释义 | RestoreDC 语法: BOOL RestoreDC( __in HDC hdc, __in int nSavedDC ); RestoreDC功能 该RestoreDC功能恢复设备上下文(DC)到指定的状态。直流恢复,突然出现过一个堆栈,刚才调用SaveDC函数创建状态信息。 参数 hdc [in] 句柄到DC。 nSavedDC [in] 保存的状态得到恢复。如果此参数是积极的,nSavedDC代表国家的特定实例恢复。如果此参数为负,nSavedDC代表一个实例相对于当前的状态。例如,-1恢复最近保存的状态。 返回值 如果函数成功,返回值为非零。 如果函数失败,返回值是零。 备注 该堆栈可以包含的多个实例的DC的状态信息。如果指定的参数指定的状态不是在堆栈的顶部,RestoreDC删除所有与堆栈和指定的实例顶端状态信息。 要求: 最低支持:client-Windows 2000专业版 最低支持server-Windows 2000服务器 HeaderWingdi.h(头文件:winuser.h) LibraryGdi32.lib DLLGdi32.dll 参见 设备上下文概述 设备上下文函数 SaveDC 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7月11日 ==英文原文==RestoreDC Function The RestoreDC function restores a device context (DC) to the specified state. The DC is restored by popping state information off a stack created by earlier calls to the SaveDC function. Syntax BOOL RestoreDC( __in HDC hdc, __in int nSavedDC ); Parameters hdc [in] A handle to the DC. nSavedDC [in] The saved state to be restored. If this parameter is positive, nSavedDC represents a specific instance of the state to be restored. If this parameter is negative, nSavedDC represents an instance relative to the current state. For example, -1 restores the most recently saved state. Return Value If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. Remarks The stack can contain the state information for several instances of the DC. If the state specified by the specified parameter is not at the top of the stack, RestoreDC deletes all state information between the top of the stack and the specified instance.
