    Re: Invisible Choicegroup

    Do you mean you want it to no longer be shown? How about simply deleting it from the Form then?

    Thank you dear Bogdan,

    Actually, I don't want to remove it, I want usser can't change it. This choice group show a question and 4 answer. I want after selecting one question by usser, he/she can't change his/her answer.
    In microsoft visual studio C++ or C# or Delphi, we can use visibility method (for example: Chiocegroup.visibility = true or false I want to know how can I use visibility in java.

    Also I have another question. In C we can wite for code as:
    ---------------------
    int i, j;
    for( i=1, j=7; i <= 5, j<=12; i++, j++)
    question[i] = readRecordID(j);
    ---------------------
    but in java when i write this code, ther are some errors are showed to me. why?

    Re: Invisible Choicegroup

    You could read the selected value when the choice is made, then remove the ChoiceGroup.

    Your "for" loop... the middle term must be a boolean expression.

    Code:
    i <= 5, j <= 12
    This is not a boolean expression. Replace the "," with "&&" or "||".

    (The same is true in C... your C compiler is just ignoring one of these two comparisons.)
