How to Get and Set the System Resolution using C#

I found the solution for getting the screen resolution, But how to set in Runtime?



var d = Sys["Desktop"];

ShowMessage(d["Height"]);

ShowMessage(d["Width"]);

{

var dm, dwLastError;

res = -1;

dm = Win32API["DEVMODE"]();

if(Win32API["EnumDisplaySettings"](VarToInteger(0), -1, dm) != 0)

{

dm["dmPelsWidth"] = x;

dm["dmPelsHeight"] = y;

dm["dmBitsPerPel"] = d;

res = Win32API["ChangeDisplaySettings"](dm, 0);

}

else

{

dwLastError = Win32API["GetLastError"]();

Log["Error"]("Error code: " + VarToStr(dwLastError));

}

return res

}

{ 

//Delay(2000);

SetDisplay(1280, 1024, 64);

Log["Message"]("New resolution: " + VarToStr(Sys["Desktop"]["Width"]) +

"x"+VarToStr(Sys["Desktop"]["Height"]));

}
