>The api is documented though under Using the Task Scheduler in the Platform SDK. There several C++ examples that demonstrate how to use the classes and I have that all working with a wrapper DLL.

I did get it working using the IID

ox=CREATEOBJECTEX("{148BD520-A2AB-11CE-B11F-00AA00530503}",'','{148BD524-A2AB-11CE-B11F-00AA00530503}')

and was able to fiddle with it a little. I still think you took the better route, just sucking mstask.h into a wrapper DLL. Much less of a pain, I believe, saves you from having to dig through the IDL looking for IIDs.
