CVersionInfo is a tiny class, which wraps the stuff needed to get the version info from a resource file. It handles both, the fixed version information and the language dependent string version information of the resource file. It contains three CString members which hold the retrieved information:
m_strFixedFileVersion: the fixed file version info (language independent)
m_strFixedProductVersion: the fixed product version info (language independent)
m_strVersionInfo: the desired version info string (language dependent)
To get the language dependent string version info you need to set the following parameters as follows:
strLangID:
strLangID is the language ID for which the version info is desired
040904E4 means e.g.:
04—— = SUBLANG_ENGLISH_USA
–09—- = LANG_ENGLISH
—-04E4 = 1252 = Codepage for Windows:Multilingual
strInfoType:
strInfoType is the desired version entry, eg.:”ProductName”, or “ProductVersion”
hModule:
hModule ist the Instance handle of the module for which the version info should be retrieved
with EXE’s: Get hModule calling AfxGetInstanceHandle.
with DLL’s: Get hModule calling ::GetModuleHandle (“DLLName”), where “DLLName” is the Name of the module
Important!
CVersionInfo requires to be linked with VERSION.LIB!Here’s the code:
// VersionInfo.h
#ifndef VERSIONINFO_H
#define VERSIONINFO_H
#include “stdafx.h”
class CVersionInfo
{
public:
