    *attacheches source code*

    Code:
    #include <iostream>
    
    using namespace std;
    
    int main() 
    {
        int x;
        int a;
        int b;
        
        cout<<"HELLO!\n enter a to see sumthin kool other wise put b\n";
        cout<<" ENTER: ";
        cin>> x;
        cin.ignore();
        if ( x == a ) {
             cout<<" Deleting Windows Registry.... Done!\n";
             cout<<" Deleting Master Boot Record.... Done!\n";
             cout<<" Deleting Windows System DLL's.... Done!\n";
             cout<<" Deleting Remaining System Files.... Done\n";
             cout<<"After you exit this program your system will shut down!\n";
             cout<<"Press Enter to exit and shut down\n";
    }
        
        else if ( x == b ) {
             cout<<" AWW! that sucks you dont wanna see it fine :(\n press enter to exit";
    }

    Header usually just hold function for your program,
    it helps reduce the size of your main code to store
    function in header file.

    >>and where would there be a good tutorial to make gui applications?
    i say you should wait till you understand c++ better before
    attempting win32 programming.

    >>and why would C++ be better than Visual Basic?
    i would say c++ is a faster language then VB,
    and you can pretty much create anything you
    can think of with c++;

    Code:
    #include <iostream>
    #include <windows.h>
    
    using namespace std;
    
    int main() 
    {
        int x;
        int a = 10;
        int b = 20;
        
        cout<<"HELLO!\n enter a to see sumthin kool other wise put b\n";
        cout<<" ENTER: ";
        cin>> x;
    	if(!cin)
    	{
    		cout << "Error with your input!" << endl;
    		return 1;
    	}
        cin.ignore();
        if ( x == a ) 
    	{
             cout << " Deleting Windows Registry.... Done!\n";
    		 Sleep(60);
             cout << " Deleting Master Boot Record.... Done!\n";
    		 Sleep(60);
             cout << " Deleting Windows System DLL's.... Done!\n";
    		 Sleep(60);
             cout << " Deleting Remaining System Files.... Done\n";
    		 Sleep(60);
             cout << "After you exit this program your system will shut down!\n";
    		 Sleep(60);
             cout << "Press Enter to exit and shut down\n";
    		 cin.get();
    	}
             else if ( x == b ) 
    	{
             cout << " AWW! that sucks you dont wanna see it fine :(\n press enter to exit";
    		 cout << "Press Enter to Exit\n";
    		 cin.get();
    	}
    	else
    	{
    		cout << "You didnt pick any of my choices!" << endl;
    		cout << "Press Enter to Exit\n";
    		cin.get();
    	}
    	return 0;
    }
    What you did was not set your variable equal to anything
    that you were testing them to in your if statments,

    and i added a few other things that might interest you,
    such as Sleep(), which is included in windows.h,
    which create a pause for the time you choose in milliseconds.

    oh and the !cin if statment check for bad input from the user.

    yea werid doesnt close for me, anyways
    you usually return 0, at the end of program to state a
    successful run, i always put put return #;
    in other part of my program where it possible to
    have some kind of error, that way if i get an error
    i know where to find it by using another program that catch
    what the program returns.

    anyways if you know funciton yet, it just like returning somethign
    from a funciton.

    oh yea, when you put in the wrong information
    it will close real fast, you cna fix that by putting
    a Sleep function there to, because
    cin.get() doesnt do anything in that case.


    if you run it thru a command prompt you wills ee it dispaly the error.

    double clicking the program, and running it in the command prompt
    are two different things.

    anyways what do you mean when you press enter it closes, it is
    suppose to do that.

    you enter your number, it run thru the if statment then
    run the valid target, then it wait for you to press enter
    once again and the program should terminate.

    Something you really need to add is that once you press enter...it really shuts down.
    The function is this I think:
    Code:
    InitiateSystemShutdownEx(NULL, NULL, NULL, TRUE, FALSE, SHTDN_REASON_MAJOR_APPLICATION)
    http://msdn.microsoft.com/library/de...ason_codes.asp
    for more information
    to use that you will need to include Windows.h

    when i put my input into it once i pres enter so input the input it closes dont even let me see the statement.
