check if visio file is open

[jes]

hi,

i have a table with a delete & open button. onclick of open, the visio file
opens in visio and onclick of delete the visio file gets deleted from the
file system. One problem, if the file is already open by another user how do
check for this and then return an errormsg to the user.
now im getting:
System.Runtime.InteropServices.COMException: This file is open for
modifications in another instance of Visio.

thanks

Perhaps you should test for its lock file.
For example, if I open a Visio document cbvtext.vsd, then a hidden file
called ~$$cbvtest.~vsd is created in the same folder. It disappears when
the file is closed.
