EnumDesktops
The EnumDesktops function enumerates all desktops in the window station assigned to the
calling process. The function does so by passing the name of each desktop, in turn,
to an application-defined callback function.
BOOL EnumDesktops(
HWINSTA hwinsta,
| // handle to window station to enumerate
| DESKTOPENUMPROC lpEnumFunc,
| // points to application's callback function
| LPARAM lParam
| // 32-bit value to pass to the callback function
| );
|
|
Parameters
hwinsta
Specifies the handle to the window station whose desktops are to be
enumerated. The CreateWindowStation, GetProcessWindowStation, and OpenWindowStation functions return a window station handle.
lpEnumFunc
Points to an application-defined EnumDesktopProc callback function.
dwDesiredAccess
Specifies a 32-bit application-defined value to be passed to the callback
function.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
Remarks
The calling process must have WINSTA_ENUMDESKTOPS access to the window
station. The EnumDesktops function enumerates only those desktops for which the calling process has
DESKTOP_ENUMERATE access.
The EnumDesktops function repeatedly invokes the lpEnumFunc callback function until the last desktop is enumerated or the callback
function returns FALSE.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
