如何完成下面的调用?

[yuaner1978]

我在程序中要实现如何的操作.
运行:1.cmd.exe
2.exp system/syeemis@system file=c:\all.dmp full=y

该如何写代码?谢谢.

system("exp system...");

参考下面的例子：
#define EXECDOSCMD "ipconfig /all" //可以换成你的命令
BOOL ExecDosCmd()
{
SECURITY_ATTRIBUTES sa;
HANDLE hRead,hWrite;

sa.nLength = sizeof(SECURITY_ATTRIBUTES);
sa.lpSecurityDescriptor = NULL;
sa.bInheritHandle = TRUE;
if (!CreatePipe(&hRead,&hWrite,&sa,0))
{
return FALSE;
}

STARTUPINFO si;
PROCESS_INFORMATION pi;
si.cb = sizeof(STARTUPINFO);
GetStartupInfo(&si);
si.hStdError = hWrite;
si.hStdOutput = hWrite;
si.wShowWindow = SW_HIDE;
si.dwFlags = STARTF_USESHOWWINDOW | STARTF_USESTDHANDLES;
//关键步骤，CreateProcess函数参数意义请查阅MSDN
if (!CreateProcess(NULL, EXECDOSCMD
,NULL,NULL,TRUE,NULL,NULL,NULL,&si,&pi))
{
return FALSE;
}
CloseHandle(hWrite);

return TRUE；
}
