SaveAs button click

**kasiram.p@gmail.com** · 07-06-2010, 07:15 AM

And in my code , it is working fine, but when i click save as button, save as dialog pops up and if i give an already existing file name, it throws an error dialog as "File already exists, do you want to replace?' and if i click CANCEL, the save as dialog again pops up and if i give the same file name which is already existing, it saves, without giving error dialog, that 'File name already exist?'
