Alternatives to Using Symbol Designer
You can also create CODSymbolComponent objects for your application programmatically. For example, if you already have a number of bitmap resources that you want to use as symbols in your application, you can create a symbol object and then add the bitmap of your choice to the symbol’s definition.
Symbol Designer always creates CODSymbolComponent objects. If you want to derive from CODSymbolComponent to add functionality to the symbol, you need to create the derived symbol object from the symbol object you defined in Symbol Designer. You can also create a derived symbol object dynamically in your application.
