| 释义 | OpenInputDesktop 语法： C++ HDESK WINAPI OpenInputDesktop( __in DWORD dwFlags, __in BOOL fInherit, __in ACCESS_MASK dwDesiredAccess ); OpenInputDesktop功能 打开桌面接收用户输入。 参数 dwFlags [in] 此参数可以是零或以下的价值。 ValueMeaning DF_ALLOWOTHERACCOUNTHOOK 0x0001Allows进程中的其他帐户运行在桌面上设置钩子在这一进程中。 fInherit [in] 如果该值为TRUE，进程创建的这一进程将继承处理。否则，该进程不会继承此处理。 dwDesiredAccess [in] 到桌面访问。如需使用权名单见桌面安全和访问权限。 返回值 如果函数成功，返回值是一个句柄到桌面接收用户输入。当您使用完的处理，调用CloseDesktop函数将其关闭。 如果函数失败，返回值为NULL。为了获得更多错误信息，调用GetLastError。 备注 调用进程必须有一个相应的窗口站，无论是在分配过程中创建时系统或SetProcessWindowStation集。窗口站与调用进程关联必须能够接收输入。 一个应用程序可以使用SwitchDesktop函数来更改输入桌面。 如果dwDesiredAccess参数指定次数READ_CONTROL，WRITE_DAC，或WRITE_OWNER标准访问权限，您还必须要求DESKTOP_READOBJECTS和DESKTOP_WRITEOBJECTS访问权限。 要求： 最低支持：client－Windows 2000专业版 最低支持server－Windows 2000服务器 HeaderWinuser.h(头文件：winuser.h) LibraryUser32.lib DLLUser32.dll 参见 CloseDesktop 台式机 SetProcessWindowStation SwitchDesktop 窗口站和桌面功能 如果有任何问题和意见，请发送给微软(wsddocfb@microsoft.com) 生成日期：2009年8月27日 ＝＝英文原文＝＝OpenInputDesktop Function Opens the desktop that receives user input. Syntax C++ HDESK WINAPI OpenInputDesktop( __in DWORD dwFlags, __in BOOL fInherit, __in ACCESS_MASK dwDesiredAccess ); Parameters dwFlags [in] This parameter can be zero or the following value. ValueMeaning DF_ALLOWOTHERACCOUNTHOOK 0x0001Allows processes running in other accounts on the desktop to set hooks in this process. fInherit [in] If this value is TRUE, processes created by this process will inherit the handle. Otherwise, the processes do not inherit this handle. dwDesiredAccess [in] The access to the desktop. For a list of access rights, see Desktop Security and Access Rights . Return Value If the function succeeds, the return value is a handle to the desktop that receives user input. When you are finished using the handle, call the CloseDesktop function to close it. If the function fails, the return value is NULL. To get extended error information, call GetLastError . Remarks The calling process must have an associated window station, either assigned by the system at process creation time or set by SetProcessWindowStation . The window station associated with the calling process must be capable of receiving input. An application can use the SwitchDesktop function to change the input desktop. If the dwDesiredAccess parameter specifies the READ_CONTROL, WRITE_DAC, or WRITE_OWNER standard access rights, you must also request the DESKTOP_READOBJECTS and DESKTOP_WRITEOBJECTS access rights.
