Pushpins in current view

Hello,

Is there an easy way to get all the pushpins in the current map view? (Mappoint 2004)

Now I have the following solution:

MapPoint.Location[] locations = new MapPoint.Location[5];
locations[0] = myMap.XYToLocation(myMap.Left, myMap.Top);
locations[2] = myMap.XYToLocation(myMap.Left, myMap.Height);
locations[4] = myMap.XYToLocation(myMap.Width, myMap.Height);
locations[6] = myMap.XYToLocation(myMap.Width, myMap.Top);
locations[8] = myMap.XYToLocation(myMap.Left, myMap.Top);

and then a do a QueryPolygon on my dataset.

Is there another (better/easier) way to do this?

Thanks

Not sure if you are are working in vb6 or what lang.

Or with Dataset

but perhaps the following will help bring further insight:

The useful bit I found in a similar pursuit was the QueryAllRecords

I've got some other non-relevant info here (some might say more than less !) just ignore that though.

'For each pushpin, output the lat/lon and symbol lines.
For Each objDataSet In m_objMap.DataSets
Set objRecordset = objDataSet.QueryAllRecords
objRecordset.MoveFirst
Do Until objRecordset.EOF
CalcPos m_objMap, objRecordset.Pushpin.Location, dblLat, dblLon
m_colMIFLines.Add "Point " & CStr(Round(dblLon, 6)) & " " & CStr(Round(dblLat, 6)) & vbCrLf
m_colMIFLines.Add " Symbol (44,13395711,10)" & vbCrLf
strnote = ""
'Add information in the balloon and note fields to the data to be written.
For Each objField In objRecordset.Fields
If objField.VisibleInBalloon Then
strnote = strnote & objField.Name & ": " & CStr(objField.Value) & "> "
End If
Next
If Len(strnote) >= 2 Then
strnote = left$(strnote, (Len(strnote) - 2))
End If
If objRecordset.Pushpin.Note <> "" Then
strnote = strnote & IIf(strnote <> "", "> Note: ", "") & objRecordset.Pushpin.Note
End If

'Add a data line to the mid file, including the pushpin data and symbol.
m_colMIDLines.Add Chr$(34) & objRecordset.Pushpin.Name & Chr$(34) & "," & CStr(m_lObjectCount) & "," & objRecordset.Pushpin.Symbol & ",0," & Chr$(34) & left$(strnote, 255) & Chr$(34) & vbCrLf

'Update the object count.
' frmSpatialDataImport.lblRecordCount.Caption = "Shape Count: " & m_lObjectCount
DoEvents
m_lObjectCount = m_lObjectCount + 1
objRecordset.MoveNext
Loop
Next

Thanks for your reply.
I am working in C# .Net.
To explain further, my goal is to get only the PushPins visible in the current view.
I have a MapPoint dataset containing al the puspins that are placed on the map. Now I want a subset of this dataset containing only that pushpins that are visible in the current view of the map.

Hi,

Then calculate lat/long of the 4 corners of the map in view and you can easy calculate wht is in view or not
