Madshi's madCodeHook Hook WS2_32.dll in windows98/me

It worked with the lastest beta build of madCodeHook

But when I close the hooked application
will got an error window like this:

Runtime error 216 at 598036D6

Are you using Delphi or C++? In the latter case are you using the static or dynamic lib? Are you sure your code is correct? Try to use empty hook callback functions (that is only call the next function without doing anything else).

I use Delphi
I try to use empty hook callback function,It still got error like that
but in windows xp/2k it works fine

How does your (empty) code look like?

var
  sendNext : function( s       : Integer;
               buffer  : PByteArray;
               len     : Integer;
               flags   : Integer ):Integer; stdcall;
function sendCallback( s       : Integer;
               buffer  : PByteArray;
               len     : Integer;
               flags   : Integer ):Integer; stdcall;
begin
  Result := sendNext(s, buffer, len, flags);
end;

I'd like to see the whole code of the dll.

Also, which application shows that runtime error 216? Is it your own application or another one?

unit Hookfunc;

interface
 
uses
  Windows, Messages, SysUtils, madCodeHook, Dialogs,
  graphics;

type
  TByteArray = array[0..32767] of byte;
  PByteArray = ^TByteArray;

implementation

var
  sendNext : function( s       : Integer;
               buffer  : PByteArray;
               len     : Integer;
               flags   : Integer ):Integer; stdcall;
function sendCallback( s       : Integer;
               buffer  : PByteArray;
               len     : Integer;
               flags   : Integer ):Integer; stdcall;
begin
  Result := sendNext(s, buffer, len, flags);
end;

procedure MyDLLHandler(Reason: Integer);
var
  FHandle   : LongWORD;
begin
  case Reason of
    DLL_PROCESS_ATTACH:
    begin
      HookAPI('WS2_32.dll', 'send', @sendCallback, @sendNext);
    end;
  end;
end;

begin
  DLLProc := @MyDLLHandler;
  MyDLLhandler(DLL_PROCESS_ATTACH);
end.

Also, which application shows that runtime error 216? Is it your own application or another one?

looks is my dll shows that runtime error

But your dll is loaded in all processes. Inside of which process does it show that box?

P.S: Please remove Dialogs from the uses clause. It blows up the size of your dll quite much, cause it links in lots of VCL stuff.

P.P.S: Also remove graphics from the uses clause. You should try to avoid any VCL imports in a hook dll.

I removed the graphics and Dialogs in uses clause
still got that error:(

that dll use CreateProcessEx load into one processes...not loaded in all processes

What if you remove the HookAPI call? Does the error then still occur? If it does, can you please compile the hook dll with madExcept? Thanks.

Oh I am sorry,
It's my mistake
I add madExcept in the dll file
I remove it is ok
looks madExcept can't work with dll?

madExcept generally should work with dlls just fine. Using it for hook dlls which are used for system wide injection is not a good idea. But using it for a hook dll, which only gets injected into one process (as you do) should normally work.

So the problem exists only when you compile the dll with madExcept? That's strange...
