where are the .dll for vertically tile windows command?

[JuJuBeed]

You know, you can right click on the taskbar and select "tile windows
vertically." I want to create a keyboard shortcut for this to make it
quicker. Where is the .dll for "vertically tile windows"? I found the ones
that allow me to do it horizontally, but what about vertically. Here is are
the two I found:

RunDll32.exe USER.DLL,tilechildwindows
RunDll32.exe USER.DLL,cascadechildwindows
