How do I create a connection programmatically?

Typically, symbols and links are connected together using the interactive LinkTool UI tool or the LinkCmd command class. Sometimes it is useful to create connections programmatically. For example, you might be generating a diagram from data in a database or possibly even writing your own custom link tool. You might even create a connection between two symbols directly without having a link in between.

The following code creates a link and connects it to the center ports of two symbols:

[C#]

public Link LinkSymbols(Symbol sym1, Symbol sym2) {     
Link link = new Link(Link.Shapes.Line);    
sym1.Connect(sym1.CenterPort, link.TailPort);     
sym2.Connect(link.HeadPort, sym2.CenterPort);    
 return link; }

[VB.NET]

Public Function LinkSymbols(ByVal sym1 As Symbol, ByVal sym2 As Symbol) As Link    
 Dim link As Link =  New Link(Link.Shapes.Line)    
 sym1.Connect(sym1.CenterPort, link.TailPort)    
 sym2.Connect(link.HeadPort, sym2.CenterPort)     
Return link End Function
