After discovering on superuser that there is no current way to add syntax highlighting to the Windows 7 preview pane, I figured if someone else hasn't done it yet then I'll go ahead and do it myself.
Is there an API or SDK available for Windows 7 that exposes the preview pane in explorer to customization? If so, what is it and how do you think is the most elegant way to accomplish this? I would like it to read the syntax highlighting options from Visual Studio to get the users favorite colors and code theme settings.
You must check the Preview Handler, you can download an example from here. The Preview Handler is used to display a file preview inside the Windows Explorer preview pane or other preview handler hosts.
