Hi,

1) Was it the correct approach?




I have not worked much with the tdi functions, but there used to be an
additional event to trap to get the receive data. This thread on
newsgroups might help
http://groups.google.co.in/groups?hl=en&lr=&ie=UTF-8&threadm=t0isduaft35l33%40corp.supernews.com&rnum=12&prev=/groups%3Fq%3Dtdi_receive%26start%3D10%26hl%3Den%26lr%3D%26ie%3DUTF-8%26selm%3Dt0isduaft35l33%2540corp.supernews.com%26rnum%3D12

2) Is there any encryption behind it?




No encryption that I know of, I guess you just have to wait on a
different event.





3) Can any one suggest a good
documentation for 98DDK.........................

<x-tab>        </x-tab>Roshan...
any suggestions?  I always went with the examples & the net
:-).





4) How can i get an NT/2000 DDK?
(I dont have an MSDN subscription)

<x-tab>        </x-tab>You can
order the current ddk (i.e. server 2003 ddk) from the url
http://www.microsoft.com/ddk
for only shipping charges. The server 2003 ddk includes the Windows 2000 ddk also. 
This is available for only a shipping charge of  $25 (payable by credit card) and will 
ship to India. :-)



<x-tab>        </x-tab>However, if you need the NT or 98  NT ddk, then you will have 
to order the costlier DDK suite (around $200 or so) or be a MSDN subscriber. 





Have a nice day,

Thanks JK for your reply 
  
A few months back i wrote a small TCP hooking VxD using Winasm and 98DDK. I hooked 
tdi_connect, tdi_receive, tdi_send etc...It was a dynamic VxD. I was trying to make my 
VC++ frontend to scan the buffer in tdi_receive. The IP and Port address i got was 
correct from tdi_connect but, but the buffer got through tdi_receive never contained 
any valid data. 
  
Tdi_ReceiveHook is 
----------Hook Procedure----------------- 
push ebp 
mov ebp, esp 
pushfd 
pushad 
mov edi, [ebp+10H]     --------------NDIS struct pointer 
mov edi, [edi+04H]      --------------pointer to data in NDIS struct 
------------------------edi  i suppose should be received data pointer--------------- 
----------transfer edi contents to VC++ frontend------------------ 
-------------Pop stuff---------------------------------------------- 
-------------return stuff-------------------------------------------- 
  
1) Was it the correct approach? 
2) Is there any encryption behind it? 
  
the real problem was that i had no other guidence except Izelon tutorials which comes 
along with winasm. 98DDK documentation was too bad. So i dont know if the code is 
correct.
