Wine does not support detecting of wine, therefore whatever method is

Hence the detection method no longer works and the app now breaks.

Will Wine be abandoning its own set of registry keys?

Will detecting HKEY_CURRENT_USER\Software\Wine stop working at some
point in the future?

Probably not, but you cannot depend on it, as it's not supported. The
developers may choose to rename the registry keys at sometime in the
future.

Doubt. But what will prevent user from creating those keys on windows?

If you need a sure way to detect wine - look for any of internal Wine exports from ntdll with GetProcAddress().

Hi,

I have also been searching for a way to detect if my application is running under wine. As I haven´t found an appropriate solution I came to the following solution. It may not be perfect and there is no guarantee that it will always be working but I think it is a good approach.

Code: Select all

BOOL CMyClass::IsWine() 
{
	CString csRet;
	BOOL fRet = FALSE;
	CString csEntry = _T("ProductName");

	HMODULE hLib = LoadLibrary(_T("ntdll"));

	if (hLib != NULL)
	{
		HRSRC hVersion = FindResource( hLib, 
		MAKEINTRESOURCE(VS_VERSION_INFO), RT_VERSION );
		if (hVersion != NULL)
		{
			HGLOBAL hGlobal = LoadResource( hLib, hVersion ); 
			if ( hGlobal != NULL)  
			{  
				LPVOID versionInfo  = LockResource(hGlobal);  
				if (versionInfo != NULL)
				{
					DWORD vLen,langD;
					BOOL retVal;    

					LPVOID retbuf=NULL;

					TCHAR fileEntry[256];

					_stprintf(fileEntry,_T("\\VarFileInfo\\Translation"));
					retVal = VerQueryValue(versionInfo,fileEntry,&retbuf,(UINT *)&vLen);
					if (retVal && vLen==4) 
					{
						memcpy(&langD,retbuf,4);            
						_stprintf(fileEntry, _T("\\StringFileInfo\\%02X%02X%02X%02X\\%s"),
						(langD & 0xff00)>>8,langD & 0xff,(langD & 0xff000000)>>24, 
						(langD & 0xff0000)>>16, csEntry);            
					}
					else 
					_stprintf(fileEntry, _T("\\StringFileInfo\\%04X04B0\\%s"), 
					GetUserDefaultLangID(), csEntry);

					if (VerQueryValue(versionInfo,fileEntry,&retbuf,(UINT *)&vLen)) 
					{
						csRet = (TCHAR*)retbuf;

						csRet.MakeLower();

						if(0 <= csRet.Find(_T("wine")))
							fRet = TRUE;
					}
				}
			}

			UnlockResource( hGlobal );  
			FreeResource( hGlobal );  
			FreeLibrary(hLib);
		}
	}
	return fRet;
}

This code is mainly based on a publication on www.codeproject.com by luetz: http://www.codeproject.com/KB/cpp/GetLo ... play=Print.

I simply read the product name of the ntdll.dll which is "Wine" when running under wine.

Hope this helps, JonDoe

It's a really bad way to detect Wine by looking at resources.

If you really want to have a reliable sure way to detect Wine - look for Wine specific export(s) from that dll. But as mentioned before, make it a user overridable in case Wine gets fixed, or developers want to actually use your app to verify correct functionality.
