I'm using GxDialog to save a feature class, which can be a shp or a pgdb / fgdb feature class. I want to know whether to overwrite existing fc. I'm using pGxDialog.ReplacingObject property. It works fine for shapefiles (i.e. msgbox shows up and the pGxDialog.ReplacingObject property is set accordingly), but when I change GxFilter to Geodatabase it doesn't work.
