You can use the macro recorder to find out what methods or properties you need to accomplish a task in Word. The macro recorder is a tool that translates your actions into Visual Basic instructions. For example, if you turn on the macro recorder and open a document named Examples.doc, the macro recorder records an instruction similar to the following.
Documents.Open FileName:="Examples.doc", _
ConfirmConversions:=False, ReadOnly:= _
False, AddToRecentFiles:=False, _
PasswordDocument:="", PasswordTemplate:="", _
Revert:=False, WritePasswordDocument:="", _
WritePasswordTemplate:="", _
Format:=wdOpenFormatAuto
The Documents property returns the Documents collection and the Open method opens the specified file name. When you're first learning Visual Basic, using the macro recorder will help you learn which properties and methods you need to use to accomplish a task.
