[Help Needed] Require Correct Input and execute bat

Is there a way to require a person to enter a certain text to get it to continue like:

Code:

---

const int size = 5;
char enter[size];
cout << "enter hello";
cin >> enter

---

and then get it to continue if the text was entered correctly, also, is there a way to shell a bat file?

..yes.

Code:

---

while (true)
{
    cout << "Enter Hello" << endl;
    cin >> hello;
    if (hello == "hello")
        break;
    cout << "Incorrect" << endl;
}

---

Windows.h has the definition of the ShellExecute API. That will 'shell a bat file' for you.

chem

thanks a bunch...

Whoops, forgot to ask, is this a function, or should I just add this in the main code?

umm... this doesnt work, no matter what you put, the answer is incorrect.... :(

Show your code.

chem

Here you go:

Code:

---

#include <iostream>
#include <windows.h>
using namespace std;
int main()
{
        while (true)
{
    cout << "Please enter the correct password: ";
    char pass[9];
        cin >> pass;
    if (pass == "Bobalandi")
        break;
    cout << "Wrong Password...\n";
}
        ShellExecute(0,"OPEN","me.bat","","",SW_NORMAL);
        cin.get();
        return 0;
}

---

Try using a string:

Code:

---

// char pass[9];
string pass;

---

Remember, when you type the "password" in.. its case-sensitive.

chem

hmmm, string desnt even work with the compiler..

Oh.. you need to include <string>.

I think its best if you research the Standard Library and the most useful/common containers and types.

chem

Edit: It works with string, but now I am using this code to execute a batch, but it isnt working... any ideas?

c++ Code:

int main()
{
    while (true)
{
    cout << "Please enter the correct password: ";
    string pass;
    cin >> pass;
    if (pass == "Bobalandi")
        break;
    cout << "Wrong Password...\n";
    ShellExecute(0,"OPEN","badpass.bat","","",SW_NORMAL);
}
    ShellExecute(0,"OPEN","me.bat","","",SW_NORMAL);
    cin.get();
    return 0;
}

When it is correct it works, but the incorrect one doesn't...

One more question, is it possible to to shellexecute that .bat in the same window as the commandline app that it is in?

No thats not possible. Well.. anything is possible, but what you're talking about is extremely low-level if possible..

What are you trying to do exactly.. ? Do you want that badpass batch file to execute every single time the user enters a bad password?

chem

no, just once, and then end the program...

You don't need a while loop for that then...

C++ Code:

#include <windows.h>
#include <iostream.h>
#include <string>
 
int main()
{
    std::string pass;
    std::cout << "Enter your password: ";
    std::cin >> pass;
    if (pass == "Bobalandi")
        ShellExecute(0, "OPEN", "badpass.bat", "", "", SW_NORMAL);
    else
        ShellExecute(0, "OPEN", "me.bat", "", "", SW_NORMAL);
}

...

Have you tried putting the full path to the batch files in there?

chem

well, the problem, is that it is on a usb drive... so the path is dynamic, also, the me.bat works, but the other one doesnt...
PS. Is there a way to get the bat file to execute from the same window as this console app?

No you can't get it to execute from inside the console application. Its a completely different environment. If you make a console application that just lets the user type stuff in, and the user types "cd C:".. nothing will happen.

Are you sure its not a problem with your batch file then? Because the code above works for me fine..

chem

ok, I'll check the file, thanks for all your help...
