Is this possible?

Hey, I am new to visual basic, and taking a class on it in school.

Anyway, I was wondering if it was possible to have the user input data, and have the data SAVED to a file, so it could be resurrected later.

Help is appreciated. BTW, I plan on staying on this forum for a while, and hopefully getting good.

/me looks at sign above door

"Visual C++ Programming"

yep, thought so.

:p

(yes it's possible)

Oh, and btw, if this is possible, could someone give me the coding for it? I am very new, and most likely would understand all of the terms within the code.

BTW, a small prize may be awarded. :)

perhaps you misunderstand, this is a C++ forum, not a VB one.

OH yeah, very sorry. I meant Visual Studios! I always get those two mixed up.. =/

Nevermind, I figured it out, and it is fairly simple.

My next challenge is this: I need to figure out a way to convert letters into asterisks when the user types in any type of character. Is this possible?

In C/C++ you can use cin, cout ( in iostream header) to have use input. And you can write your data to file by using ifstream or ofstream (in fstream header).

Btw, you can read more in C/C++ books. Hope it help.

Thanks for your input Z, however I have already figured out how to do it. Although your way seems much more simple; are you sure it works? Anyhow, this is the code I came up with:

Code:

---

#include <iostream>
using namespace std;
int main()
{
    char message[20];
        FILE *test = fopen("test.txt", "w");
        cout << "message: ";
        cin >> message;
        fprintf(test, "&#37;s\n", message);
}

---

*I took the code from a much more complex program, and reduced the complexity significantly.*

As well, my current issue is figuring out a way to convert characters into asterisks like a password field.

hi,

Code:

---

#include <iostream>
using namespace std;
int main()
{
    char message[20];
        FILE *test = fopen("test.txt", "w");
        cout << "message: ";
        cin >> message;
        fprintf(test, "%s\n", message);
}

---

:) It's ok.

And "asterisks like a password field."

I wonder whether you use console application or windows application.

if you are in console application, maybe you can do it like that :

Code:

---

void input()
{
  char c;
  char pass[100];
  int i = 0;
  printf("Your Pass: ");
  c = getchar();
  while(c != 13 && i <100)
 {
    printf("*");
    pass[i++] = c;

  }
 
}

Hmm, I tested it, but it does not work. It only prints 100 asterisks after you input the password.

I was thinking about using a while statement..but I do not think it is possible.

Thanks a bunch though for your contribution. :)

Well, I figured this one out on my own as well, if anyone wants to check it out, here it is:

Code:

---

#include <iostream>
#include <string>
#include <conio.h>
using namespace std;
void InputPassword(string &value);
int main(void)
{
    string pass;
    cout <<"Please enter your password: ";
        InputPassword(pass);
    cout << endl << endl;
    cout << pass << endl << endl;
}
void InputPassword(string &value)
{
        char key;
        do
        {
                key = getch();
                value.push_back(key);
                std::cout << "*";
        }while(key != '\r'); //Quit if Enter is Pressed
}

Yep..the good 'ol do-while.
