Hi,

I am trying to copy/paste a structure to the clipboard the copy appears to work but the paste errors with "COMException crossed a native/managed boundary ErrorCode = -2147467259". The error occurs on the highlighted code line below. Is it possible to put a structure on the clipboard? If so how?

Thanks, Jeff
