The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

hi experts,

it's my first time i try to develop an driver for windows xp.
iv downloaded the DDK (www.microsoft.com/ddk/) for windows read all information
found a simple example and build than.

the source is simple:

#include "ntddk.h"

VOID OnUnload( IN PDRIVER_OBJECT DriverObject )
{
DbgPrint("Unload driver \n");
}

NTSTATUS DriverEntry(IN PDRIVER_OBJECT theDriverObject,IN PUNICODE_STRING theRegistryPath)
{
DbgPrint("Driver Loaded \n ");

theDriverObject->DriverUnload = OnUnload;
return STATUS_SUCCESS;
}

have ofcourse the
SOURCE

TARGETNAME=myfirstdriver
TARGETPATH=OBJ
TARGETTYPE=DRIVER
SOURCES=halloworld.c

and the MAKEFILE

#
# DO NOT EDIT THIS FILE!!! Edit .\sources. if you want to add a new source
# file to this component. This file merely indirects to the real make file
# that is shared by all the driver components of the Windows NT DDK
#

!INCLUDE $(NTMAKEENV)\makefile.def

all takes from example

as i actually told i build the driver without problems.

Install Driver successed...
Start Driver i get :
1275 ERROR_DRIVER_BLOCKED = This driver has been blocked from loading

the funny think is the compiled driver works on some maschiens!.... only not on this i have to develop on :(.......
