We are using Linux. We open a pdf using shell command in livecode, we need back up the pdf for every 15 minutes. Is this possible by livecode.

Hi,
I think you have to use a "send in time" message.
Have a look at "send" and "pendingMessages" in LC dictonary.
Something like that:
Code: Select all
on startSavePdfPending
SavePdfPending
end startSavePdfPending
on SavePdfPending
-- Your save command
send "SavePdfPending" to me in 900 seconds
end SavePdfPending
--to stop
on stopSavePdfPending
doStopPending SavePdfPending
end stopSavePdfPending
on doStopPending pMessage
repeat for each line aLine in the pendingmessages
if pMessage is in item 1 of aLine then
cancel item 1 of aLine
end if
end repeat
end doStopPending
Best regards
Jean-Marc

Then how this possible.
Thanks,
Samjith.

Hi Samjith,
Here is a stack for example. I tested it on OSX but it should work on linux.
It use a pendingmessage called "SavePdfPending" that save the aera of grc "CadrePrint" to a pdf file.
This message is sent every 30 seconds (easier for test)
Fortunately you stop it with a clic on "StopSave".
I see the first page of pdf file is empty but I don't know yet how avoid this but I am sure someone have the answer
Best regards
Jean-Marc

I'm confused. LiveCode can't edit PDF files, so I think you are opening it in another app. Is that correct? f so, you can just use regular file commands to copy the existing file to another location. LiveCode needs to be running in the background to do that.
Code: Select all
put url "binfile:" & <path to pdf>" into url "binfile:" & <path to copy>"
If you are not editing the pdf in another app, what do you do with it in LiveCode?

What are the command line (shell) commands you are using to control the pdf?
In LiveCode, you would use something like Jean-Marc's timing script to execute the SavePDFPending handler every interval.
The handler would execute the shell command required to save the pdf in the required location, eg
Code: Select all
on SavePDFPending
get shell("/user/bin/thePDFexecutable ~/home/samjith/")
end SavePDFPending
whatever shell command you need depends on what your 3rd party controller application is.
