QString, how to delete new lines

[lyuts]

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);

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()
}
