[Help Needed] Require Correct Input and execute bat

[Bobalandi]

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

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?

[chemicalNova]

..yes.

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.

thanks a bunch...

[Bobalandi]

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

[Bobalandi]

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

[chemicalNova]

Show your code.

chem

[Bobalandi]

Here you go:

#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;
}

[chemicalNova]

Try using a string:

// char pass[9];
string pass;

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

chem

[Bobalandi]

hmmm, string desnt even work with the compiler..

[chemicalNova]

Oh.. you need to include <string>.

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

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

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...

[Bobalandi]

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

[chemicalNova]

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

[Bobalandi]

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

[chemicalNova]

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

#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

[Bobalandi]

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?

[chemicalNova]

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

[Bobalandi]

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