所以我在为C++图形应用程序窗口设置默认图标时遇到了问题。我正在学习DirectX 11系列教程（找到here）任务栏图标更改得非常好，生成的可执行文件使用自定义图标，但由于某种原因，应用程序窗口没有。根据Microsoft文档中找到的here，我应该在WNDCLASSEX中设置两个HICON属性的值：hIcon和hIconSm;根据研究，其可以设置为LoadIcon(hInstance, IDI_APPLICATION)，如本例中所示LoadIcon我不完全确定会采取什么步骤来重现这个问题。我不知道当我在.ico映像中加载.rc文件时是否出了问题。或者我加载的映像不正确，或者...嗯...一些模糊的原因导致它只能工作一半。这是我注册用来创建窗口的窗口类的代码 // The window class. This has to be filled BEFORE the window can be WNDCLASSEX wc;
/ Flags [Redraw on width/height change from resize/movement]
wc.style = CS_HREDRAW | CS_VREDRAW | CS_OWNDC;
// Pointer to the window processing function for handling messages from this window
wc.lpfnWndProc = HandleMessageSetup;
// Number of extra bytes to allocate following the window-class structure
wc.cbClsExtra = 0;
// Number of extra bytes to allocate following the window instance
wc.cbWndExtra = 0;
// Handle to the instance that contains the window procedure
wc.hInstance = m_hInstance;
// Handle to the class icon. Must be a handle to an Icon resource
wc.hIcon = LoadIcon(m_hInstance, IDI_APPLICATION);
// Handle to the small icon for the class
wc.hIconSm = LoadIcon(m_hInstance, IDI_APPLICATION);
// Handle to the class cursor. If null, an application must explicitly set the cursor shape whenever the mouse moves into the application window
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
// Handle to the class background brush for the window's background colour. When NULL an application must paint its own background colour
wc.hbrBackground = NULL;
// Pointer to a null-terminated string for the menu
wc.lpszMenuName = NULL;
// Pointer to null-terminated string of our class name
wc.lpszClassName = m_windowClass.c_str();
wc.cbSize = sizeof(WNDCLASSEX);
// Register the class to make it usable
RegisterClassEx(&wc);如果需要更多代码，可以在github上找到我的存储库（主要类是engine/RenderWindow）根据研究，使用CreateWindowEx创建窗口应该很简单。我的任务栏图标会改变，但应用程序窗口图标不会改变。Screenshot没有错误。代码编译并运行成功。
