Hopefully said bug causes his system to overload, and a rm -rf /his/job/ must be preformed.

First, you post the same question 3 times, and in different fourms as well. Well call that second, the cross-posting that is. Third, you don't know how to use a debugger. Fourth, you put 'help!' in your subject. Everyone that posts a question needs help, jackass. Fifth, you can't read the forum rules. This isn't for questions. It's for coding horrors, which yours is, but in a different context.
So basically, that makes you a 5x idiot. Quit crop-dusting our forums with your crap question. No one cares. Had you been civilized about it, you may have gotten some help. As a matter of fact, someone did answer you. They now wish they didn't, and I'm sure they wouldn't have if they'd seen your blatant disregard for the rules. Most people won't. Oh man I wish my device was ready.

I feel nice today, so I will help you once here, thats it though, next time, try the correct forum.

Thanks for your kind. I removed that code you mentioned, but the problem still exists. In fact, I thought it is fine for define unsaved-value="0", because I have already make this attribute as incremental identiy in database. While debugging the code, the object which I intend to save in session.save(u) does have correct values. And it works fine if I just work with one table. Am I right? Please tell me if you got time.

You can't use user as a table name and have it work with NHibernate unless you do some special stuff in your mapping file...
In your user.hbm.xml do this:
//note the square brackets around the table name.
<class name="ConsoleApplication1.user, ConsoleApplication1" table="[user]">
That'll fix your problem...

Dear Richard,
That is what the problem is. I really appreciate to what you did. It has been tough time for me. You saved me. Thank you again.

I learned from a senior system's analyst today that you should never pass a class you created back from a webservice. Since he was wanting to pass a dataset back and also the exception message if one occurred, he decided it was better to send back an empty dataset and have the webservice write a file to the users machine if it generated an error! Why couldn't I think of that!!!

I assume you mean that he was just old or out of touch. Why on earth does he think you can't pass a class back? More importantly, why's he passing a DataSet back? DataSets are really bad practice when you're developing a web service - they are bloated and not interoperable with other platforms without extra development effort. Mind you, there are so many WTFs in his solution that I can't begin to allude to the horror in it.

He might be a senior system analyst just by virtue of his experience in date and time calendar. But adjudging him through his wise (pros) and vices (cons) in programming, he should truly be classified as a junior most crap  .

Hello folks!
I did a little spy-out (with Reflector(c)) the DataView-Class. And found the following:
public IEnumerator GetEnumerator()
{
DataRowView[] array = new DataRowView[this.Count];
this.CopyTo(array, 0);
return array.GetEnumerator();
}
Do I understand right: Each foreach-Initialisation it will copy all its Content to a new array, and return that arrays Enumerator??
And if I break the foreach-loop at second element all these DataRowViews came into live in vain?
|
|

|

Yeah, must be some old code.
Try not to use foreach if you expect to break the iteration.

Thats the first time I hear this advice. It results in some little pretty ugly workarounds, doesn't it?
No - I expect the coders to make their enumerators efficient and keep on enjoing the better design of foreach (if available).
|

Actually, it's the result of one of the tenets of iteration development. If you have to use a break statement (or god forbid a goto) to get out of a loop, you are using the wrong type of loop. Have a look at Code Complete by Steve McConnell to find more gems like this.

Hm, I'm real puzzled. Whenever I was searching anything in any Enumerable I used foreach. And broke the loop when I did find, what I wanted.
Sample - how you would improve this little thing?
public TreeNode GetNodeByText(TreeNode Parent, string Txt) {
foreach (TreeNode Nd in Parent.Nodes) {
if (Nd.Text == Txt) return Nd;
}
return null;
}
And how do you think is ICollection<T>.Contains() implemented in hundreds of classes?

Well, try not to, but some times you may need to.
Having said that, you may be able to iterate with the index of the nodes.
Or, if you do more searching than adding/removing, you could use a Dictionary<string,TreeNode> to speed up the search.

So - if somebody else writes bad code you think it's your duty to also write bad code? Just because somebody gives you a foreach doesn't mean that you have to use it in every case. Take a look at the alternatives such as the do/while loop.

So do what others do and buy a copy of the book. You won't regret it.

lol, you are supposed to ignore using break/return completely so you have something to optimize later:

I could never bring myself to intentionally build a "speedup loop".
