Using selection and ranges in word interop

Question

How do ranges and selections work?

If you insert something at the top of the page through a range, is that overridden by inserting something with selection? Does selection affect ranges?

I'm having a problem where I do inserts in this order, but the InlineShapes show up at the top of the document above the Range.Inserts. Also, the Selection.InsertBefore gets replaced by the InlineShapes.

I would like my range insert to appear above each picture, like a heading. How can this be done?

Selection.InsertBefore
**Loop**
     Range.InsertParagraphAfter
     Selection.InlineShapes.AddPicture
**End Loop** 

I've asked a question like this three times now with no responses. Anything would help!

EDIT:

I'm a step closer. Now, when I add my InlineShapes, I use Content.InlineShapes.AddPicture(FileName: x, range: y). Now the pictures are showing up in between paragraphs, but they are in the first cell of a table I add to the document before adding the picture. I add the table with with a collapsed range.

And for reference, the questions referred to (I guess) are:

• Using interop.word ranges

... which all now have been answered :)

You ask multiple questions in this post however - first:

How do ranges and selections work?

Actually, the documentation covers this quite well:

A range:

"Represents a contiguous area in a document.

Each Range object is defined by a starting and ending character position. Similar to the way bookmarks are used in a document, Range objects are used to identify specific portions of a document..."

Reference: http://msdn.microsoft.com/en-us/library/microsoft.office.interop.word.range(v=office.14).aspx.

If you insert something at the top of the page through a range, is that overridden by inserting something with selection?

It can be. This depends on what has been selected. If you select something that intersects with the range of the content you just inserted and changes the content, then you will make changes to the content of the range.

To understand this completely, I will recommend that you read about:

• The Selection Interface
• The Range Interface

Does selection affect ranges?

It depends. The documentation states:

Range objects are independent of the selection.

Reference: http://msdn.microsoft.com/en-us/library/microsoft.office.interop.word.range(v=office.14).aspx

... so if you just do a simple selection in order to, e.g., read content or copy content to the clipboard, nothing would change. However, if you use the selection to change content, of course this would affect the content pointed to by the ranges. In continuation of this you should note that MS recommends using Range objects for document manipulation:

Because Range objects share many of the same methods and properties as Selection objects, using Range objects is preferable for manipulating a document when there isn't a reason to physically change the current selection.

Reference: http://msdn.microsoft.com/en-us/library/microsoft.office.interop.word.selection.aspx

And finally, you ask:

I'm having a problem where I do inserts in this order, but the InlineShapes show up at the top of the document above the Range.Inserts. Also, the Selection.InsertBefore gets replaced by the InlineShapes.

I would like my range insert to appear above each picture, like a heading. How can this be done?
