Thank you very much! But I have this error when I try to compile:

Error 42: Symbol Undefined _InitCommonControls@0
Error: linker exited with status 1

I am using Resedit.exe for create dialog resource and compiled .rc to .res for link.

probably, you need to link your exec with comctl32.lib

Very good!! Working fine adding:
pragma(lib, "comctl32.lib");
