Hello to everyone!!

I used Direct3D9 for 1 year and learned a lot of things (shaders, skinned meshes...), ok.
In particoular, i used debug dll and SDK installed automatically Visual Studio Extension that allowed D3D debug Directly from Visual Studio (in the output window there were a lot of D3D messages like Infos, but also debug, like wrong procedures, memory leaks) and it was very useful.

In D3D10 i'm not able to find the same feature.
I've enabled in D3D10 tab of DirectX Control Panel the Debug selecting my projects folder (./VisualStudio 9/Projects) and now if there are some problems it lanchs an exception and in output windows i can find the error...but not every time.
For example
   
    //In upper part of my cpp file
    #define CHECK_HR(t) if (t != S_OK) {MessageBox(NULL,"Error",NULL,MB_OK);}

    //After device creation...
    hr = scritta->DrawText(NULL,"Ceccio!",-1,&rect,DT_LEFT,D3DXCOLOR(3,0,2,2));
    CHECK_HR(hr);

If i try to run the code, it gives me the error messagebox, but in output windows there is nothing that can help me!
Is there a way to analize any kind of Direct3D10 message?
Here is complete source code if it can help you.

You need to add the D3D10_CREATE_DEVICE_DEBUG flag to your creation call. But you need to be careful. If you release an application with this flag it will only run on systems where the SDK is installed.

I've add the flag in D3D10CreateDeviceAndSwapChain but nothing changed.
From the guide, i've found that i've to create a ID3D10InfoQueue interface by making a QueryInterface from the device...and then? How can i read messages?

There is not way to show messages in output window of Visual Studio?
Thank you again!

If you enable the debug layer you should be able to see the messages in the output window of the debugger. You should check if you don’t have force the debug layer to off for your application in the control panel.

I've found the error: DrawText() function does not give an HRESULT, but an int!
So if int = 0 then the function failed. I checked like an HRESULT and so there where every time error!

Anyway, the D3D10 debug it's very different than D3D9 one. The new debug layer does not say me infos about Device, SwapChain, does not say me anything about memory leaks...

Sob.

I ask your help again, please.
The Direct3D debug output does not say me nothing about this code, but i can't see the words on the screen!
Thank you!!

I am having similiar problems. I use the  March 2008 SDK on a NVIDIA GT 8800. I havent been able to get any debug messages out in the Visual Studio output console.

The DirectX10 Control Panel under Vista seems to be disabled.

Anyone had any luck with the new debug layer?

 

 

 

 

 

 

Make sure you link with the debug library:

d3dx10d.lib
