easiest is after getting the resource data in pData, write it to a MapData.md file in the dll path and just use the code.


but since that's probably not what you wish a second easiest method is to replace the std:fstream with a std:stringstream and load it with the contents of pData (don't ask me how, I don't make use of c++ much, I just see there is a stringstream object you could use with the same parents as fstream)

I have the following complete code in c++

Code:

    void GetMapData ()
    {
        MapPair NewMap;
        string TempString;
        BOOL SkipReadLine = FALSE;
   
        //------
   
        char buffer[MAX_PATH];
        std::fstream File;
        std::string  Dir;
   
        GetModuleFileNameA(GlobalhMod, buffer, MAX_PATH);
        Dir = buffer;
        Dir = Dir.substr(0, Dir.find_last_of("\\")+1);
        Dir += "MapData.text";
   
        File.open(Dir.c_str(), std::ios::in);
   
        if(!File.good())
        {
            MessageBox(GlobalhWnd, "MapData.md is not in your DLL directory.\rGame will be terminate.", "snsRush", MB_OK);
            TerminateProcess(GetCurrentProcess(), 0);
        }
   
        while (File.good())
        {
            MapData NewMapData;
            PortalData NewPortalData;
   
            if (!SkipReadLine)
                getline (File, TempString);
   
            NewMapData.MapID = atoi (TempString.substr (1, TempString.length() - 1).c_str());
   
            if (SkipReadLine)
            {
                SkipReadLine = FALSE;
                getline (File, TempString);
            }
   
            getline (File, TempString);
            NewMapData.Island = TempString.substr (7, TempString.length() - 7);
            if(strcmp(NewMapData.Island.c_str(), "1") != 0 &&strcmp(NewMapData.Island.c_str(), "2") != 0 && strcmp(NewMapData.Island.c_str(), "3") != 0 && strcmp(NewMapData.Island.c_str(), "4") != 0)
            {
                break;
            }
   
            getline (File, TempString);
            NewMapData.TopName = TempString.substr (8, TempString.length() - 8);
   
            getline (File, TempString);
            NewMapData.MapName = TempString.substr (8, TempString.length() - 8);
   
            File >> TempString;
   
            if (!strcmp (TempString.substr (0, 1).c_str(), "["))
            {
                SkipReadLine = TRUE;
                NewMap = MapPair (NewMapData.MapID, NewMapData);
                MsMap.insert (NewMap);
            }
            else
            {
                int NumMaps = atoi (TempString.substr (6, TempString.length() - 1).c_str());
                for (int i = 1; i <= NumMaps; i++)
                {
                    File >> NewPortalData.PortalName;
                    File >> NewPortalData.PortalType;
                    File >> NewPortalData.X;
                    File >> NewPortalData.Y;
                    File >> NewPortalData.ToMapID;
                    NewMapData.Portals.push_back (NewPortalData);
                }
   
                getline (File, TempString);
                NewMap = MapPair (NewMapData.MapID, NewMapData);
                MsMap.insert (NewMap);
            }
        }
        File.close ();
    }

The problem is that I do not want to have an external MapData.txt, rather I access it through a embedded text resource, which in this case I have no knowledge on doing so.

I have the following snippet which demonstrates to my knowledge on how to access a text resource; however, I do not know hot to modify the code above to implant this, but to still have the same functionality as the original code above.

Code:

    HRSRC hRes = FindResource(GetModuleHandle(NULL), MAKEINTRESOURCE(IDR_TEXT1), _T("TEXT"));
    DWORD dwSize = SizeofResource(GetModuleHandle(NULL), hRes);
    HGLOBAL hGlob = LoadResource(GetModuleHandle(NULL), hRes);
    const BYTE* pData = reinterpret_cast<const BYTE*>(::LockResource(hGlob));

Please take note that I am compiling with a MBCS.


Should be as simple as changing the cast from byte to char and using the result as the constructor for an istringstream, which will promote it to a string.

If I do this, how do I put it into the existing code(do I put istringstream in the File.open, and if so, then it appears to be easy!)?


I haven't studied your code very closely, and I certainly haven't tried to compile it, but yeah... should be as easy as just "std::istringstream File(pData);" and then the rest should work w/o any changes.
