如何让Delphi调用外部程序并等待其运行结束
展开全部
调用下面的WinExecAndWait32 函数即可。
function WinExecAndWait32(FileName:String; Visibility : integer): DWORD;
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 { pointer to PROCESS_INF }
)
then Result := $FFFFFFFF else begin
WaitforSingleObject(ProcessInfo.hProcess,INFINITE);
GetExitCodeProcess(ProcessInfo.hProcess,Result);
end;
end;
procedure TForm1.N9Click(Sender: TObject);
var i:integer;
begin
WinExecAndWait32('PAS2 >tempc2.txt',0);
EXECUTEFILE('notepad.EXE','tempc2.txt','',sw_showmaximized);
end;
