I am investigating the possibility of writing an application to aid the creation of diagrams such as flowcharts or UML diagrams. How feasible is this using Visual Basic or Visual C++? I would like to be able to create a toolbox of objects that the user can then select and place on the screen, resize, connect etc
Is this simply a case of using the GDI graphic primitives and manipulating them on screen? How do applications like PowerPoint work?
Any info or pointers to resources would be gratefully received?
