I downloaded "Office 2010 Add-In: Icons Gallery" that is docx file with two backstage tabs that hold icons.
How can I extract the icons or use them in my application?
I use ImageMso quite frequently in my Excel development. Having stumbled on another post, I took it a step further and put a package together to visually search, extract and save icons from Microsoft Excel as a file or copy and paste (with alpha channel transparency) to another application. I also compiled a list of 8,899 distinct ImageMso names from the various sources. I hope others can find this useful.
