Filestream - Add a File to an other File

[cdkiller]

hy,

i have the following problems. i have a txt and a dll file.

now i want that the dll file will add at the end of the txt file.
i mean that i want to insert a dll file in a txt file at the end.

i have tried it with a filestream. but it doesnt do it what it should.

can someone post a function ?

thanks...

I got no idea why anyone wants to do, what you want to do, however, you should show us your code and we will be able to help you to fix it ;)

okay,

this is my code:

it should add a dll file to an other file.

Delphi-Quellcode:

var
fs,fs2 : TFileStream;
Buffer: Pointer;
Buffer2: Pointer;
filename: string;
begin
if OpenDialog1.Execute then filename := OpenDialog1.FileName;
fs := TFileStream.Create(filename, fmOpenReadWrite);
fs.ReadBuffer(Buffer^,Sizeof(Buffer^));
fs.Seek(0,soFromEnd);

fs2 := TFilestream.Create('sf_wrapper.dll', fmOpenRead);
fs2.ReadBuffer(Buffer2^,Sizeof(Buffer2^));
fs.WriteBuffer(Buffer2^,Sizeof(Buffer2^));

fs.Free;
fs2.Free;

where is the error or can you fix it ?

Althoug I don't know for what reason you might need this, here's my answer :zwinker:

Delphi-Quellcode:

fs2.ReadBuffer(Buffer2^,Sizeof(Buffer2^));

where is the error or can you fix it ?

What do you expect "Sizeof(Buffer2^)" to be? you should use "FS2.Size" instead of it... I didn't check if this works cause I'd use the function "CopyFrom":

Delphi-Quellcode:

var
  fs,fs2  : TFileStream;
begin
  if OpenDialog1.Execute then
  try
    fs       := TFileStream.Create(OpenDialog1.FileName, fmOpenReadWrite);
    fs2      := TFilestream.Create('myDLL.dll',          fmOpenRead);
    fs.Seek (fs.Size,soFromBeginning);
    fs2.Seek(0,      soFromBeginning);
    fs.CopyFrom(fs2,fs2.Size);
  finally
    fs.Free;
    fs2.Free;
  end;
end;

(By the way: there were a few 'errors' in your code :wink:, e.g. you don't need to read sth. from FS.)
