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??
