begin
  try
    try
      IniFile := TIniFile.Create(IniFileName);
      FileStream := TFileStream.Create(IniFileName, fmopenread or
        fmShareExclusive);
      IniFile.WriteBinaryStream('IniSction', IniFileName, FileStream);

Hi,

Because you're calling the same file and are opening the
file stream in exclusive mode.
But the file is already in use from the Ini class, so... you
can't have it!

HTH,

Andrew

DeerBear,thanks
i use this,it can work,      
FileStream := TFileStream.Create(IniFileName, fmopenread or
        fmShareDenyNone);

i call this
button.click:
AddToIni('d:\1.bmp');
when i first call this founction,this can only write "[IniSction]
kk",when i second call this founction,it can write some data,eg:
[IniSction]
kk=5B6D797365635D0D0A6B6B3D0D0A

but how i get the source,
function TResClass.GetResFile(IniFileName: string): boolean;
var
  IniFile: TIniFile;
  IniSction: string;
  FileMemStream: TMemoryStream;
begin
  try
    try
      IniFile := TIniFile.Create(IniFileName);
      FileMemStream := TMemoryStream.Create;
      IniFile.ReadBinaryStream('mysec', 'kk', FileMemStream);
      FileMemStream.SaveToFile('d:\gogo.bmp');
    except
      result := false;
      exit;
    end;
  finally
    IniFile.Free;
    IniFile := nil;
    FileMemStream.Free;
  end;
  result := true;
end;

it can not get the bmp,and the ini file limit 64k?

thanks!
