I am trying to use netmeeting api to do a application sharing program.

I want to know if netmeeting SDK provides API to unshall all shared application by one click, so that I can close the application sharing window.

Besides, does it also provide api to let me share (i.e picture) in true colour?

I cannot find resources about these 2 issues, but I can see that netmeeting have this 2 buttons.

Can anyone show me how to implement?
