Well maybe this example is not with windows functions as they are API calls. But I can give an example using a .NET DLL Assembly!

1) Download SharpZipLib and install into the GAC (yes, has to be in the GAC. This is a MS decision!)

2) Add a script task

3) Edit the script

4) Add a reference to the DLL by right clicking on references and adding the reference

5) Initialise the object and use the assembly functions for Zip creation 🙂

We use package variables for the output dir and the name of the zip file (we add date info to this filename).

If you want, I possibly could write up a step-by-step article on how to achieve this in managed code.

Hope this makes sense 🙂
