Summary: Demonstrates how to set Rhino's command prompt text to show the progress of long processes.

How can I show the progress, for a process will execute for a long time, on the command line?

For example, this is what Rhino's IGES importer prints:

See the following sample code.

CRhinoCommand::result CCommandTest::RunCommand( const CRhinoCommandContext& context )
{
  ON_wString prompt;
  int i, entity_count = 1000;
  for( i = 0; i < entity_count; i++ )
  {
    prompt.Format( L"Importing IGES entity %d of %d", i+1, entity_count );
    RhinoApp().SetCommandPrompt( prompt );
    RhinoApp().Wait(0);
 
    // TODO:
  }
  RhinoApp().Print( L"IGES import successful.\n" );
 
  return success;
}
