Hi,

This code can come in handy but I was hoping to find that the zip file contained a bit of documentation of some kind, could you perhaps clarify something for me?

How does this work exactly? Is there a reference guide on how to use this coredll and what functions it contains?

[DllImport("coredll")]

private extern static bool NLedGetDeviceInfo(Int32 nID, NLED_SETTINGS_INFO nsi);

[DllImport("coredll")]

private extern static bool NLedSetDevice(Int32 nID, NLED_SETTINGS_INFO nsi);

Kind Regards,

Goedendag Miguel,

If I remember correctly, it is this 'Vibrating your PocketPC device!' article that inspired / helped us putting together this C# code sample

Now with regards to your "how to use this coredll and what functions it contains" question, let me bring the following articles to your attention:

- [.NET Compact Framework] Creating a P/Invoke Library
- [C# Programmer's Reference] Platform Invoke Tutorial
- [Visual Studio Technical Articles] Using P/Invoke to Call Unmanaged APIs from Your Managed Classes
- P/Invoke.net (see the Smart Device Functions section)
- [Platform Builder for Microsoft Windows CE 5.0] coredll Module

I do hope this helps.
Tot ziens!

Jacques
