Hello again.
Weird behavior in my app.
While writing to disk using this subroutine:
on write_to_file(this_data, target_file, append_data) -- one of Apple's essentail subroutines sample codes
try
set the target_file to the target_file as text
set the open_target_file to ¬
open for access file target_file with write permission
if append_data is false then ¬
set eof of the open_target_file to 0
write this_data to the open_target_file as «class utf8» starting at eof
close access the open_target_file
return true
on error
try
close access file target_file
end try
return false
end try
end write_to_file
the app plays the system sound on each write (it does several hundred writes on a typical save), even though I have user interface sounds disabled in the sound prefs dialog.
This is disastrous, since the program is meant to be used on an internet radio broadcast host, and the sounds will be broadcast. It's a definite deal killer. I've tested this on 3 different machines, an old Pismo, a 1GZ 17" pbook, and a mac mini with a core duo. The first two are running tiger, the mini is running leopard. The two pbooks are using an xcode 2.4.1
build, the mini a leopard build.
Is there something I should know about disk writes? or progress bars?
Here's my save dialog subroutine:
on DisplaySaveStatus(mystatus, myprogress, startprogress)
if startprogress = "go" then
display panel window "status" attached to window "main"
set content of text field 1 of window "status" to mystatus
set content of text field 2 of window "status" to myprogress
start progress indicator "progress" of window "status"
else
if startprogress = "stop" then
set content of text field 1 of window "status" to mystatus
set content of text field 2 of window "status" to myprogress
close panel window "status"
stop progress indicator "progress" of window "status"
end if
end if
