怎样监控程序中调用的外部程序是否已经运行结束？

[綏子]

你怎么把我要问的问题问了

[tg123]

WaitForSingleObject

[pianopan]

我回去看看，
有没有更详细的解释？

看看这个例子：

function WinExecAndWait32(FileName:String; Visibility : integer):integer;
var
zAppName:array[0..512] of char;
zCurDir:array[0..255] of char;
WorkDir:String;
tempResult :DWORD;
StartupInfo:TStartupInfo;
ProcessInfo:TProcessInformation;
begin
StrPCopy(zAppName,FileName);
GetDir(0,WorkDir);
StrPCopy(zCurDir,WorkDir);
FillChar(StartupInfo,Sizeof(StartupInfo),#0);
StartupInfo.cb := Sizeof(StartupInfo);
StartupInfo.dwFlags := STARTF_USESHOWWINDOW;
StartupInfo.wShowWindow := Visibility;
if not CreateProcess(nil,
zAppName, { pointer to command line string }
nil, { pointer to process security attributes }
nil, { pointer to thread security attributes }
false, { handle inheritance flag }
CREATE_NEW_CONSOLE or { creation flags }
NORMAL_PRIORITY_CLASS,
nil, { pointer to new environment block }
nil, { pointer to current directory name }
StartupInfo, { pointer to STARTUPINFO }
ProcessInfo) then Result := -1 { pointer to PROCESS_INF }
else begin
WaitforSingleObject(ProcessInfo.hProcess,INFINITE);
GetExitCodeProcess(ProcessInfo.hProcess,Result);
Result := tempResult;
end;
end;

[torble]

通过 GetExitCodeProcess 返回 (Result) 进程结束
