I'm writing a program that writes the Summary Information in the Properties dialog box for some files that I've created. In other words, when you right click on a file, click properties, and go to the summary tab, the fields such as: Title, Author, Category, and Comments should have some text written in them. I've found some code through internet searches on how to write to Title, Author, and Comments, but not the Category field. Anybody know why? It seems like there are property IDs for every field except the Category field. I'm programming with Microsoft Visual C++ 6.0.
