My code

        format 29@ "file" 
        format 28@ "link" 47 47 47 47
        call @Download 2 29@ 28@ 
        0AF0: read_int_from_ini_file 0@ section "AuthKey" key "Key" store_to 3@
        0B00: delete_file 0@
        if and
        0C18: 3@ = in_string 2@ find 3@
        then
            format 2@ "Input the access code"
            31@ = 1
            Dialog.SetControlText(1@, 3, 2@)
            Dialog.SetVisible(1@, false)
            print "~y~Access ~g~Granted!" time 1500
        else print "~y~Access ~r~Denied!" time 1500
        end    

so this does is download a file then read the key then delete it, after it reads It checks if in the edit box of dialog is there the key there.
but it just accepts the till 11 in this code.

Is there any opcode or thing to check string length?
