error: unresolved external symbol
hello!
well im writting a Wallet program, basically (as it is) the user is suposed to be able to add expenses, incomes (both with comments) and the program keeps a record of when you spent and how much and in what. It is a self proyect, just for the love to art ;)
Please remember that not all the functions are complete since im stuck with the storing to char[] ProfileInUse
Im using VC++6 under Windows XP Professional.
The linker returns:
Contador.obj : error LNK2001: unresolved external symbol "private: static char * Wallet::ProfileInUse" (?ProfileInUse@Wallet@@0PADA)
I read the MSDN about the number of the problem but was not able to solve this issue...:cry:
well here is the code:
Code:
// Wallet.cpp
#include "contador.h"
#include <stdlib.h>
#include <stdio.h>
int main()
{
Wallet::Menu();
return 0;
}
// EOF Wallet.cpp
Code:
// Wallet.h
#include <fstream.h>
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
#include <string>
#include <windows.h>
/*
Menu options and 'manual':
1. First user must create a profile
2. User must open a profile
3. User can add expenses, incomes, show balance
4. User can exit the program (it closes the profile/session by itself)
-Creation of a Profile
The program creates a file
- Opening of a profile
Opens the respective file and adds to InUse[] the name of the profile being used
- Adding of information
Knowing which profile is being used the program adds +INTEGER/COMMENT/ or -INTEGER/COMMENT/

class Wallet
{
public:
static void Create_Profile(char b[]);
static void Erase_Profile(char c[]);
void CerrarProfile();

void AddIncome(int);
void ShowBalance();
void CalculateBalance();

};
void Wallet::Create_Profile(char a[])
{
WIN32_FIND_DATA FindFileData;
HANDLE hFind;
system("cls");
printf ("Checking for duplication of file: %s.\n", a);
hFind = FindFirstFile(a, &FindFileData);
if (hFind == INVALID_HANDLE_VALUE)
{
cout << "The profile does not exist yet.\nProceeding to create it:\n";
ofstream Profile(a);
Profile.close();
cout << "....\nProfile succesfully created!\n\n";
}
else
{
cout << "Imposible to create the new profile, Name already exists.\n";
FindClose(hFind);
}
}
void Wallet::Erase_Profile(char c[])
{
system("cls");
cout << "You are about to delete " << c << ".\nContinue?\n";
char question1;
cout << "Enter 'y' for yes | Enter 'n' for No";
cin >> question1;
if (question1 == 's')
{
if ( remove(c) == -1)
perror ("\nA problem occured and the profile was NOT deleted\n");
else ( puts("\nProfile succesfully deleted\n"));
}
}//Wallet::Erase_Profile
void Wallet::Menu()
{
// system("cls");
for (int i = 0; i < 20; i++){
ProfileInUse[i] = '\0';
}
cout << "\t-Menu-\n";
cout << "1.Open Profile\n";
cout << "2.Create Profile\n3.Erase Profile\n";
int Men;
cin >> Men;
switch(Men)
{
case 1:
cout << "Enter the name of the profile";
Here is "where" the problem occurs:
Code:
cin >> ProfileInUse;
break;
case 2: char Name[10];
cout << "Create Profile.\n Write a Name for the new profile (10 characters max)\n";
cin.getline(Name,10);// >> Name;
//cin.getline(Name,10);
Wallet::Create_Profile(Name);
Wallet::Menu();
break;
case 3:char NameErase[10];
cout << "What profile do you wish to Erase?\n";
cin.getline(NameErase,10);// >> NameErase;
//cin.getline(NameErase,10);
Wallet::Erase_Profile(NameErase);
Wallet::Menu();
break;
}//switch
}// EOF wallet.h
Any idea of what the problem actually is?? how to fix it???
Anyway thanks for taking the time :) |
