You rely on zero-extension, right?

[Mikl__]

Buona sera, signore jj2007!
The program doesn't play the wmv-file again?

[jj2007]

Добрый вечер, Майкл!

It plays, sure. I just wonder if your uses of 32-bit registers for pointers are safe. Is the stack guaranteed to be in 32-bit land?

        lea eax,lpcbData

mov [rsp+20h],rdi

[Mikl__]

The use of 32-bit registers with their zero extension in 64-bit and 32-bit addresses with /LARGEADDRESSAWARE:NO is just a way to make the tiny size program I create my exe-/dll-/sys-files using bat-file

Do You live in Italy and try not to use Italian?

[jj2007]

OK, so you need the linker option. The result will be a bit like x32 ABI

Do You live in Italy and try not to use Italian?

Yes, I live here, and use 4 languages every day, including Italian, of course 8)

[Mikl__]

In my programs there is no need to use 48- or 64-bit addressing.
I taught myself Italian. Then there were no Google-translators. I just do not have enough practice.

[jj2007]

C'è un solo modo valido per imparare l'italiano: praticarlo con una bella italiana

[Mikl__]

imparare qualsiasi lingua è utile con una bella interprete sul cuscino

one is jj2007 he has workig program, I'm interested - 63 men have workig program or they have unworking program?

It looks like some robot trains in downloading a file. Yesterday there were 64 downloads, today 128 and no comments about the program
