How to determine Delphi Application Version

Question

Want to obtain Delphi Application build number and post into title bar

Answer 1

Here is how I do it. I put this in almost all of my small utilities:

procedure GetBuildInfo(var V1, V2, V3, V4: word);
var
  VerInfoSize, VerValueSize, Dummy: DWORD;
  VerInfo: Pointer;
  VerValue: PVSFixedFileInfo;
begin
  VerInfoSize := GetFileVersionInfoSize(PChar(ParamStr(0)), Dummy);
  if VerInfoSize > 0 then
  begin
      GetMem(VerInfo, VerInfoSize);
      try
        if GetFileVersionInfo(PChar(ParamStr(0)), 0, VerInfoSize, VerInfo) then
        begin
          VerQueryValue(VerInfo, '\', Pointer(VerValue), VerValueSize);
          with VerValue^ do
          begin
            V1 := dwFileVersionMS shr 16;
            V2 := dwFileVersionMS and $FFFF;
            V3 := dwFileVersionLS shr 16;
            V4 := dwFileVersionLS and $FFFF;
          end;
        end;
      finally
        FreeMem(VerInfo, VerInfoSize);
      end;
  end;
end;

function GetBuildInfoAsString: string;
var
  V1, V2, V3, V4: word;
begin
  GetBuildInfo(V1, V2, V3, V4);
  Result := IntToStr(V1) + '.' + IntToStr(V2) + '.' +
    IntToStr(V3) + '.' + IntToStr(V4);
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Form1.Caption := Form1.Caption + ' - v' + GetBuildInfoAsString;
end;
