Hello every one,

I am doing a research program and my professor asked to do this in VBA (I never used it). Let me explain:

I need to create arrowhead among certain points. Every two points are arcs for a map, and some of them are 'bothway' (I can go from point A to B and vice versa, so I would use an arrow with two heads) and others are 'oneway'.

For example: Arc 1 (Oneway): Start point: 5 (5,10, this is the coordinate); End point:6 (20,10); I would need an arrow with one head starting from point 5 to point 6.
Arc 2 (bothway): Start point: 8 (7,22); End point:6 (20,10); I would need an arrow with two heads starting from point 8 to point 6.

Then, I have to do this for all my arcs and I already know which of them are 'oneway' or 'bothway'.

I hope it is clear, I do not know where to start because only yesterday was my first day working on vba (I was working on Matlab).

Thanks everyone,

Caio Souza.
