Can I use VBA to unzip a file using the native windows unzip feature?

I'm using Outlook 2003 & I want to use a macro to unzip a file attachment on a message. Can I use the bui开发者_高级运维lt-in zip file handling of windows in VBA to do this and if so, how? I'm running on Windows7 64 bit.

The answer at Windows built-in ZIP compression script-able? might have some solutions. If not I've successfully used the open source Info Zip DLLs to zip and unzip files. See Compression DLLs, OCXs, etc for links and sample code.
