    Hi, how would I remove all carriage returns , tabs, line feeds ect from a QString. I just want all character and number data.

    Thanks

      One way would be to use QString::replace(), use a QRegExp to find the characters/character sequences you mention, and replace them with "".

        "QString::remove()":http://doc.qt.nokia.com/4.7-snapshot/qstring.html#remove would be equivalent, too. You also might consider the possibility of using "QString::simplified()":http://doc.qt.nokia.com/4.7-snapshot/qstring.html#simplified to cull out a lot of extraneous white space first, if it would help in building your QRegExp.
