L“先修复调用CDXUTDialog :: Init（），请参阅注释了解详细信息。”

Question

调用回调函数DXUTCreateDevice（）错误正在从DXUTgui.cpp断言检查返回。断言说，首先调用CDXUTDialog :: Init（），但我应该把它放在WinMain（）？

Answer 1

比较您DXUT客户端代码的EmptyProject和SimpleSample内容--assuming您正在使用的DXUT11从GitHub。

的典型模式是创建一个全局变量CDXUTDialogResourceManager，然后调用CDXUTDialog::Init从InitApp你DXUTCreateDevice

int WINAPI wWinMain(_In_ HINSTANCE hInstance, _In_opt_ HINSTANCE hPrevInstance, _In_ LPWSTR lpCmdLine, _In_ int nCmdShow) 
{ 
    // Enable run-time memory check for debug builds. 
#ifdef _DEBUG 
    _CrtSetDbgFlag(_CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF); 
#endif 


    // DXUT will create and use the best device 
    // that is available on the system depending on which D3D callbacks are set below 


    // Set DXUT callbacks 
    DXUTSetCallbackMsgProc(MsgProc); 
    DXUTSetCallbackKeyboard(OnKeyboard); 
    DXUTSetCallbackFrameMove(OnFrameMove); 
    DXUTSetCallbackDeviceChanging(ModifyDeviceSettings); 


    DXUTSetCallbackD3D11DeviceAcceptable(IsD3D11DeviceAcceptable); 
    DXUTSetCallbackD3D11DeviceCreated(OnD3D11CreateDevice); 
    DXUTSetCallbackD3D11SwapChainResized(OnD3D11ResizedSwapChain); 
    DXUTSetCallbackD3D11SwapChainReleasing(OnD3D11ReleasingSwapChain); 
    DXUTSetCallbackD3D11DeviceDestroyed(OnD3D11DestroyDevice); 
    DXUTSetCallbackD3D11FrameRender(OnD3D11FrameRender); 

    InitApp(); <-- // THIS IS WHERE DXUT GUI WIDGETS GET INITIALIZED, BEFORE THE WINDOW OR DEVICE IS CREATED 
    DXUTInit(true, true, nullptr); // Parse the command line, show msgboxes on error, no extra command line params 
    DXUTSetCursorSettings(true, true); 
    DXUTCreateWindow(L"SimpleSample11"); 


    // Only require 10-level hardware, change to D3D_FEATURE_LEVEL_11_0 to require 11-class hardware 
    // Switch to D3D_FEATURE_LEVEL_9_x for 10level9 hardware 
    DXUTCreateDevice(D3D_FEATURE_LEVEL_10_0, true, 800, 600); 


    DXUTMainLoop(); // Enter into the DXUT render loop 


    return DXUTGetExitCode(); 
} 

得到一个回调之前开始使用DXUT一个新的项目，不推荐。它仅用于维护对DXUT具有依赖性的现有代码，同时消除对D3DX11和其他旧版DirectX SDK内容的依赖性。绝大多数DXUT的功能对于大多数应用程序来说都是完全过度的。这也是越野车，并且仅用于样本。
