Hello selketime,
maybe I could answer your question
I have a new x50v Axim from Dell and I am also new to Pocket PC's. I would like to run the SiDiary software (my 2 year old has diabetes and is a pumper).
Can anyone help me figure out how and where to put this cabinet file that I downloaded to my person computer from microsoft? I installed the SiDiary on my SD card on the Axim and now I think I have to put this "cab" file somewhere.
If you want to install the dll that is part of this cabinet file to you pocket PC you need to syncronise this file with Microsoft active sync from you Windows PC to your pocked PC.
To do this just activate the Microsoft Active Sync Windo and select Files (in my german Version Dateien) at the bottom of the windows, do a right click and chose options (in my german version Einstellungen). In the upcoming window you need to add the cab file and then Active Sync will copy the cab file to your pocket PC. Please watch if you get an question where the cab file (or the content of the cab file) should be copied.
As I alread installed this I am not sure if any questions will pop up.
Hope this helps to get SiDiary running. If not please come back :-)
Regards
Norbert
