Adding version information automatically in Microsoft Word document

gistfile1.txt

The following will provide an automatic way of adding version information into a Microsoft Word document using an external text file. This is an ideal way in versioning documents using external controls such as a build script. The script can update external version file and then create a PDF of the document. Thereby, creating a "build" of the Word document.

1. Add a version.txt file in the same folder as your document. This file will contain a single line with the version information (e.g. 1.0.0)
2. Open the Word document and Add an IncludeText Quick Part.
3. Reveal the field codes by typing ALT-F9
4. Position the cursor after "{ INCLUDETEXT" just before the closing " }" tag.
5. Go to Quick Part and insert a FileName field and tick the "Add path to filename" checkbox. 

You should have the following code at this point.

{ INCLUDETEXT { FILENAME \P \* MERGEFORMAT } }

Finally modify the code manually by adding enclosing double quotes and the version.txt file relative to the filename:

{ INCLUDETEXT "{ FILENAME \P \* MERGEFORMAT }\\..\\version.txt" }
