QProcess StdErr signal question

[devx]

Im using QProcess (Qt 4.5) to access console (cmd.exe ) in Windows XP.
Is has properly connected stdout/stderr/terminate signals.

When i send something to its write channel it seems to work correctly. CMD responds as it sholud (for ex: dir command,). Im able to read output from stdout channel (result: directory list).
The problem is when i send some garbage (for ex "aksfvakhv"). Console program sends proper stderr output text ("Command not found" or something) and then it terminates! So I need to restart it again. I tried it with another console program and it behaves the same way.

Im using readAllStandardError() to do read stderr channel.
Process sends terminate signal (ExitStatus: NormalExit).



void JGI::readStdError()
{
QByteArray errbuffer=cmdProc->readAllStandardError();
ui->cmdStdError->setText(QString::fromLocal8Bit(errbuffer));
}


Whats wrong?

Signals are connected properly. Checked n times.

I read your post twice and still am not sure what your problem is. Can you perhaps rephrase it?

[devx]

The problem is that console process launched by QProcess class terminates itself immediately after sending stderror text message (through stderror channel ofc.).

What process are you running? Post some code.

It sounds completely normal however. If you post garbage, it complains and terminates. Whats wrong with that?

Normal? For a win cmd.exe ?

It should work like this
----begin
c:\> dir [enter] / stdin <-
dir1 blebelbel / stdout ->
dir2 blebelbel / ..
dir3 blebelbel / ..
....
c:\> garbage [enter] /stdin <-
Unknown command.... /stderr ->
c:\> dir [enter] /stdin <-
dir1 blebelbel /stdout ->
dir2 blebelbe l /..
dir3 blebelbel /..
-----end

But works like this:
----begin
c:\> dir [enter] / stdin <-
dir1 blebelbel / stdout ->
dir2 blebelbel / ..
dir3 blebelbel / ..
....
c:\> garbage [enter] / stdin <-
Unknown command.... / stdout ->
[cmd.exe terminates] / ??? o.O :eek:
-----end

// edit:

Problem solved, it was external program setup fault. Damn.
Topic can be removed, because its a trash...
