> ConvertToWordDoc    

This function uses Word Automation to convert a file to a Word Document Format. Theoretically, any document that is a) openable via Word and b) saveable as a Word document can be used by this function.

The process is completely transparent to the user: If Word is not already open, there will be no visible indication that the application is performing any processing. If Word is already open, the file is opened hidden and saved without prompt, and then closed, leaving the Word application open with the previously active document showing.

The function uses late binding of the Word Object Model and should be consistent throughout most versions. Created and tested using Access 2003 and Word 2007, and although not yet tested the Automation is expected to work for Word 2000 and newer.

Future Enhancements: The function is missing at least two possible validation checks:

  1. If there is already a document open that has the same name as the Output File, the procedure may fail. This condition has not been tested. It can be verified during the same loop that checks for the Input File already being open.
  2. If the Output File already exists and the user instructs to overwrite it, the existing file is deleted immediately before saving the new file. There is currently no validation to ensure that the existing file deletion was successful.

' REV 1.0: Initial Release
' Converts an RTF (or any other word-openable file) to a word document
' Access 2002+ (or an InStrRev replacement for earlier versions)
' Requires MS Word installed on the machine, or
'   to run Word from an application server, comment out the GetObject() lines
'   and pass the second argument of the CreateObject() function as the server name
' Operates by creating an instance of Word, opening the file and saving
'   as a word doc.
' Returns True on success, False on error
'   sFileIn: Full path to the file to be converted to .doc
'   sFileOut: Full path of the converted file
'   bPromptOverwrite: True to prompt the overwriting of an existing FileOut
'   bDeleteSourceFile: True to delete the source file after converting
