Word Office Add in: Best way to handle editable ranges inside a non editable portion of a Word document?

Question

Hi,

I have an old Word template project written in VBA that was used to insert in the rows of a table in a Word document

1. new blocks of document.
2. old blocks of document saved on a database (Access)

Each block has some parts that are editable and some that are not. The table in non editable.

I used to solve the problem using Content Controls.

I had:

• the whole table was wrapped by a wdContentControlGroup, with properties:
  • LockContentControl = true
    • LockContents = true
• each block had one or more wdContentControlRichText, with properties:
  • LockContentControl = true
    • LockContents = false

Every time the user decided to insert a new block the wdContentControlGroup property LockContents was first changed to false and then to true again.

Can I do the same with an Office Word Add-In? There are better way to accomplish the work? There is a way to render non editable ranges of a document?

I used to save each edited block in its own Word file. When the user wanted to insert a specific block, I retrieved the file, the I copied the range and inserted it in the desidered row of the document.

There is another, better way to accomplish this? Can I save only the range block? In which code? How to handle it?

(I'll probably abandon Access because I want the back end of the DB to be both local or on line.)

Thanks for you advice, I'm completely new with the Office Add-Ins technology.
