I was considering doing this by creating the asp.net code in a web app and calling this either from an asp.net web page or from within wordpress via javascript code. That should be possible shouldnt it? Basically I want to send a group of parameter values and get the app to return either an image of a path generated from those parameters, or gcode to cut the path.
As an aside, is everything running on windows including wordpress? I ask because it would save me some programming time and effort if my web app could execute a program called gcmc ( see http://www.vagrearg.org/content/gcmc) which natively runs on linux, but there is a cross compiled windows version. The last example on that site called wheels is my code and it is patterns / gcode derived from this that I want to display in the asp.net site and also in my blog. Would your system allow me to do that?
I use vsexpress for web and would like to start as soon as I have tidied up the blog a bit more. By the way I read that web apps in 4.5 require full trust hosting so I would like to request that in advance.
