Custom Build Question?

Question

My C# project will take a project file (xml right now) and build it. Similar to this example: System.Type t = System.Type.GetTypeFromProgID("VisualStudio.Solution.7.1"); object obj = System.Activator.CreateInstance(t, true); soln = (EnvDTE.Solution)obj; soln.SolutionBuild.BuildProject(configuration,projectname, true) If build fails, how do I get a listing of compiler errors? Thanks Gibby
