visual studio extensions - How can I run custom tool or save a file programmatically using EnvDTE? -

i want save/run custom tools on handful of .tt files extension. don't want loop on files in solution/project, rather want able use relative (or full) path of file execute save/run custom tool.

is there way projectitem object given path of file ($(solutiondir)/myproject/myfile.tt) can execute methods on it?

you can use findprojectitem method of envdte.solution type find file within current solution it´s name. executecommand method dependent on current ui context; item must selected, otherwise call fails.

private bool tryexecutetexttemplate(string filename) {     var dte = (dte2)this.getservice(typeof(sdte));     solution solution = dte.solution;     if ((solution != null) && solution.isopen)     {         projectitem item = solution.findprojectitem(filename);         if (item != null)         {             // todo: track item in solution explorer              try             {                 item.dte.executecommand("project.runcustomtool");                 return true;             }             catch (comexception)              {              }         }     }      return false; }
