RE: [GD-Windows] Finding HWND of the current thread

[Jon W. <hp...@mi...>]

May I suggest that you're not guaranteed that GetModuleHandle() returns a
pointer to your executable header, and you're not guaranteed that your
executable loads at 0x400000 ? They might have a hard time changing this
behavior for existing apps, especially because of hacky code like the posted
code, but you never know about future versions.

If you want the header, use GetModuleFileName() on the main module, and read
the header yourself. Then check whether the header is actually a "PE"
header, and just assume you're not console if it isn't. At least, that won't
CRASH when you port your code, or some new version of Windows comes out.

Cheers,

You can check the Subsystem field of the PE "optional" header (always
present): if it's equal IMAGE_SUBSYSTEM_WINDOWS_CUI (3), you've got a
console app.
void* base = (void*)0x400000 (or GetModuleHandle(0))
IMAGE_NT_HEADERS* h = ImageNtHeader(base)
h->OptionalHeader.Subsystem == 3?

Disclaimer: off the top of my head and ugly to boot ;)
