Lock Computer

[clover]

I want to keep my screen running, but lock my computer while I'm away using this program:

I looked in the MSDN website: http://msdn2.microsoft.com/en-us/library/ms646290.aspx

It's not compiling :(

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

int main()

{
   

BOOL BlockInput

{  
         
    BOOL fBlockIt
    
);

cout << BlockInput;

return 0;

}

you need include #include <windows.h> also;)

#include <windows.h>                                
#include <winable.h>
int main()
{
BlockInput(TRUE);
   Sleep(1000);
BlockInput(FALSE);
Sleep(1000);
return 0;
}
