Hi,

Code:

            MapPoint.DataSets ds = MP.ActiveMap.DataSets;
            object o = "My Pushpins";
            Recordset rs = MP.ActiveMap.DataSets.get_Item(ref o).QueryAllRecords();
            rs.MoveFirst();
            while (!rs.EOF) {
                rs.Pushpin.Delete();
                rs.MoveNext();
            }

This is another approach:

Code:

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

Not works.. sorry...

The member on the request collection doesent exist.. use a valid name or an index

for each of your example i receive same error.

regards.

Hi,

Strange, I tryed both and both are working. Try following:

Code:

object o = 1;

Instead fo the "My Pushpins". I test it and it works also. The first database is the one with the pushpins. Unless of course you have explicitely stored somewhere else (by moving them to another).

I tested it with C# and Mappoint 2004 but should work with other versions also.

You can try this:

Dim i as int
Do While oMap.DataSets.Count > 0
i = oMap.DataSets.Count
oMap.DataSets(i).Delete
Loop
