This article mainly shows you "VC how to get the process through the tray icon", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "how VC gets the process through the tray icon" this article.

This example takes getting the location of the program tray icon as an example.

Win7 has an overflow pallet area: the following is the pallet information hidden in the pallet area, which cannot be found using the above method, because in NotifyIconOverflowWindow

Fhwnd = FindWindow ("NotifyIconOverflowWindow", NULL)
