Update: Convertion from screen resolution to print resolution

Sorry Guys !! there is a small correction in the previous post all credit goes to  Rob Caplan one of the .NET gurus.in his own words

"The problem is neither an incompatibility between the EMFs in .Net and in Word (the EMFs are the same) nor a problem with the IDataObject interface itself, but an incompatibility between how WinForms presents an EMF its System.Windows.Forms.DataObject and how Word wants to read an EMF from its System.Windows.Forms.DataObject."
