' To Do:
' +1. error output on bad input to this file. And commit.
' +1b. Active X error msg when trying to convert normal *.doc: only when windows scripting is on and Word not installed.
' +1c. Make docx accepted by default as well. Changed WordPlugin.
' 2. Try converting from other office types (xlsx, pptx) to html. They may use other constants for conversion filetypes
' 3. gsConvert.pl's any_to_txt can be implemented for docx by getting all the text contents. Use a separate subroutine for this. Or use wdFormatUnicodeText as outputformat.
' 4. Try out this script on Windows 7 to see whether WSH is active by default, as it is on XP and Vista.
' 5. What kind of error occurs if any when user tries to convert docx on a machine with an old version of Word (pre-docx/pre-Word 2007)?
' 6. Ask Dr Bainbridge whether this script can or shouldn't replace word2html, since this can launch all versions of word (not just 2007) I think. 
' Unless some commands have changed? Including for other Office apps, in which case word2html would remain the correct program to use for those cases.


' gsConvert.pl expects error output to go to the console's STDERR 
' for which we need to launch this vbs with "CScript //Nologo" '(cannot use WScript if using StdErr
' and //Nologo is needed to repress Microsoft logo text output which messes up error reporting)
' http://www.devguru.com/technologies/wsh/quickref/wscript_StdErr.html
Dim objStdErr, args
Set objStdErr = WScript.StdErr

args = WScript.Arguments.Count
If args < 2 then
  'WScript.Echo Usage: args.vbs argument [input docx path] [output html path]
  objStdErr.Write ("ERROR. Usage: CScript //Nologo " & WScript.ScriptName & " [input office doc path] [output html path]" & vbCrLf)
  WScript.Quit
end If

' Now run the conversion subroutine
Doc2HTML WScript.Arguments.Item(0),WScript.Arguments.Item(1)
	' In terminal, run as: > docx2html.vbs C:\fullpath\to\input.docx C:\fullpath\to\output.html
	' In terminal, run as: > CScript //Nologo docx2html.vbs C:\fullpath\to\input.docx C:\fullpath\to\output.html
	' if you want echoed error output to go to console (instead of creating a popup) and to avoid 2 lines of MS logo.
	' Will be using WScript.StdErr object to make error output go to stderr of CScript console (can't launch with WScript).

Sub Doc2HTML( inFile, outHTML )
' This subroutine opens a Word document,
' then saves it as HTML, and closes Word.
' If the HTML file exists, it is overwritten.
' If Word was already active, the subroutine
' will leave the other document(s) alone and
' close only its "own" document.
