The IDesignerDebugging interface allows a designer access to the host's development environment at run time. Through this interface, the designer can request notification when the host IDE enters or leaves run mode.
The IDesignerDebugging interface includes the following methods:
| Method | Description |
| AfterRun | Notifies the designer that the host has exited from run mode and returned to design mode. |
| BeforeRun | Notifies the designer that the host is ready to enter run mode. |
| GetStartupInfo | Specifies which program or URL the host should load when its IDE enters run mode. |
