Hello, and thanks for reading!
I have this class CLogger. It has two variables which is: "std::string filename" and "std::ofstream file". I also have two methods, which is: "virtual void OpenLogFile()" and "virtual bool WriteToFile(std::string)".
In my method "OpenLogFile()" I need to access the member variable "file", and then later, in my method "WriteToFile(std::string)" I need to access that variable once again because I'm writing to it. The thing is, I get an error saying:
'file' is incomplete type
Here's the code:
CLogger.h
#ifndef CLOGGER_H
#define CLOGGER_H
class CLogger //Logger class
{
public:
//variables
std::string filename; //Filename of the log file
std::ofstream file; //file object
//methods
virtual void OpenLogFile(); //This is called at the start...
virtual bool WriteToFile(std::string); //Writes a string to a file
};
#endif
CLogger.cpp
#include <iostream>
#include <fstream>
#include "CLogger.h"
void CLogger::OpenLogFile()
{
file.open(this->filename.c_str(), std::ios::app); //Open file for writing
}
bool CLogger::WriteToFile(std::string text) //WriteToFile method, writes the string to the file
{
if(file.is_open()) //If the file is opened
{
//Write to file
file << text << "\n";
}
else //if the file is not opened
{
file.close(); //close the file
return false; //return failure
}
file.close(); //Close the file
return true; //Writing succeded, return success.
}
main.cpp
#include <iostream>
#include "CLogger.h"
CLogger* Logger = new CLogger();//Create a new log object
int main()
{
Logger->filename = "log.txt";//Set the logfile's name to "log.txt"
Logger->OpenLogFile(); //open the logfile for writing
Logger->WriteToFile("Starting log file..."); //write to file
Logger->WriteToFile("Hello world"); //Write "hello world" to the file
}
Thanks for any help! [smile]
Hope I was helpful. And thank you if you were!
