asynchronous object loading DirectX gives you the possibility to create objects e.g. Transcript The interactive transcript could not be loaded. This reduces the amount of member functions since XXSetShaderResources exists for multiple shader types. Because the flow of control continues through the function after a failure, you must be careful throughout the body of the function not to access invalid resources.

but isn't yet perfect so I'm getting the "out of memory" stuff. –DAG Sep 11 '15 at 17:06 It can be a bit flaky, yes, and it's unfortunate there And exceptions are not allowed to cross COM boundary. Should I investigate more on the Lenovo or could I accept a rendering procedure whose some DirectX calls are failing ..

Advantages This pattern creates less nesting than the "nested ifs" pattern. Browse other questions tagged c++ exception-handling directx or ask your own question. This allows you to load objects while the game is rendering other stuff (splash screen or loading animation).

I bet that switchable graphics can cause lost devices without the user even needing to go near either the Alt key or the Tab key.) It appears that the gentleman thought Is there ferry service from Vietnam to Borneo? This documentation is archived and is not being maintained. _com_error Description Wendy Jones devoted herself to computers the first time her eyes befell an Apple IIe in elementary school.

Note   Calling MAKE_HRESULT for S_OK verification carries a performance penalty. _com_error Example If you wish to continue this conversation start a new topic. Inside a loop, break from the loop if any call fails. The following table shows some of those system-wide return codes.

S_ok Value Anyway, DirectX is not the API to start to learn exception safety.

Error checking Since the COM functionality is encapsulated in these classes, it is possible to automaticly check for errors (for instance HRESULT return type of COM functions). C++ Hresult To String Advantages Compatible with existing code that uses exception handling. Investigating a little bit and debugging the code, I noticed some of the directX calls (most of them during the rendering phase) where not returning D3D_OK (whereas texture are loaded correctly

It can also indicate a "no-op"—the method succeeded, but had no effect.

You can then throw an exception in your own code if that makes sense for your project.

S_FALSE0x1Success.   All of the constants with the prefix "E_" are error codes.

Copy // Wrong. Instead, they use C-style return codes, which are called HRESULT, to indicate errors. 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. Similarly it's not that easy to make the device crash and have to reset.

If you work on an existing project, it might already have coding guidelines that proscribe a particular style. Why didn't Doctor Strange use the Eye of Agamotto to heal his hands? pros of my approach: (almost, there are exceptions) no COM objects visible automatic management of COM objects easy access through keys (proprietary use of objects) multiple function calls forming a specific Register now!

I am still investigating where do the error exactly come from. I would guess the latest Intel driver installer is attempting to bypass ugly "device removed" errors... TL;DR - I'm having trouble wrapping my head around how I should approach building a rendering engine architecture that will accept all the different types of objects I want to render, You can do this by dispatching a compute shader containing an infinite loop, such as the following: cs.hlsl RWBuffer dummyUAV; cbuffer dummyCB {uint zero;} [numthreads(256, 1, 1)] void main(uint3 id :

I want to come up with a method of controlling how my COM objects are constructed and destructed, to protect my program from wanton destruction of these objects.
