  Hi,

  I'm investigating moving (part of) the functionality of a VB6 Windows application into the web-world.  In principle the requirement is rather simple:

  Based on a set of data retrieved from a database, a schematic is drawn.  The solution for that, as far as I have figured it out by now, is to create a bitmap in memory, use the system.drawing features to create the schematic, and then output it onto the page.

  First question: is this indeed the best way to do it, or do you suggest to use a control (like the picture-control in VB6) ?

  This is the basic functionality, but to make this really useful for the users, it should be possible for them see additional information, or to start actions based on where they are with the mouse, or click on the schematic.  In the VB6 app this is done through the MouseOver and other events.

  Second question: what is the best way to replicate this functionality ?

  Thanks in advance for your help.

  Regards,

  Erwin
