| 释义 | DdeFreeStringHandle 语法： BOOL DdeFreeStringHandle( DWORD idInst, HSZ hsz ); DdeFreeStringHandle功能 该DdeFreeStringHandle函数释放字符串处理调用应用程序。 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]句柄字符串处理被释放。这种处理，必须是被以前的调用DdeCreateStringHandle函数创建。 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 应用程序可以自由创建的字符串处理它与DdeCreateStringHandle但不能自由的，该系统传递给应用程序的动态数据交换(DDE)回调函数或CONVINFO结构返回的DdeQueryConvInfo功能的。 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，DdeCmpStringHandles，DdeCreateStringHandle，DdeInitialize，DdeKeepStringHandle，DdeQueryConvInfo，DdeQueryString ＝＝英文原文＝＝DdeFreeStringHandle Function The DdeFreeStringHandle function frees a string handle in the calling application. Syntax BOOL DdeFreeStringHandle( 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 freed. This handle must have been created by a previous call to the DdeCreateStringHandle function. Return Value If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. Remarks An application can free string handles it creates with DdeCreateStringHandle but should not free those that the system passed to the application's Dynamic Data Exchange (DDE) callback function or those returned in the CONVINFO structure by the DdeQueryConvInfo function.
