Question: I'm currently developing an application that uses private Windows messages to trigger (some) code execution (for programmers: defined as [WM\_USER](https://msdn.microsoft.com/en-us/library/windows/desktop/ms644931%28v=vs.85%29.aspx) + n).

I would like to track the order in which some of these are processed by the OS and handled in my app. I can not find sufficient facilities in my IDE to do so.

A free tool would be nice.

FWIW I Develop in Delphi XE2

[Some PDF to HTML Converter](http://www.somepdf.com/some-pdf-to-html-converter.html) is the only free, offline PDF to HTML converter I was able to find. Hope this works for you!
I know you said standalone - but if you can work with node - this is the best node module I found:

To make things easier - here's a node/webpack project I created to create my CV using HTML
