ShowWindow(FindWindow
 

For the 2 parameters lpClassName and lpWindowName in FindWindow, what do i throw in there to hide all open windows? Is this possible? MSDN makes it sound like if both parameters are null, that will do the trick, but before i test it, i want to make sure that works so i dont have to restart my computer before i reverse the action

FindWindow will only return a handle to one window, to do this you will have to loop through all opened applications and hide them one at a time. Try looking up the EnumWindows function, it may provide your solution.

I looked that function up, but im still confused, could you elaborate on a proper method to hide all open windows? Im still a new programmer/windows programmer.

#include <windows.h>

#include <iostream>

#include <vector>



using namespace std;



std::vector<HWND> vis;



bool EnumWindowsProc(HWND hWnd, long lParam)

{



    if (IsWindowVisible(hWnd)) {

        vis.push_back(hWnd);

    }



    return true;

}





int main()

{

    EnumWindows((WNDENUMPROC)EnumWindowsProc, 0);



    for (int i=0; i < (int)vis.size(); i++) {

        ShowWindow(vis[i], SW_HIDE);

    }



    Sleep(10000);



    for (int i=0; i < (int)vis.size(); i++) {

        ShowWindow(vis[i], SW_SHOW);

    }





    return 0;

}

Just remember to add code which prevents you from hiding the console window (ie: the one that they need in order to type in their password). This program as it is now, simply hides all windows for a short amount of time, and then makes them show up again.
