Password gate

How do you make a password gate in a windows program?

What's a password gate?

I'm just going to guess what you mean by 'password gate'..
Here is some code I just threw together as an example of console password input. This code will most likely contain bugs, but it should give you the general idea.

Code:

#include <iostream>
#include <conio.h>
using namespace std;

bool GetPassword(char * CorrectPass, int PassMaxLength)
{
	char * str = new char[PassMaxLength+1];
	char chr;
	int InputCounter = 0;
	
	do	{
		chr = getch();
		if(chr == (char)8)
		{
			if(InputCounter == 0) continue;

			InputCounter--;
			cout << (char)8 << " " << (char)8;
		}
		else if(chr != '\r')
		{
			str[InputCounter] = chr;
			cout << "*";
			InputCounter++;
		}
	}
	while(InputCounter < PassMaxLength && chr != '\r');
	str[InputCounter] = '\0';

	if(strcmp(str,CorrectPass) == 0)
	{delete[] str;  return true;}
	
	delete[] str;
	
	return false;
}

int main()
{
	cout << "Password: ";
	if(GetPassword("password",100) == true)
		cout << "\nCorrect Password!" << endl;
	else
		cout << "\nYou Suck!" << endl;
	
	return 0;
}

It's quite possible I missunderstood what 'password gate' meant, if I did, just ignore this whole post

r1ck0r has the right idea, but it's not windows, it's DOS.

Below is an example of a password gate.

There is a 'Windows Programming' section on this forum, this question would've been more suited there. Anyway, this link: http://www.winprog.net/ will give you an introduction into windows programming.
