Answer 1

shellexecute(handle,close,pchar(Path/filename),nil,nil,sw_shownormal);

Answer 2

当然用win32 api,有这个函数.

Answer 3

怎样监视调用的程序是否已经结束看看这个例子：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;
