I did some Windows Script Host programming recently and I was pleasantly surprised by its power, features and flexibility. One thing that I couldn't accomplish was accessing the clipboard from WSH. Digging the internet I found some solutions like this one based on Internet Explorer Automation. There are several problems with this approach as you can read in my article about Internet Explorer Automation: What's wrong with Internet Explorer Automation?
My solution for scripting the clipboard content in WSH is a regular COM object created with VC++ and ATL.
Download full source code and compiled DLL: WSH_clipboard.zip
To install the COM object run register.bat
I found scripting the clipboard useful enough to add this feature to the next release of Twebst Web Automation Library.
