Did you import the files into your own project or open it with their csproj/sln file?

asdf9009 26-Jul-12 13:17pm

i import the file into my own project file..not theirs

You need to add a reference to the NBug.dll in your own project (right click References->Add Reference...->Browse and find it there).

Hii tried to add the NBug.dll file, but VS stated that the file could not be added.

What version of .Net are you targeting? (right click your project->Properties->Application tab, value in "Target framework:")

asdf9009 26-Jul-12 13:55pm

i just change the solution name file to "Nighthawk "
and now i have even complicated issues..lol
im using .NET 4.0

lewax00 26-Jul-12 13:58pm

Then I have no idea why this should fail, the DLL appears to be a .Net one. You may have better luck just importing their csproj into your solution and working from there.

asdf9009 26-Jul-12 13:59pm

ok...i tried

lewax00 26-Jul-12 14:10pm

Oh, some of those should be fixed by adding "using System.Windows;" at the top I believe (at least the reference to Application).

Have you looked at what he is trying to get working?
http://code.google.com/p/nighthawk/
"ARP spoofing (IPv4) and RA spoofing (IPv6) over local network
Password sniffing for most common HTML form fields (name-based matching), HTTP basic authentication, FTP, POP3, SMTP, IMAP
Basic SSL stripping (doesn't work on HTTPS-only sites) and cookie stripping
Quick attack mode
Windows Phone application for remote access to sniffer results (HawkWP)"

"This software may be used only for educational and security testing purposes with your network administrator's consent. The author takes no responsibility for improper (or even illegal) usage, data loss or other damage that might occur during its usage."

I can't believe that anyone with his technical abilities is interested in legitimate uses...

Please dont judge me before you know the facts!
I think i should tell you that..im actually a university student who currently doing a programming project,
..im doing all these for "Academic purposes" ,i have nothing to say if you dont believe me..

lewax00 26-Jul-12 15:45pm

Hmm...well I guess is doesn't matter too much now, I don't think I could offer anymore help anyways. (Not that I can say much, I almost got a job in high school by playing around with similar tools...)

asdf9009 27-Jul-12 1:41am

anyway...i re download the source file through a source control software...its working now =)

Solution 1

In basic terms, it's to do with the namespace. I think the idea was that the NBug classes would be compiled into a single DLL and then referenced by your application.

Try this: put the edit point inside the word "NBug" and a small blue line will appera under the "N".
Hover the mouse over the blue line, and a drop down list will appear.
Open the drop down, and you will be presented with solutions to the problem.
Select the first one - it should add an appropriate using statement, and it should compile.

it doesnt work

OriginalGriff 26-Jul-12 13:59pm

That isn't a helpful problem report! :laugh:
It's like calling the garage, saying "my car broke" and hanging up - the mechanics don't know who you are,m whare you are, or what is wrong with your car, so you are going to be waiting a long time for help to come to you!

asdf9009 26-Jul-12 14:02pm

anyway...now im looking deeper into the issues, attempt to solve it ,.
yea..it sounds like "my car broke" , because the driver just got his license or the car owner just got his new car not long ago =)
so have to spend some time to understand and learn how to solve the problem

OriginalGriff 26-Jul-12 14:06pm

Sometimes the best thing you can do is scrap the car and get another!
Have you considered recreating your project from scratch and adding stuff until you are somewhere sensible?
If you create a backup directory, and copy the whole project in when it compiles and BEFORE you make changes, you can quickly and easily undo any problems.

asdf9009 26-Jul-12 15:11pm

Hi
i download the source code file one by one...not download in a package..

OriginalGriff 26-Jul-12 15:16pm

I have now looked at what Nighthawk is and am no longer willing to assist you.
I cannot believe that anyone with your demonstrated technical abilities is intending to use this for any legitimate purpose.

asdf9009 26-Jul-12 15:25pm

Whether u believe it or not, its for education purposes.
