Creating LC IDE plugin - is it possible to check if plugin was started automatically or from menu?

[Matthias Rebbe]

Hi,
first of all i am totally new to plugin creation. 
I am working on a plugin which shall be started with LC startup and then close again automatically after executing some task w/o user interaction.
But i need also to run this plugin manually from the plugin menu without running the tasks, because in manual mode i want to start the tasks by pressing a button.
So is there a way to check if a plugin was run at startup or if it was started from the menu?

Regards,
Matthias
