How to enable visual styles without a manifest

Solution 1:

There's actually a third way with no manifests whatsoever, though it's rather hacky:

#include <windows.h>

// NOTE: It is recommended that you delay-load ComCtl32.dll (/DelayLoad:ComCtl32.dll)
// and that you ensure this code runs before GUI components are loaded.
// Otherwise, you may get weird issues, like black backgrounds in icons in image lists.
ULONG_PTR EnableVisualStyles(VOID)
{
    TCHAR dir[MAX_PATH];
    ULONG_PTR ulpActivationCookie = FALSE;
    ACTCTX actCtx =
    {
        sizeof(actCtx),
        ACTCTX_FLAG_RESOURCE_NAME_VALID
            | ACTCTX_FLAG_SET_PROCESS_DEFAULT
            | ACTCTX_FLAG_ASSEMBLY_DIRECTORY_VALID,
        TEXT("shell32.dll"), 0, 0, dir, (LPCTSTR)124
    };
    UINT cch = GetSystemDirectory(dir, sizeof(dir) / sizeof(*dir));
    if (cch >= sizeof(dir) / sizeof(*dir)) { return FALSE; /*shouldn't happen*/ }
    dir[cch] = TEXT('\0');
    ActivateActCtx(CreateActCtx(&actCtx), &ulpActivationCookie);
    return ulpActivationCookie;
}

Solution 2:

If you're using Visual Studio, you can add this line to your stdafx.cpp for example:

#pragma comment(linker,"\"/manifestdependency:type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")

Solution 3:

If you had kept reading, you would have found the answer:

If you are using Microsoft Visual C++ 2005 or later, you can add the following compiler directive to your source code instead of manually creating a manifest. For readability, the directive is broken into two lines here.

#pragma comment(linker,"\"/manifestdependency:type='win32' name='Microsoft.Windows.Common-Controls' 
version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")
