I'm fairly new to the MP 2004 Active-X control for VS.NET 2003, so forgive me if this is a basic question.

I'm populating pushpins on a territory map to represent a technician's stops for the day. My default altitude is 30 miles, and sometimes a pushpin falls outside the map if the stop is out of the way.

Is there any way to determine if a new pushpin is going to fall outside the viewable map area, so I can increase the map object's altitude?

Thanks in advance,

This sample is in VB6 but I'm sure you will be able to get the idea. I'm just counting the number of pushpins visible but you could use this to test the pushpin names compared to the name of the pushpin your worried about.

Code:

'Query number of pushpins visible on screen 

Dim objmap As MapPointctl.Map 
Set objmap = MappointControl1.ActiveMap 
Dim objDataSet As MapPointctl.DataSet 
Dim objRecords As MapPointctl.Recordset 

Dim objLocs(1 To 5) As MapPointctl.Location 
Set objLocs(1) = objmap.XYToLocation(objmap.Left, objmap.Top) 
Set objLocs(2) = objmap.XYToLocation(objmap.Width, objmap.Top) 
Set objLocs(3) = objmap.XYToLocation(objmap.Width, objmap.Height) 
Set objLocs(4) = objmap.XYToLocation(objmap.Left, objmap.Height) 
Set objLocs(5) = objmap.XYToLocation(objmap.Left, objmap.Top) 

lngCount = 0 

For Each objDataSet In objmap.DataSets 
Set objRecords = objDataSet.QueryPolygon(objLocs) 
objRecords.MoveFirst 
Do While Not objRecords.EOF 
lngCount = lngCount + 1 
objRecords.MoveNext 
Loop 
Next 
MsgBox "Number of records in polygon: " & lngCount
