Hi BT? Thanks but my script is just a little sample of using MSAA in a
VBScript / Windoweyes app.
WMI is getting outside the native environment so I guess I can just use a
script variable to manage my text file's state. Actually, it works so I
don't need to do it but I feel "naked" not knowing the state of objects
before using them.
Thanks again and later.

Hi Rick,
You can go to this web site to get WMI events and the sample script
below alerts you about events. Just save the script and test it.

Set objReceivedEvent = objEvents.NextEvent

i = i+ 1

I don't see a property or method in the FileSystemObject for it, but
since you're managing the file yourself, you can always keep a
variable that holds the state and updates when you open/close the
file.
But if you're looking to know if something else has the file open, you
have a trickier situation on your hands I think. WMI services may
give you a way to do that, as might running a Net command as a
subprocess. The latter is probably too messy to be worth it though,
and off the top of my head, I don't know how to use WMI to find out if
a file is open by another process. But the answer to that problem,
figuring out if anything has a file open, is more a question of what
the OS will let you do than what Window-Eyes or the FileSystemObject
will let you do.

Hi: I have a file I created using the File System Object. I want to
check the File's state.
Is it opened, Closed or something else.
What Property or methods allow checking a file's state in VBS?
I haven't found anything yet Googling.
So, if you know anything about checking file state could you point me
in the right direction?
Thanks:
