I am trying to send attachments to the receiver.
Although,it doesn't show any error ,I am not receiving the attachment.

When you upload a file you need to move it from temporary directory to a directory of the server, so you can store the file, use move_uploaded_file(): http://php.net/manual/en/function.move-uploaded-file.php
And then change this line, it seems wrong:

$mail->AddAttachment('file:///H:/ha.txt','a.txt');

with:

$mail->AddAttachment('h:/server_directory/files/ha.txt','a.txt');

Thanks this worked.
But what if I want to accept the file in the form itself by the user?
As in upload it

It is always the same, just make sure PHP can't be executed in destination directory and that is not directly accessible to web, so no one can upload a script and use it to hack your server. You can do that by placing a .htaccess file in the directory that will store files and writing just this:

order deny,allow
deny from all
php_flag engine off

Usually Windows doesn't allow filename starting with a dot, if you are uploading to a remote directory, just use ftp to rename the file. Bye :)

Note: you should also check the mime of the files and run an antivirus on the server to check the files submitted.

To who voted against my previous reply: explain me what I did wrong, at least I can learn ;D
