How to obtain the information output by the ReportLiveDeviceObjects interface in memory?

Currently, it can only be seen in the output of the debugger. I hope to obtain it in the app's memory for easy user interaction

Did you determine if it uses the OutputDebugString function? For example, use the DebugView tool (from Microsoft) and start your program without Visual Studio. Maybe you can intercept the messages in the same manner.

I attempted to intercept the OutDebugString interface, but unfortunately there was no output of relevant information. At the same time, using DebugView can observe relevant outputs, and it is unclear how DebugView information is obtained

Hello,

Welcome to Microsoft Q&A!

I suggest you could try to enable the debug layer.

To enable the debug layer, specify the D3D11_CREATE_DEVICE_DEBUG flag in the Flags parameter when you call the D3D11CreateDevice function to create the rendering device.

And then you could try to call ID3D11Debug::ReportLiveDeviceObjects method with D3D11_RLDO_DETAIL to obtain detailed information about a device object's lifetime.

Thank you.

Jeanine

Yes, that's what I did, but my current problem is that the information generated by ReportLiveDeviceObjects can only be viewed in the debugger output or DebugView, and what I want is to be directly obtained in memory. For example, I want to save it as a string and do some other business based on this string

You could try to hook OutputDebugStringW via Detours library. And here is a sample you could refer to: https://stackoverflow.com/a/24322128/11872808

I did indeed do this, but unfortunately, I was able to obtain other information through Hook OutputDebugStringA and OutputDebugStringW, but only the information generated by the ReportLiveDeviceObjects interface could not be obtained.

If the information generated by ReportLiveDeviceObjects can only be viewed in the DebugView. You could use the Capture | Capture Global Win32 menu item to see log messages. From the File menu, select Log To File to save the Debug Log output as a text file.

If you are using it from C#? If so, I suggest you should try to use mixed-mode debugging. You should check "Enable native code debugging" in your project settings.
