How to convert a message (ex:13928) to an Message ID (ex: ERROR_IPSEC_DOSP_STATE_LOOKUP_FAILED) How to do that?

When retrieving an error code using GetLastError():

GetLastError()

It retrives an code, not a message ID or message

How do I convert an error code to a message ID and without loops?

    Since winerror.h uses the preprocessor #define to associate a "message id" with the numeric value you would need to create your own lookup table. There is no Windows API function to convert the actual error code to the "message id" that is seen by the preprocessor.

    With FormatMessage

    But it depends on the resource DLL

    13928 gives "La protection DoS IPsec n’a pas pu rechercher l’état.\r\n" on my french OS

    FormatMessage is the way to get the message from a system code
