Something like this

yourString.replace(QString("\n\n"), QString("\n"));

yourString.replace(QString("\n\n"), QString("\n"));

Hi,

it dosent work

same result:

QString information = process->readAllStandardError();
information.replace(QString("\n\n"), QString("\n"));

QString information = process->readAllStandardError();
information.replace(QString("\n\n"), QString("\n"));

How often is readAllStandardError() called? It might be that it reads and gets "Connecting to STCHPS426..." then it is called several times but nothing is in StandardError, that's why you get newlines.

One of the possible solutions is to connect a readyReadStandardError() signal of QProcess to a slot, which will call readAllStandardError().

yes, im calling every 21 milisecond

QString information = process->readAllStandardError();
	QString defaulttext1 = "PsExec v1.94 - Execute processes remotely";
	QString defaulttext2 = "Copyright (C) 2001-2008 Mark Russinovich";
	QString defaulttext3 = "Sysinternals - www.sysinternals.com";
 	information.replace(defaulttext1, "");
 	information.replace(defaulttext2, "");
 	information.replace(defaulttext3, "");
 	information.replace("with error code 0.", "");
 	information.replace(QString("\n\n\n\n\n"), QString("\n"));
 	ui.information_te->setText(ui.information_te->toPlainText() + information);

QString information = process->readAllStandardError();
	QString defaulttext1 = "PsExec v1.94 - Execute processes remotely";
	QString defaulttext2 = "Copyright (C) 2001-2008 Mark Russinovich";
	QString defaulttext3 = "Sysinternals - www.sysinternals.com";
 	information.replace(defaulttext1, "");
 	information.replace(defaulttext2, "");
 	information.replace(defaulttext3, "");
 	information.replace("with error code 0.", "");
 	information.replace(QString("\n\n\n\n\n"), QString("\n"));
 	ui.information_te->setText(ui.information_te->toPlainText() + information);

I dont know how to delete these new lines

Ok, then try to do this.

1. get string from standardError
2. check, if it is not empty (with isEmpty()), then do ui.information_te->setText(ui.information_te->toPlainText() + information).

Why do you call it every 21 milisecond?

Would not it be better if you do

connect(yourProcess, SIGNAL(readyReadStandardError()), this, SLOT(readError()));
connect(yourProcess, SIGNAL(readyReadStandardOutput()), this, SLOT(readOutput()));
...
 
void yourClass::readError()
{
// call readAllStandardError()
}
 
void yourClass::readOutput()
{
// call readAllStandardOutput()
}

connect(yourProcess, SIGNAL(readyReadStandardError()), this, SLOT(readError()));
connect(yourProcess, SIGNAL(readyReadStandardOutput()), this, SLOT(readOutput()));
...

void yourClass::readError()
{
// call readAllStandardError()
}

void yourClass::readOutput()
{
// call readAllStandardOutput()
}

Hi,

no, same result with new lines

if(!information.isEmpty()) 
	{	
 	ui.information_te->setText(ui.information_te->toPlainText() + information);
 	}

if(!information.isEmpty()) 
	{	
 	ui.information_te->setText(ui.information_te->toPlainText() + information);
 	}

Try the way with signals and slots as in my previous post.
