SetWindowDisplayAffinity does not work for console app

Question

I get accessdenied(5) error in following console app codes, is there anyway to protect console window against screenshot?

int wmain(void)
{
    HWND hWnd = GetConsoleWindow();
    BOOL b = SetWindowDisplayAffinity(hWnd, WDA_MONITOR);
    DWORD e = GetLastError();   // e==5
    return 0;
}

Answer 1

According to the documentation:

Parameters

hWnd

Type: HWND

A handle to the top-level window. The window must belong to the current process.

The console does not belong to the current process, so the HWND cannot be set.
