29: error: ‘string’ does not name a type

[joebar]

Hi,

when try to compile my program I get the following message for this header file

#ifndef SENDSMS_H
#define SENDSMS_H

#include "ui_sendSMS.h"
#include <string>


class sendSMS : public QMainWindow, public Ui::MainWindow{
	Q_OBJECT

public:
	sendSMS (QMainWindow *parent = 0);
	~sendSMS();
private slots:
	void slotClose();
	void calcChar();
	void slotSend();
	QString clean_string(QString);
	QChar get_param(QString, int);
	QString get_param_value(QString, int);
	void process_line(QString);
	void read_config_file();

private:
	int maxChar;
	QString param_filename;
	string username;
	string password;
	string sourceno;
	
};

#endif

Ignore all the "Q" things, thats something Qt specific. int works fine, but not string. I have the string header included. I guess it is rather simple what is wrong....

Thanks,
J.
