如何在前台用户不觉察的前提下，在后台执行一个控制台的程序？(300分)

我想做一个程序，主窗体中有一个按钮，按下它后，主窗体将执行一个后台的命令行程序，<br>并且等待该命令行程序结束之后，用对话框通知用户。现在的要求是，在整个执行过程中，<br>用户无法觉察到前台的窗体在调用后台程序，而是认为全部任务都是由前台窗体完成的（如<br>不会出现DOS窗口，不会返回后台命令行程序的输出信息等），请问这样的要求应该如何<br>实现。

查看CreateProcess的帮助

那就看你的后台程序有没有窗体和对话框之类的东东了，如果没有，完全可以不出现任何<br>效果的，用createprocess或winexec等都可以运行一个程序。

設成SW_HIDE方式運行就可以了……

to chenxz:<br>&nbsp; 我的后台程序是纯粹的命令行程序，执行过程中没有任何窗体和对话框。CreateProcess<br>的参数很多，请问具体怎么调用，能否给个例子？

没有delphi的了，给个bcb的，具体的看帮助<br><br>&nbsp; &nbsp; &nbsp; &nbsp; AnsiString &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;ProgramName;<br>&nbsp; &nbsp; &nbsp; &nbsp; AnsiString &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;ProgramPath;<br>&nbsp; &nbsp; &nbsp; &nbsp; STARTUPINFO &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; StInfo;<br>&nbsp; &nbsp; &nbsp; &nbsp; PROCESS_INFORMATION &nbsp; &nbsp; ProcInfo;<br>&nbsp; &nbsp; &nbsp; &nbsp; bool &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;CreateCode;<br><br><br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ProgramPath = AppPath;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ProgramName = AppPath + "abcde.exe";<br><br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; StInfo.cb = sizeof(StInfo);<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; StInfo.lpReserved = NULL;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; StInfo.lpDesktop = NULL;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; StInfo.lpTitle = NULL;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; StInfo.dwFlags = 0;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; StInfo.cbReserved2 = NULL;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; StInfo.lpReserved2 = NULL;<br><br><br><br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; try<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; CreateCode = CreateProcess(ProgramName.c_str(),NULL,NULL,NULL,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; false,CREATE_NEW_CONSOLE,NULL,ProgramPath.c_str(),&amp;StInfo,&amp;ProcInfo);<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; catch (...)<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (!CreateCode)<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; MessageBox(Handle,"启动失败","错误",MB_OK + MB_ICONERROR);<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }
