Essbase API

On and off for the last few months I've been playing with the Essbase API and trying to initialize it in C#. Apparently I am in need of some assistance, for the life of me I can't figure out how to get this thing started. I refuse to accept the idea that I should use the JAVA API and expose the functionality through web services (this is what Dodeca does). So really this is just a rant and maybe a shout out asking if anyone has some samples. Coming from a development background I have been kinda shocked that there is so little code available for public view with regards to this API.

Anyway here are some things I was trying this morning but I am giving up on for now and gonna go work on my IMAP stuff.

public unsafe struct EssbaseInit
{
    public ulong Version;
    public ushort MaxHandles;
    public string LocalPath;
    public string MessageFile;
    public string HelpFile;
    public ushort ClientError;
    public ushort ErrorStack;
    public ushort usApiType;
    public Int64 vbCallbackFuncAddress;
}
[DllImport("lib\\esbapin.dll")]
public static extern long EsbInit(IntPtr init, ref long instance);
public static unsafe long EssInit(ESB32.EssbaseInit init, ref long instance)
{
    int size = Marshal.SizeOf(typeof(ESB32.EssbaseInit));
    IntPtr handle = Marshal.AllocHGlobal(size);
    Marshal.StructureToPtr(init, handle, true);
    return EsbInit(handle, ref instance);
}
