MapForums

I've written a small utility that uses MapPoint to import pushpins into a map containing various shapes. I then can report which pushpins are within a shape and which are not.

The problem I am having is that my MapPoint control already has "My Pushpins" which causes me to write two reports. One is for the data that I've imported and one is for the "My Pushpins" dataset.

How do I go about deleting the default set?

If I add the ability to manually enter a location as a pushpin, how do I define which dataset it should go into?

I'm a relatively new programmer using C#, so I appreciate any help with these bone-head questions.

Thanks!

MapPoint always adds new pushpins to the default dataset.
If you delete the default "MyPushpins" it will be recreated when the next pushpin is added.
If you rename "MyPushpins" MapPoint will then create "MyPushpins1" as the default dataset when the next pushpin is added.

The only way seems to be to create a new dataset and move the newly added pushpin to this as below.

Public Sub AddPushpin( _
____ByVal DataSetName As String, _
____ByVal objLoc As MapPoint.Location)

Dim objPin As MapPoint.Pushpin
Dim DataSetFound As Boolean
Dim intX As Integer

'loop through dataset collection
For intX = 1 To objMap.DataSets.Count
____'if dataset name exists
____If objMap.DataSets.Item(intX).Name = DataSetName Then
________'do not add dataset name
________DataSetFound = True
________Exit For
____End If
Next intX

'if dataset name does not already exist
If Not DataSetFound Then
____'add dataset name to dataset collection
____objMap.DataSets.AddPushpinSet DataSetName
End If

'add pushpin to default dataset
Set objPin = objMap.AddPushpin(objLoc)

'move pushpin from default dataset to required dataset
objPin.MoveTo objMap.DataSets.Item(DataSetName)

End Sub

Sorry this is in VB but the general idea is the same.

Thanks! Maybe I'll use a C# version of this just before running my report to combine all pushpins into one dataset. This way I only get one report instead of one for each dataset.
