Amazingly I just found the original files .. after such a long time .. 😀 .. I updated the links at the end of the post, so the source code is now available on GitHub and you can view the image on a working image hosting site.

Yes, sadly RapidShare.com stopped working five years ago, but the displayed code in solution two is basically what was in the source code ZIP and should give you a good understanding how to solve this problem.

I don't get your question.

Do you want to create a stored procedure that takes TID as parameter and returns the first column where it finds TID and omit any other columns where TID can be found?

Can you please clarify your question?

Hello, your hosting machine has IIS and the application is started? You can also turn on debug output to show you a call trace and you can remote debug the application, if you have to rights on the host system. Personally, I prefer the remote debug method as most stuff works very differently when it's no longer running on the local machine. Good luck!

Hello, you will need a trigger for that (CREATE TRIGGER..), just look it up in the help files or on the net, it's pretty intuitive.. can you please not write the question title in all capitals next time, thank you.

Change "if (R == 0 && G == 0 && B == 0)" in the isBlack routine to something like "if (R < 50 && G < 50 && B < 50)" (20% of 255 ~ 50) and you got a threshold.

Hi, can you please provide some code that shows how you are trying to do this as well as the specific error message you get.

Well, a colored pixel is not black, right? For black pixels the red, green and blue values are zero. Negate that statement and you know the pixel is a colored one.

Okay, I will give you a more detailed idea of how I think you could do this, please refer to my 2nd solution.

Man, next time I post something, I will copy it before I do so, half of what I wrote was gone after posting.. anyway, I wrote it again and hope it helps!

Hello, just a question..

Your write:

printf("enter the no of elements:");
scanf("%d",&n);

And then:

for(i=0;i<=n;i++) scanf("%d",&a[i]);

Which will scan for n+1 inputs. Is that intended or did you mean:

for(i=0;i < n;i++) scanf("%d",&a[i]);

I just did a quick search on Google and found this article here (http://stackoverflow.com/questions/153572/parser-generator-that-outputs-c-sharp-given-a-bnf-grammar). It's old, but it has some really good suggestions and even an SQL grammar in Backus-Naur notation. Personally, I would start with the lexer generator that ships with the Visual Studio SDK as it sounds pretty interesting to me.. I didn't even know they had that.

The links: SQL grammar (http://savage.net.au/SQL/sql-2003-2.bnf)
Microsoft scanner generator (http://msdn.microsoft.com/en-us/vstudio/cc837016.aspx)

I am sure you can find more like this, if you do a more extensive Google search.

I just read your question again and realized that you are using HTML files.. =( I am not sure how I missed that, maybe because I was browsing for questions with an ASP.NET tag and was kinda convinced your question was about that too, sorry. Well, at least you know now how I would to it, if you were using ASP, right? =D

You definitely won’t be able to determine who was responsible for the car accident from a picture.. no chance. You would need much more information and some kind of simulation how the accident happened. I have to ask it.. did you think about a possible implementation or the question at all?

Please, rebuild the project and try again.
