Custom client app - need ability to control where documents are saved

Okay SO. I need some guidance. I apologize for the length of this post, but I need to provide some details:

I've got someone who is interested in me to do a small project for them. The application in general is a fairly straightforward employee record keeping / documentation app, but it makes pretty heavy use templated Word and Lotus documents. The idea is you select the employee “event” such as commendation, promotion, discipline, etc., and it loads the appropriate template doc and you fill it in from there, and later you can select an employee, view all the “events,” and view the individual documents associated with each one.

Thus, the app must know where the .docs are saved when the user is done.

The client actually has a v1 of this app (it doesn’t do any management of the files or anything, just launches Word/Lotus with the document you wanted to view in a new instance, presumably via a system() call.) We’ve not gotten into a detailed requirements phase, but the client and I agree that for this to really work, some kind of control over where the user saves the .doc’s to is going to be critical , because otherwise the app provides them with the new copy of the template doc, they "Save as" somewhere else, and the app is pointing to the blank copy it provided th开发者_如何学Pythonem with.

Obviously, I can’t think of a way to achieve “Save as” restriction/control in any way via just launching a new instance of Word. The client has the idea of an embedded Word/Lotus instance in the app with the template doc when you choose one, but I’ve few reservations with that:

• I’ve dug around online and I’ve read that whichever version of Word I borrow MSWORD.OLB from will be the one the end user would require?
• I’ve tried to do the MSDN example of embedding a Word doc from here, but as I’ve come to get used to, the MSDN example doesn’t even compile.
• Even if I CAN figure out how to embed a .doc file into their application, I don’t know that I could control the use of “Save as…”
• All of this STILL hasn’t touched on Lotus (!)

So… instinctively, I feel the embedded Word/Lotus thing has to be more work than it’s worth in the end.

So I’ve had a few other ideas brewing around.

1. One is looking into using Office XML (and if there’s a lotus equivalent), and get the user’s “inputs” separately and generate the document on the fly each time. I’m not particularly thrilled with that idea, but I think it COULD work, provided I just use old features to try and stay far backwards compatible.
2. Get user’s “inputs” separately and generate a document in HTML. Meh. Works, very cross platform and easily parsed and understood, but not good if you want to be able to email it to someone (who emails a .html? Works, yes, very unconventional which to the average user will throw them off) and even worse if you need to email it to someone for revisions…
3. Perhaps some kind of editable PDF? I know there are PDF libraries out there, and the more I stew on it, the more this sounds like the best option, though I’ve not done much work with PDFs and I don’t know how easily embeddable they are / what options one has when creating them. I know they can be save-disabled, I’ve had that with my bloody state taxes before.

I need some input here. Here’s the TLDR questions:

1. Is launching a new instance of Word for each .doc as bad as I feel, given user can “Save as” document wherever and then application is left pointing to a blank document?
2. Is trying to support embedded Word as big of a trouble as I feel like it is / more work than it’s worth / likely to cause problems with supporting multiple versions of Word? (Forward compatibility as well as currently released versions?)
3. What are thoughts on the PDF plan?
4. Any other good ideas?

---

Word does allow for programming some "Save" and "Save As" control via its object model. Any subroutines coded in VBA and placed into your Word template will be copied into all documents generated from that template. Additionally, most menu and Ribbon commands can be intercepted by creating a module containing subroutines named for the intercepted commands. So, for example, if a module contains a sub named FileSaveAs(), any code in that sub will be executed instead of the standard File|Save As command. Lastly, this code will replace Save As commands executed via keystroke, toolbar, menu, or Ribbon.

The code below will launch a dialog box to a predetermined path whenever a "Save" or "Save As" command is executed:

Sub FileSave()
ControlSaveLocation
End Sub

Sub FileSaveAs()
ControlSaveLocation
End Sub

Sub ControlSaveLocation()
Dim Directory As String
Directory = "C:\Documents\"
With Application.Dialogs(wdDialogFileSaveAs)
    .Name = Directory
    .Show
End With
End Sub

Hope this helps.
