如何重定向DOS窗口里的输出内容至我的程序界面里？

[incats]

用CreateProcess 调用了一个DOS下的命令，希望将它运行中的所有提示信息都在我的界面里反应。如何实现？ 改变了CreateProcess里的StartupInfo那一选项也不行。
BOOL CMyTestDlg::RunAndRedirectOutput(CString CommandLine, CString OutputFile)
{
STARTUPINFO StartupInfo;
PROCESS_INFORMATION ProcessInfo;
SECURITY_ATTRIBUTES SecAtrrs;
HANDLE hAppProcess, hAppThread, hOutputFile;

TRY
{
memset(&SecAtrrs, 0, sizeof(SecAtrrs));
SecAtrrs.nLength = sizeof(SecAtrrs);
SecAtrrs.lpSecurityDescriptor = NULL;
SecAtrrs.bInheritHandle = TRUE;

hOutputFile = CreateFile( (LPCTSTR)OutputFile,
GENERIC_READ|GENERIC_WRITE,
FILE_SHARE_READ|FILE_SHARE_WRITE,
&SecAtrrs,
CREATE_ALWAYS,
FILE_ATTRIBUTE_TEMPORARY,
0);

if (hOutputFile != INVALID_HANDLE_VALUE)
{
memset(&StartupInfo, 0, sizeof(StartupInfo));
StartupInfo.cb = sizeof(StartupInfo);
StartupInfo.dwFlags = NULL;//STARTF_USESHOWWINDOW|STARTF_USESTDHANDLES;
StartupInfo.wShowWindow = SW_NORMAL; //HIDE;
StartupInfo.hStdOutput = hOutputFile;
StartupInfo.hStdError = hOutputFile;

if(CreateProcess(NULL,
(LPTSTR)(LPCTSTR)CommandLine,
NULL,
NULL,
TRUE,
CREATE_NEW_CONSOLE|REALTIME_PRIORITY_CLASS,
NULL,
NULL,
&StartupInfo,
&ProcessInfo))
{
WaitForSingleObject(ProcessInfo.hProcess, INFINITE);
hAppProcess = ProcessInfo.hProcess;
hAppThread = ProcessInfo.hThread;
}
}
}
CATCH(CException, e)
{
char lpError[1000];
int nMaxError = 1000;
e->GetErrorMessage(lpError, nMaxError);
MessageBox(lpError);
}
END_CATCH

if (hOutputFile) CloseHandle(hOutputFile);
if (hAppThread) CloseHandle(hAppThread);
if (hAppProcess) CloseHandle(hAppProcess);

return TRUE;

}

void main()
{
printf("message");

HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE);

COORD dwPos = {0, 0};
TCHAR szOut[255];
DWORD cReadNumber;
ReadConsoleOutputCharacter(hOut, szOut, 255, dwPos &cReadNumber);

printf("This string of read:%s\n", (char*)szOut);
}

说笨方法的那位，谢谢你！ 但不是我想要的。

我需要的是重定向，不是从CONSOLE再读取。

那位说命名管道的，请提供链接，谢谢！

再有， CREATEPROCESS里那个STARTUPINFO的成员变量，按说明来看，应该能够实现这一需求的，不知为何不行？

StartupInfo.hStdOutput = hOutputFile;
要使其生效必须指定StartupInfo.dwFlags = STARTF_USESTDHANDLES;

入口参数是一个DOS命令，执行完成后，从通道中读取出显示内容，显示到对话框的编辑窗内
void CKeyAssDlg::ExecuteUserCommand(LPCTSTR lpszCmd)
{
SECURITY_ATTRIBUTES sa;
HANDLE hRead,hWrite;
CString strCmdInfo;
char buffer[10240] = {0};
DWORD bytesRead = 0;
DWORD dwRead = 0 ;
char szCmd[256];
int nLen = 0;
strcpy(szCmd,"cmd.exe /a /s /c ");
strcat(szCmd,lpszCmd);
strCmdInfo.Format("KeyAss:>%s\r\n",lpszCmd);
m_strCmdInfo += strCmdInfo;

strCmdInfo.Empty();

sa.nLength = sizeof(SECURITY_ATTRIBUTES);
sa.lpSecurityDescriptor = NULL;
sa.bInheritHandle = TRUE;
if (!CreatePipe(&hRead,&hWrite,&sa,0))
{
strCmdInfo = "\n创建通道失败...";
m_strCmdInfo += strCmdInfo;
goto END_EXEC;
}

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;
if (!CreateProcess(NULL,szCmd,NULL,NULL,TRUE,NULL,NULL,NULL,&si,&pi))
{
strCmdInfo.Format("执行程序 %s 失败\r\n",lpszCmd);
m_strCmdInfo += strCmdInfo;
goto END_EXEC;
}
CloseHandle(hWrite);

while (1)
{
if( dwRead > 10239 )
break;
Sleep(200);
if (ReadFile(hRead,&buffer[dwRead],10239-dwRead,&bytesRead,NULL) == NULL)
break;
dwRead += bytesRead;
bytesRead = 0 ;
strCmdInfo += buffer;
m_strCmdInfo += strCmdInfo;
m_ctrlCmdInfo.SetWindowText(m_strCmdInfo);
nLen = m_strCmdInfo.GetLength();
m_ctrlCmdInfo.SetSel(nLen,nLen);
}
CloseHandle(hRead);

END_EXEC:
m_ctrlCmdInfo.SetWindowText(m_strCmdInfo);
nLen = m_strCmdInfo.GetLength();
m_ctrlCmdInfo.SetSel(nLen,nLen);

m_strCmd.Empty();
SetDlgItemText(IDC_COMMAND,m_strCmd);
}

自己做一个DOS虚拟机

[hslinux]

笨办法：aa.exe >> aa.txt，，先输出到文件，再读文件显示出来。。。。。。

[HuWenjin]

用命名管道

网上有现成的例子

[mynamelj]

BOOL ReadConsoleOutputCharacter(
HANDLE hConsoleOutput,
LPTSTR lpCharacter,
DWORD nLength,
COORD dwReadCoord,
LPDWORD lpNumberOfCharsRead
);
