HFlow for .NET Details

HFlow for .NET is a .NET component. It provides the same features as the ActiveX version.

The following VB code is all you need to do to perform a hierarchical layout:
Dim hflow As HFlow = New HFlow()
hflow.LayerDistance = 50 ‘ Sets the distance between adjacent levels.
hflow.VertexDistance = 50 ‘ Sets the distance between adjacent vertices.
hflow.Orientation = North
hflow.LayerWidth = 0 ‘ No limitation in the number of vertices in a level
hflow.Layout(AddFlow1) ‘ Perform the hierarchical layout

This code supposes that you have a form containing an AddFlow for .NET control. In this example, the HFlow component is created dynamically. You create the graph in the AddFlow control, either interactively, either programmatically (in this case, giving each vertex a random position or a (0,0) position). Then you apply the HFlow layout to this graph. And each vertex will be placed at a reasonable position.

Only the logical vertices and edges of the AddFlow control are involved in this layout. This will allow you to apply the layout only to important vertices. For instance, you can exclude a node just used to display a label by setting its Logical property to false.

Notice that it is necessary to use AddFlow for .NET to be able to use HFlow for .NET. Both products are installed via a common installation program.
