best way to sync parts of an app

What is the best way to sync foreground parts of an app with event triggered parts?

I have a piece of code that loads the last used config based on the applicationStart event. 

I find that the foreground part of the app has already put up the information with initial values of the config table. 

What is the best way to postpone the foreground until the applicationStart event has occurred?

Also, is there a recommended way to make sure the splash screen (aka Default.png) image is displayed a specific time?

Thanks!
