我有蝙蝠文件,這使得一些操作。如何從Delphi運行此文件並等待,直到停止。 類似的東西:德爾福:等到蝙蝠腳本運行到底
procedure TForm1.Button1Click(Sender: TObject);
begin
//Starting bat-file
bla-bla-bla
showmessage('Done');
end;

這執行給定的命令行,並等待通過命令行啓動退出程序。如果程序返回零退出代碼,則返回true;如果程序未啓動或返回非零錯誤代碼,則返回false。
function ExecAndWait(const CommandLine: string) : Boolean;
var
StartupInfo: Windows.TStartupInfo; // start-up info passed to process
ProcessInfo: Windows.TProcessInformation; // info about the process
ProcessExitCode: Windows.DWord; // process's exit code
begin
// Set default error result
Result := False;
// Initialise startup info structure to 0, and record length
FillChar(StartupInfo, SizeOf(StartupInfo), 0);
StartupInfo.cb := SizeOf(StartupInfo);
// Execute application commandline
if Windows.CreateProcess(nil, PChar(CommandLine),
nil, nil, False, 0, nil, nil,
StartupInfo, ProcessInfo) then
begin
try
// Now wait for application to complete
if Windows.WaitForSingleObject(ProcessInfo.hProcess, INFINITE)
= WAIT_OBJECT_0 then
// It's completed - get its exit code
if Windows.GetExitCodeProcess(ProcessInfo.hProcess,
ProcessExitCode) then
// Check exit code is zero => successful completion
if ProcessExitCode = 0 then
Result := True;
finally
// Tidy up
Windows.CloseHandle(ProcessInfo.hProcess);
Windows.CloseHandle(ProcessInfo.hThread);
end;
end;
end;

下面是一些代碼,例如 - 在Windows 7工作正常,是無形的
(funcion ExeAndWait是借的)。
function ExeAndWait(ExeNameAndParams: string; ncmdShow: Integer = SW_SHOWNORMAL): Integer;
var
StartupInfo: TStartupInfo;
ProcessInformation: TProcessInformation;
Res: Bool;
lpExitCode: DWORD;
begin
with StartupInfo do //you can play with this structure
begin
cb := SizeOf(TStartupInfo);
lpReserved := nil;
lpDesktop := nil;
lpTitle := nil;
dwFlags := STARTF_USESHOWWINDOW;
wShowWindow := ncmdShow;
cbReserved2 := 0;
lpReserved2 := nil;
end;
Res := CreateProcess(nil, PChar(ExeNameAndParams), nil, nil, True,
CREATE_DEFAULT_ERROR_MODE
or NORMAL_PRIORITY_CLASS, nil, nil, StartupInfo, ProcessInformation);
while True do
begin
GetExitCodeProcess(ProcessInformation.hProcess, lpExitCode);
if lpExitCode <> STILL_ACTIVE then
Break;
Application.ProcessMessages;
end;
Result := Integer(lpExitCode);
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
ExeAndWait(ExtractFilePath(Application.ExeName) + 'test.bat', SW_HIDE);
ShowMessage('Done!');
end;
PS。如果你喜歡,你可以在運行時使用TStringList類構建批處理文件。
缺少關鍵點(批處理命令文件需要通過''C'開關將它們作爲參數傳遞給'cmd.exe'來執行)。 – mghie 2010-03-14 21:53:14
