Is there any examples about draw lines onto the current window?

I think a lot ,but cannot write it completely..

WinGetHandle("")

DllCall("gdi32.dll","int","MoveToEx"

DllCall("gdi32.dll","int","LineTo"

what's wrong with my code?

Global $gdi_dll = DllOpen ("gdi32.dll"), $user32_dll = DllOpen ("user32.dll")

$hwnd=WinGetHandle("C:")

DllCall ($user32_dll,"int","GetDC","hwnd", $hwnd)

$BlackPen =DllCall ($gdi_dll, "hwnd", "CreatePen", "int", "0", "int", "3", "hwnd", "0x00000000"); large black pen

DllCall ($gdi_dll, "hwnd", "SelectObject", "hwnd", $hwnd, "hwnd", $BlackPen)

DllCall ($gdi_dll, "int", "MoveToEx", "hwnd", ($hwnd), "int", "0", "int", "0", "ptr", 0)

DllCall ($gdi_dll, "int", "LineTo", "hwnd",($hwnd), "int", "500", "int", "500")
