Windows Hresult Error Codes, Use of these codes requires some amount of investigation and analysis.

Windows Hresult Error Codes, Most values also have a default message defined, which can be used to map the value to a human-readable text message; when this is done, the HRESULT value is also known as a message identifier. Is there a function in win API which can be used to extract the string representation of HRESULT value? The problem is that not all return values are documented in MSDN, for example Use ERR. Microsoft documents that HRESULT uses a severity bit, a facility field, and a code field, Microsoft Visual Basic substantially enhanced the HRESULT error reporting mechanisms, by associating an IErrorInfo object with an HRESULT and storing (a pointer to) an IErrorInfo object in thread-local That is where ERR. For every method or function that returns an HRESULT, check the return value before proceeding. I hope this information will help you troubleshoot Device Error Codes The InvokeAction and QueryStateVariable methods return HRESULT values that might indicate a device error (that is, an error that is received from a UPnP-certified device). Here are some of the possible encodings: All Win32 error codes MUST be in the range 0x0000 to 0xFFFF, although Win32 error codes can be used both in 16-bit fields (such as within the HRESULT type specified in section 2. OpenGL Vulkan Windows (HRESULT, Win32, NTSTATUS, and Windows Installer codes) HTTP Linux kernel (errno. You need to note both the programmatic and the run-time context in which these errors occur. The error handling macros are described in the following table.
