I want to get version info from executable, so I checked MSDN and wrote something like this:

zusammenfalten · markieren

Delphi-Quellcode:

  Size := GetFileVersionInfoSize(PChar(AFileName), hWnd);
  if Size > 0 then
  begin
    GetMem(Buffer, Size);
    try
      if GetFileVersionInfo(PChar(AFileName), hWnd, Size, Buffer) then
      begin
        if VerQueryValue(Buffer, '\', Pointer(FixedFileInfo), L) then
        begin
          if VerQueryValue(Buffer, PChar('\VarFileInfo\Translation'), Pointer(pD), L) then
          begin
            Translation := IntToHex(pD^, 8);
            Temp := Copy(Translation, 5, 4);
            if StrToIntDef('$' + Temp, 0) = 0 then
              Temp := IntToHex(1033, 4)
            ;
            Translation := Temp + Copy(Translation, 1, 4);
          end
          else
            Translation := '040904E4'
          ;

          // Here query for values

I checked on 16, 32 and 64 bit files and working well in most cases, but not for all For example for firefox.exe returns nulls (but query for translation passes) What's wrong with this?

You already know of a scenario that is going to fail. And you have the might of the debugger at your fingertips. What's stopping you from first finding out which call returns NULL?

So, I told

VerQueryValue(Buffer, PChar('\VarFileInfo\Translation')...

is success. Problem is with

VerQueryValue(Buffer, PChar('\StringFileInfo\' + Translation + '\(specified entries in table here)')

- here it fails on some files, looks like can't access, because wrong translation code

Heres an example how I'm doing it (see attachement).. its ripped from my component library and displays some of the version info in a memo.

Nice, thanks! It woreking very well.

I did something wrong with translation I see.
