Hi,

I have an explorer object of link, and I would like user to be able to drag and drop an arrow and only after set the Start/End connection.

Dim MyArrow As New Arrow(MyFlowChart)
MyFlowChart.Add(MyArrow)

When I try this code, nothing append on my flowchart

Hi,

Again you might have to use "new DummyNode()" as arrow's origin and destination, or otherwise the control won't display the arrow. Or call the FlowChart.CreateArrow(PointF, PointF) method which will create the nodes for you.

I try create my arrow with DummyNode like that :

Dim MyArrow as new Arrow(MyArrowPrototype, New DummyNode(MyFlowChart),New DummyNode(MyFlowChart))

Have you tried setting the Arrow.ControlPoints coordinates to ones in the visible area? The default might be (0,0) for all points, and you won't see the arrow then.
