winapi - Can I Write Version Information API For Both CHAR And WCHAR? -


i'm little bit short of reaching goal.

getfileversioninfosize() working fine along other 2 functions getfileversioninfo() , verqueryvalue(). add more features make complete.

i've coded run on wchar , know making run char make sense?

is there way around code once , work both?

also, there way enumerate contents of \\stringfileinfo\\lang-codepage\\* ?

dword getfileversioninfo3(const tchar *pszfilepath, std::vector<std::pair<std::wstring, std::wstring>> *lplist) {     dword               dwsize = 0;     byte                *pbversioninfo = null;     vs_fixedfileinfo    *pfileinfo = null;     uint                pulenfileinfo = 0;      dwsize = getfileversioninfosize(pszfilepath, null);     if (dwsize == 0)     {         printf("\nerror in getfileversioninfosize: %d\n", getlasterror());         return 1;     }      pbversioninfo = new byte[dwsize];     memset(pbversioninfo, '\0', dwsize);      if (!getfileversioninfo(pszfilepath, 0, dwsize, pbversioninfo))     {         printf("\nerror in getfileversioninfo: %d\n", getlasterror());         delete[] pbversioninfo;         return 1;     }      if (!verqueryvalue(pbversioninfo, text("\\"), (lpvoid*)&pfileinfo, &pulenfileinfo))     {         printf("\nerror in verqueryvalue: %d\n", getlasterror());         delete[] pbversioninfo;         return 1;     }      if (!verqueryvalue(pbversioninfo, text("\\varfileinfo\\translation"), (lpvoid*)&lptranslate, &pulenfileinfo))     {         printf("\nerror in verqueryvalue: %d\n", getlasterror());         return 1;     }      std::vector<std::wstring>::iterator itr;     std::vector<std::wstring> wlist;     wlist.clear();     wlist.push_back(l"filedescription");     wlist.push_back(l"internalname");     wlist.push_back(l"originalfilename");     wlist.push_back(l"companyname");     wlist.push_back(l"fileversion");     wlist.push_back(l"productname");     wlist.push_back(l"productversion");     wlist.push_back(l"legalcopyright");      char fileentry[1024];     (int = 0; < (pulenfileinfo / sizeof(struct langandcodepage)); i++)     {         sprintf_s(fileentry, 1024, "\\stringfileinfo\\%04x%04x\\",         lptranslate[i].wlanguage,         lptranslate[i].wcodepage);          lplist->push_back(std::pair<std::wstring, std::wstring>(l"file: ", pszfilepath));          std::string s1(fileentry);         (itr = wlist.begin(); itr != wlist.end(); itr++)         {             std::wstring item = *itr;             std::wstring wstr;             wstr.append(s1.begin(), s1.end());             wstr.append(item);             lpvoid lpbuffer = null;             uint   dwbytes = 0;             bool bres = verqueryvalue(pbversioninfo, wstr.c_str(), (lpvoid*)&lpbuffer, &dwbytes);             if (!bres)             {                 continue;             }             lptstr wsresult;             wsresult = (lptstr)lpbuffer;             lplist->push_back(std::pair<std::wstring, std::wstring>(item, wsresult));         }     }      return 0; }

since using tchar, use std:::basic_string<tchar> instead of std::wstring match. otherwise, drop tchar , use wchar everything.
