Thread: Load values from end of file (exe)

Hello.

I'm writing an application which saving some values to EXE file.
I wrote 'SaveToEXE' function.

Now I've got a problem.
How to read saved values in EXE file? Values are stored at the end of the file. How to read this string:



I found the function LoadFromEXE, but in Delphi:

Code:

FUNCTION LoadFromFile(FName: string): string;
var
F: File of Byte;
I: Integer;
begin
Result := '';
AssignFile(F, FName);
FileMode := fmOpenRead;
Reset(F);
try
Seek(F, FileSize(F) - SizeOf(I));
BlockRead(F, I, SizeOf(I));
if (I < SizeOf(I)) or (I > FileSize(F)) then
Exit;
Seek(F, FileSize(F) - I);
SetLength(Result, I - SizeOf(I));
BlockRead(F, Result[1], Length(Result));
XXX := Result;
finally
CloseFile(F);
end;
end;

How to do it in C++?

// Sorry for my english.

What does SaveToEXE look like? Knowing will make it a lot easier to getLoadFromEXE correct.
Also, do you know about program resources? They are the correct way to deal with this kind of thing.

You'd want to do it if you're writing a virus that appends its own code and resources to the end of an executable.
