I got one small problem. The method suggested by u is working fine. But it is failing when user enters input, it is not taking of that situation. Application is simply exiting. I added WHEN_CHANGED also. Why because I am using that in input. That means am taking the input value for each and every character.
I think handler function take care of this situation. can u suggest me what should I do now??? On Wed, Mar 14, 2012 at 11:51 PM, Rajesh Kumar <[email protected]> wrote: > Great it works well.
