I wan\'t to customize the icon displayed within the windows 7 taskbar. When my app is running, I can do it by changing main window icon but, when the app is pinned, the exe\
I don't know if I'm understanding your problem but..
If you create an application and put the icon property of the main window, that icon will appear in the taskbar also. But, if you pin-it to the taskbar, that icon dissapear. Am I right? If so, go to the project properties and in the application tab, put the icon that you want for the exe. Now, you will see that icon in the taskbar when pinned.
I Use the same icon for both things :P
