How to create a simple MSI installer using WiX

Posted on August 25th, 2008 in programming | 12 Comments »

Lately I was told at work to create an installer for our new product. Till that moment I used to create exe installers with Inno Setup which has many advantages: it’s easy-to-use, powerfull and (the most important 🙂 ) I used it so many times that creating a new installer is a matter of minutes. But this time I heard a big ‘no-no’ for an exe – it had to be msi.
I created a simple “Setup Project” in Visual Studio, played with it for a while and hoped that will work as expected. Well, it worked, but I was told it needed some customizations (graphics, custom dialogs, launching the installed application after install). After doing some googling I was able to do all those things by editing the setup project and modifying the output MSI with Orca. But because every time I needed to create that installer for the new version I had to do some things (for example in Orca) manually – I really hated this solution. So I used google again and I found a really cool, freeware toolset called WiX which does everything I needed. You just create a XML-like file describing the installer and the toolset creates the MSI for you. Great!

Reading Metastock files

Posted on August 6th, 2008 in programming, Python, Stock exchange | 16 Comments »

Note: a free tool converting Metastock data to text files is available.

The source code is available on GitHub: git://github.com/themech/ms2txt.git.

Last week I decided to check how my trading system performs while playing on different foreign indexes. First I had to download the test data. I found a web page offering the quotations I was interested in – luckily it wasn’t expensive.The problem was (of course it occurred after I had paid) that the data was available only in Metastock format. Of course I use my own software (just as every other programmer 😉 ) that helps me to play stocks and futures and I don’t have Metastock. So I decided I would give it a try and I wrote a tiny program that reads Metastock files and generates text files with quotes. I used my beloved Python. You can find the source here.
