How to call PrepareDiscForBurnRunDll function with dllcall?

[kosamja]

PrepareDiscForBurnRunDll opens this dialog

this works from bat file

"C:\Windows\system32\rundll32.exe" C:\Windows\system32\shell32.dll,PrepareDiscForBurnRunDll H:\

but this dllcall doesnt work

DllCall('shell32.dll', 'none', 'PrepareDiscForBurnRunDll', 'str', 'H:\')

How to write dllcall so that this dialog opens?

Probably like this:

DllCall("shell32.dll", "none", "PrepareDiscForBurnRunDllW", "hwnd", Null, "handle", Null, "wstr", "H:\", "int", 1)
