The disappointment came when I tried other video formats than my standard test video (AVI DivX MP3), e.g. I managed to grab frames at specified positions after editing the COM interface - I do not exactly remember where but I had to replace a byte parameter with a IntPtr one. I tried to use ActiveX and its COM interface in C#.

Luckily that skill let me reach my goal for the video library - and it is highly improvised. Coming with working on the Compact Framework and different mobile devices comes a resignation, that if you want to do something the Windows OS on a device does not offer natively, you end up improvising a lot.

I am using C# at work - mainly C# 3.5 CF - and to my shame I do not have much experience with other programming languages. This article will be about taking snapshots from almost any video file. Information also means video snapshots so you can instantly see what video file it is. I am creating a library for my video files and want it to be capable of extracting as many information from a file as possible so the user (mainly me) can be as lazy adding new videos as possible.
