The Kindle Direct Publishing program is a great way for authors to self-publish their books for Kindle users. There are several limitations however when it comes to readying your book for the Kindle since Kindle only supports very basic HTML. You have to abandon any fancy formatting you may have done in recent word processors and give your book a ’1999 Netscape Navigator 3.0 compatible website’ look.

I recently decided to move one of my Dad’s books into this channel. The book was written in MS-word and formatted to properly print on both sides of a page. Additionally there were many non-standard formatting techniques – eg different Header styles applied to different chapter headings. Properly formatting the book for Kindle would have taken a lot of effort, so I decided to accomplish at least part of that effort, using VBA for MS-word.

The VBA Macro I developed is below with instructions for use. This macro Kindle-readies a word document by:
1 – Transforming Page size to be 4.5″x5.5″, plus very small margins.
2 – Justifies all paragraphs, and reduces their indents to a very small value
3 – Merges all columns within Tables, so there are only tables with one column and as many rows as originally existed. I did this because the tables in my word documents were poorly formatted, and I decided to go with a 1-column table layout that the kindle could handle more easily.
4 – Centers all tables and shapes on the page

This macro will also save the current document and save a copy as a HTML (Filtered) file in a specified subdirectory with a “KDP_” prefix. You can choose to switch off either option.

What this macro does not do -
1 – Clean up headers/footers
2 – Standardize formatting – e.g. the header styles for different sections
3 – Clean up any font issues
4 – Clean up the resulting HTML code  – I recommend running HTMLTidy within Notepad++ on the HTML files generated through this code. One specific problem that HTMLTidy resolved was long strings of space, newline or tab characters that create unnecessary whitespace on the Kindle. As this kind of whitespace may have specific purpose in your word document, I did not make this cleanup part of the code.
5 – Reduce image size. Still need to figure this one out – does Kindle automatically reduce all images to viewable size?
6 – a lot of other issues your word files may have!

Below are instructions on using the code and the code itself. Please note this was made for a very specific purpose, and there are absolutely no warranties of any kind. Use this at your own risk! And take a backup of all your files before proceeding. Also I will only make future updates to the code as required to suit my purpose. This macro was designed and tested on MS Office 2003.

How to use this macro -

1. I run this Macro in the Normal.dot file. See these steps at the end to know how to insert this code into the Normal.dot file
2. After the Macro has been inserted into the Normal.dot file, I created a toolbar button to run it. You could choose to run it from the Tools menu everytime.
3. If you would like to save resulting HTML files in a subdirectory of the folder where your word document is, then modify the KDPPATH variable in the macro.
4. This macro will save the current document (Doc) and also save a HTML version. To stop either option, you can comment out the corresponding line in the macro.
5. Open the word document that you need to convert.
6. Run the macro using the toolbar button or from the Tools menu.
7. Wait until you get a ‘Done’ message box. Then your doc/html file should be ready. The MSWord window will show the HTML file after completion (unless you opted out of the HTML generation).
8. You may need to further work on the DOC file and address other issues before it is finally ready for Kindle formatting. If you do this, you will need to save it as an HTML from the File menu yourself.

How to add a macro to your Normal.dot file

1 – Open MS Word
— Close any documents such as the “New blank document” that opens up.
2 – Click on the menu Tools->Macros->Visual Basic Editor (Alternatively press Alt-F11)
3 – If you don’t see a “Project” pane on the left hand side of the VB editor, click on the menu View->Project Explorer
4 – In the project pane, you should be able to see a high level item called “Normal”, under which there will be a subitem called “Modules”.
5 – If under “Modules”. you see a module called “NewMacros”, then double click on it to open it in the editor. If you don’t, then right click on “Modules”, and select the contextmenu item Insert->Module. Open the new module for editing.
6 – Paste the macro into the module, in the editor window.
7 – Save the file. Close word. Now the macro should be a permanent part of your MSWord and can be used on any word document you open in the future.

Due to security concerns in our vicinity last year, I needed a way to keep tabs on our home while the whole family was away on vacation. The idea was to be able to view images of your home, live over the internet from whereever we were. CCTV solutions weren’t an option as they were expensive and none seemed to have a remote viewing option. I believe now there are advanced Logitech webcams in the market that also pivot and stream images to the net, but again they come at a price, and don’t take care of a few things like problems with your internet connection or laptop power when you’re not available to take care of them.

However, there are freeware/shareware solutions on the internet that allow you to capture your webcam and stream it online, even at a particular schedule.The software that I used was a super little app called Active Webcam from Pysoft.

Further, I needed a software that would take care of laptop restarts/windows crashes/net connection blips (and also auto logging into the net account if the login expires every 24 hrs) and that would automatically start Active Webcam every time the system started up – I decided to code that in VB.

Apart from the software I also needed my personal laptop, regular webcam and a DSL internet connection. I had gprs activated on my phone as well, in order to view the images uploaded.

First, i installed Active Webcam and set it up so it would stream images from the webcam to my website at a specific URL.  (Yes, you need a website host that offers FTP where the images will be uploaded to – possibly there are options to upload to photo services like flickr/photobucket too, or to send emails to you with attached images)

Second, compile the code below into an exe and include that exe in the Windows Startup so it runs at system startup.

When this program runs, it will
- check for internet connection availability, and if not available will to restart the local modem
- if the internet connection doesn’t come up after 3 modem restarts, it will restart Windows. It won’t restart windows more than once in 15 mins though.
- log the laptop’s battery status
- log everything to a remote php file so the logs can be viewed remotely too

Download the entire VB project.

This VB project has :
1. a form called frmMain
2. a module called Module1.bas

The code for both is shown below – a lot of the sections came from various sources on the net, so no claims there and a big thanks to them. Also, it all seemed to work at the time.

Also there are certain urls – while most are simply used to check the internet connection, the ’192.168.1.1′ is my modem’s local admin page that you may need to change accordingly. (In order to restart the modem, I used the code here to login to the local admin at 192.168.1.1 and post my username/password etc to the appropriate file (restartmodem.htm))
