Hi all,

I have two dropdowns say State and District. In first page, I select a state based on which District will be loaded. Now I select State as TamilNadu and District Chennai. Upon clicking it takes to second page as well as it stores it in DB. Now second page is for edit. I click an edit button. It takes me back to first page. Now I want to load all the values of State and i want TamilNadu as a highlighted one. similarly for District, all other values must be loaded and Chennai must be highlighted.

I load values using the following call

I am able to fetch the selected option. But I just get struck up as I want to make that option as the first one which doing Edit operation.

The following code reads a csv file and displays that as table. I would like to add 3 buttons say Start, stop and insert. On clicking Start the table should be generated. On clicking reset, the table should be cleared.



In the above code, where should I add buttons and how should I change the code to implement what I intend to do.
Any help would be greatly appreciated.

Hi all,
I am new to the concept of singleton. I have a text file and whenever i update this file, producer should be notified and many consumers say 5 threads try to access this. Only one thread should be able to read this file and that should write to the another text file. When second thread tries to access the same file at the same time, it should be said that thread 1 is accessing.


Please help me on how to approach this kind of scenario.
It would be easy for me to understand if some one can code it.
Thanks in advance
