When you call save method, many data contained in the Excel object is changed to generate the result file.
Why is this necessary?
I see that in a web environment after a save the use of this excel object is no more of intrest, but in a windows forms app, it could be.
The solution you provide in this thread is obvious, but why don’t do the save method this copying to leave the origin object intact?
Besides this the copying is unfortunately not working in VB.NET. I get a ‘System.ArgumentNullException’ in mscorlib.dll: ‘Key could not be null’ and don’t have any glue why.
PS: could you provide the version number to the download files (either msi or zip)?
