Determining if MSN Is in the Sign-in StateThe following code example shows the usage of a mutex object to determine if MSN Explorer is signed in.Note This mutex object is available for use in checking MSN Explorer 7.x sign-in status. It may be unavailable in subsequent versions.HANDLE hMSNSignedInMutex; http://msdn.microsoft.com/library/default.asp?url=/library/en-us/devnotes/winprog/determining_if_msn_is_in_the_signin_state.asp 如下: hMSNSignedInMutex = OpenMutex(SYNCHRONIZE, FALSE, "{ECCC50B5-064B-4693-B104-925714A4C74B}");if (hMSNSignedInMutex != NULL) { // MSN Explorer is signed in } CloseHandle(hMSNSignedInMutex);不知道除了根据这个写扩展模块以外还有没有其他的方法,@_@
