Timbuktu example scripts include the following snippet:
tell application "Timbuktu Pro"
-- snipped code
set theStatus to ""
try
set theStatus to (transfer remoteItem to theDestDir with replacing)
on error errorMessage
set ErrorsOccurred to true
end try
repeat while exists theStatus
try
if (transfer status of theStatus is finished with errors) then
set ErrorsOccurred to true
close theStatus
exit repeat
end if
on error
-- assume the window went away before the IF was evaluated,
-- this happens sometimes
exit repeat
end try
end repeat
-- more snipped code
end tell
I don't think the repeat loop here is a "hard" loop as the "if" after the
second "try" is done by Timbuktu when it has the time.
I have not tried this technique on FM having found that the following
un-elegant shot-gun approached worked:
if not ErrorsOccurred then
tell application "FileMaker Pro"
open file "hd:acc cust"
try
considering application responses
-- with timeout of 600 seconds -- (1)
do script "export cust"
-- end timeout
end considering
on error errorMessage
set ErrorsOccurred to true
end try
if not ErrorsOccurred then
with timeout of 600 seconds -- (2)
open file "hd:acc cust sum"
end timeout
try
considering application responses
do script "export cust month"
end considering
on error errorMessage
set ErrorsOccurred to true
end try
etc...
The timeout (2) was necessary because control is return immediately after
the "do script..." above and the "open file "hd:acc cust sum"" timed out
(because FM did not return control until it completed the script and started
the "open").
I hope this helps,
