| 释义 | DdeKeepStringHandle 语法： BOOL DdeKeepStringHandle( DWORD idInst, HSZ hsz ); DdeKeepStringHandle功能 该DdeKeepStringHandle函数的使用计数与指定的处理相关的增量。此功能使应用程序保存字符串句柄传递给应用程序的动态数据交换(DDE)回调函数。否则，一字符串句柄传递给回调函数被删除时，回调函数返回。此函数也可以用来保存字符串处理由CONVINFO结构引用一份则由DdeQueryConvInfo函数返回。 参数 idInst [in]指定的应用程序实例标识符先前调用DdeInitialize函数获得。 hsz [在，出]句柄字符串句柄被保存。 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。 功能信息 最低DLL版本 user32.dll 在Ddeml.h HeaderDeclared，头文件：winuser.h import libraryUser32.lib 最低操作系统Windows 95，Windows NT 3.1 参见 动态数据交换管理库概况，CONVINFO，DdeCreateStringHandle，DdeFreeStringHandle，DdeInitialize，DdeQueryConvInfo，DdeQueryString ＝＝英文原文＝＝DdeKeepStringHandle Function The DdeKeepStringHandle function increments the usage count associated with the specified handle. This function enables an application to save a string handle passed to the application's Dynamic Data Exchange (DDE) callback function. Otherwise, a string handle passed to the callback function is deleted when the callback function returns. This function should also be used to keep a copy of a string handle referenced by the CONVINFO structure returned by the DdeQueryConvInfo function. Syntax BOOL DdeKeepStringHandle( DWORD idInst, HSZ hsz ); Parameters idInst [in] Specifies the application instance identifier obtained by a previous call to the DdeInitialize function. hsz [in, out] Handle to the string handle to be saved. Return Value If the function succeeds, the return value is nonzero. If the function fails, the return value is zero.
