ActivateActCtx 启用的视觉样式不影响选项卡控件

Question

我确实使用以下代码启用了视觉样式：

void EnableVisualStyles2(void)
{
    TCHAR dir[MAX_PATH] = {0};
    GetSystemDirectory(dir, sizeof(dir) / sizeof(*dir));

    ACTCTX actCtx = {0};
    actCtx.cbSize = sizeof(ACTCTX);
    actCtx.dwFlags =  ACTCTX_FLAG_RESOURCE_NAME_VALID |
                      ACTCTX_FLAG_SET_PROCESS_DEFAULT |
                      ACTCTX_FLAG_ASSEMBLY_DIRECTORY_VALID;
    actCtx.lpSource = L"shell32.dll";
    actCtx.lpAssemblyDirectory = dir;
    actCtx.lpResourceName = (LPCTSTR) 124;
    ULONG_PTR cookie = FALSE;
    HANDLE h = CreateActCtx(&actCtx);
    assert(h != INVALID_HANDLE_VALUE);
    assert(ActivateActCtx(h, &cookie));
}

按钮很好，但 TabControl 和 ProgressBar 仍在使用旧样式：

这不是严格意义上的机器问题，我刚刚创建了一个常规清单，如下所示，选项卡控件 UI 没问题。

没问题：

我错过了什么？

Answer 1

根据 document:

你可以试试

icex.dwICC = ICC_TAB_CLASSES | ICC_PROGRESS_CLASS | ICC_STANDARD_CLASSES;

这样就可以继续调用InitComControls函数来保证table控件的加载

ActivateActCtx 启用的视觉样式不影响选项卡控件

visual style enabled by ActivateActCtx doesn't affect tab control
