New protocol specifications published on MSDN
Posted: (EET/GMT+2)
Just few days ago, Microsoft opened up many protocols and binary file formats that are related to Office applications, such as the Office application communication protocols and .DOC, .XLS and .PPT file format specifications.
The documentation is now available on MSDN, and the topic "Open Specifications" on the MSDN Library should be your starting point.
Enjoy!
