Downgrading drivers should work as well, so you can just toggle between two driver versions while your code is executing to make sure you react correctly. Then, put the next method call within the scope of the if statement. example: hr = this -> device -> CreateSamplerState(samplerDescriptions[i], &samplerState); if(!SUCCEEDED(hr)) { // error handler here } This code is contained inside a method called GraphicsEngine::AddSamplerStates. HRESULT hr = SomeFunction(); if (FAILED(hr)) { printf("Error!\n"); } The success code S_FALSE deserves mention. http://winhq.net/directx-error/directx-error-directx-function-createpixelshader.html

Otherwise, your program might leak resources. Topics include networked games, 3D multimedia applications, enable Force Feedback joystick devices in their own applications, multimedia applications that allow for multiple user input devices, and multimedia applications that use music To effectively work with DirectX, obviously you should learn at least some basics of COM. _com_error Description Using COM in Your Windows Program Error Handling in COM Error Handling in COM Error Handling in COM What Is a COM Interface?
