How to hide a window in Windows 7, just like desktop managers do

When I install a virtual desktop manager on Windows 7, and I switch to a different virtual desktop, all the current windows disappear, also disappearing from the Start Menu.

I want to hide some of a particular application's windows, but not all of them, in a similar manner. How can I hide a window like this?

In particular, I need to hide a VirtualBox Seamless mode window, so I'm not sure minimizing 开发者_StackOverflow中文版the window will work. It does, however, disappear when using virtual desktop managers.

The same window cannot appear on multiple desktops. If you need your application window to appear on multiple desktops you need to create a separate window for each desktop. The desktop a window appears on depends on the thread that creates the window. You can change the desktop thread assignment using the SetThreadDesktop function.

The answer is simply ShowWindow(SW_HIDE) and ShowWindow(SW_SHOW). I think "Virtual Desktop Managers" just hide windows and show them as necessary when the desktops change.
