I'm writing an Add-In for ArcGIS 10 and would like to use the standard mouse cursors ArcMap uses (e.g. the info cursor and the edit cursor). I hope it is possible to just use the right reference in the add-in config file and not copy the cursor image file.
You can reference whatever cursor you would like in the config file but you might have to copy the image to your project which is what you don't want to do.
Beyond that you can use the IMouseCursor.SetCursor Method and choose one of the 11 default cursors.
