问题
I have created an .xlsx file using the OpenXML framework and I am embedding it into a PowerPoint slide (also created using OpenXML) the problem is that I need a placeholder image for the OleObject the Excel sits in on the PowerPoint slide - i can use a standard placeholder, but this looks bad.
So I was hoping (most likely using Interop) to find a way of opening the .xlsx file and exporting the relevant cells as a bitmap (.jpg or .png ideally) which I can then feed into my OleObject as the placeholder image.
I came across this: http://csharp.net-informations.com/excel/csharp-excel-chart-export.htm
Which does what I am trying to do, but on a Chart object, so if someone knows a way to export cells (ideally a selection, rather than the whole worksheet) to a bitmap, that would be great!
Thanks,
Mike

An Excel Range object has a CopyPicture method that does what you're looking for.
JP has a VBA example posted that you should give you what you need.
