Closing applications outside of Access?

[ElEmEn]

I'm new to vba and am still learning. I have two questions about closing opened or potentially open documents, workbooks, and email messages. How do I write into my code to close a specified filepath (word doc or excel workbook) if open? Also, I have a code that exports data from Access into Word and then attaches the word doc to a new message in Outlook. I can't write into the code to close the Word app after attaching it to the message because I need to give the user time to complete their message and the word doc can't be closed until the message has been closed. How do I work around this?

If the document was not opened as a VBA object, the only way I know to close other application files is to terminate all instances of the application. Example:

' Author Guy Thomas http://computerperformance.co.uk/
' Version 2.7 - December 2010
' ------------------------ -------------------------------'
Option Explicit
Dim objWMIService, objProcess, colProcess
Dim strComputer, strProcessKill
strComputer = "."
strProcessKill = "'excel.exe'"

Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colProcess = objWMIService.ExecQuery ("Select * from Win32_Process Where Name = " & strProcessKill )
For Each objProcess in colProcess
objProcess.Terminate()
Next
'WSCript.Echo "Just killed process " & strProcessKill & " on " & strComputer
'WScript.Quit
'End of WMI Example of a Kill Process
