I have an ArcGIS custom IGPFunction tool. I want to use the GP progress dialog not the progress bar at the bottom of the ArcGIS 10 window as I don't want people to interact with the map whilst it's processing.
In the Execute method you have an instance of ITrackCancel but I can't work out how to show the default GP progress dialog from there. I have this as code at the moment but it still doesn't show the dialog. Any ideas?
IStepProgressor pStepPro = (IStepProgressor)TrackCancel;
pStepPro.MinRange = 0;
pStepPro.StepValue = 1;
pStepPro.Message = "Starting Import...";
pStepPro.Position = 0;
pStepPro.Show();
...
pStepPro.Hide();
