Establish a new VB Project 2.    Reference Microsoft XML, version 2.0 or above 3. Create a button on a form Form1 CmdcreatexmlAnd cmdgetbinaryCode: Option Explicit

End Sub 4. Create a Word document Docinput.doc.
5. Save the document in the engineering directory 6.Run Program click Cmdcreatexmlbutton. An XML file Xmlouput.xml is established.
Click cmdgetbinarybutton to generate a Word document DOCOUTPUT.DOC.
As in the above method, you can also save any binary data as XML, and then regenerate the binary data that can be used for web transmissions, and so on, where you can use XMLHTTP.
