When I try using the debugger to read myworksheet.Cells[row, col].DisplayFormat.Style.Font.Strikethrough I receive false. When I try using the debugger to read

问题 I have seen numerous posts on this subject here, but none seem to answer this issue directly. I want to control two instances of Powerpoint running on a second monitor.

问题 I've got a function which takes a word document and saves it in html format. I'd like to use the same function to work with any document type. I've tried using generics (I'm assumming the different doc APIs are the same) which fails due to the reason Jon Skeet pointed out.
