IX3

Hey All,
 
I purchased a little known program called InstantEXE (IX3) which, from what I understand, was created in VB.  I am assuming, and it is apparent in many respects, that this program understands VB language in some respects.
 
I am trying to write an application in this program that has tree capabilities but there is not enough information out there about this program to learn from.  As far as I have experimented, the application does not recognize parents, children, nodes, branches, or connectors.  I am probably using them incorrectly at that.
 
So, I am left to use "draw" commands.  IX3 contains a control panel that allows me to draw elipses, boxes, lines, and etc...When I go into the command box I am asked only to define the characteristics of the line I am drawing.  There is also an input section to enter the X and Y positions, height, and length. 

Does anyone know what I can enter in these boxes to tell the application to auto draw a line between Box A and Box B?
 
Thanks,
