要判断其他程序是否终止, 可以使用FinWindow. 如果您需要调用一个外部程序,
直到外部程序执行完才返回, 可以用下面的方法:
function WinExecAndWait32(FileName:String;
Visibility :
integer):integer;
var
zAppName:array[0..512] of char;
zCurDir:array[0..255] of char;
WorkDir:String;
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);
end;
end;
