Delete previous pushpins

Hi,
I cant able to resolve the problem of deleting previous pushpin and get mine visible pushpin only. I tried for deleting PP dataset and then add new one but not able to get control on program. ....please let me help to come out of this problem. Any one who knows C#.... object o = "Pushpins";
Pushpin a =null;
a= axMappointControl1.ActiveMap.AddPushpin(loc, "hi");
try
{

//MapPoint.DataSet Pushpins = axMappointControl1.ActiveMap.DataSets.get_Item(ref o);
MapPoint.Recordset rs = axMappointControl1.ActiveMap.DataSets.get_Item(ref o).QueryAllRecords();
MapPoint.DataSet pushpin = axMappointControl1.ActiveMap.DataSets.AddPushpinSe t("new");
a.Delete();
rs.MoveFirst();
while (!rs.EOF)
{
axMappointControl1.ActiveMap.DataSets.ZoomTo();
rs.Pushpin.MoveTo(pushpin);
rs.MoveNext();
}

}
catch { }
}

Hi,

This delete all your pushpins:


object o = "My Pushpins";
try {
MapPoint.DataSet ds = MP.ActiveMap.DataSets.get_Item(ref o);
ds.Delete();
catch {
// Dataset does not exists
}

Thanks. Mine code is deleting previous Pushpin but I want mainting mine current pushpin visible. Lets say if I insert the lat & lon it will show on Map. Next when I put again Lat & Lon I want mine previous Pushpin to be delete and keep mine current pushpin visible. I tried with your mentioned code but it delete pushpin with in second.
MapPoint.Map MP = axMappointControl1.ActiveMap;
Pushpin pp = null;
pp = MP.AddPushpin(loc,"hi");
object o = "My Pushpins";
try
{
MapPoint.DataSet ds = axMappointControl1.ActiveMap.DataSets.get_Item(ref o);
ds.Delete();
}
catch{}
}
