If a method throws an exception in managed code, the common language runtime can pass an HRESULT to a COM object. If a method fails in unmanaged code by returning a failure HRESULT, the runtime throws an exception that can be caught by managed code.The runtime automatically maps the HRESULT from COM interop to more specific exceptions. For example, E_ACCESSDENIED becomes UnauthorizedAccessException, E_OUTOFMEMORY becomes OutOfMemoryException, and so on.If the HRESULT is a custom result or if it is unknown to the runtime, the runtime passes a generic COMException to the client. The ErrorCode property of the COMException contains the HRESULT value.Working with IErrorInfoWhen an error is passed from COM to managed code, the runtime populates the exception object with error information. COM objects that support IErr

Join them; it only takes a minute: Sign up Symbolic error code Names for COMException HRESULT Error Codes in .NET up vote 3 down vote favorite I would like to be able to use the standard symbolic names for HRESULTs returned by COM components in my .NET code. For example, I'd like to be able to write code like this: try { someComObject->DoSomething(); } catch (COMException ex) { if (ex.ErrorCode == E_FAIL) { HandleFail(); } comexception error codes else if (ex.ErrorCode == E_OUTOFMEMORY) { HandleOutOfMemory(); } else { HandleComError(ex.ErrorCode); } } However, I can't find anyplace in the .NET frameworks where symbols like E_FAIL, E_OUTOFMEMORY, E_UNEXPECTED, and so on are defined. For native Win32 apps, one can get the definitions from
