check if Win32OLE still available

[Reinhart Viane]

[Note: parts of this message were removed to make it a legal post.]

In ruby i use these commands:



application = WIN32OLE.new('MSProject.Application')

application.visible = TRUE

application.FileOpen(filepath)

project = application.ActiveProject



now if the user closes MS Project, any call to application.function returns:

The RPC server is unavailable.



Which off course, I think, is logic.

How do I test if the application is still available?



Regards and thx

call some method on it, perhaps?

Thx again!

When you call a method after the application has been closed, does it
throw an exception? If so, you could catch the exception and check
the error to see if it's a result of the closing of the app.

Hello,

I'm getting back on this.
I do receive an error, however, it seems I cannot catch it.
It does not give me back empty or nil. Maybe there is another method to
catch that error?

What is the error you received?

It does not give me back empty or nil. Maybe there is another method to
catch that error?

How about catching WIN32OLERuntimeError?

begin
...(your script)
catch WIN32OLERuntimeError
...(catching error)
end

This is the error:

Error: #<WIN32OLERuntimeError: unknown property or method `ActiveSelection'
HRESULT error code:0x800706ba
The RPC server is unavailable.

Where can I find more info on that catching?
Is it possible to use in a if clause (to let the script continue or go to
another script)?

Thx already!

No. You must use begin rescue end to catch WIN32OLERuntimeError exception.
If you want to let the script continue, write the script like following.

is_ok = true
begin
obj.ActiveSelection
rescue WIN32OLERuntimeError
is_ok = false
end
if (is_ok)
...
continue script non exception occurred.
else
...
continue script when WIN32OLERuntimeError occurred.
end
