Hi all , In the below code am trying to upload file to a folder and if file is already there it will generatr a messagebox(wn32) where it will ask for overwrite but when i run my rails application on client machine this messagebox is not displaying on client machine
require 'dl' # button constantsBUTTONS_OK = 0 BUTTONS_OKCANCEL = 1 BUTTONS_ABORTRETRYIGNORE = 2 BUTTONS_YESNO = 4
CLICKED_CANCEL = 2 CLICKED_ABORT = 3 CLICKED_RETRY = 4 CLICKED_IGNORE = 5 CLICKED_YES = 6 CLICKED_NO = 7
class UploadController < ApplicationController def index render :file => 'app\views\upload\uploadfile.rhtml' end
def message_box(txt, title=APP_TITLE, buttons=BUTTONS_OK) user32 = DL.dlopen('user32') msgbox = user32['MessageBoxA', 'ILSSI'] r, rs = msgbox.call(0, txt, title, buttons) return r end
def uploadFile
name=DataFile.save1(params[:upload]) puts name $t=0
k =
File.open("d:/dm/aan.txt").each do |line| k << line.chomp end
puts k #puts line.size $s=k.size #puts $s
for i in 0..Integer($s)
if $L=(name.eql?(k[i]) == true)
response = message_box("Are you sure you want to OVERWRITE", "Proceed?", BUTTONS_YESNO) if response == CLICKED_YES
post = DataFile.save(params[:upload])
render :text => "File has been uploaded successfully" else
render :text => "File cann't successfully" end end end end end
How should i make this messagebox appear on client side
