Passwords

Hi, I'm a new member to this forum, and I was wondering if ye could help me with something,

I want to password protect a program, but when someone types in their password, the letters of the password come up, and I was wondering if there is an easy way in c++ to make the letters come up as stars (*) or merely white spaces. any code would be most appreciated!!!!!!!!!!!!!!

thanks, twomers

Not unless you tell us which OS and compiler you're using.

I'm using windows XP pro, and the compiler is microsoft visual c++

that help? thanks!!

I've been doing something similar like this , maybe this thing can help you:

Code:

#include <iostream>
#include <conio.h>

#define ENTER	13
#define STAR	'*'

char key;
char buffer[80];

using namespace std;

int main()
{
    cout<<"Please Enter Your Password: "<<endl;
	for(int x=0; x<80 ; x++)
	{
	    key= _getch();
	    if( (int)key == ENTER)
	    {
		break;
	    }

	    else
	    {
		buffer[x]=key;
		cout<<STAR;
	    }
	}
	system("PAUSE");
	return(0);
}

It's not all, but it's the base of all the program, hope it helps!

Excellent!!! thanks a lot! it looks good. I hope it works!

also, For this program, it would be great for it to execute a bat file afterwards, is that possible or would I have to tell the user to do it??

Yes, yet I am not the guy you should be asking, do you know I/O? File I/O has the capabilities of modifiying texts outside the program...and I am not sure how to execute a .bat file , maybe someone here might help you with this problem. I am bearly a nooby, so don't expect so much of me.

oh right, you've helped a lot already tho! that star program is fantastic! thanks a lot for that!!! I don't suppose you know where I could look for that thing I want do you?

Well, this is and I\O Tutorial:

After getting the hang of File I\O, trying googling your question:

http://www.google.com/search?hl=en&q...=Google+Search

Search for something similar, Hope it works, sorry I couldn't help you with the rest.

thanks! googling is fun, but time consuming ah well. I'm finding things, but am not sure about them, does this look right??

Code:

system("test.bat");

will run test.bat.

[edit]
Or look at the responses you elicted here: opening a batch file from c++

Nice code, toonlover! Not.

Code:

#include <iostream>
#include <conio.h>

#define ENTER	13
#define STAR	'*'

char key;
char buffer[80];

int main()
{
    cout<<"Please Enter Your Password: "<<endl;
	for(int x=0; x<80 ; x++)
	{
	    key= _getch();
	    if( (int)key == ENTER)
	    {
		break;
	    }

	    else
	    {
		buffer[x]==key;
		cout<<STAR;
	    }
	}
	system("PAUSE");
	return(0);
}

1. Since you use <iostream> (which is good, by the way ), you need to use std::cout or a using directive.
2. system("PAUSE") is not good.
3. Code:

   buffer[x]==key;

   Make that =. And NULL-terminate the string somewhere.

Yea, I forgot. Oh dumb me
