Error in use of GraphViz command line executables

[ghbhat]

Hi Jamie,

Thanks for this very useful wrapper! It works well when I provide a location like "C:\GraphViz\bin" in the web.config file. However, when I include the GraphViz executables in my application's bin itself, and try to provide a relative path (or no path) in the web.config file, I get the error 'The system cannot find the file specified'. Your documentation indicates that there is some way to do this (call the executables from the app's bin without providing an absolute path to them), but I couldn't figure out how... Please guide me?

I do this when running under Asp.Net MVC:

var getStartProcessQuery = new GetStartProcessQuery();
var getProcessStartInfoQuery = new GetProcessStartInfoQuery();
var registerLayoutPluginCommand = new RegisterLayoutPluginCommand(getProcessStartInfoQuery, getStartProcessQuery);
var wrapper = new GraphGeneration(getStartProcessQuery, getProcessStartInfoQuery, registerLayoutPluginCommand);

wrapper.GraphvizPath = Server.MapPath("~/Some/Path/Graphviz/bin");

byte[] output = wrapper.GenerateGraph("digraph{a -> b; b -> c; c -> a;}", Enums.GraphReturnType.Png);

:)
