使用system怎么不出现dos窗口？

[shuibing]

我只想在后台调用dos命令，不想出现黑窗口。谢谢！

创建一个线程

system ("command");

[我来看看CB]

为DOS程序创建快捷方式，设置为最小化运行

或者类似

WinExec("dir",SHOW_HIDE) ;

我简单创建了个线程，在线程里用system，还是有个dos窗口出现。能详细讲下嘛。

最好不用线程，用CreateProcess创建一个进程，有一个参数是控制新进程窗口是否显示的，去查一下MSDN吧。

WinExec("ProgrameName",SHOW_HIDE) ;

[Bird1945]

WinExec("dir",SHOW_HIDE) ;

这样。。。。
void __fastcall TForm1::WaitCall(AnsiString COMMANDSTR)
{
//TODO: Add your source code here
STARTUPINFO StartupInfo;
ZeroMemory( &StartupInfo, sizeof(STARTUPINFO));
StartupInfo.cb = sizeof(STARTUPINFO);
StartupInfo.wShowWindow=SW_MINIMIZE
StartupInfo.dwFlags=1;
PROCESS_INFORMATION ProcessInfo;
if(CreateProcess(COMMANDSTR.c_str()/*ExeFileName.c_str()*/,NULL, NULL, NULL, TRUE, NORMAL_PRIORITY_CLASS, NULL, NULL, &StartupInfo, &ProcessInfo))
{
OpenProcess(PROCESS_TERMINATE/*|SYNCHRONIZE*/,false,(DWORD)ProcessInfo.hProcess);
DWORD dwExitStatus = STILL_ACTIVE;
do
{
if( !GetExitCodeProcess(ProcessInfo.hProcess, &dwExitStatus)) break;
Application->ProcessMessages();
} while (dwExitStatus == STILL_ACTIVE);
}
}
else
{
SystemLog("调用进程出错！！！！");
}
}
