The problem is that not all return values are documented in MSDN, for example ExecuteInDefaultAppDomain() function is not documented to return "0x80070002 - The system cannot find the file specified.", however, it does! Therefore, I was wondering whether there is a function to be used in common case. c++ windows winapi clr hresult share|improve this question asked Aug http://stackoverflow.com/questions/7008047/is-there-a-way-to-get-the-string-representation-of-hresult-value-using-win-api 10 '11 at 8:44 khkarens 4411414 2 Title is different, but essentially the answer will be the same as for this one. –Christian.K Aug 10 '11 at 8:49 add a comment| 3 Answers 3 active oldest votes up vote 43 down vote accepted You can use _com_error: _com_error err(hr); LPCTSTR errMsg = err.ErrorMessage(); If you don't want to use _com_error for whatever reason, you can still take a look at its source, and see how it's done. share|improve this answer edited Jul 24 at 19:43 Cory Nelson 17.1k23061 answered Aug 10 '11 at 8:50 eran 14.8k3371 thank you eran! –khkarens Aug 10 '11 at 8:58 2 A more complete sample for convenience: inline CString GetMessageForHresult(HRESULT hr) { _com_error error(hr); CString cs; cs.Format(_T("Error 0x%08x: %s"), hr, error.ErrorMessage()); return cs; } –nietras Feb 9 '12 at 15:55 add a comment| up vote 11 down vote The Windows API for this is FormatMessage. Here is a link that explains how to do it: How to obtain error message descriptions using the FormatMessage API. For Win32 messages (messages with an HRESULT that begins with 0x8007, which is FACILITY_WIN32), you need to remove the hi order word. For example in the 0x80070002, you need to call FormatMessage with 0x0002. However, it does not always work for any type of message. And for some specific messag

Use compiler COM support (even in non-COM applications) to get a Win32 error code or HRESULT's message in one line of code. Download source files - 2.72 KB Download demo project - 20.7 KB Figure 1. The SimpleErrors sample application for this article. Introduction In your previous project, you may have called Win32 or COM functions. This article won't discuss the particulars of calling such functions, but instead my purpose is to reveal a really simple way to handle errors from these functions. Mostly the functions themselves only return a hard-to-parse HRESULT (from COM) or an invalid HANDLE value (such as INVALID_HANDLE_VALUE or some other such value). But it's not easy to get the error that actually occurred, so that one can just display the message to the user. Other articles on the Code Project, such
