CreateProcess 执行nc命令 nc 127.0.0.1 3333 > g:/img/data.img 不成功

[www2t]

如题CreateProcess执行nc 127.0.0.1 3333 > g:/img/data.img命令 总是无法生成data.img文件，求帮忙！

STARTUPINFO si={sizeof(si)};			
		si.wShowWindow = SW_SHOW;		

		PROCESS_INFORMATION pi;
		ZeroMemory(&pi,sizeof(pi));		
		TCHAR cmdline[] =TEXT("..\\adbhelp\\nc 127.0.0.1 3333 > g:/img/data.img"); 
		if (!CreateProcess(NULL,cmdline,NULL,NULL,FALSE,NULL,NULL,NULL,&si,&pi))
		{
			MessageBox(m_hParent,L"Error on CreateProcess()!",L"提示",MB_OK);
			return NULL;
		}
		else
		{
			CloseHandle(pi.hProcess); 
			CloseHandle(pi.hThread); 
		}

用绝对路径，同时用双引号把路径包含起来

CreateProcess直接执行重定向到文件的命令行指令是有问题的，可以创建一个文件并把文件句柄付给si.hStdOutput ，更改标准输出到文件即可

hOpenFile = CreateFile(m_strImagePath,
						GENERIC_WRITE | GENERIC_READ, 
						FILE_SHARE_READ,
						&saFile,
						CREATE_NEW,
						NULL,
						NULL);
STARTUPINFO si={sizeof(si)};
si.hStdOutput = hOpenFile;
si.wShowWindow = SW_HIDE;
si.dwFlags = STARTF_USESHOWWINDOW | STARTF_USESTDHANDLES;

PROCESS_INFORMATION pi;
ZeroMemory(&pi,sizeof(pi));
TCHAR* cmdline=StringToChar(str);
if (!CreateProcess(NULL,cmdline,NULL,NULL,TRUE,NULL,NULL,NULL,&si,&pi))
{
.....
}
WaitForSingleObject( pi.hProcess ,INFINITE );  
CloseHandle ( pi.hProcess );  
CloseHandle ( pi.hThread );  
CloseHandle(hOpenFile);
