    Look at the API doc for the classes you are using and see it there are any methods to call that will do what you want. Then call those methods when you want them to be executed.

    Call that method before calling the setVisible() method for the frame.

    Default Re: Button disable

    Please Edit your post and wrap your code with[code=java]<YOUR CODE HERE>[/code] to get highlighting

    You can call methods on an object any time after you have created an instance of it.
    Try adding the call to the method right after an instance is created:
    b1 = new ....
    b1.setEnabled(false);

    i tried it giving error
    Please copy and paste here the full text of the error message.
    If you don't understand my answer, don't ignore it, ask a question.

    Thanx Norm

    Actually in Netbeans we usually cannot edit the code that is written in the initComponents(); method so to add that code before any click is not possible .. but i found that we can edit the property in the property window..... there i did and found my solution
    Thnx for your support and valuable time
