I should add that I use a timeout counter in the while loop in case the service app is not operating or functioning.

I normally do something like this. ShareRec.Filename := 'Whatever'; ShareRec.Command := 2; While ShareRec.Command <> 0 do Sleep(10); The service application detects the command = 2, does something with the filename, and sets command to 0 when finished. The While loop usually only executes once so there is no delay for the user.. You could run this in a thread if it was going to take a while. I didn't know about NewInstance to allocate the object where you need it. There is still an issue with strings and pointers inside the object. Simple records work well enough for me. Ross.
