I am sorry to say that both OLE and it's more recent cousin COM are Windows only techniques; neither can be used on the AS400. Your best bet would be to concentrate of patching HWPF I think as it will run on any java virtual machine. I have not investigated the problem myself but it seems as though the Range class is unable to determine the bounds of the text correctly and think that the start and end points either of the existsing text or the replacement text have become corrupted. There is a method called something like sanityCheck() and that seems to be where the confusion arises. I think that if you could fix this, then you may be able to run with the first chunk of code I posted; the bit that gets the overall Range object for the document, from that all of the Paragraph objects and then steps through each of these and iterates through their CharacterRun(s) to perform the replacement operation.
For a couple of days now, I have been meaning to mention a thought I had about the problem you encountered using CharacterRun(s) as opposed to Paragraph(s) in the search and replace operation; if you remember, you had multiple word search terms and they were split between CharacterRun instances. All you would need to do IMO is to change the logic of the search and replace code slightly. If it finds the first word of the search term in a CharacterUn, then get the following character run and test to see if it contains the second or subsequent words in the search term. If it does then you can simply replace each part of the search term as appropriate. This should hold true even if you find that the search trem is split over many CharacterRun(s) I think. As always, if you need any help, just drop a message onto the list; that goes for devloping as well as using HWPF. Yours Mark B karthik-33 wrote: > > Thanks Mark.
