I took a break from arguing with our GIF decoder to take a quick look at the BBM format as I have a few files in that format containing colour palettes I wished to extract. When I looked into this, I found a BBM file is essentially an LBM file without any image data, so I set to work at writing a new palette serializer for reading and writing the palette files. This article describes how to read the palettes from BBM and LBM files.

Sometimes you may wish to create an application that sits running in the background but doesn't actually display an initial user interface. However, the user can interact with the application and so therefore its not appropriate to be a service. Often such applications are accessible from a system tray icon. Another viable requirement might be for multiple top level windows, for example recent versions of Microsoft Word, where each document has its own application window.
By default however, a normal Windows Form application displays the start-up form which definitely isn't desirable, especially as hiding this form isn't as straightforward as you might expect. Fortunately however, the framework provides us with the
ApplicationContext class that can be used by
