>Thank you, Dragan. Most probably, I'll go with the Tx Control, even though it seems like an overkill for what I need. I was hoping for a no UI, straight RTF to HTML converter that I could invoke and execute behind the scenes. I'll look more into the Tx control; perhaps I could make better use of its editing functionality, as well.

I'm using it without any GUI for this conversion. I have added it to a form, though, for other cases when I may use it (but then didn't), and I of course had to subclass it, but beyond that point it's rather simple.

Here's the extract from the code:

* check for docx
	lnH=Fopen(lcFromFile,10)
	lcHeader=Fread(lnH, 2)
	Fclose(lnH)
* signature of Phil Katz means this is a zip, i.e. a zipped directory structure of xml files, i.e. a docx

*!*	Constant  Description
*!*	1 - ANSI text  Text in Windows ANSI format (an end of a paragraph is marked with the control characters 13 and 10).
*!*	2 - TX text  Text in ANSI format (an end of a paragraph is marked only with the control character 10).
*!*	3 - TX  Text including formatting attributes in the internal Text Control format. Text is stored in ANSI.
*!*	4 - HTML  HTML format (Hypertext Markup Language).
*!*	5 - RTF  RTF format (Rich Text Format).
*!*	6 - Unicode text  Text in Windows Unicode format (an end of a paragraph is marked with the control characters 13 and 10).
*!*	7 - TX text  Text in Unicode format (an end of a paragraph is marked only with the control character 10).
*!*	8 - TX  Text including formatting attributes in the internal Text Control format. Text is stored in Unicode.
*!*	9 - Microsoft Word 97-2003  Microsoft Word 97-2003 format (*.doc).
*!*	10 - XML  XML format (Extensible Markup Language).
*!*	11 - CSS  CSS format (Cascading Style Sheet).
*!*	12 - Adobe PDF
*!*	13 - Microsoft Word  Microsoft Word format (*.docx).

	lnType=Icase(lcHeader="PK", 13, 9)

	loTx.Load(lcFromFile, 0, lnType)
	lnRet=loTx.Save(tcTargetFile, 0, 12)
	This.nDocCnt = This.nDocCnt + 1
	If lnRet=0
		This.oLog.Log("PDF maker reports error ")
	Endif
	loTx.ResetContents()
	Return lnRet>0

You'd have different last parameters in .save() and .load(), but that's it.
