Today I was asked by my friend about how to create the Word document that the odd pages and even pages have different header. I searched the method from the internet, anyway, she can do it before I know haha.
The instruction about how to create the different odd-and-even header
After creating the new document, go to Insert Tab->Header.
My friend, Net, just told me how to insert the file as an object to the document. It's also possible to do the same method in other office applications.
Go to Insert->Object->Object...
You can Create the new one or insert your exist file.
For my case, I inserted my exist file named DropDownList Excel file.
Tick Display as Icon if you would like to show your file as the icon. You can also change your icon to be other image.
