See here for details. I do think there is scope for someone to write a book which covers all aspects of using Window API from a FORTRAN environment. Something that is also worth discussing is that: in the Jadhav's article, some message board posters claimed that _com_error::_com_error() needs a HRESULT always, hence you have to pass the output of This flag cannot be used with FORMAT_MESSAGE_FROM_STRING. http://stackoverflow.com/questions/1387064/how-to-get-the-error-message-from-the-error-code-returned-by-getlasterror

dwLanguageId = MAKELANGID(LANG_NEUTRAL,SUBLANG_NEUTRAL), & dwLanguageId = MAKELANGID(LANG_NEUTRAL,SUBLANG_DEFAULT), & lpBuffer = C_LOC(lpBuffer), & nSize = 255_DWORD, & Arguments = C_NULL_PTR) write(*,'(a,i0)') 'Return value from CopyFile = ', bstatus write(*,'(a,i0)') 'Return value from lpSource = transfer(C_NULL_PTR, lpSource) ! By definition every negative HRESULT is an error. Thank you!

  1. What does "M.C." in "M.C.
  2. This should be called at the very * beginning of your program. * */ void win32_InitException( void ) { _set_se_translator( win32_Exception ); }/**************************************************************************//*! * Handles exceptions.
  3. I will have to compare this to a working example I have to see if I can see what might be wrong.
  4. I was not aware that you could also use them for dealing with Win32 calls and that is very helpful and useful.

To convert a system error into an HRESULT value, use the HRESULT_FROM_WIN32 macro. There are other possible return values (S_FALSE for example), that are sometimes used to indicate special situations but are not considered an error. Not if the class doesn't depend on such, and thankfully, _com_error doesn't. Getlasterror C# Hang on.

FORMAT_MESSAGE_IGNORE_INSERTS 0x00000200 Insert sequences in the message definition are to be ignored and passed through to the output buffer unchanged. Getlasterror Formatmessage We looked at how to use a 'built-in' class, the _com_error class, which is provided along with the VC++ compiler, to generate human-readable errors from COM and Win32 calls. I had FORMAT_MESSAGE_ALLOCATE_BUFFER in dwFlags which may be what caused a problem otherwise they are essentially the same. Here are the steps.

The type of this parameter depends upon the settings in the dwFlags parameter. Str_elems HaeRim Sign In·ViewThread·Permalink Can we use this with WSAGetLastError () for reporting WinSock errors? Needless to say, there's a class, called _com_error, which you can use in lieu of some other ungodly approach, say, by using FormatMessage(). PInvokin' Tom Out.

Getlasterror Formatmessage

You could also do the same thing with PInvoke by calling the FormatMessage function, but I am lazy and keep as much in C# as I can. Discussion It's worth discussing this particular approach to error-handling, and in particular cases in which it's not a good idea. Getlasterror Codes If the module has no message table resource, the function fails with ERROR_RESOURCE_TYPE_NOT_FOUND.

If the length of the formatted message exceeds 128K bytes, then FormatMessage will fail and a subsequent call to GetLastError will return ERROR_MORE_DATA. check my blog Remarks Functions executed by the calling thread set this value by calling the SetLastError function. This documentation is archived and is not being maintained. Posted in PROGRAMMING Technical Information Database TI2459C.txt Displaying an error string from GetLastError. Formatmessagew

Or the caller can ask the function to search the system's message table resource(s) for the message definition. Sign In·ViewThread·Permalink Re: Nice article.

Steve - Intel Developer Support Top dannycat Tue, 12/18/2012 - 05:34 Thanks to both of you guys for the info, it has been very helpful. Getlasterror 126 Since FormatMessage already returns the length we could dispense with all procedure calls in your sample by changing the declaration of message_buffer to character(:), pointer :: message_buffer and then we could The function ignores regular line breaks in the message definition text.

If you replaced %5 with %1, the function would try to print a string at address 6 (likely resulting in an access violation).

If you're not coding an MFC application, then add the line below to whatever file is #included in all your source files. In particular, it is unsafe to take an arbitrary system error code returned from an API and use FORMAT_MESSAGE_FROM_SYSTEM without FORMAT_MESSAGE_IGNORE_INSERTS. Sign In·ViewThread·Permalink Re: Thank You! C# Getlasterror Message Or the caller can ask the function to search the system's message table resource(s) for the message definition.

dwLanguageId TRANSFER(C_LOC(message_buffer_cptr), 0_LPVOID), & ! Plus, the _com_error class is itself an exception class, and works with the compiler's built-in exception handling syntax. Sign In·ViewThread·Permalink Problem janoslo17-Jun-09 4:19 janoslo17-Jun-09 4:19 I traditionally used FormatMessage and knew it was pretty insufficient. http://itechnologysolutionsllc.com/error-code/win32-error-code-1460.php Listing 4 shows how I set up the bogus Win32 call:void CSimpleErrorsDlg::OnBnClickedCallFunction() { // Do something bogus here, like try to open a file // which doesn't exist.

nSize [in] If the FORMAT_MESSAGE_ALLOCATE_BUFFER flag is not set, this parameter specifies the size of the output buffer, in TCHARs. Format stringResulting output %%A single percent sign. %spaceA single space. It's clear from the message board posts in Jadhav's article that people are aware of this, but it is in fact quite simple to use, and it works in a proven However...

What does no_errorlog variable do (there is no check on optional variable - should it be API_error_report and why is function defined as recursive? Some C++ class contructors (like _bstr_t) will make WIN32 API calls to allocate resources, and if the arguments to the error formatting function use these objects, GetLastError() may actually return 0 Unfortunately, exception handling is not really my bag, so this article looks at only how to use the _com_error::ErrorMessage() member function. This buffer cannot be larger than 64K bytes.
