GetNotificationData的问题？
I am wrapping notification bubble for a specific application and I have Add, Remove working. Now I would like to use GetData but I am running into a wall. I cont to recv result of 87 invalid param, I know I am passing correct clsid (I use same one when I add) and I also know the ID is correct again from add but also from nmshn.hdr.code in winproc. that error seams to me indicates I have the DLLImport statement correct but Im putting it here just the same in case its that.

//GetData

[DllImport( "aygshell.dll ", CallingConvention = CallingConvention.Winapi,

EntryPoint = "#156 ")]

private static extern int SHNotificationGetData(ref Guid clsid, uint dwID, ref SHNOTIFICATIONDATA shinfo);


Also here is the snippet where I am trying to retrieve it.



public unsafe SHNOTIFICATIONDATA GetNotificationData(uint dwID)

{

SHNOTIFICATIONDATA shinfo = new SHNOTIFICATIONDATA();

shinfo.cbStruct = (uint)Marshal.SizeOf(shinfo);

Guid g = new Guid(clsid.ToString());

int err = 0;

err = SHNotificationGetData(ref g, dwID, ref shinfo);

if (err != 0)

throw new Exception( "Error getting data! ");

return shinfo;

}



My next goal is to change my duration and us Update. I know I can use other means (keep copies of my structs locally and get data that way) but I want to really use this function. Thanks.
