Re: Re[2]: DeviceIOControl ... again ...

Soya,

That was a couple of years ago when I worked with NDIS drivers, so details 
might be vague. Anyhow, I'll try to help (though it is largely offtopic for 
JEDI list).
1. You mentioned you used DDK 2600 build (which is Windows XP DDK 
fortunately), so if you run the test sample under Windows XP the protocol 
driver should be preinstalled (look into %SystemRoot%\SYSTEM32\Drivers for 
ndisuio.sys file);

2. Since the moment they have release XP they have changed mind and renamed 
protocol driver in DDK from ndisuio to ndisprot. That was made for purpose. 
There were introduced many painful problems made by some not very careful 
programmers once they started to rely either on ndisuio existence, or used the 
modified ndisuio sample without modifying the resultant driver name. Just 
don't do it!

3. Anyhow. Let try to make WINDDK sample (ndis\ndisuio\test) to work. Please 
read carefully instructions in the ndisprot\ndisprot.htm, build the user-level 
test sample (build -czg), start the installed version of a driver with 
commands mentioned in the readme, and check UIOTEST sample.

If you were careful enough you should be ok till the moment. And could 
reproduce the same tests with your Delphi derivative.

For a future: if you want to modify a bit ndisuio.sys driver - change the 
target protocol driver name first. Or better yet - start from the WINDDK 
3790.1106 (aka Windows 2003 Server SP1 DDK) version. It is already renamed, 
and you won't get problems with built-in protocol driver.

If you would still the problems in modifications of your NDIS protocol 
driver - go ask to the proper forums:
1. The only NDIS specific-list - [email protected] ;
2. driver-developments list on OSR.com - news://lists.osr.com/ntdev/
3. Driver-developments list on Microsoft.com - 
news://msnews.microsoft.com/microsoft.public.development.device.drivers (and 
several others);

Good Luck,
Timur
