Quick and Easy Code <input type = "text" onkeypress = "return (event.charCode !=8 && event.charCode ==0 || (event.charCode > = 48 && event.charCode <= 57))" /> This will permit usage of numbers and backspace only. If you need decimal part too, use this code fragment <input type = "text" onkeypress = "return (event.charCode !=8 && event.charCode ==0 || ( event.charCode == 46 || (event.charCode > = 48 && event.charCode <= 57)))" />

The root account is disabled by default in Ubuntu, so there is no root password, that's why  su  fails with an authentication error. type sudo su and then enter the password

This is what I did. Go to Window --> Show View --> Project Explorer Then right click on the project name that you want to delete and Click Delete. In the dialogue box, check 'Delete Project Contents on disk' It worked. I was able to create the project with the same name again.

select at least one folder to import as project Just delete the ".project" file in your project folder (it's hidden on Linux, use "ls -a" to show), then from Eclipse, choose Create Android Project from existing source. It worked for me.. Thats it.Cheerzz.. /eclipse-workspace/.metadata/.plugins/org.eclipse.core.resources now go to .projects folder and delete already existed project with same name

Turns out you can't use the  root  user in 5.7 anymore without becoming a sudoer. That means you can't just run  mysql -u root  anymore and have to do  sudo mysql -u root  instead. That also means that it will no longer work if you're using the  root  user in a GUI (or supposedly any non-command line application). To make it work you'll have to create a new user with the required privileges and use that instead. Login to MySQL sudo mysql -p -u root then enter the password entered during mysql installation. CREATE USER CREATE USER 'admin'@'%' IDENTIFIED BY 'your_password'; GRANT ALL PRIVILEGES GRANT ALL PRIVILEGES ON *.* TO 'admin'@'%' WITH GRANT OPTION;
