Why is aiSee a single executable and not an object-oriented library for C++, for example?

A C library version of aiSee is available on request to selected customers.

Using GDL (Graph Description Language), a purely textual exchange, offers a number of advantages:

• GDL specifications can be produced from all programming languages
  (including Perl, Java, Ruby, PHP, ASP/.NET, Visual Basic, C, and C++).
• Debugging is less complicated (many people find this invaluable).
• DLL problems are avoided.

If you prefer the OO style, we recommend writing a small library that produces GDL from your internal graph class. This is usually quite straightforward, and the additional overhead is small as compared to the complexity of the layout task.

Can aiSee communicate back to my application if I integrate aiSee into it?

aiSee features the concept of User Actions enabling commands to be associated with nodes. For example, this means that nodes can be selected and their titles communicated to an application for processing.

How do I get information on the DDE interface?

There is a small C-program on this website that demonstrates the use of aiSee's DDE interface. The sources are contained in a self-extracting zip file.

Note: if you don't want aiSee to talk back to your application, you won't need the DDE interface in the first place. All of aiSee's functionality can be easily accessed via the command line and/or the GDL file itself. The DDE interface is only useful for communicating certain user actions back to your application.

How do I tell aiSee to reload its current graph from Visual Basic?

Dim aiSeeConnection As Long
aiSeeConnection = DDEInitiate(app:="VCG Server", topic:="VCG Anim")
' Send one byte, ASCII code 1 = reload
DDEExecute aiSeeConnection, Chr(1)
DDETerminate aiSeeConnection
