getColorModel().getColorSpace().getType();
if( colorSpaceType == ColorSpace.TYPE_CMYK)
{
System.out.println("\n\n\n is CMYK image \n\n\n");
}
else if(colorSpaceType == ColorSpace.TYPE_RGB)
{
System.out.println("\n\n\n is RGB image \n\n\n");
ImageIO.write(bi, "JPEG", new File("d:\\hi.jpg"));
}

1. Pleas indent your code and put it between <pre> tags for readability, thus
public void stop1()
{
this.player.close();
}
2. Give proper details of your problem.

when i play an mp3 file then if i want to pause that song for some time then i can't i can only play and stop the song in this code
|
|
|
|

Rather than just repeating your original post, it would be helpful if you followed my previous suggestions. It is extremely difficult to read your code from that unformatted listing, and I cannot find a method anywhere that handles a Pause command.

I'm getting two values for my salt
This is my code
private static String getSalt() throws NoSuchAlgorithmException, NoSuchProviderException
{
SecureRandom sr = SecureRandom.getInstance("SHA1PRNG");
byte[] salt = new byte[8192];
sr.nextBytes(salt);
return salt.toString();
}
and when I save it in my database
my code
PS.setString(1, User);
PS.setString(2, getSalt());
PS.executeUpdate();
System.out.println(" Salt :"+getSalt());
I get different value..why?
I'm salting String asdf
Database value [B@2fc396df
Printed value [B@5199c9ac
|
|
|
|
|
salt.toString();
That doesn't do what you think it does. It prints the object reference not the contents.
|
|
|
|
|
By the way, your function createSalt() creates a new salt every time you call it!
When you want to compare the original value and the database value, you hat to write the salt into a variable, then set it to your object, write to database, then retrieve from the database.
