Pipe from GUI app to console process

Your question is a bit unclear? What folder, and what dialog box are you referring to?

Hello everybody!
I've been working for some hours in a project of a GUI app that runs a console app (ssh) in background. Well, I've been using many examples of code from here (codeproject) and from the internet, but I had aways stoped at the same error. Maybe someone can give me some help... here is what happens:
I create the pipes and begin the execution of the program... everything goes fine, the ssh program ask for the password, and then I use WriteFile to send it the password. >Crash!<
It continues the execution and do not even try to validate the password Sigh | :sigh:

I'll put some code here:

//creating pipes
if(!CreatePipe(&hChildStdoutRd, &hChildStdoutWr, &secattr, 0))
     AfxMessageBox("Error in pipe Out");

SetHandleInformation(hChildStdoutRd, HANDLE_FLAG_INHERIT, 0);

if(!CreatePipe(&hChildStdinRd, &hChildStdinWr, &secattr, 0))
     AfxMessageBox("Error in pipe In");

SetHandleInformation(hChildStdinWr, HANDLE_FLAG_INHERIT, 0);

/////////////////////////////////////////////////////////////
// In another thread, I started the app. The pipes stay in a object that is
// passed through parameter to the thread execution.
STARTUPINFO sInfo; 
ZeroMemory(&sInfo,sizeof(sInfo));
PROCESS_INFORMATION pInfo; 
ZeroMemory(&pInfo,sizeof(pInfo));
sInfo.cb=sizeof(sInfo);
sInfo.dwFlags |= STARTF_USESTDHANDLES;
sInfo.hStdInput = cssh->hChildStdinRd; 
sInfo.hStdOutput = cssh->hChildStdoutWr; 
sInfo.hStdError = cssh->hChildStdoutWr;

//In the same thread, I read the first line of execution...
CloseHandle(csftp->hChildStdoutWr);

for( ;; ) {
 if(!ReadFile(csftp->hChildStdoutRd, buf, 100, &dwRead, NULL) || dwRead == 0)
   break;
   
   buf[dwRead] = '\0';
   strAux = buf;
   cssh->ShowText(strAux);
}

// The password is typed in a Edit (for test porpouse only), and a try this code:
strcpy(strPass, szBuf);

if(!WriteFile(hChildStdinWr, szBuf, strPass.GetLength() ,&dwWritten, NULL))
   AfxMessageBox("Error in hChildStdinWr");

if(!CloseHandle(hChildStdinWr))
   AfxMessageBox("Error in hChildStdinWr");

After execute the code above, the ssh app runs all the authentication with failure

<br />
user@host's password: <br />
user@host's password: <br />
user@host's password: <br />
user@host's password: <br />
user@host's password: <br />
Using username "user".<br />
Access denied<br />
Access denied<br />
Access denied<br />
Access denied<br />
Access denied<br />
Fatal: Server sent disconnect message<br />
type 2 (SSH_DISCONNECT_PROTOCOL_ERROR):<br />
"Too many authentication failures for user"<br />

Any help, is welcome Smile | :)

cheers!

Hi David, thanks for your quick reply.
Yes, I read those articles. But I still have problems to 'adapt' to a GUI app... they all implement console applications.

thanks anyway

Hi Dadiv, All.

I found the problem.

if(!CloseHandle(hChildStdinWr))
  AfxMessageBox("Erro ao fechar o handle hChildStdinWr");

This handle, must not be close.
Thanks all for the atention,
Regards! Smile | :)

Regardign IPAddress Retrieval

1)upload ur code somewhere, someone may download and test it for u.
2)u do need to study a sample carefully.

at least, i don't think code like this meaningful:
sInfo.hStdInput = cssh->hChildStdinRd;

before u call
CreatePipe() and CreateProcess()

Hai,

How can we retrieve the IPAddress from a DNS Site Name. How can we fetch the information regarding a particular site using its IP Address. So Please give a reply for me.

Use gethostbyname().

Yes, I do (have 1.52c).

mwhahahah, nice try.

even if you did get a copy (which is not legal), i doublt you could do something powerful since the standard is far from this implementation now...

Daniel Zaharia11-Apr-06 3:08

11-Apr-06 3:08

I don't need something powerfull.
The problem is that that i need it to program an old barecode scaner, and it must be at most MV C++ 1.5 (16 bits??)

David Crow11-Apr-06 3:00

11-Apr-06 3:00

Why would I want to do that? It would be illegal. Roll eyes | :rolleyes:

The firm where i work it is member of Microsoft Partnership Program (about the license) , but thy only have on their site M V C++ 1.52 (not professional)

True, it has not been available for quite some time now. You might could get it from pricewatch.com[^] or the like.

Daniel Zaharia wrote:

So what is the difference between v1.5 and v1.52?

The difference must be between MV C++1.5 and MV C++ 1.5 Professional.
I the first does not support development of DOS applications

Are you needing to modify an existing project, or create a new one? If the latter, could you use VC++ v6?

Which i think takes you back to v1.0.

DR DOS (not MS DOS!)

It is about an barecode scanner from Symbol. They have their own operating system. They provide some examples .C and .exe. I need to modify a bit the sample file and compile it to .exe. My .exe does not work.(even if i copile exactly the same file that generated their exe). Of course, customer support is off.
