error message appears when function is called

[babygal]

An error message prompt appears when function, processInputData(param1, param2, ....) is called.
The application exits when 'Don't Send' button on the message prompt is clicked on.
How do I resolve this issue?

Here is the code:

New::New(QWidget *parent) :
    QDialog(parent)
{
    okButton = createButton(tr("&OK"), SLOT(messageOk()));
 
    createCMRFilesMessageGroupBox();
    createEDMessageGroupBox();
    createESMessageGroupBox();
 
    createmainLayout();
 
    setWindowTitle(tr("New Case"));
    resize(450, 100);
}
void New::messageOk()
{
 
    QMessageBox::about(this,tr("OK clicked"),tr("OK"));
    processInputData(endocardialfileName.toAscii(), //convert 'QString' to 'const char*'
                                  epicardialfileName.toAscii(),    //convert 'QString' to 'const char*'
                                  1,
                                  1.1,
                                  1.1,
                                  1,
                                  1.1,
                                  1.1);
 
 
}

New::New(QWidget *parent) :
    QDialog(parent)
{
    okButton = createButton(tr("&OK"), SLOT(messageOk()));

    createCMRFilesMessageGroupBox();
    createEDMessageGroupBox();
    createESMessageGroupBox();
    
    createmainLayout();

    setWindowTitle(tr("New Case"));
    resize(450, 100);
}
void New::messageOk()
{

    QMessageBox::about(this,tr("OK clicked"),tr("OK"));
    processInputData(endocardialfileName.toAscii(), //convert 'QString' to 'const char*'
                                  epicardialfileName.toAscii(),    //convert 'QString' to 'const char*'
                                  1,
                                  1.1,
                                  1.1,
                                  1,
                                  1.1,
                                  1.1);
