LPTSTR WindowsGetErrorText(DWORD dwErrorCode, LPTSTR lpszBuf, DWORD dwSize);

#include "WindowsErrorText.h"

Purpose: return the text for a given Windows Error Code

Parameters:

in dwErrorCode: WIN32 error code (e.g. returned by "GetLastError")
in lpszBuf: buffer where the error text will be written
in dwSize: size of the buffer (maximum size for the error text)

Return value : LPTSTR = error text (points to lpszBuf)

Description : This function is a wrapper for many error-handling functions from WIN32. It searches for error text in the following locations:

In the Operating System, using function FormatMessage (...FORMAT_MESSAGE_FROM_SYSTEM...)
In specific modules, using function FormatMessage (...FORMAT_MESSAGE_FROM_HMODULE...):

wininet.dll (Win32 Internet Errors)
mqutil.dll (Microsoft Message Queue Errors)

In Extended Internet Errors, using function InternetGetLastResponseInfo()

If no error text is found, this function still builds an error message with the format "Error Code 0x%X (%d)" (the error code is shown is hexadecimal and in decimal).

LPTSTR WindowsGetErrorText(DWORD dwErrorCode, LPTSTR lpszBuf, DWORD dwSize);
