Does anyone have a technique to determine if a pdf file is in use
(i.e. open in a pdf reader or editor)?
I know that if the file is in use, OUTPUT filename.pdf causes an
error in R:Base. Therefore, this can be used to determine if the
file is in use. However, if the file exists and is not in use,
OUTPUT filename.pdf deletes the contents of the file. Is there a
non-destructive way to check?
Thanks for any help with this.
Stephen,
Here's how ...
SET VAR vResult TEXT = NULL
PLUGIN GetFileLockStatus vResult|FileName.ext|CAN_READ_WRITE_EXCLUSIVE
RETURN
The resulting "vResult" variable will return the value of Yes, No, or File
does not exist.
So, in your case ...
If you would like to check the exclusive status, use the command as follows:
-- Simple Example
PLUGIN GetFileLockStatus vResult +
|D:\Documents\Customers.pdf +
|CAN_READ_WRITE_EXCLUSIVE
RETURN
In a multi-user environment, if you have the exclusive rights to read
and write, the vResult value will be "Yes", otherwise "No".
Complete list of third parameter:
CAN_READ - can read a shared file
CAN_WRITE - can write to a shared file
CAN_READ_WRITE - can read and write to a shared file
CAN_READ_EXCLUSIVE - can read from a file and not allow anyone else to read
CAN_WRITE_EXCLUSIVE - can write to a file and not allow anyone else to write
CAN_READ_WRITE_EXCLUSIVE - have exclusive access to a file. Nothing is shared
The result can be either of these: Yes|No|File does not exist.
That's all there is to it!
Very Best R:egards,
Razzak.
P.S. The GetFileLockStatus Plugin is a part of:
. R:BASE PluginPowerPack 9.5, Build: 9.5.5.30422 or higher ...
. R:BASE PluginPowerPack X (Version 10), Build: 10.0.1.20428 or higher ...
