MoveUp

Moves the current shape pointer up the shape network, taking the specified path.


VB.NET Usage

Function MoveUp(UpIndex As Integer) As Boolean

            Parameters

UpIndex

The index of the shape in the shape network to use as the upstream path. This is necessary because a node may have more than one upstream path.
ReturnValue A boolean value representing the success or failure of moving the current shape pointer up in the shape network.

Sample Code

    Private Sub ShapeNetworkMoveUp()
        Dim sf As New MapWinGIS.Shapefile()
        Dim shapenetwork As New MapWinGIS.ShapeNetwork()
        Dim result As Integer, shapeindex As Integer
        'Open a line shapefile
        sf.Open("C:\test.shp")
        'Build a shape network from the shapefile using shape 0 as the outlet shape and point 0 in shape 0 as the outlet point
        result = shapenetwork.Build(sf, 0, 0, 10, MapWinGIS.AmbiguityResolution.DISTANCE_TO_OUTLET)
        'Move the shape pointer up in the shape network using shape 1 as the path
        shapenetwork.MoveUp(1)
    End Sub
  

VB 6 Usage
Function MoveUp(UpIndex As Long) As Boolean
            Parameters

UpIndex

The index of the shape in the shape network to use as the upstream path. This is necessary because a node may have more than one upstream path.
ReturnValue A boolean value representing the success or failure of moving the current shape pointer up in the shape network.

Sample Code

    Private Sub ShapeNetworkMoveUp()
        Dim sf As New MapWinGIS.Shapefile
        Dim shapenetwork As New MapWinGIS.shapenetwork
        Dim result As Long, shapeindex As Long
        'Open a line shapefile
        sf.Open ("C:\test.shp")
        'Build a shape network from the shapefile using shape 0 as the outlet shape and point 0 in shape 0 as the outlet point
        result = shapenetwork.Build(sf, 0, 0, 10, MapWinGIS.AmbiguityResolution.DISTANCE_TO_OUTLET)
        'Move the shape pointer up in the shape network using shape 1 as the path
        shapenetwork.MoveUp (1)
    End Sub
