Hello,

I have a Result printing module in which i have a form in which i have a textbox in which the user enters a roll no of the student whose result is to be printed and clicks on print button.

Now, when the user clicks on the print button i will check thru my database if the result is already printed if the result is printed i will show a pop up to the user saying....This Result is already printed would u like to re print it..? And then 2 boxes Yes No...if the user clicks on Yes again print operation will be carrried out if the user clicks on No then the print operation is cancelled....

May i know how can i do this...? I guess we have to use call back...but i have not yet tried this please help me...do u have any simple method to achieve this??

Thanks!

Best Regards,
Rohan Laghate

0	As this is a web application so I would suggest to retrieve the value of the record whether it has been printed or not as soon as the page loads (store this into the JavaScript variable like below (_documentPrinted is your variable that holds the boolean value from the database). var IsPrinted = '<%= _documentPrinted %>'; On click of the Print button, call a JavaScript function that will check for the IsPrinted variable, if it is true then will fire the confirm method of JavaScript by passing the string "The result is already printed ....". If user clicks OK, it returns true and you will check for that value and fire the window.print() method. if (IsPrinted) { var v = confirm('The result is already printed, do you ....'); if (v) { winow.print(); } } Hope this approach will give you some idea and you will be able to do this yourself.

if (IsPrinted)

  var v = confirm('The result is already printed, do you ....');

  if (v)

  { 

    winow.print();

  }

}
